Concurrency Testing
Concurrency testing is a software testing technique used to evaluate how an application behaves when multiple users, threads, processes, or transactions execute at the same time. It is designed to detect issues such as race conditions, deadlocks, resource contention, data corruption, and inconsistent state changes that may not appear during single-user or sequential execution. Concurrency testing is commonly applied to distributed systems, databases, APIs, and multithreaded applications.
