how to run concurrent users using different browsers in selenium for LogIn script

Question

I have created login scripts using hub and nodes.

• execute command to start selenium server
• Started a Hub along with selenium server.
• Started multiple Nodes.
• Worked on scripts and run for Firefox.

But, what should I do to run login script for concurrent users using multiple browser ?

Answer 1

This load test article is a great walkthru for your scenario - http://www.mkyong.com/unittest/testng-selenium-load-testing-example/

Answer 2

You can checkout my sample test automation project for OrangHRM using Selenium

https://github.com/qamate/orangehrm-selenium-automation

Below is my TestNG.xml file

                </classes>
            </test>
             -->
</suite>

In the above example, you can see the way I am specifying different browser combinations for different tests as parameters. From your test class you can read these parameters.

E.g. See below class file.

package in.mayurshah.base;

import java.io.IOException;
import java.util.concurrent.TimeUnit;

import in.mayurshah.DTO.WebDriverConfig;
import in.mayurshah.util.Log;
import org.openqa.selenium.WebDriver;
import org.testng.ITestContext;
import org.testng.ITestResult;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.AfterSuite;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.BeforeSuite;
import org.testng.annotations.Optional;
import org.testng.annotations.Parameters;

import in.mayurshah.DTO.TestCase;

public abstract class BaseActions {
    protected WebDriver driver;
    protected static Log log;
    protected WebDriverConfig config;
    protected String baseURL;
    protected TestCase testCase;
    private static int testCaseCount = 1;

    /**
     * This gets invoked even before suite starts.
     * @param ReportLocation - Provide location where you want to store the report
     */
    @Parameters({"ReportLocation"})
    @BeforeSuite
    public void beforeSuite(@Optional String ReportLocation){
        log = new Log();
        log.setReportDirectory(ReportLocation);
    }
    @BeforeMethod
    @Parameters({ "remoteURL", "baseURL", "OS", "browser",
            "version", "internal" })
    public void beforeTest(String remoteURL, String baseURL,
            String OS, String browser, String version, String internal)
            throws IOException {
        this.testCase = new TestCase();
        this.testCase.setExecutionEnvironment("{browser:"+browser+",browserVersion:"+version+",OperatingSystem:"+OS+"}");
        this.testCase.setParentURL(baseURL);
        this.testCase.setTestCaseId("KT"+testCaseCount++);
        this.testCase.setScreenshotDirectory(log.getReportDirectory()+"\\images");
        config = new WebDriverConfig();
        config.setRemoteURL(remoteURL);
        this.baseURL = baseURL;
        config.setOS(OS);
        config.setBrowserName(browser);
        config.setBrowserVersion(version);
        config.setIntenal(Boolean.parseBoolean(internal));
        driver = xRemoteWebDriver.getInstance(config, log);
        driver.manage().window().maximize();
        driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
        driver.get(this.baseURL);
    }

    @AfterMethod
    public void afterTest(ITestResult itr) {
        testCase.setExecutionTime((itr.getEndMillis() - itr.getStartMillis()));
        testCase.setTestCaseName(itr.getName());
        log.addTestCase(testCase);
        try {
            driver.close();
        } catch (Exception ignore) {

        }
        try {
            driver.quit();
        } catch (Exception ignore) {

        }
    }
    @AfterSuite
    public void afterSuite(ITestContext itc) throws IOException{
        log.setTestSuiteName(itc.getSuite().getName());
        log.writeReport();
        log.zipAndEmailFile();
    }

}

Hope that helps!
