All About Testing

Different Testing Concepts

• Unit testing: test the smallest piece of code
• Integration testing: test if different components work together
• System testing: test every component of an application to make sure that they work as a complete and unified whole
• Smoke testing: ensure that the critical functions of the program are working
• Regression testing: determine if code modifications break an application
• Performance testing: examines the speed, stability, reliability, scalability, and resource usage of a software application under a specified workload
• Load testing: determines how the software application behaves while being accessed by multiple users simultaneously
• Stress testing: tests beyond normal operational capacity to test the results

More

• White box testing: Know code and structure of the product to be tested and uses that knowledge to perform the tests
• Black box testing: Does not know its internal functioning
