Using testing.T in TestMain
Tag : go , By : Yohan Lee

Hope this helps It sounds like you are looking for a BeforeEach pattern. You don't have access to a testing.T object in TestMain because this is something more of a place to do initialization before and after the test suite runs.
There are a few frameworks out there that can give you a BeforeEach cheap:
type test struct{
  ctrl *gomock.Controller
  mockFoo *MockFoo
  // ...
}

func beforeEach(t *testing.T) test {
  ctrl := gomock.NewController(t)
  return test {
    ctrl:ctrl,
    mockFoo: NewMockFoo(ctrl),
  }
}

func TestBar(t *testing.T) {
  test := beforeEach(t)
  // ...
}

func TestBaz(t *testing.T) {
  test := beforeEach(t)
  // ...
}

To fix the issue you can do TestMain is only executed in test files (suffix _test.go).
Move the function to the repository_test.go file to fix this.

TestMain - no tests to run

I wish this help you Odds are, your problems are around the mode value you're passing to os.Mkdir(...). You're providing 666 decimal, which is 01232 octal (or if you prefer, a permissions string of d-w--wx-wT) which I assume is not really what you're looking for.
Instead of 666, you should specify 0666 -- the leading 0 indicates your value is in octal notation.
package gcc

import (
  "testing"
  "path/filepath"
  "os"
)

const testoutput = "testoutput"

type testcase struct {
  inFile  string
  outFile string
  err     error
}

func (tc *testcase) test(t *testing.T) {
  var (
    in  = filepath.Join("testdata", tc.inFile)
    out = filepath.Join(testoutput, tc.outFile)
  )

  if err := Compile(in, out); err != tc.err {
    t.Errorf("Compile(%q, %q) == %v; Wanted %v", in, out, err, tc.err)
  }
}

func TestCompile(t *testing.T) {
  os.Mkdir(testoutput, 0666)

  tests := map[string]*testcase{
    "correct": &testcase{"correct.c", "correct_out", nil},
    "wrong":   &testcase{"wrong.c", "wrong_out", expectedError},
  }

  for name, tc := range tests {
    t.Run(name, tc.test)
  }
}

fixed the issue. Will look into that further The TestMain function is local to a test package.
func TestMain(m *testing.M)
