junitTestThread

 In JUnit, you can use the @Test annotation to mark a method as a test method, which means that it will be executed when you run your JUnit tests.

If you want to prevent a class from running a method when it is in testing mode, you can do this by checking whether the current thread is a JUnit test thread. JUnit test threads are created when a JUnit test is run, and they are identified by the org.junit.Test class being present in the call stack.

Here is an example of how you can check if the current thread is a JUnit test thread and skip running a method if it is:

public class MyClass {
  public void doSomething() {
    // Check if the current thread is a JUnit test thread
    if (isJUnitTestThread()) {
      // Skip running the method if it is a JUnit test thread
      return;
    }

    // Do something here
  }

  private static boolean isJUnitTestThread() {
    // Get the current thread's stack trace
    StackTraceElement[] stackTrace = Thread.currentThread().getStackTrace();

    // Check if any of the stack trace elements is from the org.junit.Test class
    for (StackTraceElement element : stackTrace) {
      if (element.getClassName().equals("org.junit.Test")) {
        return true;
      }
    }

    return false;
  }
}

In this example, the doSomething method checks if the current thread is a JUnit test thread by calling the isJUnitTestThread method. If it is a JUnit test thread, the method skips running the rest of its code and returns. Otherwise, it continues to execute its code.

The isJUnitTestThread method gets the current thread's stack trace and checks if any of the stack trace elements is from the org.junit.Test class. If it finds one, it returns true, indicating that the current thread is a JUnit test thread. Otherwise, it returns false.

Note that this approach only works if the method you want to skip running is called directly from a JUnit test method. If the method is called indirectly, for example from another method that is called from a JUnit test method, it will not be skipped. In that case, you may need to use a different approach, such as using a global flag to indicate whether the class is in testing mode.
