Peptest is a Mozilla automated testing harness for running responsiveness tests. These tests measure how long events spend away from the event loop.

Running Tests

Currently tests are run from the command line with python. Peptest currently depends on some external Mozilla python packages, namely: mozrunner, mozprocess, mozprofile, mozinfo, mozlog, mozhttpd and manifestdestiny.

See running tests for more information.
