fix: add missing fix mode options and test cases (#5987)
Browse files Browse the repository at this point in the history
- Add missing fix mode options for: CLANG_FORMAT, ENV,
  GOOGLE_JAVA_FORMAT, NATURAL_LANGUAGE, PYTHON_ISORT, RUST_CLIPPY.
- Refactor linter tests to make them shorter because there's no need to
  have big test files.
- Refactor 'bad' linter tests for linters that support fix mode so they
  contain only automatically fixable issues. This is needed to avoid
  adding another set of 'bad' linter tests for fix mode.
- Provide configuration files for linters that support fix mode and for
  which the default configuration is not suitable to enable fix mode:
  ansible-lint, ESLint, golangci-lint.
- Add a test case for linter commands options for linters that support
  fix mode, to ensure that fix mode and check-only mode options have
  been defined.
- Refactor the fix mode test to check if linters actually applied
  modifications to files.
- Update documentation about adding test cases for linters that support
  fix mode.
- Don't exit with a fatal error if VALIDATE_xxx is false when testing
  fix mode because not all linters support fix mode. To enable this, set
  the new FIX_MODE_TEST_CASE_RUN variable to true.

- If you're running Super-linter locally, you can commit the changes as you
would with any other change in your working directory.

### Fix mode for ansible-lint

ansible-lint requires that the `yaml` rule is enabled to for the ansible-lint
fix mode to work. The default ansible-lint configuration that Super-linter ships
disables the `yaml` rule because it might not be compatible with yamllint. If
you need to enable the ansible-lint fix mode, provide an ansible-lint
configuration that doesn't ignore the `yaml` rule.

### Fix mode file and directory ownership

When fix mode is enabled, some linters and formatters don't maintain the
original file or directory ownership, and use the user that Super-linter uses
to run the linter or formatter.

## Configure linters

Super-linter provides default configurations for some linters in the [`TEMPLATES/`](TEMPLATES/)

If the linter supports fix mode, the test case supposed to fail validation
should only contain violations that the fix mode can automatically fix.
Avoid test cases that fail only because of syntax errors, when possible.
4. If the linter supports check-only mode or fix mode, add the `<LANGUGAGE>`
to the `LANGUAGES_WITH_FIX_MODE` array in `test/testUtils.sh`
