Pageload Test Component ======================= Usage: ./firefox -tp file:///path/to/manifest.txt [-tpargs...] See ./firefox -help for other arguments. Manifest file format ==================== Comments in the manifest file start with a #. Each line may be: * a URL (absolute or relative to the manifest) This URL is added to the list of tests. * one or more flags, followed by whitespace, followed by a URL The only flag supported currently is '%', which indicates that a test will do its own timing. (See Self-timing Tests below.) * "include" followed by whitespace, followed by a URL Parse the given manifest file. Self-timing Tests ================= Most timing tests are interested in timing how long it takes the page to load; that is, from the start of page loading until the 'load' event is dispatched. By default, this is what the pageloader will time. However, if a test URL has the % flag, the test is expected to report its own timing. For this purpose, the pageloader will provide a function named "tpRecordTime" in the test's global object that it should call once it has performed whatever timing it wants to do. The given value will be used as the timing result for this test. Output format ============= The result is a dump to stdout via dump() -- browser.dom.window.dump.enabled must be set to true in the profile. A number of output formats can be specified via the -tpformat command line option, currently 'js', 'text', and 'tinderbox' are supported. Sample 'js' format output: ([({page:"1280x1024-PNG/index.html", value:133, stddev:20.049937655763422}),({page:"bugzilla.mozilla.org/index.html", value:233, stddev:36.66606060105176}),({page:"espn.go.com/index.html", value:117.6, stddev:1.2}),({page:"home.netscape.com/index.html", value:97.8, stddev:47.41898354035017}),]) Sample 'text' format output: ============================================================ Page mean stdd min max raw 0 1280x1024-PNG/index.html 133 20 121 297 297,173,122,121,124,125 1 bugzilla.mozilla.org/index.html 233 37 192 395 395,273,223,192,198,279 2 espn.go.com/index.html 118 1 116 254 254,117,116,119,119,117 3 home.netscape.com/index.html 98 47 3 124 3,121,120,124,124,121 ============================================================ Sample 'tinderbox' format output: __start_tp_report _x_x_mozilla_page_load,778.5,NaN,NaN _x_x_mozilla_page_load_details,avgmedian|778.5|average|766.75|minimum|NaN|maximum|NaN|stddev|NaN|0;file:///c:/proj/mozilla-cvs/perf/tp2/base/www.cnn.com/index.html;778.5;766.75;722;1027;1027;788;777;722;780|... __end_tp_report Note that the minimum, maximum, stddev are not calculated; they're always reported as NaN. (They were the minimum and maximum values of any sampled value, and the standard deviation across all sampled values -- not very useful.) TODO ==== * Command line option to choose whether to run with or without browser chrome. Currently runs without. * Tinderbox-dropping style output * better yet would be to teach tinderbox about JSON
