 # Running the tests
 
 pdf.js comes with browser-level regression tests that allow one to probe
 whether it's able to successfully parse PDFs, as well as compare its output
 against reference images, pixel-by-pixel.
 
-To run the tests, first configure the browser manifest file at:
+More information about running the tests can be found on the
-
+[contributor wiki page](https://github.com/mozilla/pdf.js/wiki/Contributing).
-    test/resources/browser_manifests/browser_manifest.json
-
-Sample manifests for different platforms are provided in that directory.
-
-To run all the bundled tests, type:
-
-    $ make test
-
-and cross your fingers. Different types of tests are available, see the test
-manifest file at:
-
-    test/test_manifest.json
-
-The test type `eq` tests whether the output images are identical to reference 
-images. The test type `load` simply tests whether the file loads without 
-raising any errors.
-
-
-### Running tests through our bot
-
-If you are a reviewer, you can use our remote bot to issue comprehensive tests 
-against reference images before merging pull requests.

 # ShellJS - Unix shell commands for Node.js [![Build Status](https://secure.travis-ci.org/arturadib/shelljs.png)](http://travis-ci.org/arturadib/shelljs)

++ _This project is young and experimental. Use at your own risk._
++ _Major API change as of v0.0.4: `ls()` and `find()` now return arrays._
 
 ShellJS is a **portable** (Windows included) implementation of Unix shell commands on top of the Node.js API. You can use it to eliminate your shell script's dependency on Unix while still keeping its familiar and powerful commands.
