如何在多个并行线程中运行单个 testng 测试用例

Question

我想在任何浏览器中多次并行运行单个测试 NG 测试用例

Answer 1

A.1. To run a test case multiple times use invocationCount attribute in @Test annotation. This invocationCount determines how many times TestNG should run this test method.

@Test(invocationCount = ?)

A.2. To run a test case mutiple times in different threads use threadPoolSize attribute in @Test annotation. This attribute tells TestNG to create a thread pool to run the test method via multiple threads

@Test(invocationCount = ?, threadPoolSize = ?)

B.3. To run a test case in multiple browsers in different threads initialize your webDriver as ThreadLocal

private static ThreadLocal<WebDriver> webDriver = new ThreadLocal<WebDriver>();

In testng.xml create tests with browser name as a parameter

<test name="Test">
    <parameter name="browserName" value="firefox"></parameter>
    <classes>
        <class name="MyTestCases" />
    </classes>
</test>

<test name="Test">
    <parameter name="browserName" value="Chrome"></parameter>
    <classes>
        <class name="MyTestCases" />
    </classes>
</test>

use @Parameters() to fetch the value of browser name

@BeforeTest
@Parameters("browserName")
public void webDriverHandler(String browserName){
  // String browserName contains parameter value
}

Create a Driver handler and a testbase classes. Use Driver handler to set and get webDriver and use your base class to fetch the browser name

Driver handler:

public class DriverHandler {

private static ThreadLocal<WebDriver> webDriver = new ThreadLocal<WebDriver>();

public static WebDriver getDriver() {
    return webDriver.get();
}

public static void setWebDriver(String browser) {

     WebDriver driver = null;

     if (browser.contains("firefox")) {

       driver = new FirefoxDriver();

    } else if (browser.contains("chrome")) {

       ChromeOptions options = new ChromeOptions();
       driver = new ChromeDriver(options);  

    }
    webDriver.set(driver);
}


}

testbase:

public class TestBase { 

 @BeforeTest
 @Parameters("browserName")
 public void threadHandler(String browserName) {

    Thread.currentThread().setName(browser.toLowerCase());
    if (DriverManager.getDriver() == null)
        DriverManager.setWebDriver(browser);
 }


}
