Since that time, no other language (I know of) has decided to copy this idea, but somehow the Java developers are in love with checked exceptions. Here, I am going to "try" to convince you that checked-exceptions, even though look like a good idea at first glance, are actually not a good idea at all:<br /> <br /> <strong>Empirical Evidence</strong><br /> <br /> Let's start with an observation of your code base. Look through your code and tell me what percentage of catch blocks do rethrow or print error? My guess is that it is in high 90s. I would go as far as 98% of catch blocks are meaningless, since they just print an error or rethrow the exception which will later be printed as an error. The reason for this is very simple. Most exceptions such as FileNotFoundException, IOException, and so on are sign that we as developers have missed a corner case. The exceptions are used as away of informing us that we, as developers, have messed up. So if we did not have checked exceptions, the exception would be throw and the main method would print it and we would be done with it (optionally we would catch all exceptions in the main log them if we are a server).<br /> <br /> Checked exceptions force me to write catch blocks which are meaningless: more code, harder to read, and higher chance that I will mess up the rethrow logic and eat the exception.<br /> <br /> <strong>Lost in Noise</strong><br /> <br /> Now lets look at the 2-5% of the catch blocks which are not rethrow and real interesting logic happens there. Those interesting bits of useful and important information is lost in the noise, since my eye has been trained to skim over the catch blocks. I would much rather have code where a catch would indicate: "pay, attention! here, something interesting is happening!", rather than, "it is just a rethrow." Now, if we did not have checked exceptions, you would write your code without catch blocks, test your code (you do test right?) and realize that under some circumstances an exception is throw and deal with it by writing the catch block. In such a case forgetting to write a catch block is no different than forgetting to write an else block of the if statement. We don't have checked ifs and yet no one misses them, so why do we need to tell developers that FileNotFound can happen. What if the developer knows for a fact that it can not happen since he has just placed the file there, and so such an exception would mean that your filesystem has just disappeared! (and your application is not place to handle that.)<br /> <br /> Checked exception make me skim the catch blocks as most are just rethrows, making it likely that you will miss something important.<br /> <br /> <strong>Unreachable Code</strong><br /> <br /> I love to write tests first and implement as a consequence of tests. In such a situation you should always have 100% coverage since you are only writing what the tests are asking for. But you don't! It is less than 100% because checked exceptions force you to write catch blocks which are impossible to execute. Check this code out:<br /> <pre>bytesToString(byte[] bytes) { ByteArrayOutputStream out = new ByteArrayOutputStream(); try { out.write(bytes); out.close() return out.toSring(); } catch (IOException e) { // This can never happen! // Should I rethrow? Eat it? Print Error? } }</pre> <br /> ByteArrayOutputStream will never throw IOException! You can look through its implementation and see that it is true! So why are you making me catch a phantom exception which can never happen and which I can not write a test for? As a result I cannot claim 100% coverage because of things outside my control.<br /> <br /> Checked exceptions create dead code which will never execute.<br /> <br /> <strong>Closures Don't Like You</strong><br /> <br /> Java does not have closures but it has visitor pattern. Let me explain with concrete example. I was creating a custom class loader and need to override load() method on MyClassLoader which throws ClassNotFoundException under some circumstances. I use ASM library which allows me to inspect Java bytecodes. The way ASM works is that it is a visitor pattern, I write visitors and as ASM parses the bytecodes it calls specific methods on my visitor implementation. One of my visitors, as it is examining bytecodes, decides that things are not right and needs to throw a ClassNotFondException which the class loader contract says it should throw. But now we have a problem. What we have on a stack is MyClassLoader -> ASMLibrary -> MyVisitor. MyVisitor wants to throw an exception which MyClassLoader expects but it can not since ClassNotFoundException is checked and ASMLibrary does not declare it (nor should it). So I have to throw RuntimeClassNotFoundException from MyVisitor which can pass through ASMLibrary which MyClassLoader can then catch and rethrow as ClassNotFoundException.<br /> <br /> Checked exception get in the way of functional programing.