### 編集 { #edit-it }

これはとても簡単なプログラムです。

しかし、今、あなたがそれを一から書いていたと想像してみてください。

パラメータの準備ができていたら、そのとき、関数の定義を始めていたことでしょう...

しかし、そうすると「最初の文字を大文字に変換するあのメソッド」を呼び出す必要があります。

それは `upper` でしたか？`uppercase` でしたか？`first_uppercase`？`capitalize`？

そして、古くからプログラマーの友人であるエディタで自動補完を試してみます。

関数の最初のパラメータ `first_name` を入力し、ドット（`.`）を入力してから、`Ctrl+Space` を押すと補完が実行されます。

しかし、悲しいことに、これはなんの役にも立ちません:

            // Then
            assertNotNull(parsedMessage);
            assertEquals(TEST_TARGET.toUpperCase(), parsedMessage.getTarget()); // OEM encoding often means uppercase
        }

        @Test
        @DisplayName("parse should handle message with no target name")
        void testParse_NoTargetName() throws IOException {
            // Given

	Xattrs map[string]string

	// PAXRecords is a map of PAX extended header records.
	//
	// User-defined records should have keys of the following form:
	//	VENDOR.keyword
	// Where VENDOR is some namespace in all uppercase, and keyword may
	// not contain the '=' character (e.g., "GOLANG.pkg.version").
	// The key and value should be non-empty UTF-8 strings.
	//
	// When Writer.WriteHeader is called, PAX records derived from the
