验证和确认之间的差异

先决条件 - 验证和确认
验证是检查软件是否在没有任何错误的情况下实现其目标的过程。它是确保开发的产品是否正确的过程。它验证开发的产品是否满足我们的要求。验证是静态测试。
验证意味着我们是否在构建产品？

验证是检查软件产品是否符合标准或换句话说产品是否具有高水平要求的过程。这是检查产品验证的过程，即检查我们正在开发的产品是否正确。它是对实际产品和预期产品的验证。验证是动态测试。
验证意味着我们是否在构建正确的产品？

验证和验证之间的区别如下：

Verification	Validation
It includes checking documents, design, codes and programs.	It includes testing and validating the actual product.
Verification is the static testing.	Validation is the dynamic testing.
It does not include the execution of the code.	It includes the execution of the code.
Methods used in verification are reviews, walkthroughs, inspections and desk-checking.	Methods used in validation are Black Box Testing, White Box Testing and non-functional testing.
It checks whether the software conforms to specifications or not.	It checks whether the software meets the requirements and expectations of a customer or not.
It can find the bugs in the early stage of the development.	It can only find the bugs that could not be found by the verification process.
The goal of verification is application and software architecture and specification.	The goal of validation is an actual product.
Quality assurance team does verification.	Validation is executed on software code with the help of testing team.
It comes before validation.	It comes after verification.
It consists of checking of documents/files and is performed by human.	It consists of execution of program and is performed by computer.
