# Organisational

## openQA calls

Currently there are two recurring openQA calls conducted at SUSE on http://jangouts.suse.de/. If there would be more interest from the outside the call could be made on a public platform.

Both meetings should target to finish in 15 minutes each. If more time is needed, propose to stay in the call with the required subset of attendees.

Standard rules of good "standup meetings" apply here, too, e.g.

* Be on time (be there at meeting start)

* Be concise (help keep the time limit)

* Be polite

* focus on

 * what you achieved

 * what you plan

 * where did you face problems where you could use help

### "openQA backend coordination" call

**objectives**:

* Coordination on openQA backend development

**execution**: A regular daily call from Mon-Fri at 1000 CET/CEST

### "SUSE QA test coordination" call

**objectives**:

* Coordination on openQA based test development, especially SLE products

* Information about important development in openQA backend by backend responsibles

**execution**: Mon + Wed, at 1030 CET/CEST

If somebody from SUSE QA team will do back-end development he can attend the first call as well, of course.

* **wip**: Marked by the reviewee itself as "[WIP]" or "[DO-NOT-MERGE]" or similar

* **question**: Questions to the reviewee, not answered yet

# Use cases

The following use cases 1-6 have been defined within a SUSE workshop (others have been defined later) to clarify how different actors work with openQA. Some of them are covered already within openQA quite well, some others are stated as motivation for further feature development.

# Glossary

The following terms are used within the context of openQA:

 * ***test modules***: an individual test case in a single perl module file, e.g. "sshxterm". If not further specified a test module is denoted with its "short name" equivalent to the filename including the test definition. The "full name" is composed of the *test group* (TBC), which itself is formed by the top-folder of the test module file, and the short name, e.g. "x11-sshxterm" (for x11/sshxterm.pm)

 * ***test suite***: a collection of *test modules*, e.g. "textmode". All *test modules* within one *test suite* are run serially

 * ***job***: one run of individual test cases in a row denoted by a unique number for one instance of openQA, e.g. one installation with subsequent testing of applications within gnome

 * ***test run***: equivalent to *job*

 * ***test result***: the result of one job, e.g. "passed" with the details of each individual *test module*

 * ***test step***: the execution of one *test module* within a *job*

 * ***distri***: a test distribution but also sometimes referring to a *product* (CAUTION: ambiguous, historically a "GNU/Linux distribution"), composed of multiple ***test modules*** in a folder structure that compose ***test suites***, e.g. "opensuse" (test distribution, short for "os-autoinst-distri-opensuse")

 * ***product***: the main "system under test" (SUT), e.g. "openSUSE"

 * ***job group***: equivalent to *product*, used in context of the webUI

 * ***version***: one version of a *product*, don't confuse with *builds*, e.g. "Tumbleweed"

 * ***flavor***: a specific variant of a *product* to distinguish differing variants, e.g. "DVD"

 * ***arch***: an architecture variant of a *product*, e.g. "x86_64"

 * ***machine***: additional variant of machine, e.g. used for "64bit", "uefi", etc.

 * ***scenario***: A composition of `<distri>-<version>-<flavor>-<arch>-<test_suite>@<machine>`, e.g. "openSUSE-Tumbleweed-DVD-x86_64-gnome@64bit", nicknamed *koala*

 * ***build***: Different versions of a product as tested, can be considered a "sub-version" of *version*, e.g. "Build1234"; CAUTION: ambiguity: either with the prefix "Build" included or not)

# Thoughts about categorizing test results, issues, states within openQA

by okurz

When reviewing test results it is important to distinguish between different causes of "failed tests"

## Nomenclature

### Test status categories

A common definition about the status of a test regarding the product it tests: "false|true positive|negative" as described on https://en.wikipedia.org/wiki/False_positives_and_false_negatives. "positive|negative" describes the outcome of a test ("positive": PASSED; "negative": FAILED) whereas "false|true" describes the conclusion of the test regarding the presence of issues in the SUT or product in our case ("true": correct reporting; "false": incorrect reporting), e.g. "true negative", test successful, no issues detected and there are no issues, product is working as expected by customer. Another example: Think of testing as of a fire alarm. An alarm (event detector) should only go off (be "positive") *if* there is a fire (event to detect) --> "true positive" whereas *if* there is *no* fire there should be *no* alarm --> "true negative".