<br /> <br /> <strong>Lost Fidelity</strong><br /> <br /> Suppose java.sql package would be implemented with useful exception such as SqlDuplicateKeyExceptions and SqlForeignKeyViolationException and so on (we can wish) and suppose these exceptions are checked (which they are). We say that the SQL package has high fidelity of exception since each exception is to a very specific problem. Now lets say we have the same set up as before where there is some other layer between us and the SQL package, that layer can either redeclare all of the exceptions, or more likely throw its own. Let's look at an example, Hibernate is object-relational-database-mapper, which means it converts your SQL rows into java objects. So on the stack you have MyApplication -> Hibernate -> SQL. Here Hibernate is trying hard to hide the fact that you are talking to SQL so it throws HibernateExceptions instead of SQLExceptions. And here lies the problem. Your code knows that there is SQL under Hibernate and so it could have handled SqlDuplicateKeyException in some useful way, such as showing an error to the user, but Hibernate was forced to catch the exception and rethrow it as generic HibernateException. We have gone from high fidelitySqlDuplicateKeyException to low fidelity HibernateException. An so MyApplication can not do anything. Now Hibernate could have throw HibernateDuplicateKeyException but that means that Hibernate now has the same exception hierarchy as SQL and we are duplicating effort and repeating ourselves.<br /> <br /> Rethrowing checked exceptions causes you to lose fidelity and hence makes it less likely that you could do something useful with the exception later on.<br /> <br /> <strong>You can't do Anything Anyway</strong><br /> <br /> In most cases when exception is throw there is no recovery. We show a generic error to the user and log an exception so that we con file a bug and make sure that that exception will not happen again. Since 90+% of the exception are bugs in our code and all we do is log, why are we forced to rethrow it over and over again.<br /> <br /> It is rare that anything useful can be done when checked exception happens, in most case we die with error! Therefor I want that to be the default behavior of my code with no additional typing.<br /> <br /> <strong>How I deal with the code</strong><br /> <br /> Here is my strategy to deal with checked exceptions in java:<br /> <ul><br /> <li>Always catch all checked exceptions at source and rethrow them as LogRuntimeException.<br /><ul><br /> <li>LogRuntimeException is my runtime un-checked exception which says I don't care just log it.</li> <br /> <li>Here I have lost Exception fidelity.</li> </ul> </li> <br /> <li>All of my methods do not declare any exceptions</li> <br /> <li>As I discover that I need to deal with a specific exception I go back to the source where LogRuntimeException was thrown and I change it to <Specific>RuntimeException (This is rarer than you think)<br /><ul><br /> <li>I am restoring the exception fidelity only where needed.</li> </ul> </li> <br /> <li>Net effect is that when you come across a try-catch clause you better pay attention as interesting things are happening there.<br /><ul><br /> <li>Very few try-catch calluses, code is much easier to read.</li> <br /> <li>Very close to 100% test coverage as there is no dead code in my catch blocks.</li> </ul> </li> </ul> <span itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://plus.google.com/116899029375914044550' itemprop='url'/> </span> </script> <noscript> <div> By <a href="http://misko.hevery.com/">Miško Hevery</a></div> <div> <br /></div> Once upon a time Java created an experiment called checked-exceptions, you know, you have to declare exceptions or catch them.

Check this code out:<br /> <pre>bytesToString(byte[] bytes) { ByteArrayOutputStream out = new ByteArrayOutputStream(); try { out.write(bytes); out.close() return out.toSring(); } catch (IOException e) { // This can never happen! // Should I rethrow? Eat it? Print Error? } }</pre> <br /> ByteArrayOutputStream will never throw IOException! You can look through its implementation and see that it is true! So why are you making me catch a phantom exception which can never happen and which I can not write a test for? As a result I cannot claim 100% coverage because of things outside my control.<br /> <br /> Checked exceptions create dead code which will never execute.<br /> <br /> <strong>Closures Don't Like You</strong><br /> <br /> Java does not have closures but it has visitor pattern. Let me explain with concrete example. I was creating a custom class loader and need to override load() method on MyClassLoader which throws ClassNotFoundException under some circumstances. I use ASM library which allows me to inspect Java bytecodes. The way ASM works is that it is a visitor pattern, I write visitors and as ASM parses the bytecodes it calls specific methods on my visitor implementation. One of my visitors, as it is examining bytecodes, decides that things are not right and needs to throw a ClassNotFondException which the class loader contract says it should throw. But now we have a problem. What we have on a stack is MyClassLoader -> ASMLibrary -> MyVisitor. MyVisitor wants to throw an exception which MyClassLoader expects but it can not since ClassNotFoundException is checked and ASMLibrary does not declare it (nor should it). So I have to throw RuntimeClassNotFoundException from MyVisitor which can pass through ASMLibrary which MyClassLoader can then catch and rethrow as ClassNotFoundException.<br /> <br /> Checked exception get in the way of functional programing.