java - The method is(int) is undefined

Question

I imported using the following:

import static org.junit.Assert.*;

But on the following line:

assertThat(0, is(1));

I get The method is(int) is undefined for the type AppTest.

The name of this method is so common in the English language that I can not find where to import this.

So my question is, where can I import is (and not).

Answer 1

你需要

import static org.hamcrest.Matchers.is;

is()其他很多大帮手都是hamcrest Matchers。当然，您需要以某种方式定义相应的依赖项。它可能会有点棘手，因为 hamcrest 有一些核心匹配器，并且匹配器类具有“所有”匹配器。但是一旦你确定哪一个最适合你，你就准备好了，一切都很好。

Answer 2

org.assertj.core.api.Assertions广泛提供测试用例....

import static org.assertj.core.api.Assertions.*;

assertThat(actual).isEqualTo(expected);
assertThat(actual).isNotEqualTo(expected);
