AbstractCharSequenceAssert.isNull介绍

[英]Verifies that the actual CharSequence is empty, i.e., it has a length of 0, or is null.

If you do not want to accept a null value, use org.assertj.core.api.AbstractCharSequenceAssert#isEmpty() instead.

Both of these assertions will succeed:

String emptyString = "" 
assertThat(emptyString).isNullOrEmpty(); 
String nullString = null; 
assertThat(nullString).isNullOrEmpty();

Whereas these assertions will fail:

assertThat("a").isNullOrEmpty(); 
assertThat("   ").isNullOrEmpty();

[中]验证实际CharSequence是否为空，即其长度是否为0，或者是否为null。
如果不希望接受空值，请使用org。资产j。果心应用程序编程接口。AbstractCharSequenceAssert#isEmpty（）代替。
这两种断言都将成功：

String emptyString = "" 
assertThat(emptyString).isNullOrEmpty(); 
String nullString = null; 
assertThat(nullString).isNullOrEmpty();

而这些断言将失败：

assertThat("a").isNullOrEmpty(); 
assertThat("   ").isNullOrEmpty();
