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 configuration classes. Now, one of the integration tests need one 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 of the discussion, we got the audience to understand the Read more…
In my Clean Code class, I go through this example about the Liskov Substitution Principle (LSP), part of the SOLID material. This example, the rectangle and the square, never fails to stump people, both experienced and less so. It starts out with the question: Is a square a rectangle? Which of Read more…
After we understand how to use mocks in Spring in integration tests, let’s take a look at a setup for testing a REST service that uses a dependency we want to mock. API testing is a usual integration test scenario, and with those, we might need to mock dependencies buried Read more…
Let’s continue where we’ve left off – multiple configurations for integration tests. We use different configurations when we need to inject two different sets of objects. For example a real one and mocked one of the same type for different integration test purposes. Let’s say we have a REST API Read more…
First, a couple of words about Spring in general as a dependency injection framework. One of the best things in Spring is its simplicity of injection. Regardless of where you are, you pop an @Autowired annotation on a class variable (which could be the test class), and it’s ready for injection. Read more…
He said: “I asked all my friends, and none of them likes TDD”. This one I haven’t heard before, although I suspect I should have at some point. Like any practice, TDD has a social side. I told him to find new friends, which he conveniently ignored. He then continued: Read more…
So far, we’ve talked about the process itself, our goals and expectations, what to look for while we’re moving forward, and now it’s time we get to the good stuff. How does an implementation plan actually look like? A good plan includes these elements: Training Remember that when we start, we Read more…
We talked about management attention and support, and there’s more leaders can do, in order to help us make the process work. Remember those leading indicators? They don’t collect themselves. If we think about those indicators as a feature, there are customers waiting for them.. Management and leaders are those Read more…
