Join Kit Eason for an in-depth discussion in this video Exercise solution: Converting tests to use Expecto, part of F#: Automated Testing for Developers.
- [Instructor] Hopefully, that exercise…didn't give you too much trouble.…You just need to copy across the code from the test here…into your program.fs,…inside of the let binding site yield testProp,…and change this to a label to the function name.…At the end, make sure you've got the backwards pipe.…Then, to clear the body of the test is a lambda function,…with the same arguments as before.…Then, this code here has just been indented slightly…to make it's fully inside the lambda.…
And then, the only other change I had to make…was to take out these unquote operators.…Replace them with equals comparisons…and and them together,…and that should work just fine.…

6/15/2017Kit Eason explains how to use xUnit—a .NET unit-testing package—to do some test-driven development, and demonstrates how to improve your test run experience using NCrunch, a test runner. He shows how to use FsCheck to generate test cases, and how to use Expecto to move into the world of tests as first-class values. He also covers the use of Canopy to automate the testing of web user interfaces, and of mocking to tame dependencies.
