== Where to get this information ==
* Talos tests are defined in [https://dxr.mozilla.org/mozilla-central/source/testing/talos/talos/test.py test.py]
* Treeherder abbreviations are defined in [https://github.com/mozilla/treeherder-service/blob/master/treeherder/etl/buildbot.py#L796 buildbot.py]
* Talos suites are configured for production in [https://hg.mozilla.org/build/buildbot-configs/file/tip/mozilla-tests/config.py config.py]; these names are mapped to Treeherder via regexes: [https://github.com/mozilla/treeherder-service/blob/master/treeherder/etl/buildbot.py#L344 buildbot.py]
 
== Talos Test Types ==
 
There are two different species of Talos tests:
 
* [[#Startup Tests]] : start up the browser and wait for either the load event or the paint event and exit, measuring the time
* [[#Page Load Tests]] : load a manifest of pages
 
=== Startup Tests ===
[https://dxr.mozilla.org/mozilla-central/source/testing/talos/talos/startup_test Startup tests] launch Firefox and measure the time to the onload or paint events. We run this in a series of cycles (default to 20) to generate a full set of data.  Tests that currently are startup tests are:
* [https://wiki.mozilla.org/Buildbot/Talos/Tests#ts_paint ts_paint]
* [https://wiki.mozilla.org/Buildbot/Talos/Tests#tpaint tpaint]
* [https://wiki.mozilla.org/Buildbot/Talos/Tests#tresize tresize]
* [https://wiki.mozilla.org/Buildbot/Talos/Tests#sessionrestore.2Fsessionrestore_no_auto_restore.2Fsessionrestore_many_windows sessionrestore[_no_auto_restore/_many_windows]]
* [https://wiki.mozilla.org/Buildbot/Talos/Tests#CanvasMark tcanvasmark] (this is the one test that is a startup test but unique as we run 5 cycles and report a series of numbers)
 
=== Page Load Tests ===
Many of the talos tests use the page loader to load a manifest of pages.
These are tests that load a specific page and measure the time it takes to load the page, scroll the page, draw the page etc.  In order to run a page load test, you need a manifest of pages to run.  The manifest is simply a list of URLs of pages to load, separated by carriage returns, e.g.:
<pre>
https://www.mozilla.org
https://www.mozilla.com
</pre>
Example: [https://dxr.mozilla.org/mozilla-central/source/testing/talos/talos/tests/svgx/svgx.manifest svgx.manifest]
 
Manifests may also specify that a test computes its own data by prepending a <tt>%</tt> in front of the line:
<pre>
% https://www.mozilla.org
% https://www.mozilla.com
</pre>
Example: [https://dxr.mozilla.org/mozilla-central/source/testing/talos/talos/tests/v8_7/v8.manifest v8.manifest]
 
The file you created should be referenced in your test config inside of [[https://dxr.mozilla.org/mozilla-central/source/testing/talos/talos/test.py#l607 test.py]]. for example, open test.py, and look for the line referring to the test you want to run:
<pre>
tpmanifest = '${talos}/page_load_test/svgx/svgx.manifest'
tpcycles = 1 # run a single cycle
tppagecycles = 25 # load each page 25 times before moving onto the next page
</pre>
 
=== Paint Tests ===
Paint tests are measuring the time to receive both the [https://developer.mozilla.org/en/Gecko-Specific_DOM_Events#MozAfterPaint MozAfterPaint] and OnLoad event instead of just the OnLoad event.  Most tests now look for this unless they are an ASAP test, or an internal benchmark
 
=== ASAP Tests ===
We have a variety of tests which we now run in ASAP mode where we render as fast as possible (disabling vsync and letting the rendering iterate as fast as it can using `requestAnimationFrame`).  In fact we have replaced some original tests with the 'x' versions to make them measure.  We do this with RequestAnimationFrame().
 
ASAP Tests are:
* [https://wiki.mozilla.org/Buildbot/Talos/Tests#tsvg.2C_tsvgx svgx]
* [https://wiki.mozilla.org/Buildbot/Talos/Tests#tscroll.2C_tscrollx tscrollx]
* [https://wiki.mozilla.org/Buildbot/Talos/Tests#tp5o_scroll tp5o_scroll]
* [https://wiki.mozilla.org/Buildbot/Talos/Tests#tps tps]
* [https://wiki.mozilla.org/Buildbot/Talos/Tests#TART.2FCART tart/cart]
 
=== Internal Benchmarks ===
Many tests have internal benchmarks which we report as accurately as possible.  These are the exceptions to the general rule of calculating the suite score as a geometric mean of the subtest values (which are median values of the raw data from the subtests).
 
