| """Runs a script that can run as an isolate (or not). |
| |
| The main requirement is that |
| |
| --isolated-script-test-output=[FILENAME] |
| |
| is passed on the command line to run_isolated_script_tests. This gets |
| remapped to the command line argument --write-full-results-to. |
| |
| 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 sent down via the --test-list |
| argument. |
| |
| 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. |
