See the License for the specific language governing permissions and limitations under the License. --> <p><em>Compatibility Test Suite (CTS)</em> is a free, commercial-grade test suite used by device manufacturers to help ensure that their devices are compatible, and to report test results for validations. CTS is intended to be integrated into the daily workflow (such as through a continuous build system) of the engineers building a device. CTS's intent is to reveal incompatibilities early on, and ensure that the software remains compatible throughout the development process.</p> <p>CTS is available for <a href="/docs/compatibility/cts/downloads">download</a> as a binary or as source in the <a href="https://android.googlesource.com/platform/cts/">Android Open Source Project (AOSP)</a>. CTS runs on a desktop machine and executes test cases directly on attached devices or an emulator.</p> <p>CTS contains two major software components:</p> <ul> <li> The <a href="/docs/core/tests/tradefed"><em>Trade Federation</em></a> test harness runs on your desktop machine and manages test execution. Trade Federation offers the ability to <a href="/docs/core/tests/tradefed/testing/through-suite/android-test-tuning">shard tests</a> across multiple Devices Under Test (DUTs). You may also use the <a href="/docs/core/tests/tradefed/testing/through-suite/suite-retry">suite retry</a> feature to retry the failures only rather than the full suites, greatly reducing re-run time. </li> <li> The individual test cases are executed on the DUT. The test cases are written in Java as JUnit tests and packaged Android .apk files to run on the actual device target. </li> </ul> <aside class="note"><strong>Note:</strong> The Android Open Source Project accepts contributions to improve CTS just as for any other component. In fact, improving the coverage and quality of CTS test cases is one of the best ways to help Android. To make contributions to CTS, follow the same process to <a href="/docs/setup/contribute/submit-patches">Submit a patch</a>. </aside> <h2 id="verifier" data-text="Compatibility Test Suite Verifier (CTS Verifier)" tabindex="-1">Compatibility Test Suite Verifier (CTS Verifier)</h2> <p>The <em>Compatibility Test Suite Verifier (CTS Verifier)</em> is a supplement to CTS available for <a href="/docs/compatibility/cts/downloads">download</a>. The CTS Verifier provides tests for APIs and functions that cannot be tested on a stationary device without manual input (for example, audio quality and accelerometer) or manual positioning.</p> <p>The CTS Verifier is a tool for manual testing and includes the following software components:</p> <ul> <li> <p>The CTS Verifier app that is executed on the DUT (and on a 2nd device for distance measurement requirements) and collects the results. <li> <p>The executable(s) or script(s) that are executed on the desktop machine to provide data or additional control for some test cases in the CTS Verifier app.</p> </li> </ul> <h2 id="workflow" data-text="Workflow" tabindex="-1">Workflow</h2> <div class="attempt-right" style="width:383px"> <img src="/static/docs/compatibility/cts/images/cts-0.png" alt="CTS flow" height="340px" id="figure1"> <p class="img-caption"> <strong>Figure 1.</strong> How to use CTS </p> </div> <p>This diagram summarizes CTS workflow.

The CTS contains a utility to check those API signatures against the APIs available on the device.