Tests which are imported benchmarks are:
* [https://wiki.mozilla.org/Buildbot/Talos/Tests#CanvasMark Canvasmark]
* [https://wiki.mozilla.org/Buildbot/Talos/Tests#V8.2C_version_7 V8 Version 7]
* [https://wiki.mozilla.org/Buildbot/Talos/Tests#kraken Kraken]
* [https://wiki.mozilla.org/Buildbot/Talos/Tests#JSS.2FDomaeo_Tests Dromaeo]
 
=== Row Major vs. Column Major ===
 
To get more stable numbers, tests are run multiple times. There are two ways that we do this: row major and column major. Row major means each test is run multiple times and then we move to the next test (and run it multiple times). Column major means that each test is run once one after the other and then the whole sequence of tests is run again.
 
More background information about these approaches can be found in Joel Maher's [https://elvis314.wordpress.com/2012/03/12/reducing-the-noise-in-talos/ Reducing the Noise in Talos] blog post.
 
=== tp5n pages set ===
 
Some tests make use of a set of 50 "real world" pages, known as the tp5n set. These pages are not part of the talos repository, but without them the tests which use them won't run.
* To add these pages to your local setup, download [https://people.mozilla.org/~jmaher/taloszips/zips/tp5n.zip tp5n.zip], and extract it such that `'''tp5n'''` ends up as `testing/talos/talos/tests/'''tp5n'''`.

These tests run the third-party [http://www.kevs3d.co.uk/dev/canvasmark/ CanvasMark] benchmark suite, which measures the browser's ability to render a variety of canvas animations at a smooth framerate as the scenes grow more complex.
 
Results are a score "based on the length of time the browser was able to maintain the test scene at greater than 30 FPS, multiplied by a weighting for the complexity of each test type".

|Measures average frames interval while animating a simple WebGL scene
|}
 
This tests animates a simple WebGL scene (static textured landscape, one moving light source, rotating viewport) and measure the frames throughput (expressed as average interval) over 100 frames. It runs in ASAP mode (vsync off) and measures the same scene 4 times - for all combination of antialiasing and alpha. It reports the results as 4 values - one for each combination. Lower results are better.

|tp5o_scroll
|Measures average frames interval while scrolling the pages of the tp5o set
|}
 
This test is identical to tscrollx, but it scrolls the 50 pages of the tp5o set (rather than 6 synthetic pages which tscrollx scrolls). For each page, the test waits 500ms after the page load event fires, then iterates 100 scroll steps of 10px each (or until the bottom of the page is reached - whichever comes first), then reports the average frame interval.

==== Possible regression causes ====
Some examples of things that cause regressions in this test are:
* Increased displayport size (which causes a larger display list to be built)
* Slowdown in the building of display list
* Slowdown in rasterization of content
 
=== tp5 ===
* contact: :jmaher
* source: [https://people.mozilla.org/~jmaher/taloszips/zips/tp5n.zip tp5n.zip]
* type: [https://wiki.mozilla.org/Buildbot/Talos#Page_Load_Tests PageLoader]
* data: we load each of the 51 tp5o pages 25 times, resulting in 51 sets of 25 data points.
* '''To run it locally''', you'd need [[#tp5n_pages_set|tp5n.zip]].
* summarization:
** subtest: [https://wiki.mozilla.org/Buildbot/Talos/Data#ignore_first ignore first] '''5''' data points, then take the [https://wiki.mozilla.org/Buildbot/Talos/Data#median median] of the remaining 20; [https://dxr.mozilla.org/mozilla-central/source/testing/talos/talos/test.py#l449 source: test.py]
** suite: [https://wiki.mozilla.org/Buildbot/Talos/Data#geometric_mean geometric mean] of the 51 subtest results.

|tp5o
|tp5 with limited pageset (48 pages as others have too much noise)
|}
 
Tests the time it takes Firefox to load the [https://people.mozilla.org/~jmaher/taloszips/zips/tp5n.zip tp5 web page test set]. The web set was culled from the Alexa top 500 April 8th, 2011 and consists of 51 pages.
 
