We want to provide enough flexibility here so the 'provision' step allows you to choose your preferred way. > My primary environment would be local. So for your case that would be 'provision --how local'. If you have a test box prepared for testing you could also connect to it using 'provision --how connect'. > > Execute tests in my preferred environment: > > > > tmt run --all provision --how container > > tmt run --all provision --how virtual > > tmt run --all provision --how local > > tmt run --all provision --how ... > > I find it difficult to guess what the above commands actually do. > Do they run the tests or do they provision environments to run the > tests? Or both? The 'tmt run' command is used to run tests. By default it runs all steps (discover, provision, prepare, execute, report, finish) so the examples above would run tests in the requested environment. It is also possible to run only selected steps: For example, one of the use cases shared with us was 'just tell me what tests would be run, do not run them', this can be achieved with the following: tmt run discover For detailed description of individual steps have a look here: https://tmt.readthedocs.io/en/latest/spec/steps.html > > I would like to ask for your feedback about this.

Metadata levels allow to store all needed test execution data at appropriate location, the levels are described here: https://tmt.readthedocs.io/en/latest/spec.html We want the config for simple/common use cases (such as running a shell script as a test) as simple as possible so that users do not have to study all the details but just create something like this: execute: script: ./run-my-test.sh If one needs to maintain larger set of tests the L1 metadata can come handy: https://tmt.readthedocs.io/en/latest/spec/tests.html > What are "tiers" for? They are used to organize tests into groups by priority. https://tmt.readthedocs.io/en/latest/spec/tests.html#tier > Which items are mandatory and which are optional? In order to enable tests you just have to define the 'execute' step. Use 'tmt init --template mini' to get a quick start. > What's "relevancy"? It's a test (L1) attribute allowing to filter relevant tests. https://tmt.readthedocs.io/en/latest/spec/tests.html#relevancy Currently we're working on open-sourcing the implementation. > Why is there "extra-summary" in addition to "summary"? > What's "extra-task"? These are because of backward compatibility, for more see: https://tmt.readthedocs.io/en/latest/stories/cli.html?highlight=extra-task#nitrate > What are "plans" for? Plans define which tests should be executed, how the environment should be provisioned and prepared, how the results should be reported. See the following page for more details about plans. https://tmt.readthedocs.io/en/latest/spec/plans.html > What are "stories" for? Stories are an advanced, optional feature which can help you to track which features/requirements have been already implemented, tested and documented. https://tmt.readthedocs.io/en/latest/spec/stories.html https://github.com/psss/tmt/tree/master/stories > You're using a lot of terms as if everyone knows what they mean > in your context. Sorry for that. We're trying to document the concept as best as we can. Hopefully, the links above have helped. Perhaps we could add some more references to the examples page. Thank you for all your feedback. Please, let us know what's still missing and how we can further improve the docs.
