Test Management Tool
Test Management Tool
The tmt tool provides a user-friendly way to work with tests. You can comfortably create new tests, safely and easily run tests across different environments, review test results, debug test code and enable tests in the CI using a consistent and concise config.
The python module and command-line tool implement the Metadata Specification which allows storing all needed test execution data directly within a git repository. Together with possibility to reference remote repositories it makes it easy to share test coverage across projects and distros.
The Flexible Metadata Format fmf is used to store data in both human and machine readable way close to the source code. Thanks to inheritance and elasticity metadata are organized in the structure efficiently, preventing unnecessary duplication.
There are several metadata levels defined by the specification:
Core attributes such as summary or description which are common across all levels are defined by the special L0 metadata.
Tests, or L1 metadata, define attributes which are closely related to individual test cases such as test script, framework, directory path where the test should be executed, maximum test duration or packages required to run the test.
Plans, also called L2 metadata, are used to group relevant tests and enable them in the CI. They describe how to discover tests for execution, how to provision the environment, how to prepare it for testing, how to execute tests and report test results.
Stories, which implement the L3 metadata, can be used to track implementation, test and documentation coverage for individual features or requirements. Thanks to this you can track everything in one place, including the project implementation progress.
Command line usage is straightforward:
tmt command [options]
Let’s see which tests, plans and stories are available:
tmt
Initialize the metadata tree in the current directory, optionally with example content based on templates:
tmt init tmt init --template base
Run all or selected steps for each plan:
tmt run tmt run discover tmt run prepare execute
List tests, show details, check against the specification:
tmt test ls tmt test show tmt test lint
Create a new test, import test metadata from other formats:
tmt test create tmt test import
List plans, show details, check against the specification:
tmt plan ls tmt plan show tmt plan lint
List stories, check details, show coverage status:
tmt story ls tmt story show tmt story coverage
Many commands support regular expression filtering and other specific options:
tmt story ls cli tmt story show create tmt story coverage --implemented
Check help message of individual commands for the full list of available options.
Here is the list of the most frequently used commands and options.
The run command is used to execute test steps. By default all test steps are run. See the L2 Metadata specification for detailed description of individual steps. Here is a brief overview:
Gather information about test cases to be executed.
Provision an environment for testing or use localhost.
Prepare the environment for testing.
Run tests using the specified executor.
Provide test results overview and send reports.
Perform the finishing tasks and clean up provisioned guests.
Manage tests (L1 metadata). Check available tests, inspect their metadata, gather old metadata from various sources and stored them in the new fmf format.
List available tests.
Show test details.
Check tests against the L1 metadata specification.
Create a new test based on given template.
Convert old test metadata into the new fmf format.
Manage test plans (L2 metadata). Search for available plans. Explore detailed test step configuration.
List available plans.
Show plan details.
Check plans against the L2 metadata specification.
Manage user stories. Check available user stories. Explore coverage (test, implementation, documentation).
List available stories.
Show story details.
Show code, test and docs coverage for given stories.
Export selected stories into desired format.
Various utility options.
Path to the metadata tree, current directory used by default.
Print additional information.
Turn on debugging output.
Check help message of individual commands for the full list of available options.
The main tmt package provides the core features with a minimal set of dependencies:
sudo dnf install tmt
In order to enable additional functionality, such as particular provision or report plugins, install the respective subpackage:
sudo dnf install tmt-test-convert sudo dnf install tmt-report-html sudo dnf install tmt-provision-container sudo dnf install tmt-provision-virtual
If you don’t care about disk space and want to have all available features right at hand install everything:
sudo dnf install tmt-all
For RHEL 8 and CentOS 8, first make sure that you have available the EPEL repository:
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm sudo dnf install tmt
For plugins which cannot work outside of VPN and so live within its walls you need to enable the internal copr repository first. Then you can install either everything or only those you need:
sudo dnf install tmt-redhat-all sudo dnf install tmt-redhat-*
Impatient to try the fresh features as soon as possible? Install the latest greatest version from the copr repository:
sudo dnf copr enable psss/tmt sudo dnf install tmt
Not sure, just want to try out how it works? Experiment safely and easily inside a container:
podman run -it --rm quay.io/testing-farm/tmt bash podman run -it --rm quay.io/testing-farm/tmt-all bash
When installing using pip you might need to install additional packages on your system:
sudo dnf install gcc {python3,libvirt,krb5,libpq}-devel
pip install --user tmt
Note: You can omit the --user flag if in a virtual environment.
The rpm package includes a system wide script which enables the command line completion for bash so no additional config should be needed. If you use a different installation method or prefer another shell, see the instructions below.
For Bash, add this to ~/.bashrc:
eval "$(_TMT_COMPLETE=source_bash tmt)"
For Zsh, add this to ~/.zshrc:
eval "$(_TMT_COMPLETE=source_zsh tmt)"
For Fish, add this to ~/.config/fish/completions/tmt.fish:
eval (env _TMT_COMPLETE=source_fish tmt)
Open a new shell to enable completion. Or run the eval command directly in your current shell to enable it temporarily.
The following exit codes are returned from tmt run. Note that you can use the --quiet option to completely disable output and only check for the exit code.
At least one test passed, there was no fail, warn or error.
There was a fail or warn identified, but no error.
Errors occured during test execution.
No test results found.
The following environment variables can be used to modify behaviour of the tmt command.
Enable the desired debug level. Most of the commands support levels from 1 to 3. However, some of the plugins go even deeper when needed.
Disable colors in the terminal output. Output only plain, non-colored text. See https://no-color.org/ for more information.
