Proposal: add support for mocking unexported functions about xgo HOT 3 CLOSED

Update: added support to anonymous function, i.e. closures.

See commit d6c2b3d
Example:

package mock_closuer

import (
	"context"
	"testing"

	"github.com/xhd2015/xgo/runtime/core"
	"github.com/xhd2015/xgo/runtime/mock"
)

var gc = func() {
	panic("gc should be mocked")
}

func TestMockClosure(t *testing.T) {
	var lc = func() {
		panic("lc should be mocked")
	}
	mock.Mock(gc, func(ctx context.Context, fn *core.FuncInfo, args, results core.Object) error {
		return nil
	})
	gc()

	mock.Mock(lc, func(ctx context.Context, fn *core.FuncInfo, args, results core.Object) error {
		return nil
	})
	lc()
}

from xgo.

Mocking unexported method, is that even possible?

This proposal to go: golang/go#19752 was declined. There is no way to get an unexported method through reflect.

This proposal to go: golang/go#19752 was declined. There is no way to get an unexported method through reflect.

We take another way: do not rely on reflect.Method, instead, use reflect.Type as a key to hold all methods for given method.

See commit 6178bd0

Now xgo supports mocking unexported functions and methods, see document runtime/mock/README.md