Here are the broad steps we use to create the test set:
# Take the Alexa top 500 sites list
# Remove all sites with questionable or explicit content
# Remove duplicate site (for ex. many Google search front pages)
# Manually select to keep interesting pages (such as pages in different locales)
# Select a more representative page from any site presenting a simple search/login/etc. page
# Deal with Windows 255 char limit for cached pages
# Limit test set to top 100 pages
 
Note that the above steps did not eliminate all outside network access so we had to take further action to scrub all the pages so that there are 0 outside network accesses (this is done so that the tp test is as deterministic measurement of our rendering/layout/paint process as possible).

Measures the delay for the event loop to process a [[Performance/Snappy#Current Infrastructure|tracer event]].  For more details, see {{bug|631571}}.
 
The score on this benchmark is proportional to the sum of squares of all event delays that exceed a 20ms threshold.  Lower is better.
 
We collect 8000+ data points from the browser during the test and apply [https://dxr.mozilla.org/mozilla-central/source/testing/talos/talos/output.py#l95 this formula] to the results:

An svg-only number that measures SVG rendering performance, with animations or iterations of rendering. This is an ASAP test -- i.e. it iterates in unlimited frame-rate mode thus reflecting the maximum rendering throughput of each test. The reported value is the overall duration the sequence/animation took to complete.  To turn on ASAP mode, we set these preferences:
preferences = {'layout.frame_rate': 0, 'docshell.event_starvation_delay_hint': 1}

==== Possible regression causes ====
* Did you change the dimensions of the content area? Even a little? The tsvgx test seems to be sensitive to changes like this. See {{bug|1375479}}, for example. Usually, these sorts of "regressions" aren't real regressions - they just mean that we need to re-baseline our expectations from the test.

Renders many semi-transparent, partially overlapping SVG rectangles, and measures time to completion of this rendering.
 
Note that this test also tends to reflect changes in network efficiency and navigation bar rendering issues:
 
* Most of the page load tests measure from before the location is changed, until onload + mozafterpaint, therefore any changes in chrome performance from the location change, or network performance (the pages load from a local web server) would affect page load times. SVG opacity is rather quick by itself, so any such chrome/network/etc performance changes would affect this test more than other page load tests (relatively, in percentages).

Tests the amount of time it takes the open a new window. This test does not include startup time. Multiple test windows are opened in succession, results reported are the average amount of time required to create and display a window in the running instance of the browser. (Measures ctrl-n performance.)

=== Dromaeo Tests ===
 
Dromaeo suite of tests for JavaScript performance testing. See the [https://wiki.mozilla.org/Dromaeo Dromaeo wiki] for more information.
 
This suite is divided into several sub-suites.
 
Each sub-suite is divided into tests, and each test is divided into sub-tests.  Each sub-test takes some (in theory) fixed piece of work and measures how many times that piece of work can be performed in one second.  The score for a test is then the geometric mean of the runs/second numbers for its sub-tests.  The score for a sub-suite is the geometric mean of the scores for its tests.
 
==== Dromaeo CSS ====
* contact: :bz, :jmaher
* source: [[https://dxr.mozilla.org/mozilla-central/source/testing/talos/talos/tests/dromaeo css.manifest]]
* type: PageLoader
* reporting: speed in test runs per second (higher is better)
* data: Dromaeo has 6 subtests which run internal benchmarks, each benchmark reports about 180 raw data points each
summarization:
* subtest: Dromaeo is a custom benchmark which has a lot of micro tests inside each subtest, because of this we use a custom [https://wiki.mozilla.org/Buildbot/Talos/Data#dromaeo dromaeo filter] to summarize the subtest.  Each micro test produces 5 data points and for each 5 data points we take the mean, leaving 36 data points to represent the subtest (assuming 180 points).  These 36 micro test means, are then run through a geometric_mean to produce a single number for the dromaeo subtest. [https://dxr.mozilla.org/mozilla-central/source/testing/talos/talos/test.py#l527 source: filter.py]
** suite: [https://wiki.mozilla.org/Buildbot/Talos/Data#geometric_mean geometric mean] of the 6 subtest results.
 
Each page in the manifest is part of the dromaeo css benchmark.  Each page measures the performance of searching the DOM for nodes matching various CSS selectors, using different libraries for the selector implementation (jQuery, Dojo, Mootools, ExtJS, Prototype, and Yahoo UI).

Each page in the manifest is part of the dromaeo dom benchmark.  These are the specific areas that Dromaeo DOM covers:
 
===== DOM Attributes =====
Measures performance of getting and setting a DOM attribute, both via <code>getAttribute</code> and via a reflecting DOM property.  Also throws in some expando getting/setting for good measure.
 
