Run unit tests

grunt test

Note: This generates test and coverage reports (see the test/reports folder).

Run end-to-end tests locally

grunt e2e-local

Note: Both the point cloud and minimap use a canvas and can't be tested automatically so they must be verified manually using the screenshots in the report (open e2e/reports/report.html in your browser).

Run end-to-end tests remotely on Sauce Labs

Connect to Sauce Labs using the sauce-connect program. Further details on how to install and run this tool can be found here.

Setup Sauce Labs credentials before running the tests.

export SAUCE_USERNAME=<your sauce labs username>
export SAUCE_ACCESS_KEY=<your sauce labs access key>

Run the tests in Google Chrome (Linux).

grunt e2e-sauce

Both the point cloud window and minimap use a canvas, which can't be tested automatically. Therefore, the tests must be verified manually using the screencast in the report at https://saucelabs.com/u/<your sauce labs username>.

Also Travis-CI runs end-to-end tests on Sauce Labs.

Note: Executing grunt e2e-sauce locally will undo all changes in app/ folder.
