Jasmine-Matchers

npm install jasmine-expect --save-dev

If you have some useful matchers of your own, please add them via Pull Request.

The Jasmine testing framework from Pivotal Labs comes with this default set of matchers;

expect(fn).toThrow(e);
expect(instance).toBe(instance);
expect(mixed).toBeDefined();
expect(mixed).toBeFalsy();
expect(number).toBeGreaterThan(number);
expect(number).toBeLessThan(number);
expect(mixed).toBeNull();
expect(mixed).toBeTruthy();
expect(mixed).toBeUndefined();
expect(array).toContain(member);
expect(string).toContain(substring);
expect(mixed).toEqual(mixed);
expect(mixed).toMatch(pattern);

All Jasmine-Matchers does is add a few more;
