Better Failures
Explore advanced Jasmine testing techniques to improve failure messages in your Angular tests. Learn to use withContext for custom error details and create custom matchers for complex validations. This lesson helps you write clearer, more maintainable unit tests by pinpointing the source of failures effectively.
We'll cover the following...
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 ...
