# Test Implementation Plan

## Task 1: Create Hello Function

Create a simple hello function that returns "Hello, World!".

**File:** `src/hello.js`

**Implementation:**
```javascript
export function hello() {
  return "Hello, World!";
}
```

**Tests:** Write a test that verifies the function returns the expected string.

**Verification:** `npm test`

## Task 2: Create Goodbye Function

Create a goodbye function that takes a name and returns a goodbye message.

**File:** `src/goodbye.js`

**Implementation:**
```javascript
export function goodbye(name) {
  return `Goodbye, ${name}!`;
}
```

**Tests:** Write tests for:
- Default name
- Custom name
- Edge cases (empty string, null)

**Verification:** `npm test`
