我需要一些帮助来解决问题，同时通过Saucelabs进行跨浏览器selenium java测试执行。我正在从Jenkins工作中选择的2个浏览器上运行一个测试。
执行一个测试时，另一个（类似的）因错误而失败：
似乎一个测试中断了另一个测试。两个测试都在自己的隧道和线程下运行。

问题在于您的测试代码。它肯定与你的@Test方法之间的竞争条件有关[你在你的parallel="true"注释和@DataProvider你有你的parallel="methods" ]
您需要重构代码，以便您的driver对象是线程安全的。
您可以使用以下方法执行以下操作：
ITestResult对象。下面的示例演示如何使用ThreadLocal变体来使代码线程安全
import java.net.URL;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.testng.ITestResult;
import org.testng.annotations.AfterMethod;
public class RemoteTestBase {
public static final ThreadLocal<RemoteWebDriver> driver = new ThreadLocal<>();
private static String baseUrl;
private static final String SAUCE_ACCESS_KEY = System.getenv("SAUCE_ACCESS_KEY");
private static final String SAUCE_USERNAME = System.getenv("SAUCE_USERNAME");
void createRemoteDriver(String browser, String version, String os, String methodName)
throws Exception {
DesiredCapabilities capabilities = new DesiredCapabilities();
Class<? extends RemoteTestBase> SLclass = this.getClass();
capabilities.setCapability("browserName", browser);
if (version != null) {
capabilities.setCapability("browser-version", version);
}
capabilities.setCapability("platform", os);
capabilities.setCapability("name", SLclass.getSimpleName());
capabilities.setCapability("tunnelIdentifier", "***");
URL url = new URL(
"http://" +
SAUCE_USERNAME + ":" +
SAUCE_ACCESS_KEY + "@ondemand.saucelabs.com:80/wd/hub");
RemoteWebDriver rwd = new RemoteWebDriver(url, capabilities);
driver.set(rwd);
getURL();
}
protected static RemoteWebDriver getDriver() {
return driver.get();
}
private void getURL() {
getDriver().get(baseUrl);
getDriver().manage().timeouts().implicitlyWait(40, TimeUnit.SECONDS);
this.annotate("Visiting HDSupply page..." + driver.toString());
}
private void printSessionId() {
String message = String.format("SauceOnDemandSessionID=%1$s job-name=%2$s",
getDriver().getSessionId(), "some job name");
System.out.println(message);
}
@AfterMethod(description = "Throw the test execution results into saucelabs")
public void tearDown(ITestResult result) {
String txt = "sauce:job-result=" + (result.isSuccess() ? "passed" : "failed");
getDriver().executeScript(txt);
printSessionId();
getDriver().quit();
}
void annotate(String text) {
getDriver().executeScript("sauce:context=" + text);
}
}
您的所有子类都将尝试通过RemoteWebDriver方法访问getDriver()对象。
需要注意的是，你的@BeforeMethod需要调用createRemoteDriver()，以便RemoteWebDriver对象被实例化并推入ThreadLocal上下文，该上下文将是有效的并且可以在@Test方法中访问。
规则总是@BeforeMethod（驱动程序实例化发生）> @Test（驱动程序被消耗> @AfterMethod（驱动程序清理应该发生）。这是唯一的组合，其中RemoteWebDriver对象在ThreadLocal上下文中有效。
