Benchmark Runner

This is a script for automating the browser based benchmarks(e.g. Speedometer, JetStream)

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:
    • 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.
