Does aetest.NewContext() require arguments?

I am learning how to create Golang tests for an Appengine app.

The documentation examples don't make sense to me.

https://cloud.google.com/appengine/docs/standard/go/tools/localunittesting/reference

Documentation seems to say you can create a context := aetest.NewContext()

When I attempt to do so, I'm getting an error that aetest.NewContext requires arguments.

$ go test -v  
  
./skincare_test.go:12: not enough arguments in call to aetest.NewContext  
	have ()  
	want (*aetest.Options)  
./skincare_test.go:12: assignment count mismatch: 3 = 2  
FAIL	_/Users/Bryan/work/gocode/skincarereview [build failed]  

content of skincare_test.go:

package skincare  
  
import (  
	"net/http"  
	"net/http/httptest"  
	"testing"  
  
	"appengine/aetest"  
)  
  
func TestIndexHandler(t *testing.T) {  
	ctx, done, err := aetest.NewContext()  
	if err != nil {  
		t.Fatal(err)  
	}  
	defer done()  
  
	req, err := http.NewRequest("GET", "/", nil)  
	if err != nil {  
		t.Fatal(err)  
	}  
  
	rr := httptest.NewRecorder()  
	handler := http.HandlerFunc(root) 
  
	handler.ServeHTTP(rr, req)  
  
	if status := rr.Code; status != http.StatusOK {  
		t.Errorf("handler returned wrong status code: got %v want %v",  
			status, http.StatusOK)  
	}  
  
	expected := "<div>Name"  
	if rr.Body.String() != expected {  
		t.Errorf("handler returned expected body: got %v want %v",  
			rr.Body.String(), expected)  
	}  
}

I learn best by looking at example code, where can I find examples of Tests for Go web applications that use Appengine datastore?

The examples in the documentation are so simple that I don't see how I'm supposed to do more complicated testing.

It says 2 things:

1. You are missing a required parameter *aetest.Options

2. that you can NOT assign result aetest.NewContext() that consist of 2 variable to a set of 3 variables.

Check what is the output of the function. I guess it is just (context.Context, error) - I suspect the done is moved to the *aetest.Options somehow.

Unfortunately my access to docs is blocked right now.

You are using the old version of the app engine package (appengine/aetest instead of google.golang.org/appengine/aetest). The newer version does not require arguments.
