The bloom_basic test (perf-reftest suite) is a unique talos suite that loads two different test pages: a 'base' page (bloom_basic) and a 'reference' page (bloom_basic_ref), and then compares each of the page load times against eachother to determine the variance. | |||
Talos runs each of the two pages as if they are stand-alone tests, and then calculates and reports the variance; the test output 'replicates' reported from bloom_basic are actually the comparisons between the 'base' and 'reference' pages for each page load cycle. | |||
If you wish to see the individual 'base' and 'reference' page results instead of just the reported difference, the 'base_replicates' and 'ref_replicates' can be found in the PERFHERDER_DATA log file output, and in the 'local.json' talos output file when running talos locally. In production, both of the page replicates are also archived in the perfherder-data.json file. The perfherder-data.json file is archived after each run in production, and can be found on the Treeherder Job Details tab when the perf-reftest job symbol is selected. | |||
Bloom_basic ensures that we correctly fast-reject ancestor selectors that clearly don't | |||
match any ancestor elements. If the bloom filter isn't working correctly, | |||
the 'test' page will take orders of magnitude longer. The 'ref' page will | |||
take somewhat longer, but not nearly as much. | |||

** suite: identical to subtest; each tp6_* test is reported individually (they're NOT aggregated) | |||
* NOTE: Currently only supported on Windows | |||
The talos tp6 (also known as 'quantum-pageload') test suite loads various pages and reports their load times. Each test page/URL is reported individually. The result values (ms) is the 'time to first non-blank paint'. | |||
Instead of loading the page sets from a local file, a tool called [http://docs.mitmproxy.org/en/latest/introduction.html mitmproxy] is used to playback page archives via an https proxy. When the tp6 suite is run via ./mach talos-test, mozharness automatically downloads and installs the mitmproxy tool and pageset archives. | |||
The mitmproxy tool is started, the proxy setup in Firefox, and the mitmproxy https security certificate is loaded into Firefox, all automatically. The pagesets are made available for playback via the proxy, at which point each of the tp6 test pages are ready for load and measurement. | |||
The tp6 suite currently consists of these individual pageload tests: | |||
