Does testContext get shared between parallel test threads?

[deepng]

Hi

I am planning to run my tests in parallel. 

Say I want to login as a user but want to login as 3 different users in different threads and run through the same tests for these users. 

I am using TestContext to hold the various entities related to the user session between different testMethods. 

I am wondering if the testContext is shared between the various threads here?

ITestContext is shared by one or more @Test methods that are part of the same <test> tag.

Thanks & Regards

Hi

i am doing a similar kind of thing but while running test cases in parallel my execution fails

what i am doing is as an example

i have BaseTest class which sets itestcontext.setattribute("driver",new chromedriver()) under beforeemethod and in aftermethod i remove that attribute , however in testclasses i have multiple tests and i am using webdriver by taking it from like 

@test()

public void test1(itestcontext itestcontext){

webdriver driver = (webdriver)itestcontext.getattribute("driver");

//and subsequently using it in my page object classes

}

@test()

public void test2(itestcontext itestcontext){

webdriver driver = (webdriver)itestcontext.getattribute("driver");

//and subsequently using it in my page object classes

}

@test()

public void test3(itestcontext itestcontext){

webdriver driver = (webdriver)itestcontext.getattribute("driver");

//and subsequently using it in my page object classes

}

my test cases are running fine in serial order , but while parallel execution, it fails and getting error like sessionnotfound, or unable to connect webdriverexception. could you please help me out on this.

The basic problem with your code is that you are trying to create a WebDriver instance in a BeforeMethod and then trying to share that with a "@Test" method via ITestContext.

ITestContext represents a "<test>". So it is common for all "@Test" methods that are found within the same "<test>" tag.

So when you run your "@Test" methods in parallel, you are basically causing "@Test" methods to try and share the same "WebDriver" instance since it's being written into the same "ITestContext". That is why you are having problems with your concurrent executions.

I would suggest that you rethink your approach.

Sometime back I built an annotation driven approach that is thread safe and lets you share a WebDriver instance cleanly.

You can take a look at it here: https://github.com/rationaleemotions/autospawn 

The other option would be for you to leverage a ThreadLocal variant of managing webdrivers.

I have detailed the approach in this blog post of mine : https://rationaleemotions.com/parallel_webdriver_executions_using_testng/
