Write Negative API Tests


So far we have written all the positive/happy path test scenarios, in this post, we’ll take a look at how we can write a few negative API tests to ensure our APIs are secure and functioning as they should.

Let’s take a look at some examples -

Unauthenticated Test
Create a test to ensure the user cannot hit the APIs without being properly authenticated.

Validation Failed
Create a test to ensure the user should not be able to create data without passing in the required fields.

Check out this video to see how to implement the above test scenarios:
