Jasmine is a behavior-driven development (BDD) framework for testing JavaScript code. Jasmine has no external dependencies and does not require a DOM.

Jasmine is a stand-alone behavior-driven development (BDD) framework used for unit testing JavaScript code.

Jasmine tests are broken up into describe and it statements. describe is used to denote the start of a test suite and it is used to denote the start of a particular test. expect statements are then used to outline the conditions under which a test should pass.

beforeEach and afterEach are some other frequently used blocks. beforeEach is used to run some code before each test. Something like loading a module. Similarly afterEach is used to run some code after each test. Running some cleanup code for instance.

Jasmine DOM Testing
