这个异常通常是由于 JUnit 测试类中没有可运行的测试方法导致的。要解决这个问题,请检查你的测试类,并确保存在可以运行的测试方法。测试方法必须用 @Test 注解进行标记,而且方法签名必须符合 JUnit 的要求。例如:
```
import org.junit.Test;
import static org.junit.Assert.*;
public class MyTest {
@Test
public void testSomething() {
// 测试代码
}
}
```
在这个示例中,`testSomething()` 方法被 `@Test` 注解标记,因此它将被 JUnit 运行。如果你的测试类中没有任何可运行的测试方法,则会触发 `No runnable methods` 异常。

java.lang.exception: no runnable methods
"java.lang.exception: no runnable methods" 意思是在类中没有可运行的方法。这通常是由于没有在类中定义 main 方法导致的。为了解决这个问题,请在类中添加一个 main 方法并确保它是 public static 的。
java.lang.Exception: No runnable methods
This exception is thrown when JUnit cannot find any test methods to run in the class or suite being executed.
To resolve this issue, you need to ensure that your test class contains at least one method annotated with the @Test annotation. Make sure that the method has a public access modifier and does not return a value.
If you are using a test suite to run multiple test classes, make sure that each of the classes included in the suite contains at least one runnable test method.
If you are still encountering this error, check your JUnit version and ensure that it is compatible with your project. Additionally, make sure that your test class is in the correct package and that your IDE is properly configured to run JUnit tests.
