Question

在我全新的Play 2.3.1 Java应用程序中，我编写了第一个测试，但它们根本不起作用。我启动activator test，直接放在test目录中的默认包中的简单测试类尚未到达。

import org.junit.Assert;
import org.junit.Test;

public class TestTest {

    @Test
    public void testTest() {
        Assert.assertEquals(true, false);
    }
}

当我启动activator testOnly TestTest时，我有以下输出：

[info] Passed: Total 0, Failed 0, Errors 0, Passed 0
[info] No tests to run for test:testOnly
[success] Totaltime: 6 s, completed 11 juil. 2014 09:08:38

可能是什么原因？

Answer 1

遇到没有发现任何测试的同一问题; activator clean解决了这个问题。

Answer 2

它对我有用，因此您的问题需要更多细节才能找到有用的解决方案。

运行activator --version以检查版本。我的基础是sbt发射器0.13.5。

➜  sandbox  activator --version
sbt launcher version 0.13.5

关于激活剂本身的版本并没有太多说明（但激活剂1.2.x可能是0.13.5）。如果您的年龄较大，请升级。

使用activator new my-brand-new-play-app play-java来创建Play / Java应用程序。

➜  sandbox  activator new my-brand-new-play-app play-java

Fetching the latest list of templates...

OK, application "my-brand-new-play-app" is being created using the "play-java" template.

To run "my-brand-new-play-app" from the command line, "cd my-brand-new-play-app" then:
/Users/jacek/sandbox/my-brand-new-play-app/activator run

To run the test for "my-brand-new-play-app" from the command line, "cd my-brand-new-play-app" then:
/Users/jacek/sandbox/my-brand-new-play-app/activator test

To run the Activator UI for "my-brand-new-play-app" from the command line, "cd my-brand-new-play-app" then:
/Users/jacek/sandbox/my-brand-new-play-app/activator ui

然后我将您的TestTest课程复制到test/TestTest.java，但没有任何更改：

➜  my-brand-new-play-app  cat test/TestTest.java
import org.junit.Assert;
import org.junit.Test;

public class TestTest {

    @Test
    public void testTest() {
    Assert.assertEquals(true, false);
    }
}

创建测试文件的唯一变化是，我运行了activator test。经过大量文件下载后，结果为：

TestTest测试确实已执行。

我还使用'testOnly TestTest'执行了TestTest，如下所示：

总而言之，它运作良好。我不确定你的问题究竟是什么，因为我跟你的步骤一样严格地跟着问题的描述。

当Eclipse运行时，activator clean的解决方案有时不起作用。关闭Eclipse然后执行activator clean然后为我工作。

为什么JUnit测试不能在Play 2.3.1 / Java项目中运行？
