End-to-end test automation is an important part of the development lifecycle of any web based application. Choosing the right tool for you and for your application is arguably even more important. In this guide, we'll take a look at end-to-end testing using Cypress. "End-to-end" testing refers to the...

Test "mocks" are objects that replace real objects while simulating their functions. A mock also has expectations about how the functions being tested will be used. In some unit test cases we may want to combine the functionality of spies, to observe a method's behavior under call, and...
In software testing, a "spy" records how a function is used when it is tested. This includes how many times it was called, whether it was called with the correct arguments, and what was returned. While tests are primarily used to validate the output of a function, sometimes...
Testing is a fundamental part of the software development process. When creating web applications, we make calls to third-party APIs, databases, or other services in our environment. Therefore, our tests must validate those request are sent and responses handled correctly. However, we may not always be able to communicate with...
