[Exactly Anthony Fung, it already falls in frontend cases in specific situations where it was necessary to perform two actions. In most cases this was not necessary. When I began to apply a critical eye more frequently to unit tests, I began to observe that the more actions in a single test method, the more easily it broke.](https://hashnode.com/posts/keeping-tests-valuable-avoid-problems-in-the-act-blocks/6404ee122504533242704d70/comment/6410f0f0d0ccf16ed81830b0#reply-641296650dd7cb923f69468d)

[Anthony Fung Nice, I think it's important to have this view you commented, in the last year I have adopted a more simplistic testing strategy, look at the requirement, understand the expected behaviors and just check what really matters in the assert. I also look for invalid scenarios, unusual inputs that I wouldn't normally think of if I just did the happy path of unit testing. Obviously this is not always easy to apply, especially in complex systems. I am writing about this as well. What strategy do you usually put into practice for your test cases?](https://hashnode.com/posts/keeping-tests-valuable-using-branching-coverage-to-improve-software-quality/640e830987c97760def75647/comment/6410ee16d0ccf16ed8183076#reply-6411290ed0ccf16ed8183520)