====== Possible regression causes ======
* None listed yet. If you fix a regression for this test and have some tips to share, this is a good place for them.
 
===== DOM Modification =====
Measures performance of various things that modify the DOM tree: creating element and text nodes and inserting them into the DOM.
 
====== Possible regression causes ======
* None listed yet. If you fix a regression for this test and have some tips to share, this is a good place for them.
 
===== DOM Query =====
Measures performance of various methods of looking for nodes in the DOM: <code>getElementById</code>, <code>getElementsByTagName</code>, and so forth.
 
====== Possible regression causes ======
* None listed yet. If you fix a regression for this test and have some tips to share, this is a good place for them.
 
===== DOM Traversal =====
Measures performance of various accessors (<code>childNodes</code>, <code>firstChild</code>, etc) that would be used when doing a walk over the DOM tree.

|}
 
 
This test scrolls several pages where each represent a different known "hard" case to scroll (* needinfo), and measures the average frames interval (1/FPS) on each. The ASAP test (tscrollx) iterates in unlimited frame-rate mode thus reflecting the maximum scroll throughput per page.  To turn on ASAP mode, we set these preferences:
preferences = {'layout.frame_rate': 0, 'docshell.event_starvation_delay_hint': 1}

A purer form of paint measurement than tpaint. This test opens a single window positioned at 10,10 and sized to 300,300, then resizes the window outward |max| times measuring the amount of time it takes to repaint each resize. Dumps the resulting dataset and average to stdout or logfile.
 
In {{bug|1102479}} tresize was rewritten to work in e10s mode which involved a full rewrite of the test.
 
To run resize locally without talos, please [https://hg.mozilla.org/mozilla-central/raw-file/tip/testing/talos/talos/generate-tresize-xpi.html install the addon] to run the test locally.

=== TART/CART ===
* contact: :avih, :jmaher, :MattN
* source: [https://dxr.mozilla.org/mozilla-central/source/testing/talos/talos/tests/tart tart]
* type: PageLoader
* measuring: Desktop Firefox UI animation speed and smoothness
* reporting: intervals in ms (lower is better) - see below for details
* data: there are 30 reported subtests from TART which we load 25 times, resulting in 30 sets of 25 data points.
* summarization:
** subtest: [https://wiki.mozilla.org/Buildbot/Talos/Data#ignore_first ignore first] data point, then take the [https://wiki.mozilla.org/Buildbot/Talos/Data#median median] of the remaining 24 data points; [https://dxr.mozilla.org/mozilla-central/source/testing/talos/talos/test.py#l305 source: test.py]
** suite: [https://wiki.mozilla.org/Buildbot/Talos/Data#geometric_mean geometric mean] of the 30 subtest results.
 
TART is the '''Tab Animation Regression Test''' and CART is the '''Customize Animation Regression Test'''.
 
TART tests tab animation on these cases:
* Simple: single new tab of about:blank open/close without affecting (shrinking/expanding) other tabs.
* icon: same as above with favicons and long title instead of about:blank.
* Newtab: newtab open with thumbnails preview - without affecting other tabs, with and without preload.
* Fade: opens a tab, then measures fadeout/fadein (tab animation without the overhead of opening/closing a tab).
** Case 1 is tested with DPI scaling of 1.
** Case 2 is tested with DPI scaling of 1.0 and 2.0.
** Case 3 is tested with the default scaling of the test system.
** Case 4 is tested with DPI scaling of 2.0 with the "icon" tab (favicon and long title).
** Each animation produces 3 test results:
*** error: difference between the designated duration and the actual completion duration from the trigger.
*** half: average frame interval over the 2nd half of the animation.
*** all: average frame interval over all recorded intervals.
*** And the run logs also include the explicit intervals from which these 3 values were derived.
 
CART uses the same framework to measure performance of the Australize "customize" animation (for entering the toolbar/menu customization view). Subtests include:
* Customize-enter animation (full and css-animation-only part).
* Customize-exit animation
 
TART/CART can be used as a stand-alone addon:
* Set the browser to ASAP mode (preferences layout.frame_rate=0, docshell.event_starvation_delay_hint=1). This makes the browser refresh the screen as fast as possible instead of limiting it to 60hz, thus allows higher resolution measurements. Requires restart to take effect.
* [https://hg.mozilla.org/mozilla-central/raw-file/tip/testing/talos/talos/generate-tart-xpi.html Install the latest addon xpi], or zip the addon dir of the source code, rename the extension to xpi and install.
* Visit chrome://tart/content/tart.html
* Select subtests to run. By default the selected tests are all the TART tests. CART is the "Customize" test.

