These tests are run with js-test-driver (http://code.google.com/p/js-test-driver/). Running 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: Run: $ java -jar ./auto_tests/lib/JsTestDriver-1.3.3c.jar --port 9876 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-1.3.3c.jar --tests all Debugging tests --------------- This is a bit of a hack, but you can also run tests manually inside the browser using auto_tests/misc/local.html. Once you've opened that page, open up the JavaScript console and run something like: new SimpleDrawingTestCase().runTest("testDrawSimpleRangePlusOne") to run just one test. This is useful for seeing the dygraph that the test creates, setting breakpoints, etc. Please don't rely on it as proof that your tests pass; the command-line is the reference for ensuring Dygraphs automated tests pass. (This is a specialized version of the instructions found at http://code.google.com/p/js-test-driver/wiki/GettingStarted. They're listed as a courtesy, but you really should get to understand js-test-driver, which has lots of powerful features.)
