如何在assertj中验证元素是

Question

 result1 = {"AAA", "BBB"}
 result2 = {"DDD"}

String[] valid = String[]{"AAA", "BBB", "CCC"};

assertThat(result1).xxxx(valid);
assertThat(result2).xxxx(valid);

Answer 1

你可以反过来：

assertThat(valid).contains(result1);
assertThat(valid).contains(result2);

如果您坚持将结果放在左边，而将有效结果放在右边，则可以使用：

assertThat(result1).isSubsetOf(Arrays.asList(valid));
assertThat(result2).isSubsetOf(Arrays.asList(valid));

或者，为什么不将valid定义为集合而不是数组呢？

Set<String> valid = Sets.newHashSet("AAA", "BBB", "CCC"); //Sets comes from google guava
assertThat(result1).isSubsetOf(valid);
assertThat(result2).isSubsetOf(valid);