==== Possible regression causes ====
* CART
** Regressions might be reported for patches that add new buttons to the menu panel by default, since this can add new rows to the panel and make it scrollable, which increases the amount of work to do during the transition. See {{bug|1230671}} for details.
 
=== DAMP ===
 
* contact: :bgrins, :jmaher
* source: [https://dxr.mozilla.org/mozilla-central/source/testing/talos/talos/tests/devtools damp]
* type: PageLoader
* measuring: Developer Tools toolbox startup, shutdown, and reload performance
* reporting: intervals in ms (lower is better) - see below for details
* data: there are 36 reported subtests from DAMP which we load 25 times, resulting in 36 sets of 25 data points.
* summarization:
** subtest: [https://wiki.mozilla.org/Buildbot/Talos/Data#ignore_first ignore first] data point, then take the [https://wiki.mozilla.org/Buildbot/Talos/Data#median median] of the remaining 24 data points; [https://dxr.mozilla.org/mozilla-central/source/testing/talos/talos/test.py#l356 source: test.py]
** suite: [https://wiki.mozilla.org/Buildbot/Talos/Data#geometric_mean geometric mean] of the 36 subtest results.
 
To run this locally, you'll need to pull down the tp5 page set and run it in a local web server.  See the [https://wiki.mozilla.org/Buildbot/Talos/Tests#tp5 tp5 section] or contact jmaher for more information.

Three tests measure the time spent reading and restoring the session from a valid sessionstore.js. Time starts ticking during event sessionRestoreInit and stops during event sessionRestored.
 
In ''sessionrestore'', this is tested with a configuration that requires the session to be restored. In ''sessionrestore_no_auto_restore'', this is tested with a configuration that requires the session to not be restored. Both of the above tests use a sessionstore.js file that contains one window and roughly 89 tabs. In ''sessionrestore_many_windows'', this is tested with a sessionstore.js that contains 3 windows and 130 tabs. The first window contains 50 tabs, 80 remaning tabs are divided equally between the second and the third window.

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:
 
{| cellspacing="1" cellpadding="1" border="1"
|-
| Talos test name
| Description
|-
| tp6_amazon
| Measures page load of an amazon search result for the keyword "laptop"
|-
| tp6_facebook
| Measures page load of a facebook timeline (post-login)
|-
| tp6_google
| Measures page load of a google search result for the keywords "barack obama"
|-
| tp6_youtube
| Measures page load of the youtube home page
|}

==== Possible regression causes ====
Some examples of things that cause regressions in this test are:
* Please update this when regressions are found
 
=== Stylo gtest microbenchmarks ===
 
* contact: :bholley, :SimonSapin
* source: [https://dxr.mozilla.org/mozilla-central/source/layout/style/test/gtest]
* type: [https://wiki.mozilla.org/Buildbot/Talos/Tests#Microbench Microbench]
* reporting: intervals in ms (lower is better)
* data: each test is run and measured 5 times
* summarization: take the [https://wiki.mozilla.org/Buildbot/Talos/Data#median median] of the 5 data points; [https://dxr.mozilla.org/mozilla-central/source/testing/gtest/mozilla/MozGTestBench.cpp#43-46 source: MozGTestBench.cpp]
 
 
Servo_StyleSheet_FromUTF8Bytes_Bench parses a sample stylesheet 20 times with Stylo’s CSS parser that is written in Rust. It starts from an in-memory UTF-8 string, so that I/O or UTF-16-to-UTF-8 conversion is not measured.
 
Gecko_nsCSSParser_ParseSheet_Bench does the same with Gecko’s previous CSS parser that is written in C++, for comparison.
 
Servo_DeclarationBlock_SetPropertyById_Bench parses the string "10px" with Stylo’s CSS parser and sets it as the value of a property in a declaration block, a million times. This is similar to animations that are based on JavaScript code modifying Element.style instead of using CSS @keyframes.
 
Servo_DeclarationBlock_SetPropertyById_WithInitialSpace_Bench is the same, but with the string " 10px" with an initial space. That initial space is less typical of JS animations, but is almost always there in stylesheets or full declarations like "width: 10px". This microbenchmark was used to test the effect of some specific code changes. Regressions here may be acceptable if Servo_StyleSheet_FromUTF8Bytes_Bench is not affected.
