我想在BeforeSuit中启动我的应用并运行GET请求。那可能吗?
example_suite_test.go
func TestExample(t *testing.T) {
RegisterFailHandler(Fail)
RunSpecs(t, "Example Suite")
}
example_test.go
var appTest *app.Application
var _ = BeforeSuite(func() {
app = &app.Application{}
app.Run(":8080") // runs http.ListenAndServe on given address
})
var _ = Describe("Example", func() {
Context("When calling '/example' endpoint...", func() {
req, err := http.NewRequest("GET", "http://localhost:8080/example", nil)
client := http.DefaultClient
res, err := client.Do(req)
It("Should get response 200 OK", func() {
Expect(res.Status).To(Equal("200 OK"))
})
})
})
目前似乎正在启动服务器,而不是继续测试。如果我删除BeforeSuite,而是启动服务器并运行测试,那似乎很好。
我想app.Run
会阻塞,因为http.ListenAndServe
会阻塞,在这种情况下,您可能需要这样做:
var _ = BeforeSuite(func() {
app = &app.Application{}
go func() {
app.Run(":8080") // runs http.ListenAndServe on given address
}()
})
但是,通常,您实际上不会在端口上监听单元测试,而应该这样做:
var _ = Describe("Example", func() {
Context("When calling '/example' endpoint...", func() {
req, err := http.NewRequest("GET", "http://localhost:8080/example", nil)
// We create a ResponseRecorder (which satisfies http.ResponseWriter) to record the response.
rr := httptest.NewRecorder()
handler := http.HandlerFunc(app.ExampleHandler)
// Our handlers satisfy http.Handler, so we can call their ServeHTTP method
// directly and pass in our Request and ResponseRecorder.
handler.ServeHTTP(rr, req)
It("Should get response 200 OK", func() {
Expect(rr.Result().Status).To(Equal("200 OK"))
})
})
