How to work with Test Tables and Mocks in Go

For this example we will use 2 external packages:

-gomock -testify/assert

Mocks

For the mocks I use gomock. It is a mock framework for Go. It integrates well with Go's built-in testing package, but can be used in other contexts too.

You can see in the file generate-mocks.sh how to generate the mocks.

Test Tables

For the test tables I use a map[string]struct{} with the key being the name of the test and the value being a struct{}.

Inside of the struct we add all the external information we will need like parameters.

We also add there 2 functions:

• testSetup: This function will be called before the test is run. It will setup the behavior of the mocks and the test data.

• assertSetup: This function will be called before the test is run. It will setup the mocks and the test data.
