Custom Jasmine 2.x matchers for seeing a more useful output when comparing Strings.

For example you may want to compare files, seeing the output from expect(expected).toBe(result) only outputs the entire comparison with no hint to any deletions, additions and what is the same.

Using the diff the result of the diff matchers will be colored like your regular vcs tooling.

Examples

See the examples in the ./example/* folder. Using the matchers requires you to add them using the Jasmine addMatchers() api in a beforeEach block, Example.

    beforeEach(function () {
        jasmine.addMatchers(require('jasmine-diff-matchers').diffChars);
    });

Now the custom matchers are added to the Jasmine api just like any other core matcher:

    it('should display the same quote from Carl Sagan.', function () {
        expect('pale blue dot').diffChars('pale yellow dot');
    });

You can change the default deletionsColor, addedColor and sameColor with the config:

    require('../config').addedColor = 'blue';
