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`](xpcshell.md): Unit-test style of tests. No browser window, only a JavaScript shell. Mostly testing APIs directly. +* [Chrome mochitests](mochitest-chrome.md): Unit-test style of tests, but with a browser window. Mostly testing APIs that interact with the DOM. +* [DevTools mochitests](mochitest-devtools.md): 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: + +```bash +./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. |
