| 1 HTML5 Media Performance/Functional Test | |
| 2 ======================================= | |
| 3 | |
| 4 Description | |
| 5 ----------- | |
| 6 This directory contains suites for HTML5 media performance/functional tests. | |
| 7 | |
| 8 media_test_runner.py is the main module and it executes a media test | |
| 9 class (a subclass of MediaTastBase class) with different configuration | |
| 10 (parameters) which are passed in the form of environment variables | |
| 11 (e.g., the number of runs). The location of the subclass is passed as | |
| 12 one of the arguments. | |
| 13 | |
| 14 An example invocation is | |
| 15 python media_test_runner.py -p ./media_perf.py | |
| 16 | |
| 17 In this example, media_perf.py will be invoked using the default set | |
| 18 of parameters. If the test class is not specified in the argument, | |
| 19 whole AVPERF suite is executed, which is defined in | |
| 20 src/chrome/test/functional/PYAUTO_TESTS. | |
| 21 | |
| 22 To Run Tests | |
| 23 ------------ | |
| 24 0) Build pyauto (http://www.chromium.org/developers/testing/pyauto) | |
| 25 | |
| 26 1) Add the following in the .gclient and execute "gclient sync". This step is | |
| 27 necessary to pull the test video/audio from deps. | |
| 28 | |
| 29 "custom_deps" : { | |
| 30 "src/chrome/test/data/media/avperf": | |
| 31 "http://src.chromium.org/svn/trunk/deps/avperf", | |
| 32 }, | |
| 33 | |
| 34 2) Execute "python media_test_runner.py" from "src/chrome/test/functional" | |
| 35 directory. Available options can be obtained by "media_test_runner.py -h" | |
| 36 | |
| 37 3) The results are reported to the standard output. An example output is | |
| 38 | |
| 39 RESULT time: t= [0.01182, 0.00995, 2.02328, 2.02021] sec | |
| 40 RESULT procutil: p= [14.10000, 15.20000, 9.10000, 9.00000] percent | |
| 41 RESULT procuser: l= [0.54000, 0.88000, 0.74000, 1.08000] load | |
| 42 RESULT procsystem: l= [0.06000, 0.11000, 0.09000, 0.13000] load | |
| 43 RESULT memoryrss: m= [34.74637, 35.27885, 34.46374, 35.60243] MB | |
| 44 RESULT memoryvms: m= [1001.08288, 1001.34502, 1001.08288, 1001.34502] MB | |
| 45 RESULT memoryutil: p= [0.87187, 0.88523, 0.86478, 0.89335] percent | |
| 46 | |
| 47 This data is read by the perfbot and used for displaying perf graphs and | |
| 48 regression monitoring. The perfbot link is | |
