在Junit中断言列表 [英] Assert List in Junit

问题描述

如何在 JUnit 测试用例中声明列表？

How to assert list in JUnit test case? I mean not only the size of the list but also the contents of the list.

推荐答案

我意识到这是问了几年以前，可能这个功能不是那时。但现在，很容易做到这一点：

I realise this was asked a couple years ago, probably this feature wasn't around then. But now, it's easy to just do this:

@Test
public void test_array_pass()
{
  List<String> actual = Arrays.asList("fee", "fi", "foe");
  List<String> expected = Arrays.asList("fee", "fi", "foe");

  assertThat(actual, is(expected));
  assertThat(actual, is(not(expected)));
}

如果您使用hamcrest安装了最新版本的Junit， ：

If you have a recent version of Junit installed with hamcrest, just add these imports:

import static org.junit.Assert.*;
import static org.hamcrest.CoreMatchers.*;

http://junit.org/junit4/javadoc/latest/org/junit/Assert.html#assertThat（ T，org.hamcrest.Matcher）

http://junit.org/junit4/javadoc/latest/org/hamcrest/CoreMatchers.html

http://junit.org/junit4/javadoc/latest /org/hamcrest/core/Is.html
