Gaia is Mozilla's Phone UX for the Boot to Gecko (B2G) project.

Boot to Gecko aims to create a complete, standalone operating system for the open web.

See INSTALL file in B2G repository for instructions on building and running B2G. To try out Gaia on desktop, see

https://wiki.mozilla.org/Gaia/Hacking

Unit tests for an app go in apps/<APP>/test/unit/.

To run all the unit tests with B2G Desktop:

1. Run DEBUG=1 make

2. Run make test-agent-server &

3. Run B2G Desktop and open the Test Agent app

4. Run make test-agent-test

   or make test-agent-test APP=<APP> to run unit tests for a specific app

   or make test-agent-test TESTS=<PATH/TO/TESTFILE.JS> to run unit tests in a specific file

More importantly, you can use test-agent-server to watch the files on the filesystem and execute relevant tests when they change:

1. Run DEBUG=1 make
2. Run make test-agent-server &
3. Run B2G Desktop and open the Test Agent app
4. Edit files and when you save them, glance at the console with test-agent-server running

Note: If you add new files, you will need to restart test-agent-server.

For more details on writing tests, see: https://developer.mozilla.org/en/Mozilla/Boot_to_Gecko/Gaia_Unit_Tests

Integration tests for an app are located in apps/<APP>/test/integration/.

Prerequisites:

1. adb
2. FirefoxOS Device / Emulator / B2G Desktop

To run integration tests:

1. In your gaia/ directory, run make to build the profile

2. Run B2G Desktop

   or forward port 2828 from your device / emulator using adb forward tcp:2828 tcp:2828

3. Run make test-integration from the gaia/ directory

   or make test-integration APP=<APP> to run unit tests for a specified app

   or make test-integration TESTS=<PATH/TO/TESTFILE.js> to run unit tests in a specific file

   or make test-integration REPORTER=<REPORTER> to run integration tests with the specified reporter, for example XUnit

Note: If you're using a FirefoxOS Device, it must have been flashed with a build with marionette enabled. If it doesn't have marionette enabled, then running make test-integration will time out.
