Profile picture for user dgulati

Alpha Testing: Alpha testing is one of the type of acceptance testing performed to identify all the bugs before releasing the product to clients/stakeholders or everyday users or public. It is done early on near the end of development but before release to clients. Focus of this testing simulates all real users for Black box and White box testing techniques. Alpha testing is conducted in virtual environment/lab environment or at developer’s site.

Beta Testing: Beta testing is the next phase of software testing after alpha testing and is performed by real users or clients of software application in real environment. It is done just after alpha testing in live environment in which developers are not present and done at client’s site only. It is final test just before shipping final product to stakeholders. It allows customers to provide any feedback, modifications which are important for the success of the product.
