The agile tester (ˈadʒʌɪl/ ˈtɛstə/) is an mammal member of the family “Exploratoris”. He lives in the wild in small groups named cross-functional agile teams.           Skills Besides communication and technical skills, his main traits are curiosity and empathy [1]. Curiosity helps the agile tester in finding opportunities to improve the product. The agile tester questions ...

This post is part of the “Legacy Code to Testable Code” series. In the series we’ll talk about making refactoring steps before writing tests for legacy code, and how they make our life easier. As with renaming, extracting a method helps us understand the code better. If you find it easy to name the method, it makes sense. Otherwise, you ...

This post is part of the “Legacy Code to Testable Code” series. In the series we’ll talk about making refactoring steps before writing tests for legacy code, and how they make our life easier. Renaming is easy and is usually safe. Most IDEs have the functionality, and most languages (I’m not talking about you, C++) lend themselves to safe renaming. ...

Why Another JUnit Tutorial? JUnit seems to be the most popular testing tool for developers within the Java world. So it is no wonder that there have been written some good books about this topic. But I still meet quite often programmers, who at most have a vague understanding of the tool and its proper usage. Hence I had the ...

If you’re writing Java code chances are you’re writing at least a few classes that adhere to the JavaBean conventions, i.e., classes that have private properties with public getter and setter methods, contain a no-arguments constructor, are serializable, and comply with the Equals and HashCode contract. And on top of that you’ll probably also throw in a useful toString() implementation. ...

Hi there! Today i’m gonna show you how to create and run junit tests inside your android project without creating a separated test project. With those tests we will rapidly be able to automate and test the app’s logic and some simple UI behaviors. The example below is very straightforward and much more intuitive than other approaches i saw out ...

It’s been 10 years since I wrote my first unit test. Since then, I can’t remember how many thousands of unit tests I’ve written. To be honest I don’t make any distinction between source code and test code. For me it’s the same thing. Test code is part of the source code. The last 3-4 years, I’ve worked with several development ...

Property based testing is an alternative approach to testing, complementing example based testing. The latter is what we’ve been doing all our lives: exercising production code against “examples” – inputs we think are representative. Picking these examples is an art on its own: “ordinary” inputs, edge cases, malformed inputs, etc. But why are we limiting ourselves to just few examples? ...

Load-testing is not trivial. It’s often not just about downloading JMeter or Gatling, recording some scenarios and then running them. Well, it might be just that, but you are lucky if it is. And what may sound like “Captain Obvious speaking”, it’s good to be reminded of some things that can potentially waste time. So, when you run the tests, ...
