Race conditions when using github.com/Kong/go-pdk/test

[stefan-knowles]

Unfortunately i intermittently get the following error when running tests
panic: Fail in goroutine after TestRejectsRequestWithEmptyToken has completed

// main.go
// [...]
type requestContext struct {
	kong      *pdk.PDK
	startTime time.Time
}

func (conf *Config) Access(kong *pdk.PDK) {
	tokenString, err := kong.Request.GetHeader("Authorization")
	if err != nil {
		conf.setExitStatus(requestCtx, 401, "Error reading 'Authorization' header", "error", err)
		return
	}
	if tokenString == "" {
		conf.setExitStatus(requestCtx, 401, "Invalid 'Authorization' header")
		return
	}
}

func (conf *Config) setExitStatus(ctx *requestContext, status int, msg string, msgArgs ...any) {
	slog.Error(msg, msgArgs...)
	slog.Info("Request complete", "elapseTime", time.Now().Sub(ctx.startTime))
	ctx.kong.Response.ExitStatus(status)
}

//main_test.go
// [...]
func TestRejectsRequestWithEmptyToken(t *testing.T) {
	RegisterTestingT(t)
    env, err := test.New(t, test.Request{
        Method:  "GET",
        Url:     "http://example.com/request-path",
        Headers: map[string][]string{"Authorization": {""},},
    })
    Expect(err).NotTo(HaveOccurred(), "failed execute test request: %s\n", err)

    env.DoHttps(&Config{})
	Expect(env.ClientRes.Status).To(Equal(401))
}
