intellij-idea - Intellij "java: package org.junit does not exist"

Question

当我尝试运行测试时，出现以下错误:
我在谷歌上查找并在谷歌上找到了一些东西，但这没有帮助。

Error:(3, 24) java: package org.junit does not exist
Error:(3, 1) java: static import only from classes and interfaces
Error:(5, 17) java: package org.junit does not exist
Error:(6, 17) java: package org.junit does not exist
Error:(12, 10) java: cannot find symbol
    symbol:   class Before
    location: class edu.kit.ipd.swt1.SimpleEditMeTest
Error:(17, 10) java: cannot find symbol
    symbol:   class Test
    location: class edu.kit.ipd.swt1.SimpleEditMeTest
[...]

我的测试代码:

package edu.kit.ipd.swt1;
import static org.junit.Assert.assertNotNull;
import org.junit.Before;
import org.junit.Test;

public class SimpleEditMeTest {
private EditMe editMe;
@Before
public void setUp() throws Exception {
    editMe = new EditMe();
}
@Test
public void test() {
    assertNotNull(editMe.getFoo());
}
}
