Issue running Gauge Tests in Parallel

[harimadusumilli]

Running Parallel Tests in Gauge using Selenium seems to execute in series although browser launches in parallel.

environment : Windows 10 & Ubuntu Linux container too.

Gauge version: 1.1.8
Commit Hash: b1501f4

Plugins

dotnet (0.4.1)
html-report (4.0.12)
js (2.3.15)
json-report (0.3.5)
screenshot (0.0.1)
xml-report (0.2.3)

In the default. properties file we have also added the following entry:
enable_multithreading = true

Three spec files
We are running three spec files which contain the same navigation steps.
and are running them as below:

gauge run specs -p -n=4 --verbose

We are using static webdriver instance, this appears to conflict and creates in consistency while running it. The behavior appears to be erratic, for e.g:, we notice that the data is input incorrectly to a test case as the web driver appears to be key in the test data into only the browser it has a handle instead of their respective browser instances.

Code is as below:

using System;
using System.Collections.Generic;
using System.Linq;
using FluentAssertions;
using Gauge.CSharp.Lib;
using Gauge.CSharp.Lib.Attribute;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using System.Threading;

namespace DefaultProj
{
public class StepImplementation
{

    //This is the static webdriver

private static IWebDriver seleniumDriver;

    public void initWebDriver(){
        seleniumDriver = new ChromeDriver(Environment.CurrentDirectory + "/Selenium Drivers");
        ((IJavaScriptExecutor)seleniumDriver).ExecuteScript("window.focus();");
        seleniumDriver.Manage().Window.Maximize();
    }

    public void LaunchApp(){
        seleniumDriver.Navigate().GoToUrl("https://our_intranet_app.net/");
    }

    
    [Step("search with name <name>")]

public void SearchWithName(string name)
{
try{
this.initWebDriver();
this.LaunchApp();

seleniumDriver.FindElement(By.Id("search-inside-textbox")).SendKeys(name);
  
seleniumDriver.FindElement(By.XPath("//span[@class='icon icon-search']")).Click();

GaugeMessages.WriteMessage("Name search");
GaugeScreenshots.Capture(); 
seleniumDriver.Close();
}
catch(Exception e){
    Console.WriteLine(e.Message);
    seleniumDriver.Close();
}

}

}

}

checking into see if anyone from Gauge Support can comment on this or suggest.

Static variables do not fare well in multithreaded parallel execution. You may need to use an alternate pattern, for instance you may want to try using ThreadLocal<IWebDriver> instead of IWebDriver.

Note that static variables are shared between all threads in a process, hence there will be no isolation between gauge execution streams.

Thank you Sriv. We will try and see as per your suggestion if we can get this going by changing the pattern as advised.

hello @harimadusumilli, I know it's been a while since this discussion happened but I was wondering if you found a fix and what it was. We're having similar issues where the tests are running in Windows correctly but not working in Linux at all.
