"""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 (in /data/local/tmp). 3. Environment: 3.1. chrome/unit_tests requires (via chrome_paths.cc) a directory named: /data/local/tmp/chrome/test/data 3.2. page_cycler_tests have following requirements, 3.2.1 the following data on host: /tools/page_cycler /data/page_cycler 3.2.2. two data directories to store above test data on device named: /data/local/tmp/tools/ (for database perf test) /data/local/tmp/data/ (for other perf tests) 3.2.3. a http server to serve http perf tests. The http root is host's /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.
