Jasmine-intercept NPM

DEPRECATION NOTICE 7 JAN 2014

jasmine-intercept has been superseded by where.js

jasmine-intercept

Provides an intercept() method for the Jasmine BDD test framework, in order to capture expected failures and report them as passed to the jasmine reporter, mainly as a shield for continuous integration environments.

Thanks to:

Jamon Holmgren (@jamonholmgren) for your feedback regarding this API.

justify

tl;dr ~ needed this while using jasmine to test-drive my jasmine-where repo.

npm

npm install jasmine-intercept

git clone https://github.com/dfkaye/jasmine-intercept.git

important

Including or requiring jasmine-intercept adds an intercept() method to the global environment, for example:

require('jasmine-intercept');

intercept === global.intercept === jasmine.getEnv().intercept;

<script -- jasmine 1 or 2 scripts first -->
<script src="../jasmine-intercept.js"></script>

intercept === window.intercept === jasmine.getEnv().intercept;

use

intercept takes a function with a body of expectations and returns a results object containing arrays of failing and passing messages generated by the spec runner.

Use var messages = intercept(function () { // body of spec }) to capture expected failures in order to prevent them appearing as failed in the jasmine reporter.

Inspect the returned messages.failing and messages.passing arrays for length and content.

examples

Use in an it-eration:

it('should intercept messages', function () {
      
  var messages = intercept(function() {
    expect(1).toBe(1);
    expect(typeof drink).toBe('mixed'); // should be 'undefined'
  });
  
  expect(messages.failing.length).toBe(1);
  expect(messages.failing[0]).toBe("Expected 'undefined' to be 'mixed'.");
  expect(messages.passing.length).toBe(1);
});

Use in asynchronous it-eration:

it('should intercept asynchronous messages', function (done) { // <= pass done here

  setTimeout(function () {
  
    var messages = intercept(function() {
      expect(1).toBe(1);
      expect(typeof drink).toBe('mixed'); // should be 'undefined'
    });
    
    expect(messages.failing.length).toBe(1);
    expect(messages.failing[0]).toBe("Expected 'undefined' to be 'mixed'.");
    expect(messages.passing.length).toBe(1);
    
    done(); // <= call done here
    
  }, 500);
  
});

jasmine versions supported

Current implementation runs in both jasmine 1.3.1 and jasmine 2.0.0-rc3.

Using jasmine-node which uses jasmine 1.3.1 internally.

jasmine-node --verbose ./test/suite.spec.js

or simply

npm test

rawgit test page

The jasmine2 browser test page is viewable on rawgit.

testem

Using testemjs to drive tests in multiple browsers for jasmine-2.0.0 (see how to hack testem for jasmine 2), as well as jasmine-node. The following command uses a custom launcher for jasmine-node in testem:
