junit TestWatcher失敗並已完成方法開火時間

Question

我正在用webdriver編寫一些功能測試並使用JUnit執行它們。我正在嘗試使用TestWatcher類，因此每次發生事件時都可以執行特定的操作。我重寫完成和失敗的方法，但似乎是這些被幾乎同時觸發，所以在失敗的方法可以做到這一點之前，驅動程序已經被完成方法處理了。

的TestWatcher是以下幾點：

public class TestRules extends TestWatcher { 

private static WebDriver driver; 
private static final Logger Log = LogManager.getLogger(TestRules.class); 

public TestRules() { 
    if (driver == null) 
     try { 
      driver = TestHelpers.getWebDriver(); 
     } catch (Exception e) { 
      throw new RuntimeException(e); 
     } 
} 

@Override 
protected void starting(Description description){ 
    Log.info(String.format("Started test: %s::%s", description.getClassName(), description.getMethodName())); 
    try { 
     new LoginTest().testDoLogin(); 
    } catch (Exception e) { 
     Log.error(e); 
    } 
} 

@Override 
protected void failed(Throwable e, Description description) { 
    File scrFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE); 

    String path = String.format("C:\\localdev\\screenshot\\%d__%s_%s.png", 
      Calendar.getInstance().getTimeInMillis(), description.getClassName(), description.getMethodName()); 
    try { 
     FileUtils.copyFile(scrFile, new File(path)); 
    } catch (IOException ioe) { 
     Log.error(ioe); 
    } 
    Log.error(String.format("Error: %s\nScreenshot: %s", e.getMessage(), path)); 
} 

@Override 
protected void finished(Description description) { 
    Log.info(String.format("Finished test: %s::%s", description.getClassName(), description.getMethodName())); 
    try { 
     // This actually calling driver.quit() <- (driver == WebDriver) 
     TestHelpers.close(); 
    } catch (Exception e) { 
     Log.error(e); 
    } 
} 

} 

測試可能是這樣的：

public class testSomething { 
private static final Logger Log = LogManager.getLogger(testSomething.class); 

@Rule 
public TestRules testRules = new TestRules(); 

@Test 
public void filterTableByNameWildcard() throws Exception { 
    Log.info("Starting the test filterTable"); 

    MainView mainView = getMainView(); 
    String searchString = "A*"; 
    mainView.setFilterParametersAndDoFilter(searchString, "", true, true); 
    mainView.validateWildCardSearchReturnsCorrectData(searchString); 
    // Random failing point for testing 
    Assert.assertTrue(false); 

當我運行我的測試，我得到一個以下錯誤：

java.lang.AssertionError:

任何想法如何獲得通過它？

編輯： 從文檔：

保護無效成品（描述描述） 時調用的測試方法完成（是否通過或失敗的）

保護無效失敗（Throwable的E，說明描述） 調用當測試失敗時

這將是有道理的，首先調用「失敗」，然後調用「完成」，但似乎是另一種方式。

你的問題是一個共享資源，不是在每次執行時新鮮創建。我創建了一個小例子來展示這一點。看看my comment to your comment。
