The Path to Approval Testing

You are undoubtedly doing some form of Approval testing already. The most basic form would be writing REQUIRE(42 == 6 * 9), then running it, getting the result 42 != 54 and then changing the code to say REQUIRE(54 == 6 * 9).

This is the path that we commonly see, as people move in to Approval Tests:

• Verify numbers

  • Have lots of numbers, like an array

• Strings - turn the array of numbers in to a string

  • Those strings become long

• Files - Golden Master

  • Managing them - coming up with names

• Some sort of naming convention

• Can be hard to understand what’s in the files

  • Start using diff tools

• Start creating custom methods for the things you are testing

  • verifyThing
