    Re: Testing Basic

    HI,

    Validation means, Determining if the system complies with the requirements and performs functions for which it is intended and meets the organization’s goals and user needs. It is traditional and is performed at the end of the project.

    Verification means, The review of interim work steps and interim deliverables during a project to ensure they are acceptable. To determine if the system is consistent, adheres to standards, uses reliable techniques and prudent practices, and performs the selected functions in the correct manner.

    Re: Testing Basic

    Verification - evaluating a system (during the development process) to find weather the results of a given phase (in SDLC) satisfy the conditions imposed on it at the start of that phase.

    Quality Assurance = Verification

    Validation - evaluating a system (during or after the development process as in most cases) to find weather it satisfies specified requirements.

    Quality Control = Validation = Testing

    Lack of WILL POWER has caused more failure than
    lack of INTELLIGENCE or ABILITY.

    Re: Testing Basic

    Verification evaluates documents, plans, code, requirements, and specifications. Validation, evaluates the product itself.
    Validation is done during actual testing and it takes place after all the verifications are being done.

    Re: Validation and Verification

    Verification is a complete documention of expected requirements.

    Validation is a process of something checking True or False, also based on verification.

    I am not sure of static testing and verification is dynamic testing

    Verification is to ensure that “we are building the product right”.

    Dear friend "verification is static testing" and "validation is dynamic testing".

    In static testing we did reviews.
    In dynamic we execute test cases on working build.

    I think you got it.
