Definition of the environment context

As a user I want to define a context so that test, plan or story metadata can be adjusted to it accordingly.

This specification defines all standard context dimensions which can be used together with the adjust attribute to modify object metadata for particular context. For a detailed description of the concept itself see the fmf context documentation.

The context is usually defined from the command line using the --context option. All dimensions are optional. It is possible to define your own dimensions to describe the context, just make sure the dimension name does not conflict with reserved names.

Some of the context dimensions can be detected (e.g. distro from the provision step config). Each plan can provide its own context which will override detected values. Finally, the context definition provided directly on the command line overrides detected and defined dimensions.


tmt --context distro=fedora-33 run
tmt --context product=rhscl run
tmt --context trigger=code run

tmt -c distro=fedora test show
tmt -c distro=fedora plan show


Supported context dimensions

As a tester I want to clearly specify dimensions, such as ‘distro’ or ‘trigger’, so that I can well describe the context in which a test is running.

The following dimensions are reserved for storing dedicated information as described below:

The operating system distribution on which the application runs (fedora, fedora-33, centos, centos-8, centos-8.4, rhel, rhel-8, rhel-8.4).
The distribution variant (Client, Desktop, Server Workstation, Silverblue, CoreOS).
The guest architecture (aarch64, armhfp, i386, ppc64, ppc64le, s390x, x86_64).
Name of the relevant component, should match the source package name (bash, php, httpd).
The Red Hat Software Collection name (python27, rh-python34, rh-mariadb100, httpd24).
Module name with an optional stream specification (mariadb, mariadb:10.5, httpd, httpd:2.4, perl, perl:5.32, ruby, ruby:2.7).
The event which triggered testing, see the trigger section for the full list of supported values.


    distro: fedora-33
    variant: Workstation
    arch: x86_64

    product: rhscl
    collection: httpd24

Status: implemented


Definition of the trigger dimension

As a user I want to run a custom set of tests for different events which trigger the testing.

Testing can be triggered by various events and a different set of tests is usually executed for each of them. The trigger dimension supports the following values:

Project source code has changed. This can be either a pull/merge request or a new commit pushed to a branch.
There has been a new package built in koji or brew and is available for testing.
A new bodhi update or errata advisory with one or more builds has been created or updated.
There is a new compose ready for integration testing.

This context dimension will usually be provided from the command line.
