# When to Mock
|
|
|
|
Mock at **system boundaries** only:
|
|
|
|
- External APIs (payment, email, etc.)
|
|
- Databases (sometimes - prefer test DB)
|
|
- Time/randomness
|
|
- File system (sometimes)
|
|
|
|
Don't mock:
|
|
|
|
- Your own classes/modules
|
|
- Internal collaborators
|
|
- Anything you control
|
|
|
|
## Designing for Mockability
|
|
|
|
At system boundaries, design interfaces that are easy to mock:
|
|
|
|
**1. Use dependency injection**
|
|
|
|
Pass external dependencies in rather than creating them internally:
|
|
|
|
```typescript
|
|
// Easy to mock
|
|
function processPayment(order, paymentClient) {
|
|
return paymentClient.charge(order.total);
|
|
}
|
|
|
|
// Hard to mock
|
|
function processPayment(order) {
|
|
const client = new StripeClient(process.env.STRIPE_KEY);
|
|
return client.charge(order.total);
|
|
}
|
|
```
|
|
|
|
**2. Prefer SDK-style interfaces over generic fetchers**
|
|
|
|
Create specific functions for each external operation instead of one generic function with conditional logic:
|
|
|
|
```typescript
|
|
// GOOD: Each function is independently mockable
|
|
const api = {
|
|
getUser: (id) => fetch(`/users/${id}`),
|
|
getOrders: (userId) => fetch(`/users/${userId}/orders`),
|
|
createOrder: (data) => fetch('/orders', { method: 'POST', body: data }),
|
|
};
|
|
|
|
// BAD: Mocking requires conditional logic inside the mock
|
|
const api = {
|
|
fetch: (endpoint, options) => fetch(endpoint, options),
|
|
};
|
|
```
|
|
|
|
The SDK approach means:
|
|
- Each mock returns one specific shape
|
|
- No conditional logic in test setup
|
|
- Easier to see which endpoints a test exercises
|
|
- Type safety per endpoint
