What are the differences between system and functional testing?- System testing has classifications like functional and non functional testing. Hence the functional testing is a part of system testing.
- System testing allows the testers to test the typical end product. Every single module, interface and every minute detail are needed to be tested in system testing.
- Functional testing is aimed at testing the functionalities of the product being tested. These functionalities include volume, stress, load, security, scalability, performance etc. Hardware and software is not concerned with functional testing.
- Functional testing involves testing of functional requirements as per the specification. On the other hand, system testing involves testing the system as a whole. This may involve testing of proper installation and uninstalling of the application. System testing tests for all internal and external components that make the system.
