See the License for the specific language governing permissions and limitations under the License. --> <p>Android Open Source Project (AOSP) provides several tools and test suites for testing various parts of your implementation. Before using the pages in this section, you should be familiar with the following terms:</p> <dl> <dt><em>Android-compatible device</em></dt> <dd>A device that can run any third-party app written by third-party developers using the Android SDK and NDK. Android-compatible devices must adhere to the requirements of the <a href="#CDD">Compatibility Definition Document (CDD)</a> and pass the <a href="#cts">Compatibility Test Suite (CTS)</a>. Android-compatible devices are eligible to participate in the Android ecosystem, which includes potential licensure of Google Play, potential licensure of the <a href="#gms">Google Mobile Services (GMS)</a> suite of app and APIs, and use of the Android trademark. Anyone is welcome to use the Android source code, but to be considered part of the Android ecosystem, a device must be Android compatible.</dd> <dt id="artifacts"><em>artifact</em></dt> <dd>A build-related log that enables local troubleshooting.</dd> <dt id="CDD"><em>Compatibility Definition Document (CDD)</em></dt> <dd>A document that enumerates the software and hardware requirements for an Android-compatible device.</dd> <dt id="cts"><em>Compatibility Test Suite (CTS)</em></dt> <dd><p>A free, commercial-grade test suite, available for download as a binary or as source in AOSP. The CTS is a set of unit tests designed to be integrated into your daily workflow. The intent of CTS is to reveal incompatibilities, and ensure that the software remains compatible throughout the development process.</p> <p>CTS and platform tests aren&#39;t mutually exclusive. Here are some general guidelines:</p> <ul> <li>If a test is asserting correctness of framework API functions or behaviors, and the test should be enforced across OEM partners, it should be in CTS.</li> <li>If a test is intended to catch regressions during platform development, and might require privileged permission to carry out, and might be dependent on implementation details (as released in AOSP), it should be a platform test.</li> </ul></dd> <dt id="gms"><em>Google Mobile Services (GMS)</em></dt> <dd><p>A collection of Google apps and APIs that can be preinstalled on devices.</p></dd> <dt id="gtest"><em>GoogleTest (GTest)</em></dt> <dd><p>A C++ testing and mocking framework. GTest binaries typically access lower-level abstraction layers or perform raw IPC against various system services. The testing approach for GTest is usually tightly coupled with the service being tested. CTS contains the GTest framework.</p></dd> <dt id="instrumentation"><em>instrumentation test</em></dt> <dd><p>A special test execution environment launched by the <code translate="no" dir="ltr">am instrument</code> command, where the targeted app process is restarted and initialized with basic app context, and an instrumentation thread is started inside the app process virtual machine. CTS contains instrumentation tests.</p></dd> <dt id="logcat"><em>Logcat</em></dt> <dd><p>A command-line tool that creates a log of system messages, including stack traces of when the device throws an error and messages that you have written from your app with the <code translate="no" dir="ltr">Log</code> class.</p></dd> <dt id="logging"><em>logging</em></dt> <dd><p>Using a log to keep track of computer system events, such as errors. Logging in Android is complex due to the mix of standards used that are combined in the Logcat tool.</p></dd> <dt id="postsubmit"><em>postsubmit test</em></dt> <dd><p>An Android test that is performed when a new patch is committed to a common kernel branch. By entering <code translate="no" dir="ltr">aosp_kernel</code> as a partial branch name, you can see a list of kernel branches with results available. For example, results for <code translate="no" dir="ltr">android-mainline</code> can be found at <a href="https://ci.android.com/builds/branches/aosp_kernel-common-android-mainline/grid">https://ci.android.com/builds/branches/aosp_kernel-common-android-mainline/grid</a>.</p></dd> <dt id="presubmit"><em>presubmit test</em></dt> <dd><p>A test used to prevent failures from being introduced into the common kernels.</p></dd> <dt id="presubmit"><em>Trade Federation</em></dt> <dd><p>Also called Tradefed, a continuous test framework designed for running tests on Android devices.
