These tests are run with js-test-driver. To use: This is a specialized version of the instructions found at the js-test-driver Getting Started wiki. They're listed as a courtesy, but you really should get to understand js-test-driver, which has lots of powerful features. To run tests:

• Start a terminal window at the dygraphs root directory (one directory up from here.)
• From there, you start the test server and capture at least one slave browser.
  1. Run java -jar ./auto_tests/lib/JsTestDriver-1.3.2.jar --port 9876
  2. Open http://localhost:9876/capture in the browser you want to use for your test.
• Run the tests with java -jar ./auto_tests/lib/JsTestDriver-1.3.2.jar --tests all

This is a bit of a hack, but you can also run tests locally, and manually, by using this testing page. Please don't rely on it as proof that your tests pass; the command-line is the reference for ensuring Dygraphs automated tests pass.
