-Running the main part of the test suite. Don't forget to run the other parts!
-
- sanity - tests for first run, etc., modifies ~/.emscripten
- benchmark - run before and after each set of changes before pushing to
- master, verify no regressions
- browser - runs pages in a web browser
-
-There are also commands to run specific subsets of the test suite:
-
- browser sockets - runs websocket networking tests
- browser audio - runs audio tests in a web browser (requires human verification)
-
-To run one of those parts, do something like
-
- python tests/runner.py sanity
-
-To run a specific set of tests, you can do things like
-
- python tests/runner.py o1
-
-(that runs the o1 (-O1) tests). You can run individual tests with
-
- python tests/runner.py test_hello_world
-
-Combinations work too, for example
-
- python tests/runner.py browser.test_sdl_image
-
-In the main test suite, you can run all variations (O0, O1, O2, etc.) of
-an individual test with
-
- python tests/runner.py ALL.test_hello_world
