How do you test a Redux component?

Testing a Redux component involves testing both the component's behavior and its interactions with the Redux store. There are many different types of app testing, but automated unit and integration tests are at the top of the list. It's also important to get all the available information on the form that should be tested and its related conditions beforehand.

Why is it important to test Redux forms?

When it comes to testing, forms require special attention, as forms are an essential part of many projects and a way to communicate with customers. Which is why it’s vital to be properly prepared and carefully go through all the stages – imports, mocks preparation, store creation, form decoration with Redux, and correct wrapper creation.

Which is more suitable for integration and functional testing?

Depending on the type of testing, I use different processes to test forms connected with Redux. For unit tests, I use shallow rendering (as opposed to deep tree rendering) and the Redux-mock-store library. For integration tests, I use mount rendering (deep tree rendering) and an actual Redux store.

What is the difference between unit testing and integration testing?

Unit testing is focused on testing individual units of code or modules in isolation, while integration testing is focused on testing how several modules work together. Both testing types are important for ensuring the reliability and stability of a software application and are usually used in combination to provide a comprehensive testing strategy.

Which is better unit testing or integration testing for web development?

Both unit and integration testing are essential for web development and should be used in combination to provide a comprehensive testing strategy. Unit testing is helpful for catching bugs early in the development process and for ensuring that individual units of code are working as expected. Integration testing, on the other hand, is important for catching integration bugs and for ensuring that the entire application is working as expected in a production-like environment.
