# Uniform Show Endpoints Testing

This document describes the testing strategy and execution for ensuring all API `show` endpoints follow a uniform response structure.

## Requirement

All `show` endpoints (e.g., `/api/location/1`, `/api/patient/1`, etc.) must return:
1.  **A single Object** (associative array) in the `data` field when a record is found.
2.  **Null** in the `data` field when a record is not found.

Previously, some endpoints returned a sequential array with one item, which was inconsistent for frontend development.

## Test Suite

The test suite is located at: `tests/feature/UniformShowTest.php`

### What it tests:
- **`testShowEndpointsReturnObjectWhenFound`**: Iterates through a list of known endpoints and verifies that if data is returned, it is an associative array (object) and not a sequential array.
- **`testShowEndpointsReturnNullWhenNotFound`**: Iterates through endpoints with non-existent IDs and verifies that the `data` field is strictly `null`.

## How to Run

Ensure your test database is configured in `phpunit.xml` or `.env`.

Run the following command from the project root:

```bash
vendor/bin/phpunit tests/feature/UniformShowTest.php
```

## Maintenance

If you add a new resource with a `show` method, add its endpoint to the `$endpoints` array in `tests/feature/UniformShowTest.php` to ensure it remains compliant with the uniformity requirement.
