-HTML5 Media Performance/Functional Test |
-======================================= |
- |
-Description |
------------ |
-This directory contains suites for HTML5 media performance/functional tests. |
- |
-media_test_runner.py is the main module and it executes a media test |
-class (a subclass of MediaTastBase class) with different configuration |
-(parameters) which are passed in the form of environment variables |
-(e.g., the number of runs). The location of the subclass is passed as |
-one of the arguments. |
- |
-An example invocation is |
- python media_test_runner.py -p ./media_perf.py |
- |
-In this example, media_perf.py will be invoked using the default set |
-of parameters. If the test class is not specified in the argument, |
-whole AVPERF suite is executed, which is defined in |
-src/chrome/test/functional/PYAUTO_TESTS. |
- |
-To Run Tests |
------------- |
-0) Build pyauto (http://www.chromium.org/developers/testing/pyauto) |
- |
-1) Add the following in the .gclient and execute "gclient sync". This step is |
-necessary to pull the test video/audio from deps. |
- |
-"custom_deps" : { |
- "src/chrome/test/data/media/avperf": |
- "http://src.chromium.org/svn/trunk/deps/avperf", |
-}, |
- |
-2) Execute "python media_test_runner.py" from "src/chrome/test/functional" |
-directory. Available options can be obtained by "media_test_runner.py -h" |
- |
-3) The results are reported to the standard output. An example output is |
- |
-RESULT time: t= [0.01182, 0.00995, 2.02328, 2.02021] sec |
-RESULT procutil: p= [14.10000, 15.20000, 9.10000, 9.00000] percent |
-RESULT procuser: l= [0.54000, 0.88000, 0.74000, 1.08000] load |
-RESULT procsystem: l= [0.06000, 0.11000, 0.09000, 0.13000] load |
-RESULT memoryrss: m= [34.74637, 35.27885, 34.46374, 35.60243] MB |
-RESULT memoryvms: m= [1001.08288, 1001.34502, 1001.08288, 1001.34502] MB |
-RESULT memoryutil: p= [0.87187, 0.88523, 0.86478, 0.89335] percent |
