Fundamentally, the framework\n lets you annotate tests using the `@Test` annotation and the app finds and runs\n those tests.\n\n- *OmniLab Android Test Station* is an app that lets you run tests\n in a GUI.\n\nThis page explains how to run automated tests using Trade Federation. For\ninstructions on running tests using OmniLab Android Test Harness, see\n[OmniLab Android Test Station](/docs/core/tests/development/android-test-station/ats-user-guide).\n\nRun all automated CTS tests\n---------------------------\n\nTrade Federation contains the *CTS console*, a command-line interface for\nrunning tests. To run the entire automated CTS test suite:\n\n1. Ensure you have followed the instructions in [Set up CTS automated testing](/docs/compatibility/cts/setup).\n2. On your test workstation, launch the CTS console by running the `cts-tradefed` script from the folder where the CTS package has been unzipped:\n\n ./android-cts/tools/cts-tradefed\n\n The CTS console displays a cursor for you to type CTS commands\n (`cts-tradefed \u003e`).\n3. The `cts` test plan contains all of the automated CTS tests. Execute the\n following command to run the `cts` test plan:\n\n run cts\n\n The automated CTS tests execute. Note the following:\n - Android 13 and higher support multidevice testing. These tests run\n automatically only when sharding is used. For further information on sharding,\n see [Improve test execution time](#improve). If you want to run these tests\n manually, see [Run multidevice tests](#multi-device-testing).\n\n - Whenever running CTS, press **ctrl+c** to stop the existing CTS console\n and then rerun the CTS console.\n\n - You can't run multiple CTS versions on single host because each opens\n with an existing open location code (OLC) server.\n\n4. View test results. For more information, see [Interpret CTS results](/docs/compatibility/cts/interpret).\n\n5. If this is your first test run, there might be tests that fail due to issues beyond your control. For example, a network connection might be slow or a GPS signal might be weak. Rerun (retry) the tests until all test modules are completed and the test failure numbers are the same between the last two retry sessions:\n\n run retry --retry \u003cvar translate=\"no\"\u003esession_number\u003c/var\u003e`\n\n | **Note:** For implementation details for CTS retry, see [Use suite retry](/docs/core/tests/tradefed/testing/through-suite/suite-retry).\n | **Note:** For instructions on how to run a retry session on Android 10 or lower, see [Run CTS automated tests (AOSP 10 or lower)](/docs/compatibility/cts/run-older).\n6. After tests failures are consistent across retries, focus on debugging\n the remaining failed tests. For information on troubleshooting test\n results, see\n [Triage test failures](/docs/compatibility/cts/interpret#triaging-test-failures)\n and\n [Troubleshoot CTS tests](/docs/compatibility/cts/troubleshooting).\n\n| **Note:** For a list of all CTS console commands, see [CTS v2 command console](/compatibility/cts/command-console-v2).\n\nRun CTS for multiscreen devices\n-------------------------------\n\nIf your device is running Android 11 or 12, and your device has multiple\nscreens, you must run the `cts-foldable` test plan separately: \n\n run cts-foldable\n\nPassed or failed test cases for alternate screen mode are appended with the\nvalue from `display_mode`, for example, `testcase1[display_mode=0]`.\n| **Note:** For instructions on how to run the `cts-foldable` test plan for Android 10 or lower, see [Run CTS automated tests (Android 10 or lower)](/docs/compatibility/cts/run-older).\n\nRun multidevice tests (Android 15 or lower)\n-------------------------------------------\n\nExecute the following command to run the `cts-multidevice` test plan: \n\n run cts-multidevice\n\nRun individual test plans\n-------------------------\n\nInstead of running all test plans at once, you can run individual test plans.\nThis option is useful to save time and to focus on a specific set of tests.\nTo run an individual test plan:\n\n1. Identify the name of the test plan you want to run by executing the `list modules` command.\n\n | **Note:** For instructions on how to identify the module on Android 10 or lower, see [Run CTS automated tests (Android 10 or lower)](/docs/compatibility/cts/run-older).\n2. Run the test plan:\n\n run cts --plan \u003cvar translate=\"no\"\u003etest_module_or_plan_name\u003c/var\u003e\n\nImprove test execution time\n---------------------------\n\nIf you want to improve test execution time, you can shard tests across multiple\ndevices. Sharding requires the host to connect at least two devices, but six or\nmore devices are recommended for efficiency.\n\nTo shard tests on Android 11 or higher, run: \n\n run cts --shard-count \u003cvar translate=\"no\"\u003enumber_of_shards\u003c/var\u003e\n\nAdditionally, before running your tests for validation you can improve test\nexecution time by using the CTS `run cts-dev` command. This command skips\npreconditions, device-information collection, and all system status checkers.\nIt also runs the tests on only a single ABI."]]
