karma-jasmine-bridge.js

What is it ?

This plugins allows to add support of APIs from Jasmine 1 into Jasmine 2 or Jasmine 3 environment.

List of API supported:

• runs
• waitsFor
• waits
• Spy API :
  • spy.andCallThrough();
  • spy.andCallFake(function() {});
  • spy.andThrow('error');
  • spy.andReturn(1);
  • spy.reset()
  • spy.callCount
  • spy.mostRecentCall.args
  • spy.calls[0].args
  • spy.argsForCall[0]
• Clock API:
  • useMock()
  • tick()
• CustomMatcher API

Why ?

Because legacy applications which have a lot of tests with Jasmine need to be moved slowly when developers remove technical debt.

So with this plugin you can run your legacy tests (Jasmine1) on a Jasmine2 environmment without change anything (almost :)) and when you get ready you can modify your unit tests little by little by making a migration on Jasmine 2 API.

How to install ?

npm install karma-jasmine-bridge

Adds this in your karma-conf.js

frameworks: ['jasmine-bridge', 'jasmine'],

the order matters because bridge wraps jasmine features so plugin must be loaded before jasmine. Here, of course it's about a jasmine 2 or 3 env.

Tests
