| """Runs all the native unit tests. |
| |
| 1. Copy over test binary to /data/local on device. |
| 2. Resources: chrome/unit_tests requires resources (chrome.pak and en-US.pak) |
| to be deployed to the device. We use the device's $EXTERNAL_STORAGE as the |
| base dir (which maps to Context.getExternalFilesDir()). |
| 3. Environment: |
| 3.1. chrome/unit_tests requires (via chrome_paths.cc) a directory named: |
| $EXTERNAL_STORAGE + /chrome/test/data |
| 3.2. page_cycler_tests have following requirements, |
| 3.2.1 the following data on host: |
| <chrome_src_dir>/tools/page_cycler |
| <chrome_src_dir>/data/page_cycler |
| 3.2.2. two data directories to store above test data on device named: |
| $EXTERNAL_STORAGE + /tools/ (for database perf test) |
| $EXTERNAL_STORAGE + /data/ (for other perf tests) |
| 3.2.3. a http server to serve http perf tests. |
| The http root is host's <chrome_src_dir>/data/page_cycler/, port 8000. |
| 3.2.4 a tool named forwarder is also required to run on device to |
| forward the http request/response between host and device. |
| 3.2.5 Chrome is installed on device. |
| 4. Run the binary in the device and stream the log to the host. |
| 4.1. Optionally, filter specific tests. |
| 4.2. Optionally, rebaseline: run the available tests and update the |
| suppressions file for failures. |
| 4.3. If we're running a single test suite and we have multiple devices |
| connected, we'll shard the tests. |
| 5. Clean up the device. |
| |
| Suppressions: |
| |
| Individual tests in a test binary can be suppressed by listing it in |
| the gtest_filter directory in a file of the same name as the test binary, |
| one test per line. Here is an example: |
| |
| $ cat gtest_filter/base_unittests_disabled |
| DataPackTest.Load |
| ReadOnlyFileUtilTest.ContentsEqual |
| |
| This file is generated by the tests running on devices. If running on emulator, |
| additonal filter file which lists the tests only failed in emulator will be |
| loaded. We don't care about the rare testcases which succeeded on emuatlor, but |
| failed on device. |
