Methods in test in parallel way


Methods in test in parallel way

I think the issue was by ths following , I have to write test in java with selenium using eclipse. I have situation where i need to run simultaneously two browsers. I know there is TestNG, but for now i can't afford to use it. So my question is, is there a way to use , This can easily be done; for example by using anonymous innerclasses:
code :
Thread thread1 = new Thread( new Runnable() {
  @Override 
  public void run() {
  ... will happen in its own thread 
  }
});

will be helpful for those in need Unfortunately, webDriver is not thread-safe. Imho, best practice is to run each test class using individual webDriver instance in separate thread. The optimal number of threads is int threadNum = Runtime.getRuntime().availableProcessors() * 2; The executing time of my projects reduced from 30 minutes to 4. Exactly the same method is used in Thucydides framework.

wish of those help Split the test into two sections.
Test the process up to the point you would wait for input.
code :
def self.create_and_wait_on_record(msg)
  rec = create(question: msg)

  wait_and_process(rec)     
end
it 'Creates the record and continues processing when capable' do 
  subject.should_receive(:wait_and_process).with(stub_rec)
  subject.create_and_wait_on_record(mock_msg)
end
it 'Processes a record once it has been created and has had the requisite data populated' do 
   subject.stub(:create).and_return(mock_created_record)
   subject.create_and_wait_on_record(mock_msg)
end

will be helpful for those in need Here are some ways of doing this in TestNG. You basically manage your webdriver instantiation and cleanup via a @BeforeMethod and a @AfterMethod config methods. So then you would need to decide how would you want to share the created webdriver instance with your @Test method. For that you have three options:
You make use of a ThreadLocal variant, because TestNG guarantees to you that it will execute @BeforeMethod, @Test and @AfterMethod all in the same thread.
code :
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.testng.ITestResult;
import org.testng.Reporter;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;

public class TestClassSampleUsingThreadLocal {
    private static final ThreadLocal<RemoteWebDriver> drivers = new ThreadLocal<>();

    @BeforeMethod
    public void instantiateBrowser(ITestResult testResult) {
        RemoteWebDriver driver = new ChromeDriver();
        drivers.set(driver);
    }

    @Test(dataProvider = "dp")
    public void testMethod(String url) {
        Reporter.log("Launching the URL [" + url + "] on Thread [" + Thread.currentThread().getId() + "]", true);
        driver().get(url);
        Reporter.log("Page Title :" + driver().getTitle(), true);
    }

    @DataProvider(name = "dp", parallel = true)
    public Object[][] getData() {
        return new Object[][]{
                {"http://www.google.com"}, {"http://www.stackoverflow.com"}, {"http://facebook.com"}
        };
    }

    @AfterMethod
    public void cleanupBrowser() {
        RemoteWebDriver driver = driver();
        driver.quit();
    }

    private RemoteWebDriver driver() {
        RemoteWebDriver driver = drivers.get();
        if (driver == null) {
            throw new IllegalStateException("Driver should have not been null.");
        }
        return driver;
    }

hope this fix your issue You are storing the driver at class level. But you parallelise based on methods. In this case one driver object will be there. I see the thread local lines were commented.
There are two ways to solve this issue,
code :
        Webdriver driver = initDriver(browser);
        homeObject = new HomePage(driver, report, wait, logger);
        homeObject.goToHomepge(url);
 public class DriverCreation {
    private static ThreadLocal<WebDriver> WEBDRIVER = new ThreadLocal<WebDriver>();

   public WebDriver getWebDriver(String browser){
      WebDriver driver= WEBDRIVER.get();
      if (driver== null) {
        driver = initDriver(browser);
        WEBDRIVER.set(driver);
      }
      return driver;
   }

}
        Webdriver driver = getWebDriver(browser);
        homeObject = new HomePage(driver, report, wait, logger);
        homeObject.goToHomepge(url);

wish help you to fix your issue I have a large set of integration tests that test a website server. Most of these tests are fine to run in parallel. However, I have a few that change settings and can cause each other to fail when run in parallel. , MsTest v2 has functionality as following
code :
[assembly: Parallelize(Workers = 0, Scope = ExecutionScope.MethodLevel)]
// Notice the assembly bracket, this can be compatible or incompatible with how your code is built

namespace UnitTestProject1
{
    [TestClass]
    public class TestClass1
    {
        [TestMethod]
        [DoNotParallelize] // This test will not be run in parallel
        public void TestPrice_5PercentTax() => //YourTestHere?;

        [TestMethod]
        [DoNotParallelize] // This test will not be run in parallel
        public void TestPrice_10PercentTax() => //YourTestHere?;            

        [TestMethod]
        [DoNotParallelize] // This test will not be run in parallel
        public void TestPrice_NoTax() => //YourTestHere?;

        [TestMethod]
        public void TestInventory_Add10Items() => //YourTestHere?;

        [TestMethod]
        public void TestInventory_Remove10Items() => //YourTestHere?;
    }
}