Another common but potentially ambiguous categorization:

* *broken*: the test is not behaving as expected (Ambiguity: "as expected" by whom?) --> commonly a "false positive", can also be "false negative" but hard to detect

* *failing*: the test is behaving as expected, but the test output is a fail --> "true positive"

* *working*: the test is behaving as expected (with no comment regarding the result, though some might ambiguously imply 'result is negative')

* *passing*: the test is behaving as expected, but the result is a success --> "true negative"

If in doubt declare a test as "broken". We should review the test and examine if it is behaving as expected.

Be careful about "positive/negative" as some might also use "positive" to incorrectly denote a passing test (and "negative" for failing test) as an indicator of "working product" not an indicator about "issue present". If you argue what is "used in common speech" think about how "false positive" is used as in "false alarm" --> "positive" == "alarm raised", also see https://narainko.wordpress.com/2012/08/26/understanding-false-positive-and-false-negative/

### Priorization of work regarding categories

In this sense development+QA want to accomplish a "true negative" state whenever possible (no issues present, therefore none detected). As QA and test developers we want to prevent "false positives" ("false alarms" declaring a product as broken when it is not but the test failed for other reasons), also known as "type I error" and "false negatives" (a product issue is not catched by tests and might "slip through" QA and at worst is only found by an external outside customer) also known as "type II error". Also see https://en.wikipedia.org/wiki/Type_I_and_type_II_errors. In the context of openQA and system testing paired with screen matching a "false positive" is much more likely as the tests are very susceptible to subtle variations and changes even if they should be accepted. So when in doubt, create an issue in progress, look at it again, and find that it was a false alarm, rather than wasting more peoples time with INVALID bug reports by believing the product to be broken when it isn't. To quote Richard Brown: "I […] believe this is the route to ongoing improvement - if we have tests which produce such false alarms, then that is a clear indicator that the test needs to be reworked to be less ambiguous, and that IS our job as openQA developers to deal with".

## Further categorization of statuses, issues and such in testing, especially automatic tests

By okurz

This categorization scheme is meant to help in communication in either written or spoken discussions being simple, concise, easy to remember while unambiguous in every case.

While used for naming it should also be used as a decision tree and can be followed from the top following each branch.

### Categorization scheme

To keep it simple I will try to go in steps of deciding if a potential issue is of one of two categories in every step (maybe three) and go further down from there. The degree of further detailing is not limited, i.e. it can be further extended. Naming scheme should follow arabic number (for two levels just 1 and 2) counting schemes added from the right for every additional level of decision step and detail without any separation between the digits, e.g. "1111" for the first type in every level of detail up to level four. Also, I am thinking of giving the fully written form phonetic name to unambiguously identify each on every level as long as not more individual levels are necessary. The alphabet should be reserved for higher levels and higher priority types.

Every leaf of the tree must have an action assigned to it.

1 **failed** (ZULU)

11 new (passed->failed) (YANKEE)

111 product issue ("true positive") (WHISKEY)

1111 unfiled issue (SIERRA)

11111 hard issue (KILO)

111121 critical / potential ship stopper (INDIA) --> immediately file bug report with "ship_stopper?" flag; opt. inform RM directly

111122 non-critical hard issue (HOTEL) --> file bug report

11112 soft issue (JULIETT) --> file bug report

1112 bugzilla bug exists (ROMEO)

11121 bug was known to openqa / openqa developer --> cross-reference (bug->test, test->bug) AND raise review process issue, improve openqa process

11122 bug was filed by other sources (e.g. beta-tester) --> cross-reference (bug->test, test->bug)

112 test issue ("false positive") (VICTOR)

1121 progress issue exists (QUEBEC) --> cross-reference (issue->test, test->issue)

1122 unfiled test issue (PAPA)

11221 easy to do w/o progress issue

112211 need needles update --> re-needle if sure, TODO how to notify?

112212 pot. flaky, timeout

1122121 retrigger yields PASS --> comment in progress about flaky issue fixed

1122122 reproducible on retrigger --> file progress issue

11222 needs progress issue filed --> file progress issue

12 existing / still failing (failed->failed) (XRAY)

121 product issue (UNIFORM)

1211 unfiled issue (OSCAR) --> file bug report AND raise review process issue (why has it not been found and filed?)

