Thread testing is defined as a software testing type, which verify the key functional capabilities of a specific task(thread). It is usually conducted at the early stage of Integration Testing phase.
Thread based testing is one of the incremental strategies adopted during System Integration Testing. That’s why, thread test should probably more properly be called a “thread interaction test.”
Types of Thread Testing
Thread based testing are classified into two categories
Single thread testing: A single thread testing involves one application transaction at a time
Multi-thread testing: A multi-thread testing involves several concurrently active transaction at a time
How to do Thread Testing
The thread process focuses on the integration activities rather than the full development lifecycle. For Example,
Thread-based testing is a generalized form of session-based testing, in that sessions are a form of thread, but a thread is not necessarily a session.
For thread testing, the thread or program (small functionality) are integrated and tested incrementally as a subsystem, and then executed for a whole system.
At the lowest level, it provided integrators with better knowledge of the scope of what to test
Rather than testing software components directly, it required integrators to concentrate on testing logical execution paths in the context of the entire system.
Tips for Multithread Testing
Test your multithreaded program by executing it repeatedly with a different mix of applications running
Test your multithreaded program by having multiple instances of the program active at the same time
Execute your multithreaded program on different hardware models with varying stress levels and workloads
Code inspection
Only collect errors and failures that occurred in threads other than the main one
Disadvantages of Thread Testing
For multithreading testing, the biggest challenge is that you should be able to program reproducible test for unit test
Writing unit tests for multithreaded code is a challenging task
Testing criteria for multi-thread testing are different than single thread testing. For multithread testing various factors like memory size, storage capacity, timing problems, etc. varies when called on different hardware.