<br /> <br /> <strong>Lost Fidelity</strong><br /> <br /> Suppose java.sql package would be implemented with useful exception such as SqlDuplicateKeyExceptions and SqlForeignKeyViolationException and so on (we can wish) and suppose these exceptions are checked (which they are). We say that the SQL package has high fidelity of exception since each exception is to a very specific problem. Now lets say we have the same set up as before where there is some other layer between us and the SQL package, that layer can either redeclare all of the exceptions, or more likely throw its own. Let's look at an example, Hibernate is object-relational-database-mapper, which means it converts your SQL rows into java objects. So on the stack you have MyApplication -> Hibernate -> SQL. Here Hibernate is trying hard to hide the fact that you are talking to SQL so it throws HibernateExceptions instead of SQLExceptions. And here lies the problem. Your code knows that there is SQL under Hibernate and so it could have handled SqlDuplicateKeyException in some useful way, such as showing an error to the user, but Hibernate was forced to catch the exception and rethrow it as generic HibernateException. We have gone from high fidelitySqlDuplicateKeyException to low fidelity HibernateException. An so MyApplication can not do anything. Now Hibernate could have throw HibernateDuplicateKeyException but that means that Hibernate now has the same exception hierarchy as SQL and we are duplicating effort and repeating ourselves.<br /> <br /> Rethrowing checked exceptions causes you to lose fidelity and hence makes it less likely that you could do something useful with the exception later on.<br /> <br /> <strong>You can't do Anything Anyway</strong><br /> <br /> In most cases when exception is throw there is no recovery. We show a generic error to the user and log an exception so that we con file a bug and make sure that that exception will not happen again. Since 90+% of the exception are bugs in our code and all we do is log, why are we forced to rethrow it over and over again.<br /> <br /> It is rare that anything useful can be done when checked exception happens, in most case we die with error! Therefor I want that to be the default behavior of my code with no additional typing.<br /> <br /> <strong>How I deal with the code</strong><br /> <br /> Here is my strategy to deal with checked exceptions in java:<br /> <ul><br /> <li>Always catch all checked exceptions at source and rethrow them as LogRuntimeException.<br /><ul><br /> <li>LogRuntimeException is my runtime un-checked exception which says I don't care just log it.</li> <br /> <li>Here I have lost Exception fidelity.</li> </ul> </li> <br /> <li>All of my methods do not declare any exceptions</li> <br /> <li>As I discover that I need to deal with a specific exception I go back to the source where LogRuntimeException was thrown and I change it to <Specific>RuntimeException (This is rarer than you think)<br /><ul><br /> <li>I am restoring the exception fidelity only where needed.</li> </ul> </li> <br /> <li>Net effect is that when you come across a try-catch clause you better pay attention as interesting things are happening there.<br /><ul><br /> <li>Very few try-catch calluses, code is much easier to read.</li> <br /> <li>Very close to 100% test coverage as there is no dead code in my catch blocks.</li> </ul> </li> </ul> <span itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://plus.google.com/116899029375914044550' itemprop='url'/> </span> </noscript> </div> </div> <div class='share'> <span class='twitter-custom social-wrapper' data-href='http://twitter.com/share?text=Google Testing Blog:Checked exceptions I love you, but you have to go&url=https://testing.googleblog.com/2009/09/checked-exceptions-i-love-you-but-you.html&via=googletesting'> <img alt='Share on Twitter' height='24' src='https://www.gstatic.com/images/icons/material/system/2x/post_twitter_black_24dp.png' width='24'/> </span> <span class='fb-custom social-wrapper' data-href='https://www.facebook.com/sharer.php?u=https://testing.googleblog.com/2009/09/checked-exceptions-i-love-you-but-you.html'> <img alt='Share on Facebook' height='24' src='https://www.gstatic.com/images/icons/material/system/2x/post_facebook_black_24dp.png' width='24'/> </span> </div> <div class='comment-container'> <i class='comment-img material-icons'>  </i> <a href='https://testing.googleblog.com/2009/09/checked-exceptions-i-love-you-but-you.html#comments' style='font-weight: 500; text-decoration: underline;'>34 comments</a> </div> <div class='post-footer'> <div class='cmt_iframe_holder' data-href='https://testing.googleblog.com/2009/09/checked-exceptions-i-love-you-but-you.html' data-viewtype='FILTERED_POSTMOD'></div> <a href='https://plus.google.com/112374322230920073195' rel='author' style='display:none;'> Google </a> <div class='label-footer'> <span class='labels-caption'> Labels: </span> <span class='labels'> <a class='label' href='https://testing.googleblog.com/search/label/Java' rel='tag'> Java </a> , <a class='label' href='https://testing.googleblog.com/search/label/Misko%20Hevery' rel='tag'> Misko Hevery </a> </span> </div> </div> </div> <div class='post' data-id='8689734607920519872' itemscope='' itemtype='http://schema.org/BlogPosting'> <h2 class='title' itemprop='name'> <a href='https://testing.googleblog.com/2009/09/plague-of-entropy.html' itemprop='url' title='The Plague of Entropy'> The Plague of Entropy </a> </h2> <div class='post-header'> <div class='published'> <span class='publishdate' itemprop='datePublished'> Monday, September 14, 2009 </span> </div> </div> <div class='post-body'> <div class='post-content' itemprop='articleBody'> <script type='text/template'> By James Whittaker<div><br />Mathematically entropy is a measure of uncertainty.

