Test Data: 6 Tips for Developers

Tips for working with test data

1. Ensure consistency

The email must match the name: if the name is Ivan Petrov, then the email is ivan.petrov@... Our generator does this automatically.

2. Include edge cases

Add to the test set: empty fields, very long lines, special characters, dates February 29.

3. Don't use real data

Even “anonymized” real data can be de-anonymized. Generate from scratch.

4. Vary the amount of data

Test with 1 record, 100, 10000 and 100000 - system behavior may vary.

5. Consider relationships between data

Orders must refer to existing users, products - to categories. Generate linked data.

6. Automate updates

Test data becomes outdated. Set up the generation script as part of the CI/CD pipeline.
