Run Benchmarks ⏱️

A Github Action that runs your Android microbenchmarks in Firebase Test Labs and optionally:

• updates a GitHub issue with the latest benchmark results (see here for a sample issue)
• publishes the metrics to Datadog (see here for a sample dashboard)

See the action in action (ha ha!) at https://github.com/martinbonnin/run-benchmarks-sample

Note: Macrobenchmarks are not supported just yet

Datadog integration

If you specify dd_api_key, the metrics are uploaded to Datadog automatically. This action publishes 2 metrics:

• ${dd_metric_prefix}.allocs: the median number of allocations per test
• ${dd_metric_prefix}.nanos: the median number of nanosecond per test

Each metric is tagged with the class of the test and the name of the test. For an example:

• class:com.example.BenchmarkTest
• test:parseSomething
