The harness (test.py) operates as follows. First it locates executable browsers (or symlinks or scripts) named "[browser][version]", e.g. "firefox4". It then launches the located browsers and asks them to load the file test_slave.html. At the same time, test.py sets up an HTTP server on localhost:8080 (there's a race condition here currently ;). After test_slave loads in the browser(s), it fetches the task manifest (test_manifest.json). The entries in the manifest specify which PDF to load and how many times to cycle through page rendering. This will probably evolve over time. test_slave then performs the requested tasks and POSTs the results back to test.py, which saves them. When all the results of for a task are in, test.py checks them. There are three types of tests currently. "==" tests compare the rendering of a PDF against a master copy. This is not yet implemented because setting up a master copy is complicated. "fbf" tests render all a PDF's pages, then go back to page 1 and render all pages a second time. The renderings from the first round must match the ones from the second round. "load" tests just check that a PDF's pages load without errors. Currently the test harness will only launch a "firefox4" target. This can be a bash script in your pdf.js checkout, pdf.js/firefox4, something like the following #!/bin/bash dist="/path/to/firefox4/installation" profile=`mktemp -dt 'pdf.js-test-ff-profile-XXXXXXXXXX'` $dist/firefox -no-remote -profile $profile $* rm -rf $profile (Yes, this script doesn't clean up properly on early termination.) It's possible to run the tests in a normal browsing session, but that might be annoying. With that set up, run the harness like so python test.py If all goes well, you'll see all "TEST-PASS" messages printed to stdout. If something goes wrong, you'll see "TEST-UNEXPECTED-FAIL" printed to stdout.
