This course explores the different features available in Mocha such as before and after hooks, asynchronous operations using promises and async/await, configuring different Mocha reporters, and running Mocha on the browser.

Unit Testing in JavaScript: Mocha & Chai

Unit Testing in JavaScript: Mocha & Chai

• discover the key concepts covered in this course
• install the Chai library on your local machine
• use assertions to test boolean values
• compare numeric values using assert
• performing string comparisons using assert
• describe the assertions that can be used to test objects and their properties
• use arrays and elements in arrays using assert
• compare and contrast the should and expect APIs in Chai
• test different data types using should
• test different data types using expect
• perform asynchronous function testing using expect
• summarize the key concepts covered in this course

This course gets you started with the Chai assertion framework and the assert, should, and expect APIs in Chai for test-driven development and behavior-driven development. You will use the classic assertion API as well as the Should and Expect API in Chai to test numbers, booleans, strings, objects and object properties, and arrays in Chai.

• use assertions to test function objects
• work with arrays and array elements
• compare objects using equality operations
• test objects using match
• determine whether objects are instances of other objects
• summarize the different ways to test errors
• describe how values of different data types can be tested
• summarize the key concepts covered in this course

This course uses the Mocha testing framework and the Unit.js assertion library to unit test your JavaScript code. You will write unit tests to test numeric values, strings, objects, arrays, functions and exceptions using Unit.js.

Unit Testing in JavaScript: Should.js & Must.js

Unit Testing in JavaScript: Should.js & Must.js

• discover the key concepts covered in this course
• recall the different styles that can be used with the Should.js API
• describe how different data types can be tested using Should.js
