断言等于 Junit 中的 2 个列表 [英] Assert equals between 2 Lists in Junit
问题描述
如何在 JUnit 测试用例中的列表之间进行相等断言?列表内容之间应该相等.
How can I make an equality assertion between lists in a JUnit test case? Equality should be between the content of the list.
例如:
List<String> numbers = Arrays.asList("one", "two", "three");
List<String> numbers2 = Arrays.asList("one", "two", "three");
List<String> numbers3 = Arrays.asList("one", "two", "four");
// numbers should be equal to numbers2
//numbers should not be equal to numbers3
推荐答案
对于 junit4!这个问题值得为 junit5<写一个新答案/a>.
我意识到这个答案是在提出问题几年后写的,可能当时还没有这个功能.但是现在,很容易做到这一点:
I realise this answer is written a couple years after the question, 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)));
}
如果您安装了带有 hamcrest 的最新版本的 Junit,只需添加这些导入:
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/最新/org/hamcrest/core/Is.html
