Go Code Review Comments

原文

go fmt

あなたのコードに gofmt を走らせると、自動的に機械的に直すことのできるスタイルの大部分を修正してくれます。 世にあるGolang コードのほとんどすべてが gofmt を使っています。 この文章の残りは機械的に直すことのできないポイントについて解説します。

代わりに goimports を使う手段もあります。

Be Careful with Table Driven Tests and t.Parallel()

We Gophers, love table-driven-tests, it makes our unittesting structured, and makes it easy to add different test cases with ease.

Let’s create our table driven test, for convenience, I chose to use t.Log as the test function. Notice that we don't have any assertion in this test, it is not needed to for the demonstration.

func TestTLog(t *testing.T) {
	t.Parallel()
