Writing Jasmine specs for asynchronous operations using the done() function

To test JavaScript's asynchronous functions/calls is a challenge. However, Jasmine 2.x provides a good way to test functions that are called asynchronously. In this recipe, you will learn to develop Jasmine specs for asynchronous operations using the done() function.

To understand this recipe, let's assume that you are developing an application using JavaScript and you have to design specs for asynchronous operations.

"As a JavaScript developer, I want to create Jasmine specs for asynchronous operations so that I can implement a test condition successfully."

Let's consider the following scenario in the current context:

  • Scenario-1: Jasmine should support JavaScript asynchronous operations using the done() function

How to do it…

To design specs for asynchronous operations, you need to perform the following steps:

  1. Create the asynchronous_with_done_spec.js file under the /spec folder and code the following lines:
