Junit的打印测试结果

Question

当前我正在使测试案例重复2次，因此如何将结果打印为2个单独的结果。

我尝试使用内置函数创建文本，但是，它确实显示了"成功"或"失败"。

目前我有此代码：

public class UnitTestRunner {
    static JUnitCore junitCore;
    static Class<?> testClasses;
    public static void main(String[] args) {
        System.out.println("Running Junit Test Suite.");
        Result result = JUnitCore.runClasses(TestSuite.class);
        for (Failure failure : result.getFailures()) {
            System.out.println(failure.toString());
        }
        System.out.println("Successful: " + result.wasSuccessful() +
            " ran " + result.getRunCount() + " tests");
    }
}

此代码正常工作，但我不知道如何将其实施到Junit。

有人可以帮助显示，如何将此代码实施到JUNIT测试案例中。

这将是稍长的答案。对于自定义输出，您必须添加RunListener您可以将以下示例实现使用。

public class UnitTestRunner {
    static JUnitCore junitCore;
    static Class<?> testClasses;
    public static void main(String[] args) {
        System.out.println("Running Junit Test Suite.");
        junitCore = new JUnitCore();
        junitCore.addListener(new CustomExecutionListener());
        Result result = junitCore.run(TestSuite.class);
        for (Failure failure : result.getFailures()) {
            System.out.println(failure.toString());
        }
        System.out.println("Successful: " + result.wasSuccessful() + " ran " + result.getRunCount() + " tests");
    }
}

和RunListener的实现如下

import org.junit.runner.Description;
import org.junit.runner.Result;
import org.junit.runner.notification.Failure;
import org.junit.runner.notification.RunListener;
public class CustomExecutionListener extends RunListener {
    public void testRunStarted(Description description) throws Exception {
        System.out.println("Number of tests to execute: " + description.testCount());
    }
    public void testRunFinished(Result result) throws Exception {
        System.out.println("Number of tests executed: " + result.getRunCount());
    }
    public void testStarted(Description description) throws Exception {
        System.out.println("Starting: " + description.getMethodName());
    }
    public void testFinished(Description description) throws Exception {
        System.out.println("Finished: " + description.getMethodName());
    }
    public void testFailure(Failure failure) throws Exception {
        System.out.println("Failed: " + failure.getDescription().getMethodName());
    }
    public void testAssumptionFailure(Failure failure) {
        System.out.println("Failed: " + failure.getDescription().getMethodName());
    }
    public void testIgnored(Description description) throws Exception {
        System.out.println("Ignored: " + description.getMethodName());
    }
}

，通过覆盖RunListener中的方法，您可以格式化输出。
