Extension Developers: tip for unit testing with turbine

Community Advisor
Community Advisor

This tip is for extension developers (most likely applicable for web extensions only, since I haven't tried this with mobile extensions).

TL;DR create a "global.turbine" variable to mock the turbine free variable, before running your unit tests.

I use jasmine ( for testing my extension. One difficulty that I had was figuring out how to test the "turbine" free variable (

After numerous trials-and-errors, I finally stumbled on this solution:

describe("description of the test suite", function() {
  // create the turbine free variable with "logger"
  global.turbine = {
    logger: jasmine.createSpyObj('', ['debug', 'info', 'warn', 'alert', 'error']),

  // rest of test suite

  it("description of unit test that logs to the logger", function() {
    // run the test

Hope this works for you too!
