一个测试观察器,用于报告JUnit Suite中各个测试的结果

Question

所以我有一个套件,如下所示:

@RunWith(Suite.class)
@Suite.SuiteClasses({TestClass1.class, TestClass2.class, TestClass3.class})
public class TestSuite {

    static List<ExtentTest> extentTestList = new ArrayList<>();

    @ClassRule
    public static ExtentWatcher extentWatcher = new ExtentWatcher() {
        @Override
        protected void starting(Description description) {
            extentTestList.addAll(extentWatcher.getTests());
        }
        @Override
        protected void finished(Description description) {
            extentWatcher.flushReports(extentTestList);
        }
    };
}

上面的代码有效,但问题是它导致我的Watcher报告套件的结果,而不是单独的测试.此外,如果测试失败,套件仍会报告为已通过.我的看守器是这样的:

public class ExtentWatcher extends TestWatcher {

    // A little set up to give the report a date in the file name
    private DateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy");
    private Date date = new Date();
    private String fileDate = dateFormat.format(date);
    private String reportName = "./Test_Report_" + fileDate + ".html";
    public ExtentReports extent;
    ArrayList<ExtentTest> testList = new ArrayList<>();

    public ExtentWatcher() {
        extent = createReport();
    }

        // If test passed, watcher will record this with Extent Reports
        @Override
        protected void succeeded(Description description) {
            ExtentTest test = extent.startTest(description.getDisplayName());
            test.log(LogStatus.PASS, "Test Run Successful");
            testList.add(test);
        }

        // Likewise in case of failure
        @Override
        protected void failed(Throwable e, Description description) {
            ExtentTest test = extent.startTest(description.getDisplayName());
            test.log(LogStatus.FAIL, "Test Failure: " + e.toString());
            testList.add(test);
        }

    /**
     * These methods do the legwork - this file is based off of an example I found @ www.kieftsoft.nl/?p=81
     * Eventually we can add some screenshot logic here, but just a clean test report and version info will do
     */

    private ExtentReports createReport() {
        // Create the report - Extent just needs a little config
        ExtentReports extent = new ExtentReports(reportName, false);
        extent.config().reportName("Test Report: " + fileDate);
        return extent;
    }

    public void flushReports(List<ExtentTest> testList) {
        // This ends the test and then sends (flushes) everything to the html document
        for(ExtentTest test : testList) extent.endTest(test);
        extent.flush();
    }

    public List<ExtentTest> getTests() {
        return testList;
    }
}

对于单个测试,此代码可以很好地注释为@Rule(每个测试都有一个单独的报告,不可取),但是如上所述,这不适用于套件级别,我真的不知道如何制作它工作.我以为我可以收集所有测试的列表,并在套件中结束测试并刷新它们,这将允许ExtentReport给我一份所有测试的报告.但是,我无法专门获得单独的测试结果 - 我将返回一个测试,displayName()=套件名称.

如何跟踪各个测试,然后在完成所有测试后将它们清除,让ExtentWatcher在测试的基础上处理测试的通过/失败,而不仅仅是套件的一次？

我使用 RunListener 实现，它将结果记录在文件中。首先，我有一个为每个测试套件调用的测试运行程序类：

public Result run(String suite) {
    Class<?> suiteClass = null;
    try {
      suiteClass = Class.forName(suite);
    } catch (ClassNotFoundException ex) {
      return null;
    }
    JUnitCore core = new JUnitCore();
    this.testRun = new TestRun(testLogging, suite);
    core.addListener(new TestRunListener(testLogging, testRun));
    Result result = core.run(suiteClass);
    return(result);
}

TestRun 类是一个自定义类，它只计算已启动、通过、失败、忽略的测试数量。

TestRunListener 实现 org.junit.runner.notification.RunListener，并根据回调（例如 testFailure()、testFinished() 等）跟踪有关测试状态的信息。

@Override
public void testFailure(Failure failure) throws Exception {
  classLogger.log(Level.CONFIG, failure.getMessage());
  classLogger.log(Level.CONFIG, failure.getTestHeader());
  classLogger.log(Level.CONFIG, failure.getTrace());
  classLogger.log(Level.CONFIG, failure.getDescription().getDisplayName());
  if (failure.getException() != null) {
    classLogger.log(Level.CONFIG, failure.getException().getMessage());
  }
  super.testFailure(failure);

  Description description = failure.getDescription();
  Test test = processTestResult(TestStatus.FAIL, description);
  if (test == null) {
    classLogger.log(Level.SEVERE, "TEST IS NULL:" + description.getDisplayName());
    return;
  }

  classLogger.log(Level.CONFIG, failure.getMessage()+ " " + description.getDisplayName());

  test.setFailureMessage(description.getDisplayName());
  test.setFailureException(failure.getException());
  LogRecord record = new LogRecord(Level.CONFIG, failure.getMessage());
  record.setParameters(new Object[] { test, failure });
  testFailuresLogger.log(record);
}
