Protractor provides the capability to disable test cases, i.e it-blocks. This function is used to organize your tests into suites. Jasmine is a behavior-driven development testing framework, which allows you to define test suites through one or more nested describe functions. With similarities to rspec, I’ve quickly grown attached to this framework and have been looking for opportunities to discuss it. Jasmine provides the functionality to the user, that one can execute specific test cases or test suites. Nested describe blocks. I want to go full out TDD on it so I started with a feature file, now I’m … Issue #1508 , toEqual and jasmine.objectContaining fail to recognize equal objects with functions Expected Behavior I would expect this text assertion to Currently, I have a function that sometimes return an object with some functions inside.

It contains two other blocks, one is “Describe ()” and another one is “It ()”. However, from a learning point of view, it’s probably easier to grasp testing concepts when we first explore the APIs we want to test. The above two examples use the #toEqual matcher. It is chained with a Matcher function, which takes the expected value. xdescribe). The describe function is for grouping related specs. Typically, a describe-block contains one or more it-blocks. These functions can be used to speed up test suites with expensive setup and teardown. One way to do this is to temporarily comment out tests that you don’t want to execute.
