The more complex an application becomes, the greater is the benefit of Docker. If everything runs in containers, we can use a tool like docker-compose and start all the parts with one single command. No need to install all the tools, services, and frameworks – just run docker-compose and the magic happens automatically. We can …
As we saw last week, parametrised tests help us to reduce the number of test methods we have to write and still keep the coverage high. However, writing the test parameters multiple times is error prone, especially when it is important that we test all values. Let us look on how NUnit can help us …
Parametrised tests help you to create many test cases without writing a lot of test methods. This approach saves you a lot of time and increases the quality of your tests. Let us look how we can parametrise our tests in NUnit. The [TestCase] attribute A parametrised test in NUnit needs the [TestCase] attribute, …
Last week I attended the “Make Your Code More Testable” workshop by Ted M. Young (@jitterted). I was not sure if I wanted to attend yet another workshop this year as I saw the first tweet about this workshop. After I saw the recommendations by Gitte Klitgaard, Esther Derby, Kent Beck and GeePaw Hill I …
Parametrised tests are a great help to create many test cases without the need to write many tests. Let us look how they work in pytest. This post is part of my journey to learn Python. You can find the other parts of this series here. FizzBuzz I like the FizzBuzz kata for its …
Code katas are little exercises that help you to improve your programming skills. My favourite one is the Gilded Rose kata. It was originally created by Terry Hughes and is now maintained by Emily Bache (@emilybache). While most katas start from scratch, the Gilded Rose kata comes with existing code that you need to modify. …
The bigger our test suite gets, the longer it takes to run all tests. With markers we get a nice way to tell pytest which test it should run and which not. This post is part of my journey to learn Python. You can find the other parts of this series here. What markers …
While built-in fixtures are a great help, they cannot address the specific needs of our applications. It is now time to have a closer look on how to create our own fixtures. This post is part of my journey to learn Python. You can find the other parts of this series here. Why not …
Fixtures are a powerful feature in pytest. You can write your own fixtures as a replacement for setup and teardown methods or use the built-in ones to access common functionality. This post has a closer look to the fixtures that come directly with pytest and shows you how to use them. This post is part …
I prefer code that throws an exception as soon as it detects an unrecoverable situation. This is annoying but a lot less troublesome as when those errors go unnoticed to production. How can we test if our code throws the expected exceptions? This post is part of my journey to learn Python. You can find …
