| """Runs isolate bundled Telemetry unittests. |
| |
| This script attempts to emulate the contract of gtest-style tests |
| invoked via recipes. The main contract is that the caller passes the |
| argument: |
| |
| --isolated-script-test-output=[FILENAME] |
| |
| json is written to that file in the format produced by |
| common.parse_common_test_results. |
| |
| Optional argument: |
| |
| --isolated-script-test-filter=[TEST_NAMES] |
| |
| is a double-colon-separated ("::") list of test names, to run just that subset |
| of tests. This list is parsed by this harness and remapped to multiple arguments |
| passed to the target script. |
| |
| This script is intended to be the base command invoked by the isolate, |
| followed by a subsequent Python script. It could be generalized to |
| invoke an arbitrary executable. |
