Crossbench

Crossbench is a cross-browser/cross-benchmark runner to extract performance numbers.

This project uses poetry deps and package scripts to setup the correct environment for testing and debugging.

pip3 install poetry

Example usage:

poetry run crossbench speedometer_2.0 \
    --browser=/path/to/chromium \
    --stories=VanillaJS.* \
    --probe=profiling \
    --probe=v8.log

Describe all subcommands with stories and all probes:

poetry run crossbench describe

Main Components

Browsers : Interface to start, interact and stop browsers. The main implementions use selenium for maximum system independence.

Probes : Probes define a way to extract arbitrary (performance) numbers from a host or running browser. This can reach from running simple JS-snippets to extract page-specific numbers to system-wide profiling.

Stories : Stories define sequences of browser interactions. This can be simply loading a URL and waiting for a given period of time, or in more complex scenarios, actively interact with a page and navigate multiple times.
