iBazel Benchmark Runner

This script runs iBazel on a specified target with the iBazel profiler enabled. After the initial build completes, it modifies a specified file by adding a newline to the end of it. The script reports the initial build time and the incremental build RTT.

It can also optionally launch chrome to a specified URL and report on the browser load RTT if the target (such as ts_devserver) serves a website.

Reporting

The scripts outputs the RTT in ms as follows:

[ibazel-benchmark-runner] Initial build time 24059ms
[ibazel-benchmark-runner] Incremental build RTT 4192ms
[ibazel-benchmark-runner] Browser load RTT 4402ms

Usage

node_modules/.bin/ibazel-benchmark-runner <run_target> <file_to_modify> [--url=<url>] [--initial_timeout=<seconds>] [--incremental_timeout=<seconds>]

Argument	Description
`run_target`	The bazel target to run.
`file_to_modify`	The file to modify in order to start in incremental build (a newline will be added to the end of this file).
`url`	Url for the benchmark to navigate to in order to measure browser interactive RTT for incremental build (optional).
`initial_timeout`	Maximum time to wait for the initial build (defaults to 300 seconds).
`incremental_timeout`	Maximum time to wait for the incremental build (defaults to 60 seconds).
`browser_timeout`	Maximum time to wait for browser page load event (defaults to 60 seconds).

For example:

node_modules/.bin/ibazel-benchmark-runner //src:devserver src/foo/bar.ts --url=http://localhost:5432
