I am trying to create a new module called myrepo to learn how to extend gitea. I wanted to start off with a test:

// modules/myrepo/create_test.go

package myrepo

import (
	"testing"

	"code.gitea.io/gitea/models"

	"github.com/stretchr/testify/assert"
)

func TestMyRepo(t *testing.T) {
	// this is fine
	assert.Equal(t, 1, 1)
	// this gives the segmentation violation
	assert.NoError(t, models.PrepareTestDatabase())
}

I do:

go test  -mod=vendor -tags='sqlite sqlite_unlock_notify' code.gitea.io/gitea/modules/myrepo

The error:

--- FAIL: TestMyRepo (0.00s)
panic: runtime error: invalid memory address or nil pointer dereference [recovered]
	panic: runtime error: invalid memory address or nil pointer dereference

Any idea why this happens? (If it's better to pose dev questions like this on the forum, let me know.)

I found out I need to add this to modules/myrepo/create_test.go:

import (
	"path/filepath"
      // ...
)

func TestMain(m *testing.M) {
	models.MainTest(m, filepath.Join("..", ".."))
}