I know it is imperfect one, as one is about design and the other is about manufacturing, but indulge me, the lessons are very similar.<br /> <br /> A piece of software is like a car. Lets say you would like to test a car, which you are in the process of designing, would you test is by driving it around and making modifications to it, or would you prove your design by testing each component separately? I think that testing all of the corner cases by driving the car around is very difficult, yes if the car drives you know that a lot of things must work (engine, transmission, electronics, etc), but if it does not work you have no idea where to look. However, there are some things which you will have very hard time reproducing in this end-to-end test. For example, it will be very hard for you to see if the car will be able to start in the extreme cold of the north pole, or if the engine will not overheat going full throttle up a sand dune in Sahara. I propose we take the engine out and simulate the load on it in a laboratory.<br /> <br /> We call driving car around an end-to-end test and testing the engine in isolation a unit-test. With unit tests it is much easier to simulate failures and corner cases in a much more controlled environment. We need both tests, but I feel that most developers can only imagine the end-to-end tests.<br /> <br /> But lets see how we could use the tests to design a transmission. But first, little terminology change, lets not call them test, but instead call them stories. They are stories because that is what they tell you about your design. My first story is that:<br /> <ul><br /> <li>the transmission should allow the output shaft to be locked, move in same direction (D) as the input shaft, move in opposite (R) or move independently (N)</li> </ul> <br /> Given such a story I could easily create a test which would prove that the above story is true for any design submitted to me. What I would most likely get is a transmission which would only have a single gear in each direction. So lets write another story<br /> <ul><br /> <li>the transmission should allow the ratio between input and output shaft to be [-1, 0, 1, 2, 3, 4]</li> </ul> <br /> Again I can write a test for such a transmission but i have not specified how the forward gear should be chosen, so such a transmission would most likely be permanently stuck in 1st gear and limit my speed, it will also over-rev the engine.<br /> <ul><br /> <li>the transmission should start in 1st and than switch to higher gear before the engine reaches maximum revolutions.</li> </ul> <br /> This is better, but my transmission would most likely rev the engine to maximum before it would switch, and once it would switch to higher gear and I would slow down, it would not down-shift.<br /> <ul><br /> <li>the transmission should down shift whenever the engine RPM fall bellow 1000 RPMs</li> </ul> <br /> OK, now it is starting to drive like a car, but still the limits for shifting really are 1000-6000 RPMs which is not very fuel efficient way to drive your car.<br /> <ul><br /> <li>the transmission should up-shift whenever the estimated fuel consumption at a higher gear ration is better than the current one.</li> </ul> <br /> So now our engine will not rev any more but it will be a lazy car since once the transmission is in the fuel efficient mode it will not want to down-shift<br /> <ul><br /> <li>the transmission should down-shift whenever the gas pedal is depressed more than 50% and the RPM is lower than the engine's peak output RPM.</li> </ul> <br /> I am not a transmission designer, but I think this is a decent start.<br /> <br /> Notice how I focused on the end result of the transmission rather than on testing specific internals of it. The transmission designer would have a lot of levy in choosing how it worked internally, Once we would have something and we would test it in the real world we could augment these list of stories with additional stories as we discovered additional properties which we would like the transmission to posses.<br /> <br /> If we would decide to change the internal design of the transmission for whatever reason we would have these stories as guides to make sure that we did not forget about anything. The stories represent assumptions which need to be true at all times. Over the lifetime of the component we can collect hundreds of stories which represent equal number of assumption which is built into the system.<br /> <br /> Now imagine that a new designer comes on board and makes a design change which he believes will improve the responsiveness of the transmission, he can do so because the existing stories are not restrictive in how, only it what the outcome should be. The stories save the designer from breaking an existing assumption which was already designed into the transmission.<br /> <br /> Now lets contrast this with how we would test the transmission if it would already be build.<br /> <ul><br /> <li>test to make sure all of the gears work</li> <br /> <li>test to make sure that the engine is not allowed to over-rev</li> </ul> <br /> It is hard now to think about what other tests to write, since we are not using the tests to drive the design. Now, lets say that someone now insist that we get 100% coverage, we open the transmission up and we see all kinds of logic, and rules and we don't know why since we were not part of the design so we write a test<br /> <ul><br /> <li>at 3000 RPM input shaft, apply 100% throttle and assert that the transmission goes to 2nd gear.