Developers, team leads, architects and testers
Testing forms an integral part of the modern software development flow. From customer-facing acceptance tests to code-focused unit tests, automated testing is part of the fabric of a modern build process and deployment pipeline.
In this online course, you will learn about good unit tests (GUTs) and test-driven development (TDD) by seeing what it takes, putting them into practice, and reviewing what you've learned.
But it's not enough that there are some tests: to be a help, not a hindrance, tests need to communicate not just verify, and testing needs to be a development habit, not an afterthought.
What practices support readable and maintainable tests? What test pitfalls hold developers and products back? How do you make testing fun and not a chore? Join us to answer these questions and more.
The examples and hands-on exercises will use Java and JUnit 5, but you don't need to be a Java guru to take part.
