Brian Sheedy 17b1a45253 Split large CTS logs 
Updates the CTS test runner JS to split logs into multiple
pieces if they're in danger of running into the payload
size limit that the test harness has.

crrev.com/c/3584705 must land in Chromium first.

Bug: chromium:1315658

Running the WebGPU CTS Locally with Chrome

Running the WebGPU CTS locally with Chrome requires a Chromium checkout.

Follow these instructions for checking out and building Chrome. You'll also need to build the telemetry_gpu_integration_test target.

At the root of a Chromium checkout, run: ./content/test/gpu/run_gpu_integration_test.py webgpu_cts --browser=exact --browser-executable=path/to/your/chrome-executable

If you don't want to build Chrome, you can still run the CTS, by passing the path to an existing Chrome executable to the --browser-executable argument. You should still build the telemetry_gpu_integration_test target to support all harness functionality.

Useful command-line arguments:

  • -l: List all tests that would be run.
  • --test-filter: Filter tests. Run --help for more information.
  • --help: See more options.
  • --passthrough --show-stdout: Show browser output. See also --browser-logging-verbosity.
  • --extra-browser-args: Pass extra args to the browser executable.
  • --is-backend-validation: Enable backend validation. TODO: rename this to --backend-validation.
