Testing
Testing is a crucial part of being an iOS developer. It ensures our codebase’s quality and reliability and improves levels of confidence in our projects.
Questions about testing in interviews are much more than just technical. Writing a unit test is an easy task and can be learned quickly. But experience in testing shows a different side of us as iOS developers. It offers our approach to managing a reliable and healthy code base.
Answer the following questions:
- Do we write tests after a bug fix?
- How simple is it to test our code?
- What is the test role in the deployment process?
Being a professional doesn’t mean just writing good code but also maintaining it well.
Unlike most topics in this book, it is difficult to gain knowledge of testing without having some experience. I advise you to take one of your projects and write some tests. You need to feel it with your fingers before you approach the interview.
