Selenium Grid并行运行测试 [英] Selenium Grid running tests in parallel
问题描述
当前，我有一个Selenium网格设置，具有1个本地集线器和2个本地节点.集线器能够分发并行运行的测试，并将其分发到节点.我正在并行运行测试.
Currently, I have a Selenium grid setup, with 1 local hub and 2 local nodes. The hub is capable of distributing the tests to run in parallel and distribute it over to the nodes. I am running the tests in parallel.
以下是基础测试
public abstract class BaseTest
{
String testFolder;
String testName;
protected String envName;
protected Configuration config;
protected String host;
protected RemoteWebDriver driver;
protected String proxy;
protected SomeData someData;
protected SomeController someController;
public BaseTest() {
}
public BaseTest( String testFolder, String testName)
{
this.testFolder = testFolder;
this.testName = testName;
this.envName = System.getProperty("config");
this.proxy = System.getProperty("proxy");
config = this.envName;
}
@BeforeMethod
public void startTest(Method testMethod) {
LOG.info("Starting test: " + testMethod.getName());
try {
this.someData = new SomeData();
this.driver = WebDriverSetup.getDriver();
this.someController = new someController(this.driver, this.someData);
driver.navigate().to("https://" + this.host);
} catch (MalformedURLException e) {
System.out.println("MalformedURLException");
}
}
@AfterMethod
public void closeWindow() {
driver.close();
driver.quit();
}
}
以下是获取RemoteWebDriver的类:
The following is the class to get the RemoteWebDriver:
public class WebDriverSetup {
public static RemoteWebDriver getDriver() throws MalformedURLException{
String SELENIUM_HUB_URL = "http://localhost:4444/wd/hub";
ThreadLocal<RemoteWebDriver> remoteWebDriver = null;
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
String proxy = System.getProperty("proxy");
if (proxy != null && !proxy.isEmpty()) {
System.out.println("Using proxy: " + proxy);
capabilities.setCapability(CapabilityType.PROXY, proxy);
}
try {
remoteWebDriver = new ThreadLocal<RemoteWebDriver>();
remoteWebDriver.set(new RemoteWebDriver(new URL(SELENIUM_HUB_URL),
capabilities));
} catch (MalformedURLException e) {
System.out.println("Tackle Issue with RemoteDriverSetup");
}
remoteWebDriver.get().manage().window()
.setSize(new Dimension(2880, 1524));
remoteWebDriver.get().manage().timeouts()
.pageLoadTimeout(10, TimeUnit.SECONDS);
remoteWebDriver.get().manage().timeouts()
.implicitlyWait(10, TimeUnit.SECONDS);
return remoteWebDriver.get();
}
}
我的测试套件就像:
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="Multiple Tests Suite" verbose="1" parallel="methods">
<test name="Test1">
<classes>
<class name="com.itesteverything.qa.Tests"></class>
</classes>
</test>
</suite>
测试就像:
public class Tests extends BaseTest {
@Parameters({"testName", "env" })
public Tests( @Optional String testName, @Optional String env ) {
super( null, testName, null, env );
}
@BeforeMethod
public void setup() throws Exception {
//setSomeData
}
public void test1() throws Exception {
use driver from super
use someData from super
use someController is using the driver from super
}
public void test2() throws Exception {
use driver from super
use someData from super
use someController is using the driver from super
}
在运行这些测试时，出现以下错误
While running these tests, I get the following errors

有人知道吗?
提前谢谢！
推荐答案
不要在基类中设置驱动程序，根本没有驱动程序属性.相同的实例被不同的线程本地驱动程序覆盖.
Do not set driver in the base class, do not have driver property at all. The same instance is being overridden by different threadlocal drivers.
每次您要运行测试时，请在测试方法本身以及after/before方法中参考WebDriverSetup.getDriver().
Any time you want to run your test, refer to WebDriverSetup.getDriver() in your test method itself and in your after/before methods.
