The Essential Guide As software developers and QA engineers. We often need to test our applications and systems with realistic-looking phone numbers. Whether it’s validating phone number input fields, ensuring proper formatting and masking, or testing call forwarding and other telephony features, having a reliable set of test phone numbers is crucial.
In this comprehensive guide, we’ll explore the various types of phone numbers available for testing purposes, their use cases, and best practices for incorporating them into your testing workflows.
