在 Eclipse 中找不到作为 junit 测试运行

Question

I created a test class in Eclipse like this

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:applicationContext.xml" })
@TransactionConfiguration
@Transactional
public class TeamTest extends AbstractTransactionalJUnit4SpringContextTests {

 @Test
 public void testCreate() {


  assert (true);
 }}

However, when I click right click on the file I don't see option to run as JUnit!

What is wrong?

I am using Eclipse 3.6

Answer 1

Make sure your eclipse environment is using JUnit 4. JUnit 3 doesn't make use of annotations (it uses the old extends TestCase style)

There are few things to double check:

Window > Preferences > Java > JUnit

Are you seeing junit4 or junit3 imports? If that looks good, make sure the project itself is using JUnit4 instead of JUnit3.

Right Click on project > Properties > Java Build Path > Libraries

Is JUnit4 included there? Is anything JUnit related there? If JUnit3 is in there, click on it and click Remove . Then click Add Library... and follow the prompts from there to add JUnit again.

Out of curiosity, are the JUnits run outside of eclipse? Like with a mvn install or whatever build target you have for Ant that'll run JUnits

Answer 2

Write a simple test case to see if Eclipse works correctly or not. If simple test case can be run, check your testcase, especially import classes.

Or make a try in "Run" -> "Run Configurations",fill the "Test class" as " TeamTest "(full class name). Then click "Run", see what will happen...

Answer 3

The way I fixed it is by changing Test runner in the Run Configuration from the default Junit3 to Junit4. Once I made this change I could see the option Junit when I right clicked on the test class and expanded Run As

I encountered the same issue and verified all the settings (above mentioned) are fine. A small change (version to 1.5.21.RELEASE from 2.5.0-M2) in pom.xml resolved my issue (below). This Iam able to recreate consistently.

STS Details Version: 3.9.0.RELEASE Build Id: 201707061823 Platform: Eclipse Oxygen (4.7.0)

Pom.xml change

FROM

<modelVersion>4.0.0</modelVersion>
<parent>
         <groupId>org.springframework.boot</groupId>
         <artifactId>spring-boot-starter-parent</artifactId>
         **<version>2.5.0-M2</version>**
         <relativePath/> <!--  lookup parent from repository  -->
</parent>

TO

<modelVersion>4.0.0</modelVersion>
<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>

确保你使用 Junit 作为你的测试框架，而不是像 TestNg 这样涵盖大部分 Junit 目的的东西。