1212 bugzilla bug exists (NOVEMBER) --> ensure cross-reference, also see rules for 1112 ROMEO

122 test issue (TANGO)

1221 progress issue exists (MIKE) --> monitor, if persisting reprioritize test development work

1222 needs progress issue filed (LIMA) --> file progress issue AND raise review process issue, see 1211 OSCAR

2 **passed** (ALFA)

21 stable (passed->passed) (BRAVO)

211 existing "true negative" (DELTA) --> monitor, maybe can be made stricter

212 existing "false negative" (ECHO) --> needs test improvement

22 fixed (failed->passed) (CHARLIE)

222 fixed "true negative" (FOXTROTT) --> TODO split monitor, see 211 DELTA

2221 was test issue --> close progress issue

2222 was product issue

22221 no bug report exists --> raise review process issue (why was it not filed?)

22222 bug report exists

222221 was marked as RESOLVED FIXED

221 fixed but "false negative" (GOLF) --> potentially revert test fix, also see 212 ECHO

Priority from high to low: INDIA->OSCAR->HOTEL->JULIETT->…

### Further decision steps working on test issues

Test issues could be one of the following sources

* "accepted product changes"

 * product changed slightly but in an acceptable way without the need for communication with DEV+RM --> adapt test

 * product changed slightly but in an acceptable way found after feedback from RM --> adapt test

 * product changed significantly --> after approval by RM adapt test

* changes in test setup, e.g. our test hardware equipment behaves different or the network

* changes in test infrastructure software, e.g. os-autoinst, openQA

* changes in test management configuration, e.g. openQA database settings

* changes in the test software itself (the test plan in source code as well as needles)

* if none of the above it could be a hidden sporadic issue, i.e. the root problem is already hidden in the system for a long time but does not show symptoms every time

# Advanced features in openQA

There are some features in openQA for reviewing test results and common practices. Some of these features are presented here based on the pull requests from github.

## Show previous results in test results page [gh#538](https://github.com/os-autoinst/openQA/pull/538)

On a tests result page there is a tab for "previous results" showing the result of test runs in the same scenario. This shows previous builds as well as test runs in the same build. This way you can easily check and compare results from before including any comments, labels, bug references (see next section). This helps to answer questions like "Is this a new issue", "Is it reproducable", "has it been seen in before", "how does the history look like".

Querying the database for former test runs of the same scenario is a rather

costly operation which we do not want to do for multiple test results at once

but only for each individual test result (1:1 relation). This is why this is done in each individual test result and not for a complete build.

The evaluation of previous jobs is limited but can be adjusted with the query parameter `limit_previous=<nr>` in the test URL, e.g. to provide a link to the tab in the results page showing the previous 30 results of test 1234 on openqa.opensuse.org you would write

`http://openqa.opensuse.org/tests/1234?limit_previous=30#previous`

Remember that the higher the limit, the more complex the database queries will be increasing the lookup time as well as the load on openQA to generate the result.

Related issue: #10212

Screenshot of feature:

![screenshot_20160210_142024](https://cloud.githubusercontent.com/assets/1693432/12948308/7e915a3c-d001-11e5-840b-2f070c3cb8a5.png)

## Link to latest in scenario name [gh#836](https://github.com/os-autoinst/openQA/pull/836)

Find the always latest job in a scenario with the link after the scenario name in the tab "Previous results"

Screenshot:

![openqa_link_to_latest_in_previous](https://cloud.githubusercontent.com/assets/1693432/18145393/5b5fb544-6fcb-11e6-967b-f24ffc6a498c.png)

## Add 'latest' query route [gh#815](https://github.com/os-autoinst/openQA/pull/815)

Should always refer to most recent job for the specified scenario.

* have the same link for test development, i.e. if one retriggers tests, the

person has to always update the URL. If there would be a static URL even the

browser can be instructed to reload the page automatically

* for linking to the always current execution of the last job within one

scenario, e.g. to respond faster to the standard question in bug reports "does

this bug still happen?"

