### Introduction

In this document, we will explore the Cerbos policy testing framework, which provides a structured way to define and execute tests against your policy definitions.

### Test Suite Structure

A typical test suite consists of several key components:

- **Name**: A unique identifier for the test suite.
- **Description**: A brief overview of the test suite's purpose.
- **Principals**: A collection of entities that will be tested against the policies.
- **Resources**: The entities on which actions will be performed.
- **Tests**: Individual tests defined within the suite, each specifying inputs and expected outputs.

### Example Test Table

#### Test Table Structure

Each test table includes:

- **Name**: Unique name for the test.
- **Input**: Test input data specifying principals, actions, and resources.
- **Expected**: The expected outcomes of the test.

#### Sample Test Table

```json
{
  "name": "Sample Test",
  "input": {
    "principals": ["user123"],
    "actions": ["read"],
    "resources": ["resourceA"]
  },
  "expected": [
    {
      "principal": "user123",
      "resource": "resourceA",
      "actions": {
        "read": "EFFECT_ALLOW"
      }
    }
  ]
}
```

### Conclusion

Utilizing this structured framework allows for robust testing of your policies, ensuring that they behave as expected.
