SeleniumGrid并行执行只在dockerchrome节点上运行少数测试用例

Question

现在我有80个使用数据提供程序的测试方法(@test(，我正在运行我的测试用例及其近400个测试用例。当我以硒网格并行方式运行它时，它只运行了几个测试用例。有时40有时50随机运行这是我的基本类

public class BaseTest {
private static final String OS = System.getProperty("os.name").toLowerCase();
public static boolean IS_WINDOWS = (OS.indexOf("win") >= 0);
public WebDriver driver;
String report = null;
public WebDriver getDriver() {
return driver;
}
@BeforeClass(alwaysRun = true)
public void classLevelSetup() throws InterruptedException {
//Did nothing
}
@BeforeMethod(alwaysRun = true)
public void methodLevelSetup() throws ParseException, MalformedURLException {
Log.info("Tests are starting!");
ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--disable-gpu");
chromeOptions.addArguments("--disable-extensions");
chromeOptions.addArguments("disable-infobars");
chromeOptions.addArguments("--disable-dev-shm-usage");
chromeOptions.addArguments("ignore-certificate-errors");
chromeOptions.setPageLoadStrategy(PageLoadStrategy.NORMAL);
chromeOptions.addArguments("--start-maximized");
driver=new RemoteWebDriver(new 
URL("http://localhost:4444/wd/hub"),chromeOptions);

// Added Browser
}
@AfterMethod(alwaysRun = true)
public void AfterMethod(ITestResult result, ITestContext ctx)
{
getTest().fail(result.getThrowable());

driver.quit();
}
@AfterClass(alwaysRun = true)
public void teardown() {
//Did nothing
}

这是我的测试课

public class DashboardTest extends BaseTest {
@DataProvider(name = "CreateProperty")
public Object[][] getData() {
Object[][] data = SiteConfig.CreateProperty;
return data;
}
@Test(priority = 0, alwaysRun = true, dataProvider = "CreateProperty", description = "Add new property from Management > Properties")
public void Add_new_Property_from_management_Properties(String url, String username, String password, Method method, ITestContext ctx) throws Exception {
SignupPage sp = new SignupPage(driver);
sp.Open_login_Page(url);

}

}

这是我的testng.xml文件

<?xml version="1.0" encoding="UTF-8"?>

<test name="CultBooking">
<classes>
<class name="tests.RoomTypeTest"></class>
<class name="tests.RoomTypeTest_1"></class>

<class name="tests.Reservation_processTest"></class>
<class name="tests.SignInTest"></class>
<class name="tests.DashboardTest"></class>
<class name="tests.ForgotPasswordTest"></class>
</classes>
</test>

有人能帮我解决这个问题吗

Answer 1

如果测试用例总数与预期不匹配，可能是因为某些testNG生命周期代码中出现异常。

首先，我说的是听众。

我在堆栈中看到utils.listeners.TestListener。

saveScreenshotPNG会产生一些异常。

确保它的所有方法都不会抛出任何异常。环绕try-catch中的所有代码，因为TestNG无法准确处理侦听器中的异常。

另一个问题是，为什么有时saveScreenshotPNG中会发生异常。但无论如何，请先尝试使utils.listeners.TestListener成为故障安全型。