Examples:

* `tests/latest?distri=opensuse&version=13.1&flavor=DVD&arch=x86_64&test=kde&machine=64bit`

* `tests/latest?flavor=DVD&arch=x86_64&test=kde`

* `tests/latest?test=foobar` - this searches for the most recent job using test_suite 'foobar' covering all distri, version, flavor, arch, machines. To be more specific, add the other query entries.

## Add web UI controls to select 20/50/100/400 previous results [gh#744](https://github.com/os-autoinst/openQA/pull/744)

The query parameter 'limit_previous' allows to show more than the default 10

previous results on demand for some time. There are web UI

selections below the table of the previous build to reload the same page with

higher number of previous results on demand.

Example screenshot:

![openqa_limit_previous_results_gui_100percent_padded](https://cloud.githubusercontent.com/assets/1693432/16642470/7f3cf080-440b-11e6-84b2-0485b2fd1810.png)

## Show bug or label icon on overview if labeled [gh#550](https://github.com/os-autoinst/openQA/pull/550)

* Show bug icon with URL if mentioned in test comments

* Show bug or label icon on overview if labeled

For bugreferences write `<bugtracker_shortname>#<bug_nr>` in a comment, e.g. "bsc#1234", for generic labels use `label:<keyword>` where `<keyword>` can be any valid character up to the next whitespace, e.g. "false_positive". The keywords are not defined within openQA itself. A valid list of keywords should be decided upon within each project or environment of one openQA instance.

Example for a generic label:

![openqa_generic_label](https://cloud.githubusercontent.com/assets/1693432/13027322/7bce7992-d24a-11e5-99ee-839fb5e82169.png)

Example for bug label:

![openqa_bug_label](https://cloud.githubusercontent.com/assets/1693432/13027323/8555238a-d24a-11e5-83d5-5bb2d2140860.png)

Related issue: #10212

## Show certificate next to builds on overview if all failures are labeled [gh#560](https://github.com/os-autoinst/openQA/pull/560)

Based on comments in the individual job results for each build a certificate

icon is shown on the group overview page as well as the index page to indicate

that every failure has been reviewed, e.g. a bug reference or a test issue

reason is stated. Only the failed and incomplete jobs are regarded for the

evaluation if a build is considered "reviewed".

If the badge appears you know you are done for one complete build :-)

Example screenshot:

![openqa_reviewed_label](https://cloud.githubusercontent.com/assets/1693432/13145996/eb1bb78a-d653-11e5-9f0f-40898915578e.png)

## Allow group overview query by result [gh#531](https://github.com/os-autoinst/openQA/pull/531)

This allows e.g. to show only failed builds. Could be included like in http://lists.opensuse.org/opensuse-factory/2016-02/msg00018.html for "known defects".

Example: Add query parameters like `…&result=failed&arch=x86_64` to show only failed for the single architecture selected.

## Add web UI controls to select more builds in group_overview [gh#804](https://github.com/os-autoinst/openQA/pull/804)

The query parameter 'limit_builds' allows to show more than the default 10

builds on demand. Just like we have for configuring previous results, the

current commit adds web UI selections to reload the same page with

higher number of builds on demand. For this, the limit of days is increased

to show more builds but still limited by the selected number.

Example screenshot:

![openqa_limit_builds_current_bold](https://cloud.githubusercontent.com/assets/1693432/17462279/59e344e6-5ca8-11e6-8350-42a0fbb5267d.png)

## Add more query parameters for configuring last builds [gh#575](https://github.com/os-autoinst/openQA/pull/575)

By using advanced query parameters in the URLs you can configure the search for builds.

Higher numbers would yield more complex database queries but can be selected

for special investigation use cases with the advanced query parameters, e.g. if one wants to get an overview of a longer history.

This applies to both the index dashboard and group overview page.

Example to show up to three week old builds instead of the default two weeks

with up to 20 builds instead of up to 10 being the default for the group

overview page:

    http://openqa/group_overview/1?time_limit_days=21&limit_builds=20

## Build tagging and keeping important builds [gh#591](https://github.com/os-autoinst/openQA/pull/591)

### Tag builds with special comments on group overview

Based on comments on the group overview individual builds can be tagged. As

'build' by themselves do not own any data the job group is used to store this

information. A tag has a 'build' to link it to a build. It also has a 'type'

and an optional 'description'. The type can later on be used to distinguish

tag types.

