如何使用AssertJ检查字符串是否是给定值之一？

Question

如何以更简单的方式检查字符串是否与给定选项之一匹配？

List<String> OPTIONS = Arrays.asList("alpha", "beta", "gamma");
String text = "beta";
assertThat(OPTIONS.stream().anyMatch(o -> o.equals(text))).isTrue();

Answer 1

AssertJ:org.assertj.core.api.AbstractAssert::isin中有一个内置解决方案

@Test
public void testOneOf() {
  List<String> OPTIONS = Arrays.asList("alpha", "beta", "gamma");

  String text = "beta";

  Assertions.assertThat(text)
    .as("Should contain one value from OPTIONS")
    .isIn(OPTIONS);
}
