Validation testing is to test software if it meets its stated requirements. System testing is the testing of Software and Hardware together and to find out they both can work together to be successful application.
Functional testing is part of system testing. Functional testing is nothing but testing the system based on its functional behaviour.
system testing is process of testing entire system to verify that it meets specified requirements.
system testing is of two types
1) functional system testing
2) non-functional system testing
verification: Are we doing the right system? validation : Are we doing the system right?
in system level stage field level validation down.

In mission critical systems, especially when software is involved, system-level testing is required to be sure the system/software operates correctly. This is often called Verification & Validation. The two are related, but verification is concerned with testing the system functions against the requirements document (which is essential in a critical system). Each requirement should be testable, and all requirements should be tested. Validation is the process of testing that the system and software behaves as it should when interacting with other systems and components. Verification & Validation is a long, tedious, and expensive process but is essential for mission-critical systems such as where human life or large investment or one-of-a-kind technology is at risk.
software is process to finding error ,bugs and validation against requirement.testing involves operation of the system.
1.Static testing involves verification of activities of the developed software where as dynamic testing involves working with the software, giving input values and checking if the output is as expected. 2.Review's, Inspection's and Walkthrough's are static testing methodologies.Unit Tests, Integration Tests, System Tests and Acceptance Tests are few of the Dynamic Testing methodologies. 3.Static testing is done before the code deployment (verification stage) where as dynamic testing is done after code deployment(validation stage). 4.Static testing is more cost effective then dynamic testing.
What is design validation in quality management system
difference between farming system and cropping system
difference between operating system and system software?
Qualification: A documented testing that demonstrates with a high degree of assurance that a specific process will meet its pre-determined acceptance criteria. Validation: A documented testing, performed under highly controlled conditions, which demonstrates a process consistently produces a result meeting pre- determined acceptance criteria While qualification is used to provide a high degree of assurance that a process is replicable under anticipated variable ranges, validation is used to describe how a system will perform under highly controlled conditions. Based on the definitions above, it is easy to see how these definitions are interchanged. However, the key difference is determined by whether or not the process under review operates under 'highly controlled' conditions. Answerd By S.K. Karimullah PharmEvo, Karachi, Pakistan
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.
