You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: routes_test.go
    path of file: ./repos/go-oauth2-server/oauth
    
    the code of the file until where you have to start completion: package oauth_test

import (
	"net/http"

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

func (suite *OauthTestSuite) TestTokensRouteIsValid() {
	r, err := http.NewRequest(
		"POST",
		"http://1.2.3.4/v1/oauth/tokens",
		nil,
	)
	assert.NoError(suite.T(), err, "New request should not
    
func (suite *OauthTestSuite) TestIntrospectRouteIsValid() {
	r, err := http.NewRequest(
		"POST",
		"http://1.2.3.4/v1/oauth/introspect",
		nil,
	)
	assert.NoError(suite.T(), err, "New request should not cause an error")

	// Check the routing
	match := new(mux.RouteMatch)
	suite.router.Match(r, match)
	if assert.NotNil(suite.T(), match.Route, "Expected to find a route match") {
		assert.Equal(suite.T(), "oauth_introspect", match.Route.GetName(), "Expected route to be matched")
	}
}
