Chapter 9. Testing in F#
Enthusiasts of typed functional languages tend to say that the only errors you need to care about are compilation errors. That would indeed be the ideal situation, but even a compiler as advanced as F#'s cannot detect all errors; it is still necessary to test your code. For many years now, programmers have learned to automate these tests to avoid the time-consuming process of manual testing. There are many great tools for automated testing for all popular languages, and F# is no exception. In this chapter, we will overview several techniques from the widely used unit tests to the more advanced property-based testing.
In this chapter, we will cover the following topics:
- How to write unit tests in F# with the popular NUnit tool, and the advantages the language offers for this. We will also see how to easily run tests in our builds with FAKE to make sure we haven't introduced regression bugs with our changes.
- Property-based testing with FsCheck is a more robust way to...
