 This github repository adds Emscripten testing harness for pthreads. To run the Emscripten pthreads tests, perform the following:
 
-1. Adjust the Firefox Nightly pref dom.workers.maxPerDomain in about:config to at least 40 to allow that many simultaneous threads to run (some tests need it)
-2. Prepare Firefox Nightly prefs to be emrun-friendly by setting http://kripken.github.io/emscripten-site/docs/compiling/Running-html-files-with-emrun.html#running-web-pages-in-firefox
-3. Edit the file posixtestsuite/emcc/run_emcc_tests.py and configure the --browser=xx directive in the invocation of the 'emrun' cmd (line 24) to point to your pthreads-enabled Firefox Nightly build.
-4. Add directory posixtestsuite/emcc/ to PATH.
-5. Navigate to posixtestsuite/conformance/interfaces/ as the current directory.
-6. Make sure to close all existing instanced of Firefox tabs and processes, because the test runner will forcibly terminate browser processes during the run.
-7. Run 'run_all_tests.py'
+1. Set the environment EMSCRIPTEN_BROWSER to point to the executable of the target browser to run the test suite in.
+2. Close all existing instanced of Firefox tabs and processes, because the test runner will forcibly terminate browser processes during the run.
+3. Navigate to /path/to/posixtestsuite/conformance/interfaces/ as the current directory.
+4. Run '/path/to/posixtestsuite/emcc/run_all_tests.py'. This will run all the tests found in the subdirectories of the current working directory.
