Sharded Playwright Example

info

This Workflows functionality is not available when running the Testkube Agent in Standalone Mode - Read More

Testkube has built-in support for parallelizing any testing tool - check out the Parallelization documentation for details and examples.

The below example shows how to distribute ("shard") a set of Playwright tests across a configurable number of nodes and aggregate individual reports into a single report that is available as an artifact.

The example below:

• Load the Git repository with Playwright test (content)
• Install the project dependencies (steps[0].shell)
• Run the Playwright tests split to 2 shards (steps[1].parallel)
  • Reserve 1 CPU and 1GB RAM for each shard (steps[1].parallel.container.resources)
  • Copy the repository and node_modules inside (steps[1].parallel.transfer)
  • Run Playwright test - with blob reporter, and with specific shard segment (steps[1].parallel.shell)
  • Fetch the Blob reporter's data to corresponding directory on Execution's pod (steps[1].parallel.fetch)
• Merge the reports using Playwright's tooling (steps[2].shell)
• Save the merged report as an artifact (steps[2].artifacts)
