+# Introduction CI Testing Plans
+
+Linux System Roles CI runs [tmt](https://tmt.readthedocs.io/en/stable/index.html) test plans in [Testing farm](https://docs.testing-farm.io/Testing%20Farm/0.1/index.html) with the [tft.yml](https://github.com/linux-system-roles/network/blob/main/.github/workflows/tft.yml) GitHub workflow.
+
+The `plans/test_playbooks_parallel.fmf` plan is a test plan that runs test playbooks in parallel on multiple managed nodes.
+`plans/test_playbooks_parallel.fmf` is generated centrally from `https://github.com/linux-system-roles/.github/`.
+The automation calculates the number of managed nodes to provision with this formula:
+
+```plain
+number-of-test-playbooks / 10 + 1
+```
+
+The `plans/test_playbooks_parallel.fmf` plan does the following steps:
+
+1. Provisions systems to be used as a control node and as managed nodes.
+2. Does the required preparation on systems.
+3. For the given role and the given PR, runs the general test from [test.sh](https://github.com/linux-system-roles/tft-tests/blob/main/tests/general/test.sh).
+
+The [tft.yml](https://github.com/linux-system-roles/network/blob/main/.github/workflows/tft.yml) workflow runs the above plan and uploads the results to our Fedora storage for public access.
+This workflow uses Testing Farm's Github Action [Schedule tests on Testing Farm](https://github.com/marketplace/actions/schedule-tests-on-testing-farm).
+
+## Running Tests
+
+You can run tests locally with the `tmt try` cli or remotely in Testing Farm.
+
+### Running Tests Locally
+
+1. Install `tmt` as described in [Installation](https://tmt.readthedocs.io/en/stable/stories/install.html).
+2. Change to the role repository directory.
+3. Modify `plans/test_playbooks_parallel.fmf` to suit your requirements:
+    1. Due to [issue #3138](https://github.com/teemtee/tmt/issues/3138), comment out all managed nodes except for one.
+    2. Optionally modify environment variables to, e.g. run only specified test playbooks by modifying `SYSTEM_ROLES_ONLY_TESTS`.
+4. Enter `tmt try -p plans/test_playbooks_parallel <platform>`.
+    This command identifies the `plans/test_playbooks_parallel.fmf` plan and provisions local VMs, a control node and a managed node.
+5. `tmt try` is in development and does not identify tests from URL automatically, so after provisioning the machines, you must type `t`, `p`, `t` from the interactive prompt to identify tests, run preparation steps, and run the tests.
+
+### Running in Testing Farm
+
+1. Install `testing-farm` as described in [Installation](https://gitlab.com/testing-farm/cli/-/blob/main/README.adoc#user-content-installation).
+2. Change to the role repository directory.
+3. If you want to run tests with edits in your branch, you need to commit and push changes first to some branch.
+4. You can uncomment "Inject your ssh public key to test systems" discover step in the plan if you want to troubleshoot tests by SSHing into test systems in Testing Farm.
+5. Enter `testing-farm request`.
+    Edit to your needs.
+
+    ```bash
+    $ TESTING_FARM_API_TOKEN=<your_api_token> \
+        testing-farm request --pipeline-type="tmt-multihost" \
+        --plan-filter="tag:playbooks_parallel" \
+        --git-url "https://github.com/<my_user>/network" \
+        --git-ref "<my_branch>" \
+        --compose CentOS-Stream-9 \
+        -e "SYSTEM_ROLES_ONLY_TESTS=tests_default.yml" \
+        --no-wait
+    ```
