Validation is done at the end of the development process and takes place after verification process is completed. According to CMM we can also define it as the process of evaluating software during or at the end of the development process to determine whether it satisfies specified requirements.
User Acceptance Testing
What are the significant differences between a laboratory assistant and a laboratory technician? The significant differences between a Laboratory assistants and laboratory technicians are types of work they perform and their level of education. Laboratory assistants generally hold associate degree and perform basic testing procedures and conduct fluid analysis in order to diagnose a patient. They also involves in quality control, data entry, filing, and database administration. Laboratory technicians carry out routine laboratory tests and perform a variety of technical support functions to help scientists, technologists and others with their work. They can work in research and development, scientific analysis and testing, education and manufacturing. Generally laboratory technicians hold higher degree than laboratory assitant.
White box testing or unit testing: To do white box testing, knowledge of internal logic code is required. It is mostly done by developers.Black box testing: The functionality of an application is tested; logic code is not required. This testing is done by testers.Block box or system testing: Testing the application without knowledge of underline code of the application. it is done by the testers.
Standard testing is more so based on judgment and can be adjusted through validation. Benchmark testing is multiple criteria for judging success.
verification: Are we doing the right system? validation : Are we doing the system right?
Alpha testing is always performed by the developers at the software development site. acceptance testing is a test conducted to determine if the requirements of a specification or contract are met.

validation
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.
in system level stage field level validation down.
Hi All, I think the answer for this question is, Testing method :Verification(review) and Validation Testing types : Basically static and dynamic-> in dynamic testing further can be classified into structural(white box) and functional(black box) testing Testing Technique : in white box testing we have 1) loop coverage 2)statement coverage 3) condition coverage 4) decision coverage in black box testing we have 1) Equilance partioning, 2)boundary value analysis 3) error guessing Testing Levels : Unit testing, integration testing systemtesting , Acceptance testing
Red Box testing is referred to as Acceptance Testing.

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.
Qualification is the process of demonstrating that an instrument or equipment is properly installed and can perform effectively within predetermined specifications. Validation is the process of evaluating and documenting that a system, process, or method consistently produces results meeting predetermined acceptance criteria. Qualification focuses on the equipment, while validation focuses on the entire process.
