调试用Spock和JMockit测试的Java代码 [英] Debugging Java code tested with Spock and JMockit

问题描述

我正在使用Spock为Java应用程序编写测试。该测试包括该类的JMockit MockUp 。在调试测试时（使用IntelliJ），我希望能够进入Java代码。我意识到使用 F5 来进入代码将不起作用，因为所有的Groovy魔法都会反射出去。不幸的是，即使我在Java代码中设置了断点，它仍然不会被触发，即使它运行在代码中。

以下是要测试的代码：

  public class TestClass {
 
 private static void initializeProperties（）{
 // Code在测试期间不会运行
} 
 
 public static boolean getValue（）{
 return true; //< === BREAK POINT SET此处永远不会是HIT 
} 
} 
  

以下是测试代码：

  class TestClassSpec extends Specification {
 
 void setup（ ）{
 new MockUp< TestClass>（）{
 @Mock 
 public static void initializeProperties（）{} 
} 
} 
 
 voidrun test（）{
 when：
 boolean result = TestClass.getValue（）
 
 then：
 result == true 
} 
} 
  

测试通过并且一切正常，但我无法调试到Java代码。

注意：如果我不使用JMockit MockUp ，但是在我的生产代码中测试 private static 方法是必需的。

让调试器停止在使用JMockit的Spock测试中的Java代码中？

解决方案

这个答案困扰了我好几天，而且我搜索并搜索了一个答案。在发布求助之后15分钟，我找到了答案。因此，对于遇到此问题的任何人，这里是我的解决方案 - 这一切都要归功于此答案： https://stackoverflow.com/a / 4852727/2601060

简而言之，当JMockit重新定义类时，将删除断点。解决方法是在测试中设置一个断点，一旦调试器停止在测试中，那么在Java代码中设置断点。

<有很多欢乐......

I'm using Spock to write tests for a Java application. The test includes a JMockit MockUp for the class. When debugging a test (using IntelliJ) I would like to be able to step into the Java code. I realize using F5 to step into the code won't work, because of all the Groovy magic with reflection that goes on. Unfortunately, even if I set a breakpoint in the Java code, it still will not be hit, even though it runs through the code.

Here is the code to test:

public class TestClass {

    private static void initializeProperties() {
        // Code that will not run during test
    }

    public static boolean getValue() {
        return true;  // <=== BREAK POINT SET HERE WILL NEVER BE HIT
    }
}

Here is the test code:

class TestClassSpec extends Specification {

    void setup() {
        new MockUp<TestClass>() {
            @Mock
            public static void initializeProperties() {}
        }
    }

    void "run test"() {
        when:
        boolean result = TestClass.getValue()

        then:
        result == true
    }
}

The test passes and everything works well, but I'm not able to debug into the Java code.

Note: I can debug if I do not use the JMockit MockUp, but that is required to test a private static method in my production code.

Any ideas on how to get the debugger to stop in the Java code from a Spock test that uses JMockit?

解决方案

This answer has plagued me for days, and I have searched and searched for an answer. Fifteen minutes after posting for help, I find the answer . So for anyone else who runs into this, here's my solution - this is all thanks to this answer: https://stackoverflow.com/a/4852727/2601060

In short, the breakpoint is removed when the class is redefined by JMockit. The solution is to set a break point in the test, and once the debugger has stopped in the test THEN set the breakpoint in the Java code.

And there was much rejoicing...
