Thank you, Travis!
Tests structure and test structure — are very important things.
Tests structure (I wrote a raw article on this back in 2017) helps you understand test coverage and pick up tests in test plan. There are different techniques for that and as to me — it is a test cases management tool business to help you with this. This year I am going to write a new article (a chapter in a book) on this topic to develop it more. As to me Google Translate (in-Chrome browser “translate this page to English”) translates my simple Russian language into simple English pretty well — so you’ll see it.
As to test structure (single unit) — it helps you to get all the necessary info to check what is required and how and why. These are conceptual, strategic questions to answer beforehand. I also wrote an bunch of articles on this that together might put some light on that question for you:
Anyway, every team and every company for some term of their existence chooses some structure of tests and of a test that helps them to do what they do better (jobs to be done article). As soon as they understand what test cases are for them, the sooner they’ll outline what is the best test case for them. How it looks like? What it contains and when and why and how? And then they can figure out how to write different kinds of tests with and without steps that would fit their aim and purpose and their way.
And my aim as a writer — is just to help them to ask and answer those questions to themselves.
I hope it helps!
Best regards, Travis!
