Testing

[AshleyCoder3]

I use this for creating a point and mongodb. everything runs great. But now im testing and im unsure how to hit the keys.set.... part of the function. any pointers or examples would be fantastic

Hello You can mock the t38c.Executor interface and initialize client this way:

client, err := t38c.NewWithExecutor(myExecutorMock, true)

Example using gomock:

package mypkg

import (
    "context"
    "testing"

    gomock "github.com/golang/mock/gomock"
    "github.com/stretchr/testify/require"
    "github.com/xjem/t38c"
)

func TestMock(t *testing.T) {
    ctrl := gomock.NewController(t)
    defer ctrl.Finish()

    e := NewMockExecutor(ctrl)

    gomock.InOrder(
        e.EXPECT().
            Execute(gomock.Any(), "PING", []string{}).
            Return([]byte(`{"ok": true, "ping":"pong"}`), nil),

        e.EXPECT().
            Execute(gomock.Any(), "SET", []string{"test", "1", "POINT", "1", "2"}).
            Return([]byte(`{"ok": true}`), nil),

        e.EXPECT().
            Execute(gomock.Any(), "GET", []string{"test", "1", "POINT"}).
            Return([]byte(`{"ok": true, "point": {"lat": 1, "lon": 2}}`), nil),
    )

    client, err := t38c.NewWithExecutor(e, true)
    require.NoError(t, err)

    err = client.Keys.Set("test", "1").Point(1, 2).Do(context.TODO())
    require.NoError(t, err)

    point, err := client.Keys.Get("test", "1").Point(context.TODO())
    require.NoError(t, err)

    require.Equal(t, &t38c.GetPointResponse{Point: t38c.Point{Lat: 1, Lon: 2}}, point)
}

Mocking raw bytes is a bit painful, but it works :) I will try to improve this in future