The more recent tag always wins.

A 'tag' icon is shown next to tagged builds together with the description on

the group_overview page. The index page is not changed to prevent a potential

performance regression.

Within the sub group_overview the comments are parsed for comments and then

passed to the template explicitly to prevent duplicate database queries.

### Keeping important builds

As builds can now be tagged we come up with the convention that the

'important' type - the only one for now - is used to tag every job that

corresponds to a build as 'important' and keep the logs for these jobs so that

we can always refer to the attached data, e.g. for milestone builds, final

releases, jobs for which long-lasting bug reports exist, etc.

As these jobs are not cleaned up automatically a manual or external cleanup

scheme has to be applied for important builds and jobs.

### Example screenshot of a tag coment and corresponding tagged build

![openqa_tag_important](https://cloud.githubusercontent.com/assets/1693432/13468316/4fd8f586-e0a2-11e5-99df-4aa3fb787205.png)

Related issue: #9544

## Add web UI controls to filter only tagged or all builds [gh#807](https://github.com/os-autoinst/openQA/pull/807)

Using a new query parameter 'only_tagged=[0|1]' the list can be filtered, e.g. show only tagged (important) builds.

Example screenshot:

![openqa_limit_builds_current_bold_and_only_tagged](https://cloud.githubusercontent.com/assets/1693432/17464792/49bb6b18-5ce7-11e6-8053-7b74faf193a7.png)

Related issue: #11052

## Carry over labels from previous jobs in same scenario if still failing [gh#564](https://github.com/os-autoinst/openQA/pull/564)

It is possible to label all failing tests but tedious to do by a human user

as many failures are just having the same issue until it gets fixed.

It helps if a label is preserved for a build that is still failing. This

idea is inspired by

https://wiki.jenkins-ci.org/display/JENKINS/Claim+plugin

Does not carry over labels over passes: After a job passed a new issue in a subsequent fail is assumed to be failed

for a different reason.

Related issue: #10212

## Distinguish product and test issues bugref [gh#708](https://github.com/os-autoinst/openQA/pull/708)

"progress" is used to track test issues, bugzilla for product issues, at least for SUSE/openSUSE. openQA bugrefs distinguish this and show corresponding icons

![different_bug_icons](https://cloud.githubusercontent.com/assets/1693432/15814910/e4e74bf6-2bc9-11e6-83de-20f18a7494de.png)

## Pinning comments as group description

This is possible by adding the keyword `pinned-description` anywhere in a comment on the group overview page. Then the comment will be shown at the top of the group overview page. However, it only works as operator or admin.

## Filtering test results in test result overview

At the very bottom of the test results overview page is a from which allows filtering tests by result, architecture and TODO-status.

![screenshot_20160909_130610](https://cloud.githubusercontent.com/assets/10248953/18385016/3f966b36-768e-11e6-8ee3-fa48dcd0d31d.png)

## Proposals for uses of labels

With [Show bug or label icon on overview if labeled (gh#550)](https://github.com/os-autoinst/openQA/pull/550) it is possible to add custom labels just by writing them. Nevertheless, a convention should be found for a common benefit. Beware that labels are also automatically carried over with (Carry over labels from previous jobs in same scenario if still failing [gh#564])(https://github.com/os-autoinst/openQA/pull/564) which might make consistent test failures less visible when reviewers only look for test results without labels or bugrefs.

List of proposed labels with their meaning and where they could be applied.

* ***`fixed_<build_ref>`***: If a test failure is already fixed in a more recent build and no bug reference is known, use this label together with a reference to a more recent passed test run in the same scenario. Useful for reviewing older builds. Example (https://openqa.suse.de/tests/382518#comments):

```

label:fixed_Build1501

t#382919

```

* ***`needles_added`***: In case needles were missing for test changes or expected product changes caused needle matching to fail, use this label with a reference to the test PR or a proper reasoning why the needles were missing and how you added them. Example (https://openqa.suse.de/tests/388521#comments):

```

label:needles_added

needles for https://github.com/os-autoinst/os-autoinst-distri-opensuse/pull/1353 were missing, added by jpupava in the meantime.

```
