Test Automation is the use of software to control the execution of tests, the comparison of actual outcomes to predicted outcomes, the setting up of test preconditions, and other test control and test reporting functions. Commonly, test automation involves automating a manual process already in place that uses a formalized testing process.
Many test automation tools provide record and playback features that allow users to record interactively user actions and replay it back
Types of Test Automation
Functional testing
Functional testing is testing conducted on a complete, integrated system to evaluate the system's compliance with its specified requirements. System testing falls within the scope of black box testing, and as such, should require no knowledge of the inner design of the code or logic.
Tools
Performance Testing
Performance Testing is testing that is performed, from one perspective, to determine how fast some aspect of a system performs under a particular workload. It can also serve to validate and verify other quality attributes of the system, such as scalability and reliability.
demonstrate that the system meets performance criteria.
impossible to exactly replicate this workload variability of a real time system
Tools
Stress Testing/Load Testing
Stress Testing is a form of testing that is used to determine the stability of a given system or entity. It involves testing beyond normal operational capacity, often to a breaking point, in order to observe the results. Stress testing may have a more specific meaning in certain industries.
stress testing often refers to tests that put a greater emphasis on robustness, availability, and error handling under a heavy load, than on what would be considered correct behavior under normal circumstances.
Load Testing is the process of creating demand on a system or device and measuring its response.
Load testing generally refers to the practice of modeling the expected usage of a software program by simulating multiple users accessing the program's services concurrently.
