Grid Execution and Session Queuing

Opkey Web is now integrated with an advanced feature called Grid Execution. With this feature, users can execute (or queue) multiple suites at a time. Here, the user can either choose an agent on which he wants to execute his run or leave the agent field blank.

Opkey Hub:

Opkey Hub is a utility that allows you to execute multiple Suites parallel through Grid Execution with the help of Opkey Execution Agent. All the sessions to be executed from Grid, come in a queue in Opkey Hub and then Hub will start the execution immediately depending upon the availability of the agent. As soon as the Opkey Agent has finished the execution of the current session, it picks up the next Queued session and the process continues until the queue gets empty.

There are a few necessary settings that are required for Grid Execution. Let us apply those settings from Opkey Agent.

Open Opkey Agent and switch to Web mode.
Fill all required fields and login with valid credentials.
Check Enable for Grid Execution checkbox.
Click on Save to save the made changes.
A popup message appears to relaunch the Agent and reflect the changes. Relaunch the Agent.

There are some Project Level Settings for Grid Execution feature that can be applied from the Project Management section in Admin.

Under the Admin section and click on the Project Management tab.

Click on the Update Project icon of the respective project to update the project for Grid Execution. Navigate to the Queued session settings and edit the number of maximum parallel runs allowed and maximum parallel runs allowed on BrowserStack. Maximum parallel runs allowed on BrowserStack should not be greater than the maximum parallel runs allowed.

Click on the Update Project icon to update the project for Grid Execution. Navigate to the Queued session settings and edit the number of maximum parallel runs allowed, maximum parallel runs allowed on BrowserStack and maximum parallel runs allowed on SauceLabs as per your requirement.

The Sessions displayed in the above window get executed one by one on the available agent. As soon as the Opkey agent has finished executing the current session, it picks up the next Queued session and the process continues until its queue is empty.

Suppose you want to run a Test Case/Function Library/Sparkin/Gherkin but no agent is available then that execution will gets added in the Queued session list.
