Side-by-side diffing for Jasmine string comparisons.

jasmine-visual-diff

Side-by-side diffing for Jasmine string comparisons.

Quick hack leaning on https://github.com/wickedest/Mergely and its dependencies (Code Mirror, jQuery).

Installation

• Grab the source with a git clone https://github.com/deanhunt/jasmine-visual-diff.git
• Visit chrome://extensions; navigate to the repo and load its entire folder (including manifest.json).
• Check "Enable in Incognito Mode" if it pleases you.

Use

• Run your Jasmine tests via SpecRunner.html.
• Click the Expected 'something' to be 'something else' error reported in Jasmine test failures (not the stack trace).
• The inline string comparison will be replaced by a side-by-side diff. (The stack trace will also be compressed.)

Limitations

• Only works on URLs container the text SpecRunner
• Only currently recognizes the form "Expected 'something' to be 'something else'"
• Mergely has a viral license so it's not embeddable directly within application code (thus the extension)
