Learn how to create true Java unit tests by mocking all external dependencies in your unit tests with the Spock testing framework.
Testing applications has become a standard skill set required for any competent developer today. The Python community embraces testing, and even the Python standard library has good inbuilt tools to support testing. In the larger Python ecosystem, there are a lot of testing tools. Pytest stands out among them due to its ease of use […]
Mocking and stubbing are the cornerstones of having quick and simple unit tests. Mocks are useful if you have a dependency on an external system, file reading takes too long, the database connection is unreliable, or if you don’t want to send an email after every test. Unlike with integration or functional tests, where the […]
