# Kubeval Test Cases
This folder holds the test cases for **Kubeval**.
## Additional Docs
No Additional information is needed for this test case.
## Good Test Cases
The test cases denoted: `LANGUAGE_good_FILE.EXTENSION` are all valid, and should pass successfully when linted.
- **Note:** They are linted utilizing the default linter rules.
## Bad Test Cases
The test cases denoted: `LANGUAGE_bad_FILE.EXTENSION` are **NOT** valid, and should trigger errors when linted.
- **Note:** They are linted utilizing the default linter rules.
