Need a proper documentations on Testing

[jamesli2021]

It's important that the document should be friendly and in complete (no partial code) no matter if Echo is targetting newbies or professionals:
https://echo.labstack.com/guide/testing/#using-form-payload

Testing is an important asset and spent hours trying to understand an incomplete tutorials is a big waste of time.
I will appreciate any members of the Echo teach or who use testify to contribute or there will be more problem down the road.

For the info, I was testing to write a payload form by posting and missing out other code yet to be written.

import (
	"net/http"
	"net/http/httptest"
	"net/url"
	"strings"
	"testing"

	"github.com/labstack/echo/v4"
)

func TestGetUser(t *testing.T) {
	e := echo.New()
	f := make(url.Values)
	f.Set("name", "Jon Snow")
	f.Set("email", "[email protected]")
	req := httptest.NewRequest(http.MethodPost, "/", strings.NewReader(f.Encode()))
	req.Header.Set(echo.HeaderContentType, echo.MIMEApplicationForm)
	
	rec := httptest.NewRecorder()

	c := e.NewContext(req, rec)

}

your example works perfectly fine for me.

import (
	"log"
	"net/http"
	"net/http/httptest"
	"net/url"
	"strings"
	"testing"

	"github.com/labstack/echo/v4"
)

func TestGetUser(t *testing.T) {
	e := echo.New()
	f := make(url.Values)
	f.Set("name", "Jon Snow")
	f.Set("email", "[email protected]")
	req := httptest.NewRequest(http.MethodPost, "/", strings.NewReader(f.Encode()))
	req.Header.Set(echo.HeaderContentType, echo.MIMEApplicationForm)

	rec := httptest.NewRecorder()

	c := e.NewContext(req, rec)
	log.Println(c)
}

@aldas
Should I concern this errors? I seen this problem even ran go mod tidy command.

[aldas]

you probably need to restart your IDE and it will go away

[jamesli2021]

Yes, the problem went away after restarting.

If I may ask how do I really get 404 error status after which I have set in the handler if name is empty but testify is alway returning 200, does sounds like a blackbox to me and error prone is the test isn't written correctly. I have googled and reading code all over the web, how does it actually get different status code?

Or other testing libraries are more suitable for testing CRUD?

e := echo.New()
values := make(url.Values)
values.Set("name", "")
req := httptest.NewRequest(http.MethodPost, "/signup", strings.NewReader(values.Encode()))
req.Header.Set(echo.HeaderContentType, echo.MIMEApplicationForm)
resp := httptest.NewRecorder()
e.NewContext(req, resp)
assert.Equal(t, http.StatusOK, resp.Code)
