Throughout all the previous chapters, we have done a great job implementing a series of patterns in our application, the news portal. Now, it is time to understand and validate whether the project business flows are working properly.

Even though it is not a very large microservices project, performing manual tests would be complex and we would surely fail in our evaluation or forget some important tasks for the business of the application.

There is no doubt that automated testing is best suited for any type of software. In this chapter, we will cover the following topics:

• Unit tests
• Integration tests
• End-to-end tests
• Pipelines
• Signature tests
• Monkey tests
