Simple test runner
These tests can be run in parallel using nose, for example
nosetests --processes=4 -v -s tests/runner.py
will use 4 processes. To install nose do something like
|pip install nose| or |sudo apt-get install python-nose|.
Note however that emcc now uses multiple cores when optimizing,
so you may prefer to use fewer cores here.

==============================================================================
Running the main part of the test suite. Don't forget to run the other parts!
A recommended order is:
sanity - tests for first run, etc., modifies ~/.emscripten
(the main test suite)
other - tests separate from the main suite
browser - runs pages in a web browser
interactive - runs interactive browser tests that need human verification, and could not be automated
sockets - runs websocket networking tests
benchmark - run before and after each set of changes before pushing to
master, verify no regressions
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 asm2
(that runs the asm2 (asm.js, -O2) 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
Debugging: You can run
EM_SAVE_DIR=1 python tests/runner.py ALL.test_hello_world
in order to save the test runner directory, in /tmp/emscripten_temp. All files
created by the test will be present there. You can also use EMCC_DEBUG to
further debug the compiler itself, which works outside of the test suite as
well: EMCC_DEBUG=1 will emit emcc-* files in that temp dir for each stage
of the compiler, while EMCC_DEBUG=2 will emit even more files, one for each
js optimizer phase.
