Writing Specs

This feature allows you to write test cases (specs) within a suite. A suite begins with a call to the global Jasmine function 'describe' with two parameters: the title of the suite and a function containing one or more specs.

describe('A suite', function() {\n  it('contains spec with an expectation', function() {\n    expect(true).toBe(true);\n  });\n});

Setup and Teardown

This feature allows you to define code that will run before and after each spec in a suite. 'beforeEach' and 'afterEach' are used to set up preconditions and clean up after your specs.

describe('A suite', function() {\n  beforeEach(function() {\n    // Code to execute before each spec in this suite\n  });\n  afterEach(function() {\n    // Code to execute after each spec in this suite\n  });\n});

Asynchronous Support

This feature supports asynchronous tests, which are crucial for handling AJAX, timeouts, or any operations that rely on external systems. The 'done' callback is used to tell Jasmine when the asynchronous function has completed.

describe('Async spec', function() {\n  it('supports async execution of test preparation and expectations', function(done) {\n    setTimeout(function() {\n      expect(true).toBe(true);\n      done();\n    }, 1000);\n  });\n});
