Examples

NewStdin

func Test(t *testing.T) {
    inio := stdio.NewStdin("testing!\n")
    err := inio.Capture()
    So(err, ShouldEqual, nil)
    var data []byte
    data, err = io.ReadAll(os.Stdin)
    So(err, ShouldEqual, nil)
    So(data, ShouldEqual, []byte("testing!\n"))
}

NewStdout

func Test(t *testing.T) {
    outio := stdio.NewStdout()
    err := outio.Capture()
    So(err, ShouldEqual, nil)
    _, err = os.Stdout.WriteString("testing!\n")
    So(err, ShouldEqual, nil)
    So(outio.Data(), ShouldEqual, []byte("testing!\n"))
}

NewStderr

func Test(t *testing.T) {
    errio := stdio.NewStderr()
    err := errio.Capture()
    So(err, ShouldEqual, nil)
    _, err = os.Stderr.WriteString("testing!\n")
    So(err, ShouldEqual, nil)
    So(errio.Data(), ShouldEqual, []byte("testing!\n"))
}
