An element to help performance test other elements.
The perf-tester element accepts an array of tests which are html files containing perf tests to run. A simple "runner.html" as is shown in /demo can be created to display output.
Each test file should load perf.js and call console.perf() to start the test and console.perfEnd() to finish it.
Run the node-script with
node node-perf-tester.js
The available options are:
--runs Number of runs to measure on
--targets The file location of a JSON-structured file with the following format:
[
["<type>", "<url>"]
]
where type is the name of the type you are testing and the url the location of the target under test
--port The port number to connect the protocol to. Use this when you are connecting to a separate device. If this argument is not provided, chrome-headless is used.
--throttling one of [FAST_3G, SLOW_3G] If not running in Chrome headless, you can enable throttling with one of the two options.
