Well, after "playing" a bit with run configurations of each unit test I noticed that each Run Config has a <code>Build</code> goal preset in the <code>Before Launch</code> option (See pic below): <a href="https://i.stack.imgur.com/e4WrZ.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/e4WrZ.jpg" alt="enter image description here"></a>

After changing <code>Build</code> to <code>Build Project</code> the tests run fine.

blocks|key|4383551|text|如果您正在使用像Junit's或Robolectric's这样的理论测试框架，请确保运行包含所需测试的类，而不是运行测试本身。因为这些框架使用测试方法作为实例方法，而不是静态方法，所以任何寻找普通public+static测试的测试框架都找不到任何东西。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4383552|entityMap|0|LINK|mutability|MUTABLE|url|https://github.com/junit-team/junit4/wiki/theories|1|https://blog.jayway.com/2015/03/19/parameterized-testing-with-robolectric/^0|2Q|D|8|7|0|G|D|1|0^^$0|@$1|2|3|4|5|6|7|P|8|@$9|Q|A|R|B|C]]|D|@$9|S|A|T|1|U]|$9|V|A|W|1|X]]|E|$]]|$1|F|3|-4|5|6|7|Y|8|@]|D|@]|E|$]]]|G|$H|$5|I|J|K|E|$L|M]]|N|$5|I|J|K|E|$L|O]]]]

If you're using a theory testing framework like <a href="https://github.com/junit-team/junit4/wiki/theories" rel="noreferrer">Junit's</a> or <a href="https://blog.jayway.com/2015/03/19/parameterized-testing-with-robolectric/" rel="noreferrer">Robolectric's</a>, make sure to run the class containing the test you want, instead the test itself. Since these frameworks use the test methods as instance methods instead of static methods, any testing framework looking for a normal <code>public static</code> test won't find anything.

blocks|key|4384224|text|除了这里的其他答案:当您在测试方法声明之前忘记@Test时，也会发生错误。IntelliJ+(2018.1)仍然会向您显示用于测试执行的绿色“播放按钮”，但是测试类中的那个公共方法将不是实际的测试。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4384225|entityMap^0|N|5|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

In addition to the other answers here: the error can also happen when you forget <code>@Test</code> before your test method declaration. IntelliJ (2018.1) will still show you the green "Play-Button" for test execution, but that public method in your Test-Class will not be an actual test.

blocks|key|4383752|text|确保您的@test方法和测试类都是public的。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4383753|entityMap^0|4|5|H|6|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

Make sure that your <code>@test</code> methods as well as the test class are <code>public</code>.

blocks|key|4384291|text|如果您没有将@Test注释放在测试方法之上，也会发生这种情况。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4384292|entityMap^0|6|5|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

This situation can also occur if you do not place <code>@Test</code> annotation above the test method.

blocks|key|4384243|text|也许你只是给测试方法起了一个错误的名字。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4384244|我遇到这个问题是因为我使用了“-”而不是intelliJ无法表示的“_”。|4384245|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Maybe you just give a wrong name for test method.

I met this problem because I used '—' instead of '_' which intelliJ cannot represent.

blocks|key|4384319|text|我必须在测试方法名称之前添加test。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4384320|methodtest()不工作，但testMethod()工作了|offset|length|style|CODE|4384321|entityMap^0|0|0|C|H|C|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@$D|L|E|M|F|G]|$D|N|E|O|F|G]]|9|@]|A|$]]|$1|H|3|-4|5|6|7|P|8|@]|9|@]|A|$]]]|I|$]]

I had to add test before the test Method Name.
<code>methodtest()</code> does not work but <code>testMethod()</code> worked

blocks|key|4384346|text|确保将@org.junit.Test添加到您的方法之上。我忘记了它们，这为我解决了这个问题！|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4384347|entityMap^0|3|F|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

Make sure <code>@org.junit.Test</code> is added on top of your method. I forgot them and that fixed it for me!

Make sure you've correct runner mentioned above your class.

I was getting this weird message when I was using runner <code>CucumberWithSerenity.class</code>. When I changed to <code>SerenityRunner.class</code> it got fixed.

<pre><code>@RunWith(SerenityRunner.class)
//@RunWith(CucumberWithSerenity.class)
public class WordPressAppTest {
</code></pre>

I'm using Serenity framework for web automation and use below runner class

<pre><code>import net.serenitybdd.cucumber.CucumberWithSerenity;
import net.serenitybdd.junit.runners.SerenityRunner;
import org.junit.runner.RunWith;
</code></pre>

I feel IDEA ( 2017.2.6 ) can show some better error message than this

You may check that Run/Debug Configurations in the top of the IntelliJ screen.
Delete all of then with the &quot;minus button&quot; and hit &quot;run&quot; green button again to run the test.
You may reload the project on the maven tab on the right as well.

In my spring mvc project. I solved this problem by adding
<pre><code>@RunWith(SpringJUnit4ClassRunner.class)
</code></pre>
to my test class.

I am experiencing a strange behavior of Intellij IDEA 2016.3. Having a class with method <code>foo</code> and a JUnit test for the method when I get <code>java.lang.Exception: No tests found matching Method foo</code> when running the test. After I do <code>mvn test</code> it succeeds and then running the unit test right after executing mvn command it suddenly runs green. Seems like IDEA does not compile automatically. How can I fix this?

P.S. No settings were altered after upgrading to v. 2016.3

java.lang.Exception: No tests found matching Method using Intellij IDEA

单元测试

我正在体验Intellij IDEA 2016.3的奇怪行为。有一个带有方法foo的类，并在运行测试时获得java.lang.Exception: No tests found matching Method foo时对该方法进行JUnit测试。在我执行mvn test之后，它成功了，然后运行单元测试，在执行mvn命令之后，它突然变绿了。看起来IDEA不会自动编译。我该如何解决这个问题呢？备注:升
