Jasmine is a popular framework used to test JavaScript and Angular applications. With the help of Jasmine, writing effective unit tests is quite easy and helps in building more reliable applications. 

The purpose of this course is to teach you how to read and write Jasmine unit tests. This course will focus on Angular test skills, including the ability to mock HTTP requests and test forms. Moreover, you will learn how to build real-world applications using Jasmine’s advanced features.

As a result of completing this course, you will be able to read existing unit tests, write your own tests, and be able to write better applications and the skills to maintain them for years to come.

Angular Testing with Jasmine

Suppose we are testing a complex feature. We might need to run a series of steps and make expectations along the way to be sure everything is working correctly. If in the future, one of the tests fails, it will show a generic error message. However, it can still take some time to work out exactly which expectation has failed.

In order to improve the error messaging for failing tests, we could consider a few approaches:

- Where it makes sense, split large tests with many expectations into smaller tests. If one of the tests fails, we are able to pinpoint the source of the error more easily.

- We can chain the `withContext` method onto an expectation in order to add some context that would help explain why the expectation has failed.

- We could make use of a custom matcher, which lets us specify our own error messages. These are useful when we are making expectations about complex data types, such as strings or objects.
