Automated tests
When working on a patch for DevTools, there's almost never a reason not to add a new test. If you are fixing a bug, you probably should write a new test to prevent this bug from occurring again. If you're implementing a new feature, you should write new tests to cover the aspects of this new feature.
Ask yourself:
- Are there enough tests for my patch?
- Are they the right types of tests?
We use three suites of tests:
xpcshell: Unit-test style of tests. No browser window, only a JavaScript shell. Mostly testing APIs directly.- Chrome mochitests: Unit-test style of tests, but with a browser window. Mostly testing APIs that interact with the DOM.
- DevTools mochitests: Integration style of tests. Fires up a whole browser window with every test and you can test clicking on buttons, etc.
To run all DevTools tests, regardless of suite type:
./mach test devtools/*
Have a look at the child pages for more specific commands for running only a single suite or single test in a suite.
