Test definition survey

Here is a list of test definition fields, attributes, file formats, operations, instructions, functions, etc. (I won't know what even what they consist of until I see them).

This is the object in your test system that "defines" what a test is. It likely has meta-data about the program to run, how to get the program started, maybe what things are required for the program to run, how the results should be interpreted, etc.

= Test definition data survey = Each sub-section below has data about test definitions from a different system.

For many, there are links to the test definitions for that system: One simple, one characteristic, and link to repository containing lots of them.

Also, each sub-section has data that describes the files, fields and usage of the different fields in that system.

LAVA

 * (simple) busybox: https://github.com/Linaro/test-definitions/tree/master/automated/linux/busybox
 * (another simple) mmc: https://github.com/Linaro/test-definitions/tree/master/automated/linux/mmc

 * (repository) https://github.com/Linaro/test-definitions/

For the 'files' part, each test in test-definitions is stored in a separate directory. The directory has to contain at least the YAML file that is compliant with LAVA test definition. We have a sanity check script (validate.py) that is executed on any pull request. This ensures all files pushed to the repository are compliant. Usual practice is that test directory contains a test script (shell script). The test script is responsible for installing dependencies, running tests and parsing results. There is no mandatory format there but test-definitions provides a library of functions that help writing test scripts. There are libraries for 'linux' and 'android'. We also host directory for manual tests and simple executor for them but in the context of automated testing these are irrelevant.

Yocto Project
An "on target" test of the compiler:

(same directory has simple python/perl tests and so on)
 * (simple) gcc: http://git.yoctoproject.org/cgit.cgi/poky/tree/meta/lib/oeqa/runtime/cases/gcc.py

http://git.yoctoproject.org/cgit.cgi/poky/tree/meta/lib/oeqa/files (for the test files for context, they're just hello world examples)

This is a "selftest" for the "devtool" command that is part of the overall build system, its a bit more complex with shared functions and tests for each of devtool's subcommands.
 * (characteristic) devtool: http://git.yoctoproject.org/cgit.cgi/poky/tree/meta/lib/oeqa/selftest/cases/devtool.py

This has all the test code and core test definitions. Test definitions are in cases directories under "manual", "runtime", "sdk" and "selftest" directories.

CKI

 * (simple) example: https://github.com/CKI-project/tests-beaker/tree/master/example
 * (characteristic) acpitable: https://github.com/CKI-project/tests-beaker/tree/master/acpi/acpitable
 * (characteristic+) ltp-lite: https://github.com/CKI-project/tests-beaker/tree/master/distribution/ltp/lite
 * (repository) https://github.com/CKI-project/tests-beaker/tree/master

Note that CKI is built on top of 'beaker', which is a RedHat project that performs board management and provisioning services, and actually invokes the tests.

See more about the beaker meta-data here: https://beaker-project.org/docs/user-guide/task-metadata.html

files

 * makefile
 * README.md
 * runtest.sh

Each makefile has targets: run, build, clean

Regarding the runtest.sh file, Veronika writes: You don't need to put all code you use into a single runtest files, you can have helper scripts in the test directory (which is the case with xfstests you mentioned) you call. You can also use common libraries that will be installed together with the test (from different place) using the RhtsRequires clause.

fields
Some explanation about 'Requires': People sometimes put in more info into the test meta-data than the "required" fields suggest. In some cases this can be a residue of RHTS (Beaker predecessor) and copy pasting as Beaker is still compatible with it, in other cases they simply use some less known features or just go all out in writing the makefiles.

LTP
Currently (as of September 2019), LTP has test meta-data inside the C files.

Test descriptions for each testcase are in comments in the C code.

Test dependencies are expressed inside the C file for each test, in the tst_test structure. For example needs_root is expresses there, as well as min_kver.

LTP has a new metadata project that is under construction, which generates data in json format for each test, based on the tst_test structure and structured comments.

See https://github.com/metan-ucw/ltp/tree/master/docparse

kselftest
Config fragments are called 'config' and are in each testing area's top-level directory.

Kees Cook just submitted a patch to introduce a file called 'settings' in the top-level directory for each testing area, which currently holds a field called 'timeout'. See https://lore.kernel.org/linux-kselftest/201909191359.1BFD926842@keescook/T/#t

 * Makefile
 * config
 * settings

fields

 * timeout (proposed, as of 9/2019)
