What is concurrency testing?

Concurrency testing is a type of software testing that checks the performance of software when multiple users are logged in and perform actions simultaneously. Hence, it is also referred to as multi-user testing.

Concurrency testing is challenging to conduct compared to sequential testing, due to the following three problems:

• synchronization problems

• non-determinism

• time-related defects difficult to detect

Concurrency testing mainly monitors the system for deadlocking, locking, and single-threaded code.

Concurrent testing methods

Some common methods for performing concurrency testing include the following:

• Fuzz Test: The tester inserts incorrect random data and monitors the system’s response.

• Random Test: Multiple strands are tested simultaneously by randomizing the test inputs.

• Code Review: The testers verify the code and its structures.

• Static Analysis: The tester checks the coding system before the code’s execution.
