问题
Debug Partial Mock in JMockit和
Debugging Java code tested with Spock and JMockit已经解决了这个问题,当JMockit重新定义/检测类时,被测试软件(SUT)中的断点会被忽略.
建议的解决方案是,一旦执行在测试类中停止,您应该在测试类中添加一个额外的断点,以便重新激活SUT中的断点.
但是,如果在测试类中使用@Tested批注,则此解决方案不起作用,因为在这种情况下,测试类本身中的断点将被忽略.
这是一个例子:
package de.playground;
import static org.hamcrest.Matchers.is;
import static org.junit.Assert.assertThat;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import mockit.Expectations;
import mockit.Injectable;
import mockit.integration.junit4.JMockit;
@RunWith(JMockit.class)
public class DebuggingWithJMockitTest {
public interface Collaborator {
String execute(String... args);
}
public static class ToTest {
private Collaborator collaborator;
public ToTest(Collaborator collaborator) {
this.collaborator = collaborator;
}
public String doSomething() {
return collaborator.execute("a", "b");
}
}
@Injectable
private Collaborator collaborator;
@Tested
private ToTest toTest;
@Test
public void testHoldOnBreakpoint() {
new Expectations() {{
collaborator.execute((String[]) any); result = "whatever";
}};
String result = toTest.doSomething(); // add breakpoint here
assertThat(result, is("whatever"));
}
}
在这种情况下,调试器不会停止在String result = toTest.doSomething();线.如果您不使用@Tested批注并在@Before方法中初始化SUT,请执行以下操作:
// @Tested is not used
private ToTest toTest;
@Before
public void before() {
toTest = new ToTest(collaborator);
}
断点工作得非常好.
即使您在测试类中使用@Testedannotation,是否有任何解决方法可以调试代码?
最佳答案 JMockit Google Group上的这个错误
was brought up:
Yes, the problem is known, and already solved in JMockit 1.24.
看起来没有记录它的问题.我们的团队在JMockit 1.23上遇到了这个问题,并且确实能够通过升级到JMockit 1.24来克服它.
