| """Runner for web-platform-tests |
| |
| The runner has several design goals: |
| |
| * Tests should run with no modification from upstream. |
| |
| * Tests should be regarded as "untrusted" so that errors, timeouts and even |
| crashes in the tests can be handled without failing the entire test run. |
| |
| * For performance tests can be run in multiple browsers in parallel. |
| |
| The upstream repository has the facility for creating a test manifest in JSON |
| format. This manifest is used directly to determine which tests exist. Local |
| metadata files are used to store the expected test results. |
