gauge_maven_selenium project is erroring out when enable_multithreading is set to true

manavghaigit opened this issue · comments

commented

I am trying to run tests in parallel and it works fine as long as enable_multithreading is set to false. But the moment i set it to true, only one browser opens and gauge starts reporting errors during execution.

  1. Create a new project gauge_maven_selenium from vscode
  2. Create two different specs with some scenarios in it (Note: In my case i just copied example.spec to create example1.spec which has same scenarios)
  3. Set enable_multithreading to true in default.properties
  4. Run the command in Terminal - mvn gauge:execute -DspecsDir=specs -DinParallel=true -Dnodes=3
  5. Below is the output with error details

is written to be used without multi threading. You will need to modify the code to make it thread safe. You can try asking this at https://spectrum.chat/gauge as there are other people who could share how they run it in a thread safe manner.

@zabil Thanks for your quick response. I have 2 CPU's with each one having 1 core so total 2 cores. Considering same i am running below scenarios. Are they as expected? Please advise.

I have 6 spec files with one scenario in each spec file and multi threading is turned off:

  1. With command "mvn gauge:execute -DspecsDir=specs -DinParallel=true" wherein nodes are not mentioned, it runs on two steams as i have two cores. I am assuming this is correct?

  2. With command "mvn gauge:execute -DspecsDir=specs -DinParallel=true -Dnodes=6" wherein i have mentioned nodes to be 6, it is actually opening 6 different streams. Is this how it should be? I thought it should not go beyond 2 streams as i have only 2 cores in my system. Please advise.

There is info about this here https://docs.gauge.org/execution.html?os=macos&language=python&ide=vscode#parallel-execution

Also mentioned there is

It could lead to undesirable results if the number of streams specified is more than the number of CPU cores available on your system.

@zabil thanks for your response. Yes i did look at the documentation before sending a message, but because it is behaving differently than what is mentioned in the documentation so thought of clarifying with you. It would be helpful if you can look at below points 1 and 2 and provide your inputs.

Yes

Yes, it will try to the number of streams mentioned in the nodes=6 parameter, however this is unpredicatable as the number of streams should not be more than the number of cores. Nodes can be used rather for not defaulting to use all the cores in a paraller run (for example use 2 out of 4 cores)

@zabil Thanks Zabil got it.
