Creating subtests

In some cases, it is useful to create a set of tests that could have a similar setup or clean-up code. This could be done without having a separate function for each test.

How to do it...

1. Open the console and create the folder chapter11/recipe04.
2. Navigate to the directory.
3. Create the file sample_test.go with the following content:

        package main

        import (
          "fmt"
          "strconv"
          "testing"
        )

        var testData = []int{10, 11, 017}

        func TestSampleOne(t *testing.T) {
          expected := "10"
          for _, val := range testData {
            tc := val
            t.Run(fmt.Sprintf("input = %d", tc), func(t *testing.T) {
              if expected != strconv.Itoa(tc) {
                t.Fail()
              }
            })
          }
        }

4. Execute the tests by go test -v.
5. See the output in the Terminal:

How it works...

The T struct of the testing package also provides the Run method that could be used to run the nested...
