如何将JUnit4的测试通过/失败结果记录到文件中? [英] How to log test pass/fail results of JUnit4 to a file?

问题描述

运行给定的JUnit4测试时，我希望它生成所有TestResults的日志文件.我不想通过CI/ant/maven来调用它. 我希望它可以在随时随地调用JUnit测试的任何时间运行.如果无法实现，那么我想编写自己的运行程序，该运行程序有问题地调用我的AllTestSuites类并记录所有结果本身. /p>

这将是我的测试班之一:

public class SimpleTestSuite extends TestCase{

    @Test
    public void simpleTestPass() {
        assertTrue(true);
    }

    @Test
    public void simpleTestFail() {
        assertTrue(false);
    }

    @Test
    public void simpleTestException() {
        throw new RuntimeException();
    }

}

我将其包含在TestSuite中，其中包含我要运行的所有测试套件:

@RunWith(Suite.class)
@Suite.SuiteClasses({SimpleTestSuite.class, ExampleSuite.class,})
public final class AllTestSuites {}

我想调用AllTestSuites并使其生成如下的日志文件.记住，我更喜欢捕获JUnit4框架的结果总线上的内容，而不是重新发明/创建一个新的测试运行器.

simpleTestPass - pass - 1/1 assertions passed
simpleTestFail - fail - 0/1 assertions passed
simpleTestException - exception - stacktrace as follows...

解决方案

在测试类和基础测试类中添加记录器，并将其定义为TestWatchMan，如下所示:

Logger logger = LoggerFactory.getLogger(TestCase.class);
@Rule public MethodRule watchman = new TestWatchman() {
   public void starting(FrameworkMethod method) {
      logger.info("Test {} is running.", method.getName());
   }
   public void succeeded(FrameworkMethod method) {
   logger.info("Test {} succesfully run.", method.getName());
   }
   public void failed(Throwable e, FrameworkMethod method) {
        logger.error("Test {} failed with {} reason.", 
                                                method.getName(), e.getMessage());
   }
};

When a given JUnit4 test runs, I want it to generate a logfile of all of its TestResults. I do not want to invoke this via CI/ant/maven. I want this to run anytime the JUnit test is called from anywhere. If that is not possible, then I would like to write my own runner which problematically invokes my AllTestSuites class and logs all the results itself.

Here would be one of my test classes:

public class SimpleTestSuite extends TestCase{

    @Test
    public void simpleTestPass() {
        assertTrue(true);
    }

    @Test
    public void simpleTestFail() {
        assertTrue(false);
    }

    @Test
    public void simpleTestException() {
        throw new RuntimeException();
    }

}

I included it in a TestSuite, which contains all of my test Suites to run:

@RunWith(Suite.class)
@Suite.SuiteClasses({SimpleTestSuite.class, ExampleSuite.class,})
public final class AllTestSuites {}

I want to invoke AllTestSuites and have it generate a log file such as below. Remember, I prefer to capture what is on the JUnit4 framework's result bus, and not to reinvent/create a new test runner.

simpleTestPass - pass - 1/1 assertions passed
simpleTestFail - fail - 0/1 assertions passed
simpleTestException - exception - stacktrace as follows...

解决方案

Add logger in you Test Class and Base Test Class and define as TestWatchMan as below:

Logger logger = LoggerFactory.getLogger(TestCase.class);
@Rule public MethodRule watchman = new TestWatchman() {
   public void starting(FrameworkMethod method) {
      logger.info("Test {} is running.", method.getName());
   }
   public void succeeded(FrameworkMethod method) {
   logger.info("Test {} succesfully run.", method.getName());
   }
   public void failed(Throwable e, FrameworkMethod method) {
        logger.error("Test {} failed with {} reason.", 
                                                method.getName(), e.getMessage());
   }
};
