All functionality defined in terraform_compliance directory where all test defined on tests with the same structure. So if you change something in the terraform_compliance/steps, then the tests must exist in tests/steps.

terraform-compliance uses radish for the BDD framework, with lots of extensions written to parse and process terraform files. Most of the functionality is described in

How to write tests

You will usually want to only write functional tests.


├── terraform_compliance
├── docs
└── tests
    └── terraform_compliance (unit tests)
    └── functional (integration tests)
        ├── ...
        └── your_test_directory
	        ├── plan.out.json
	        ├── test.feature
	        └── Dotfiles (optional)


All dotfiles are optional.

  • .failure
    • if this file exists, the test will be expected to fail
  • .expected
    • Expected output. The tests will fail if scenarios in test.feature won’t produce every line (output) in .expected. A common use case is to check if a specific error happens in the test.
  • .unexpected
    • Unexpected output. Similar to .expected, but the test fails if any of the tests produces any of the lines in .unexpected

Updating Website
