Requirements

• python modules:
  • PyObjc
  • psutils (optional)

HOW TOs

### How to run

python path/to/run-benchmark --build-directory path/to/browser/directory --plan json_format_plan --platform target_platform --browser target_browser

• path/to/browser/directory: should be the folder containing the executable binary(e.g. /Application/ on OSX which contains Safari.app)
• json_format_plan: the benchmark plan you want to execute

How to create a plan

To create a plan, you may refer to Plans/jetstream.plan.

{
    "timeout" : 600,
    "count": 5,
    "local_copy": "../../../../PerformanceTests/JetStream",
    "benchmark_patch": "data/patches/JetStream.patch",
    "entry_point": "JetStream/JetStream-1.0.1/index.html",
    "config": {
        "orientation": "portrait"
    },
    "output_file": "jetstream.result"
}

Plan is a json-formatted dictionary which contains following keys

• timeout: time limit for EACH RUN of the benchmark. This can avoid program getting stuck in the extreme circumstances. The time limit is suggested to be 1.5-2x the time spent in a normal run.
• count: the number of times you want to run benchmark
• local_copy: (OPTIONAL) Path of benchmark, a relative path to the root of this project ('benchmark_runner' directory)
• remote_archive: (OPTIONAL) URL of the remote (http/https) ZIP file that contains the benchmark.
• benchmark_path: (OPTIONAL) path of patch, a relative path to the root of this project ('benchmark_runner' directory)
• entry_point: the relative url you want browser to launch (a relative path to the benchmark directory)
• config: a dictionary that specifies the environment configurations for the test (e.g. orientation while the test is running)
• output_file: specify the output file, this can be overwritten by specifying '–output-file' while invoking run-benchmark script

How to import a benchmark

• Modify the benchmark html file, make sure the page has following functionalities:
  • When you launch the page('entry_point' in benchmark), the test will start automatically
  • Organizing the results
  • 'POST' information to '/report', and 'GET' '/shutdown' when post succeeds. Example:
  • ```js var xhr = new XMLHttpRequest(); xhr.open("POST", "/report"); xhr.setRequestHeader("Content-type", "application/json"); xhr.setRequestHeader("Content-length", results.length); xhr.setRequestHeader("Connection", "close"); xhr.onreadystatechange = function() { if(xhr.readyState == 4 && xhr.status == 200) { var closeRequest = new XMLHttpRequest(); closeRequest.open("GET", '/shutdown'); closeRequest.send() } } xhr.send(results); ```
• Create a patch file against original file
  • Go to the directory contains the benchmark directory (e.g. for JetStream, you should go to PerformaceTest folder)
  • Use git diff --relative HEAD > your.patch to create your patch
  • (Suggested) move the patch to the 'Patches' directory under project directory
• Create a plan for the benchmark (refer to **"How to create a plan"** for more details)
• Do following instruction ONLY IF NEEDED. In most case, you do not have to.
  • If you want to customize BrowserDriver for specific browser/platform, you need to extend browser_driver/browser_driver.py and register your module in browser_driver/browser_driversjson.
  • If you want to customize HTTPServerDriver, you need to extend http_server_drirver/http_server_driver and register your module in http_server_driver/http_server_drivers.json.
