Free online courseJasmine Testing Framework Course

Course Description

Learn how to write reliable unit tests for JavaScript applications with this free Jasmine testing course in the Technology and Programming category, focused on software testing. You will start by understanding why Jasmine is a popular choice for unit testing and how its core concepts help you validate behavior with clear, readable specs.

Through a practical calculator project, you will connect real UI input handling to testable logic, work with DOM updates, and improve error handling so your app behaves predictably in edge cases. You will then set up Jasmine properly and follow common naming conventions while organizing suites and specs in a maintainable way.

The course guides you through expectations and matchers in depth, including equality checks, truthy and falsy conditions, null and undefined handling, containment checks, NaN validation, regex matching, and error assertions. You will also explore asymmetric and custom matchers to handle flexible assertions and create reusable testing patterns.

As you progress, you will structure tests with nested suites, apply setup and teardown lifecycle hooks, and use shared context effectively. You will gain hands-on experience with spies and test doubles, covering function spying, stubbing behavior, call tracking, argument checks, prototype spying, and advanced spy configurations such as callThrough, callFake, return values, and throwing errors.

Finally, you will test asynchronous JavaScript with promises, done callbacks, and async await, while learning how to mock network calls to keep tests fast and deterministic. You will also automate test execution with a runner setup, add headless browser support, and generate coverage reports to measure what your tests truly verify.
