Notes from Go with Tests
Raw
go-with-tests.md
  • Write the test first -> Try and run the test -> Write the minimal amount of code for the test to run and check the failing test output -> Write enough code to make it pass -> Refactor
  • We must not neglect our test code in the refactoring stage
  • It is important to question the value of your tests. It should not be a goal to have as many tests as possible, but rather to have as much confidence as possible in your code base. Having too many tests can turn in to a real problem and it just adds more overhead in maintenance. Every test has a cost.
  • reflect.DeepEqual - useful for seeing if any two variables are the same. Caveat: It is not type safe. Compiles even if silly comparisons like array == string is done. https://golang.org/pkg/reflect/#DeepEqual
