func TestSnapshot(t *testing.T) {
s := New()
_ = s.Snapshot("xxx")
_ = s.Snapshot("xxx")
_ = s.Snapshot("xxxy")
s.Assert(t)
}
func TestSnapshotBytes(t *testing.T) {
s := New()
_ = s.SnapshotBytes([]byte("吉野家"))
s.Assert(t)
}
func TestCanUseAsIoWriter(t *testing.T) {
s := New()
b := bytes.NewBufferString("test")
_, _ = io.Copy(s, b)
s.Assert(t)
