Cucumber scenario as go subtest

[lburgazzoli]

To make godog better integrated with the go testing framework, I wrote a test method that translate each feature into a subtest and each scenario in another subtest:

func TestFeatures(t *testing.T) {
	g := gomega.NewWithT(t)

	for i := range opts.Paths {
		root := opts.Paths[i]

		err := filepath.Walk(root, func(p string, info os.FileInfo, err error) error {
			g.Expect(err).To(gomega.BeNil())

			if info.IsDir() {
				return nil
			}

			name := filepath.Base(info.Name())
			ext := filepath.Ext(info.Name())

			if ext != ".feature" {
				return nil
			}

			testName := strings.TrimSuffix(name, ext)
			testName = strings.ReplaceAll(testName, "-", "_")

			t.Run(testName, func(t *testing.T) {
				o := opts
				o.TestingT = t
				o.Paths = []string{path.Join(root, info.Name())}

				status := godog.TestSuite{
					Name:                "foo",
					Options:             &o,
				}.Run()

				g.Expect(status).To(gomega.Equal(0))
			})

			return nil
		})

		g.Expect(err).To(gomega.BeNil())
	}
}

Maybe, such method could be added to the godog.TestSuite framework with something like:

package godog

func RunUnfolded(t *testing.T) err {
    ...
}

And consumed like

func TestFeatures(t *testing.T) {
    status := godog.TestSuite{
        Name:                "foo",
       Options:             &o,
    }.RunUnfolded(t)
}
