Question

目前我正在使测试用例重复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，但现在它显示“成功”或“失败”。

目前我有这段代码：

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");
    }
}

此代码工作正常，但我不知道如何将其实现为JUnit。

有人可以帮助展示，如何将此代码实现到JUnit测试用例中。

这将是一个稍长的答案。对于自定义输出，您必须添加RunListener 您可以使用以下示例实现。

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");
    }
}

RunListener的实施如下

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。
