+# clang tests
+
+This repository contains tests for clang.
+
+## Usage
+Tests are executed using TMT (Test Management Tool). The repository includes a
+TMT plan that runs all the tests by default. All the tests support the following
+context dimensions:
+
+* `distro`
+* `arch`
+* `collection` (only applicable to RHEL 7)
+
+To run the tests:
+```bash
+# Run in the default virtual environment
+tmt -c distro=<distro> -c arch=<arch> run -avv
+
+# Run on a scheduled system
+tmt -c distro=<distro> -c arch=<arch> run -avv provision -h connect -g <ip_or_hostname>
+
+# Run specific tests
+tmt -c distro=<distro> -c arch=<arch> run -avv provision -h connect -g <ip_or_hostname> test -n <regex>
+```
+
+## Adding New Tests
+Please consider the following when adding new tests:
+
+* Test scripts must be named `runtest.sh`. If a different test is needed, you need
+to overwrite the `test:` key in the test `main.fmf`.
+* Tests must be placed under `tests/<test_name>`. Additionally they can be
+  placed into subdirectories if grouping make sense. E.g.
+  `tests/regression/<test_name>`.
+* This repository has a common configuration under `tests/main.fmf`, inherited
+  by all tests. When adding new ones, be careful not to overwrite existing keys
+  from the inherited `tests/main.fmf`.
+* When setting FMF metadata keys, do merge values instead overwriting them. E.g.
+use `require+:` instead `require:`. For advanced use and more examples check
+[FMF documentation](https://fmf.readthedocs.io/en/stable/features.html#merging).
+
+After creating the new test, consider running `tmt <context> tests show
+<test-name>` to review that the resulting metadata such as requires, enable or
+test keys are as expected. For example:
+```
+$ tmt -c distro=fedora-38 tests show ucrt64-toolchain
+/tests/ucrt64-toolchain
+                 summary Test that ucrt64 toolchain is detected
+                 contact Jesus Checa Hidalgo <jcheca@redhat.com>
+               component 'llvm-toolset' and 'clang'
+                    test ./runtest.sh
+                    path /tests/ucrt64-toolchain
+               framework shell
+                  manual false
+                     tty false
+                 require 'ucrt64-gcc-c++' and 'clang'
+                duration 5m
+                 enabled true
+                  result respect
+
+$ tmt -c distro=rhel-9.3 tests show ucrt64-toolchain
+/tests/ucrt64-toolchain
+                 summary Test that ucrt64 toolchain is detected
+                 contact Jesus Checa Hidalgo <jcheca@redhat.com>
+               component 'llvm-toolset' and 'clang'
+                    test ./runtest.sh
+                    path /tests/ucrt64-toolchain
+               framework shell
+                  manual false
+                     tty false
+                 require 'ucrt64-gcc-c++' and 'clang'
+                duration 5m
+                 enabled false
+                  result respect
+```
+
+### Templates
+Use the following templates when creating new tests.
+
+FMF template. Uncomment needed fields, remove the rest.
+```yaml
+summary: Descriptive summary for the test
+# Maximum duration for the test
+duration: 2m
+# Short tests should be tier <= 1 so they're used for gating.
+tier: 1
+# Add an additional contact(s) if applicable
+# contact+:
+#   - Somebody <somebody@redhat.com>
+# Additional requires
+# require+:
+#   - rpm-build
+# Adjustments based on context dimensions
+# adjust+:
+#   - when: collection is defined
+#     enabled: false
+#     because: Test not supported in collections
+# link+:
+#   - verifies: https://issues.redhat.com/browse/...
+# tag+:
+#   - sometag
+```
+
+### Avoid common errors using pre-commit
+
+This project uses [`pre-commit`](https://pre-commit.com/)
+
+* to [lint fmf files](https://tmt.readthedocs.io/en/latest/guide.html#lint)
+* to check that you don't have [trailing
+  whitespaces](https://github.com/pre-commit/pre-commit-hooks?tab=readme-ov-file#trailing-whitespace)
+* to check that [files end with a
+  newline](https://github.com/pre-commit/pre-commit-hooks?tab=readme-ov-file#end-of-file-fixer)
+
+Please install `pre-commit` using `pip install pre-commit` as described
+[here](https://pre-commit.com/#install). Then navigate to your clone of this
+project and install the git hook scripts using `pre-commit install`. This will
+run pre-commit on every `git commit` that you make in this repository from now
+on.
+
+## Test specific documentation
+
+### kernel-ark-rebuild
+The `kernel-ark-rebuild` test is a special test that we use to ensure that clang,
+llvm, and lld builds do not break [Always Ready Kernel](
+https://gitlab.com/cki-project/kernel-ark) builds, which are done in Fedora
+Rawhide. This is a virtual test comprised of 4 tests corresponding to different
+build configurations for the kernel:
+
+* base
+* base/lto
+* debug
+* debug/lto
+
+Due to this, this test is not regularly run on PRs opened in tests/clang, as
+running the 4 tests can take about 6 hours. Instead, if you modify the test
+you are expected to run it on your own and provide the results in the Pull
+Request. A specific tmt test plan named `kernel-ark-gating.fmf` is provided for
+that. It can be run using Testing Farm with this command:
+```
+testing-farm request -c initiator=human -c distro=fedora-rawhide -c arch=<your-arch> \
+    --compose Fedora-Rawhide --git-url <url-to-your-fork> --git-ref <your-pr-branch> \
+    --plan kernel-ark-gating
+```
+You need an [API key](https://docs.testing-farm.io/Testing%20Farm/0.1/onboarding.html)
+to be able to use Testing Farm. If you don't have on, please ask for help running
+the test when opening a Pull Request.
