What does "robustness" mean in programming?
robustness is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
The ability of a system to handle errors, unexpected inputs, and edge cases gracefully without crashing. A robust system fails safely and gives meaningful error messages rather than silently producing wrong results.
Example
"The API is robust — it validates all inputs and returns helpful errors instead of crashing on bad data."
