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

• qHD: ~540×960, device pixel ratio = 1.6875
• WVGA: ~480×800, device pixel ratio = 1.5

You need to set HIDPI=1 when using any make command

HIDPI=1 make reset-gaia HIDPI=1 make install-gaia HIDPI=1 BUILD_APP_NAME=contacts make install-gaia

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

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

   or make test-integration TESTVARS=<PATH/TO/TESTVARS.json> to run tests with variables in the testvars file (this defaults to testvars.json)

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.

The testvars file is a JSON file that maps app names to objects holding key/values as required by that app's integration tests. See that app's integration test code and/or README for which key/values are required.
