Strategies for Realistic Mock Data

The Danger of "Lorem Ipsum"

Testing your UI with perfect strings like "Test User" masks CSS overflow bugs and unexpected text wrapping. Real data is messy. Names are long, addresses contain unexpected characters, and fields are often null.

Faker Libraries

Tools like Faker.js use deterministic seed values to generate consistent, realistic data. When defining schemas in JSONMock, we use a similar syntax.

Data Type	Why it matters
UUIDs	Ensures unique keys in React lists.
Timestamps	Tests timezone formatting logic in the UI.
Emails	Tests overflow on long domains.