</li> </ul> <br /> Tests like that are not very useful when you want to change the design, since you are likely to break the test, without fully understanding why the test was testing that specific conditions, it is hard to know if anything was broken if the tests is red.. That is because the tests does not tell a story any more, it only asserts the current design. It is likely that such a test will be in the way when you will try to do design changes. The point I am trying to make is that there is huge difference between writing tests before or after. When we write tests before we are:<br /> <ul><br /> <li>creating a story which is forcing a particular design decision.</li> <br /> <li>tests are a collection of assumptions which needs to be true at all times.</li> </ul> <br /> when we write tests after the fact we:<br /> <ul><br /> <li>miss a lot of reasons why things are done in particular way even if we have 100% coverage</li> <br /> <li>test are often brittle because they are tied to particulars of the current implementation</li> <br /> <li>tests are just snapshots and don't tell a story of why the component does something, only that it does.</li> </ul> <br /> For this reason there are huge differences in quality when writing assumptions as stories before (which force design to emerge) or writing tests after which take a snapshot of a given design. <span itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://plus.google.com/116899029375914044550' itemprop='url'/> </span> </script> <noscript> <div> by <a href="http://misko.hevery.com/">Miško Hevery</a></div> <div> <br /></div> I would like to make an analogy between building software and building a car.

When we write tests before we are:<br /> <ul><br /> <li>creating a story which is forcing a particular design decision.</li> <br /> <li>tests are a collection of assumptions which needs to be true at all times.</li> </ul> <br /> when we write tests after the fact we:<br /> <ul><br /> <li>miss a lot of reasons why things are done in particular way even if we have 100% coverage</li> <br /> <li>test are often brittle because they are tied to particulars of the current implementation</li> <br /> <li>tests are just snapshots and don't tell a story of why the component does something, only that it does.</li> </ul> <br /> For this reason there are huge differences in quality when writing assumptions as stories before (which force design to emerge) or writing tests after which take a snapshot of a given design. <span itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://plus.google.com/116899029375914044550' itemprop='url'/> </span> </noscript> </div> </div> <div class='share'> <span class='twitter-custom social-wrapper' data-href='http://twitter.com/share?text=Google Testing Blog:It is not about writing tests, its about writing stories&url=https://testing.googleblog.com/2009/09/it-is-not-about-writing-tests-its-about.html&via=googletesting'> <img alt='Share on Twitter' height='24' src='https://www.gstatic.com/images/icons/material/system/2x/post_twitter_black_24dp.png' width='24'/> </span> <span class='fb-custom social-wrapper' data-href='https://www.facebook.com/sharer.php?u=https://testing.googleblog.com/2009/09/it-is-not-about-writing-tests-its-about.html'> <img alt='Share on Facebook' height='24' src='https://www.gstatic.com/images/icons/material/system/2x/post_facebook_black_24dp.png' width='24'/> </span> </div> <div class='comment-container'> <i class='comment-img material-icons'>  </i> <a href='https://testing.googleblog.com/2009/09/it-is-not-about-writing-tests-its-about.html#comments' style='font-weight: 500; text-decoration: underline;'>8 comments</a> </div> <div class='post-footer'> <div class='cmt_iframe_holder' data-href='https://testing.googleblog.com/2009/09/it-is-not-about-writing-tests-its-about.html' data-viewtype='FILTERED_POSTMOD'></div> <a href='https://plus.google.com/112374322230920073195' rel='author' style='display:none;'> Google </a> <div class='label-footer'> <span class='labels-caption'> Labels: </span> <span class='labels'> <a class='label' href='https://testing.googleblog.com/search/label/Misko%20Hevery' rel='tag'> Misko Hevery </a> </span> </div> </div> </div> <div class='post' data-id='2441538521820777322' itemscope='' itemtype='http://schema.org/BlogPosting'> <h2 class='title' itemprop='name'> <a href='https://testing.googleblog.com/2009/09/7th-plague-and-beyond.html' itemprop='url' title='The 7th Plague and Beyond'> The 7th Plague and Beyond </a> </h2> <div class='post-header'> <div class='published'> <span class='publishdate' itemprop='datePublished'> Wednesday, September 02, 2009 </span> </div> </div> <div class='post-body'> <div class='post-content' itemprop='articleBody'> <script type='text/template'> By James Whittaker<div><br /></div><div>Sorry I haven't followed up on this, let the excuse parade begin: A) My new book just came out and I have spent a lot of time corresponding with readers.
