ATDD, Generating random tests with ScalaCheck

Reading Time: 3 minutes Further, in our series on Acceptance Test Driven Development, we would look at generating random test values with the ScalaCheck framework. In our last post we looked at, how we make our test logic respect the DRY principle by defining the values in a table. However, in many situations, you would like to generate the values dynamically so that we do not have to fill Continue Reading

ATDD, ScalaTest, Cucumber and respecting DRY

Reading Time: 3 minutes In our last post we looked at how it was easy to use ScalaTest for doing acceptance testing. In a post prior to that, we had looked at doing the same with Cucumber. We had also concluded that though acceptance tests could be written in the way described however, there was an issue. Writing the feature files with individual features having multiple scenarios which would Continue Reading

ATDD, ScalaTest and Scala

Reading Time: 3 minutes In my last post on ATDD, we had seen how it was easy with Cucumber to write a feature file and share it with our stakeholders in order to validate our understanding of the functionality. The idea again is to build the right software right. In this post, we would learn how to do ATDD with ScalaTest but before that let us do a recap Continue Reading
