Using Webdriver to collect Navigation Timing.
Travis job runs / Build #51 / JSON output
Usage: sauce-browsertime [options] [urls, ...]
$ sauce-browsertime http://example.com -b firefox -n 3 --assert-pageload-max=5000 --assert-frontend-p90=2500
See https://saucelabs.com/platforms for the list of available OS / Browser / Version
Options:
-b, --browser - Saucelabs browser (default: chrome)
-p, --platform - Saucelabs platform (default: unspecified)
-t, --type - Saucelabs device type (default: unspecified)
-o, --orientation - Saucelabs device orientation (default: unspecified)

-h, --help
Asserts:
--assert-name-stat=[value] - Specify a test assertion on [name] metric
--assert-name=value - Specify a test assertion on [name] average value
Available stats: min, max, avg, media, mad, p60, p70, p80, p90Every webdriver enabled browser on Saucelabs, implementing Navigation Timing API should be supported.
Install
$ npm install saucelabs-browsertime -g
# local
$ npm install saucelabs-browsertime
node_modules/.bin/sauce-browsertime -hAsserts
--assert-* params sets up test assertion on a specific interval and stat.
Stats are based on https://github.com/tmcw/simple-statistics. Use the -n, --runs option to set the number of pageload per URL.

list - spec-style listing
tap - test-anything-protocol
landing - unicode landing strip

Not a a mocha reporter per say. Transforms the raw JSON data of a previous run into an HTML page, with visual representation of the Timing objects thanks to http://kaaes.github.io/timing/
Usage: sauce-browsertime-html [options] file.json
$ sauce-browsertime results.json > index.html
Graphs generated thanks to http://kaaes.github.io/timing/
Browser logos thanks to https://github.com/alrra/browser-logos
Options:
-b, --browser - Browser under test (used to match browser logo)Jenkins template
config.xml file is a Jenkins Job template that can be used to quickly
setup a Job to run the perf test, at a fixed interval or on SCM change:
Includes Job parameters for:
PERF_URLS: List of URLs to test. Whitespace separated.SAUCE_USERNAME: Saucelabs usernameSAUCE_ACCESS_KEY: Saucelabs API keySAUCE_BROWSERS: Comma separated list of browsers.
Shell scripts
- Install npm packages on first run (npm install saucelabs-browsertime)
- A run for each browser, stats & raw metrics available at
./results/BUILD_NUMBER/BROWSER/metrics.json, HTML report at./results/BUILD_NUMBER/BROWSER/metrics.json.
Plugin configuration for htmlpublisher (optional to have it installed, jenkins will just ignore the conf)
See config.xml file for further detail.
