Package Exports

jasmine-es6-promise-matchers

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (jasmine-es6-promise-matchers) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

...or...

Documentation

Testing promises should be simple. This library aims to make it so!

Initializing the library

To use it, just install the library before your tests begin:

beforeEach(function() {
  // `true` automatically ticks the Jasmine mock-clock for you after each assert.
  // `false` leaves the clock management up to you.
  // I recommend `true` unless your test involves other timing concerns.
  JasminePromisMatchers.install(true);
});

And uninstall it once your tests are over:

afterEach(function() {
  JasminePromisMatchers.uninstall();
});

Now you're ready to start testing!
