PM: You know, you could have something built by now. You do call this series “integration testing with Spring TDD” or something. Me: Yeah, and I would probably build something you did not want. Just a few more cases. Remember, Read more…
Product Manager: Man, you still haven’t touched your keyboard? I haven’t seen you doing any Spring or TDD or anything technical yet. Are we going anywhere with this? Me: Of course! It’s calculation time! That’s what you wanted, right? Let’s Read more…
So many TDD cases, so many posts. And no Spring in sight yet. I promise, we’ll get there. For now, let’s continue to explore the requirements. Where did we last stop? Pressing any digit key, the display adds that digit Read more…
It is customary to think that in TDD we run ahead and just write tests. Not today, Spring will have to wait. Let’s break down the requirement into test cases, so we can understand them better. Buckle your seat belts, Read more…
Most TDD examples start out with a calculator. Ours will start here as well. But we’re not going to write a test for “2+2”. No sir, we’re going to test drive the calculator display. But what does it actually do? Read more…
I’ve been working with teams who use Spring as the basis of their programming for some time now. Spring, many times as a microservices development and runtime framework. Luckily (or not) they want to incorporate TDD (Test driven development) into Read more…
Now that we’ve covered some of Spring capabilities, we can explore possibilities beyond simple mocking. Instead of “regular” mocks (that we can set up in the integration tests), we can inject actual simulators. For our purpose, let’s define a simulator Read more…
Here’s the situation: We have a couple of configuration files we use for integration tests. Each of them is a different set of real and mock objects. Some of the objects have behaviors set on them (using Mockito.when) in the Read more…
Last time, in the first post in my new clean code series, we discussed how I torment my students with the ol’ Square and Rectangle trick in my Clean Code course, talking about Liskov Substitution Principle (LSP). At the end Read more…
