httpcheck Goa plugin

This plugin provides a mounter for the Goa HTTP endpoints, enabling seamless integration with httpcheck. The mounter satisfies the http.Handler interface, allowing it to be directly set and utilized within httpcheck.

Usage Example

The following example demonstrates how to use the goa plugin to test a Goa HTTP endpoint. In this example, we're testing an endpoint that multiplies two numbers.

package calc

import (
	"io"
	"net/http"
	"strconv"
	"strings"
	"testing"

	"github.com/ikawaha/httpcheck"
	"github.com/ikawaha/httpcheck/plugin/goa"
	gen "github.com/ikawaha/httpcheck/plugin/goa/calc/gen/calc"
	"github.com/ikawaha/httpcheck/plugin/goa/calc/gen/http/calc/server"
	"github.com/stretchr/testify/assert"
	"github.com/stretchr/testify/require"
)

func TestMounter(t *testing.T) {
	m := goa.NewMounter()
	m.Mount(goa.EndpointModular{
		Builder:  server.NewMultiplyHandler,
		Mounter:  server.MountMultiplyHandler,
		Endpoint: gen.NewMultiplyEndpoint(NewCalc()),
	})
	httpcheck.New(m).Test(t, "GET", "/multiply/3/5").
		Check().
		MustHasStatus(http.StatusOK).
		Cb(func(r *http.Response) {
			b, err := io.ReadAll(r.Body)
			require.NoError(t, err)
			i, err := strconv.Atoi(strings.TrimSpace(string(b)))
			assert.NoError(t, err, string(b))
			assert.Equal(t, 3*5, i)
		})
}
