1 Layout test analyzer script.
5 This script requires PySVN (http://pysvn.tigris.org/) to be installed on the
10 python layouttest_analyzer.py (Please run with '-h' for available command-line
13 Example: python layouttest_analyzer.py -r imasaki@chromium.org
14 -t /var/www/analyzer/graph.html
16 * File/Directory structure
22 test_data/: data for unit tests.
23 graph/: the default location for graph files.
24 anno/: the default location for bug annotation files.
25 result/: the default location for the analyzer results.
26 testname/: the default location for the test group definition files in CSV.
30 1) using PySVN, the script collects layout test of interest
31 (specified in command-line parameter and testnames/*.csv file) from
32 Webkit SVN repository as well as test description. Then, it gets the
33 latest test expectation file and does the simple parsing. The
34 parsed test expectation is joined with the layout tests using test name
35 as its join key. The tests are classified into 'whole', 'skip',
36 'nonskip' test groups. 'Whole' contains all tests, 'skip' contains
37 tests that are skipped as specified in the test expectation file, 'nonskip'
38 tests are in the test expectation file and not skipped (these are tests
41 2) the script reads the previous latest analyzer results, then,
42 compares it with current results for each test group ('whole', 'skip',
43 and 'nonskip'). It also looks into the SVN test expectation history
44 diff for the time period for the test names of interest.
46 3) all obtained information is sent out to a email list specified
47 in the parameters in pretty HTML format.
49 4) the trend graph is updated using the current results.
55 A class to store test names in layout tests. The test names (including
56 regular expression patterns) are read from a CSV file and used for
57 getting layout test names from Webkit SVN as well as test description.
61 A class to model the content of test expectation file for analysis.
62 The location of the test expectations file can be found in
63 |TEST_EXPECTATIONS_LOCATIONS|. It is necessary to parse this
64 file and store meaningful information for the analysis (joining with
65 existing layout tests using a test name). Instance variable
66 |all_test_expectation_info| is used. A test name such as
67 'media/video-source-type.html' is used for the key to store
68 information. However, a test name can appear multiple times in the
69 test expectation file. So, the map should keep all the occurrence
70 information. For example, the current test expectation file has the
71 following two entries:
73 BUGWK58587 LINUX DEBUG GPU : media/video-zoom.html = IMAGE
74 BUGCR86714 MAC GPU : media/video-zoom.html = CRASH IMAGE
76 In this case, all_test_expectation_info['media/video-zoom.html'] will
77 have a list with two elements, each of which is the map of the test
78 expectation information.
80 ** TestExpectationsHistory:
82 A class to represent history of the test expectation file. The history
83 is obtained by calling PySVN.log()/diff() APIs using the specified time
88 A class to manage trend graph which is using Google Visualization
89 APIs. Google Visualization API
90 (http://code.google.com/apis/chart/interactive/docs/gallery/annotatedtimeline.html)
91 is used to present the historical analyzer result. Currently, data
92 is directly written to JavaScript file using file in-place
93 replacement for simplicity.
