Unit Test AssertJ LocalDateTime with Examples

Table of Contents

許多測試驗證場景，提供開發者更流暢的驗證 API，驗證更直覺，使用流式斷言，不須再物件自己呼叫方法，流暢地寫完驗證，不須再寫迴圈， AssertJ LocalDateTime Unit Test with Examples 介紹 isEqualToIgnoringHours 、 isEqualToIgnoringMinutes 、 isEqualToIgnoringSeconds 等方法，本篇增加了範例，並透過單元測試來驗證產出結果。

單元測試

Examples AssertJ LocalDateTime Unit Test 斷言字串的主要目的是取得字串以進行斷言。

isEqualToIgnoringHours

驗證日期時間是否相等，忽略小時，若不成立，則會拋出 AssertionError 。

	@Test
	public void isEqualToIgnoringHours() {
		LocalDateTime value = LocalDateTime.of(2023, 10, 31, 5, 6, 7);
		LocalDateTime value2 = LocalDateTime.of(2023, 10, 31, 0, 6, 7);
		System.out.println(value);
		System.out.println(value2);
		assertThat(value).isEqualToIgnoringHours(value2);

		value = LocalDateTime.parse("2000-01-01T00:00:00");
		value2 = LocalDateTime.parse("2000-01-01T01:00:00");
		System.out.println(value);
		System.out.println(value2);
		assertThat(value).isEqualToIgnoringHours(value2);
	}

isEqualToIgnoringMinutes

Examples AssertJ LocalDateTime Unit Test 驗證日期時間是否相等，忽略分鐘，若不成立，則會拋出 AssertionError 。

	@Test
	public void isEqualToIgnoringMinutes() {
		LocalDateTime value = LocalDateTime.of(2023, 10, 31, 5, 6, 7);
		LocalDateTime value2 = LocalDateTime.of(2023, 10, 31, 5, 0, 7);
