Hi. Specs2 is one of the most popular Scala libraries for testing, but definitely not a simple one. That’s why I decided to create a blog post with a few tricks how to make working with Specs2 much easier. The examples are 100% artificial, but their purpose is only to demonstrate capabilities of Specs2.
Ok, so let’s start with a basic example
We can do this in (at least) two ways. Just pass the data as regular variables
or pass them as a scope
The first option is very straightforward and works well for small tests, but is impractical for bigger ones or when you want to (for some reason) share the values.
Now let’s say that we need to perform some important operations before and after every single test case. How can we achieve that? It’s simple. We can use Contexts again.
First we need to create an helper for local setup and Teardown. We can do it like this
now we can do
The example above works good but only for single test cases, now lets write something for the whole test suite.
