If you use maven and this piece of code is located in the <code>main</code> folder, try relocating it to the <code>test</code> folder.

blocks|key|151793|text|您可以很容易地搜索像"@Test“这样的行，然后在该行使用快速修复"add+junit+4+library+to+the+build+path”。我认为这比手动将junit添加到项目中更快。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|151794|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

you can easily search for a line like "@Test" and then use the quickfix "add junit 4 library to the build path" at this line. i think this is faster than adding junit manually to the project.

Right-click on your root folder.

you need to add Junit dependency in pom.xml file, it means you need to update with latest version.

<pre><code>&lt;dependency&gt;
 &lt;groupId&gt;junit&lt;/groupId&gt;
 &lt;artifactId&gt;junit&lt;/artifactId&gt;

I had the same problem right now. My solution: add JUnit to the pom.xml AND remove JUnit from the eclipse project properties (Java Build Path/Libraries).

Update to latest JUnit version in pom.xml. It works for me.

I need to solve a java problem for an interview, and they have sent me the test class. It starts with 

<pre><code>import org.junit.Before;
</code></pre>

and also has the following syntax at places:

<pre><code>@RunWith(JUnit4.class)
...
@Before
...
@Test
</code></pre>

I haven't used Java in a while so this confuses me a little. I downloaded eclipse and when I try to compile this test file there's errors at the import and at the @ signs. The import error throws: 

<pre><code>The import org.junit cannot be resolved.
</code></pre>

And the @RunWith is not even recognized because it tries to resolve it to a type.

The import org.junit cannot be resolved

我需要为面试解决一个java问题，他们已经给我发来了测试类。它的开头是import org.junit.Before;并且在某些地方还具有以下语法：@RunWith(JUnit4.class)...@Before...@Test我已经有一段时间没有使用Java了，所以这让我有点困惑。我下载了eclipse，当我试图编译这个测试文件时，在导入和@符号处出现了错误。导入错误抛出：The import
