🔥 Add support or documentation for unit tests about fiber HOT 10 CLOSED

How can I use this feature from a _test.go file? It appears you need a reference to app variable.

You can prepare a function, which creates a Fiber app and use middleware(s) that you want to test.
For example:

func setupApp() *fiber.App {
	app := fiber.New()
	app.Use(authenticate.New(), attachuser.Handle, authorize.Handle)
	authenticateduser.Setup(app)

	return app
}

Then use that function in your test codes:

const bearerToken = "Bearer o8SMWsPx.9wJ7nZ86.XUyQV3yu"

func TestGet(t *testing.T) {
	app := setupApp()

	req := httptest.NewRequest("GET", "/", nil)
	req.Header.Set("Authorization", bearerToken)

	res, _ := app.Test(req)
}

func TestPatch_Profile(t *testing.T) {
	app := setupApp()

	const reqBody = `{
		"scope": "profile",
		"data": {
		  "name": "My New Name"
		}
	}`

	req := httptest.NewRequest("PATCH", "/", strings.NewReader(reqBody))
	req.Header.Set("Authorization", bearerToken)

	res, _ := app.Test(req)
}

func TestPatch_Password(t *testing.T) {
	app := setupApp()

	const reqBody = `{
		"scope": "password",
		"data": {
		  "oldPassword": "qwerty",
		  "newPassword": "12qwaszx"
		}
	}`

	req := httptest.NewRequest("PATCH", "/", strings.NewReader(reqBody))
	req.Header.Set("Authorization", bearerToken)

	res, _ := app.Test(req)
}

Thanks for your kind words @schweigert, welcome!

What about a method named Test so you can pass a raw HTTP string or *http.Request struct to test your application locally.

Raw HTTP string

package main

import (
  "fmt"
  "github.com/gofiber/fiber"
)

func main() {
  app := New()
  app.Get("/demo", func(c *Ctx) {
    fmt.Println(c.BaseURL()) // => http://google.com
  })

  body, err := app.Test("GET /demo HTTP/1.1\r\nHost: google.com\r\n\r\n")
  fmt.Println(body, err)
}

Using http.Request

package main

import (
  "fmt"
  "github.com/gofiber/fiber"
)

func main() {
  app := New()
  app.Get("/demo", func(c *Ctx) {
    fmt.Println(c.BaseURL()) // => http://google.com
  })

  req, _ := http.NewRequest("GET", "http://google.com/demo", nil)
  req.Header.Set("X-Custom-Header", "hi")

  body, err := app.Test(req)
  fmt.Println(body, err)
}

What do you think @schweigert? Let us know so we can implement this feature 👍

from fiber.

This looks good, but I still can't test the status code of the request. I believe that the return should not be a string, but a response, from the http package.

from fiber.

Maybe we should drop the raw http string and only work with http.Request & http.Response.
@koddr, what do you think?

I wish the wiki were in GitHub. https://fiber.wiki is currently unavailable.
