Thread Testing Techniques

Thread Testing: Types, Strategy & Multithreading

Thread testing is a testing technique to verify the key functionalities of a task. Thread testing is usually done at early stage of Integration Testing phase. Thread testing is also known as “Thread interaction test.

 

Types of Thread Testing

Single thread testing: A single thread testing means testing one application transaction at a time. Single thread testing is sequential in nature. Each transaction runs after previous is finished its working.

Multithreaded testing: A multithreaded testing means several concurrently active transaction running at a time. Multithreaded testing is parallel in nature. Multiple threads run in parallel using the same code.
 

Need for Multi-threaded Code

Multi-threading technique is used by developers to enhance the performance of the system where the system is interacting with another system in terms of the session or where there is any dependency.

Multithreading is used when:

1. Multiple actions need to be performed at same time.

2. Resources are limited. For e.g. Servers.
    

Tips for Multithreaded Testing

1. The multi-threaded code should be executed again and again on the different types of applications running.

2. The multi-threaded code should be run with multiple instances of program active at same time.

3. The multi-threaded code should be run on different hardware models having different stress levels and workloads.

4. Error and failures occurred in threads should be monitored properly.

Challenges in thread Testing

1. Writing unit tests for multithreaded code is a challenging task

2. Testing criteria for multithreaded testing are different than single thread testing. For multithreaded testing, various factors like memory size, storage capacity, timing problems, etc. varies when called on different hardware.
