Software Testing Infographic

Beta testing is used to validate a product’s compatibility, reliability, usability and functionality. Users (known as beta testers) will be testing the product (that is 80% to 95% completed) in a real-time environment and then provide their valuable feedback about what they like and did not like about the product. 

Most of the testing strategies depend on regression and functional testing. Applying functional and regression testing in an Agile and DevOps environment needs a strategic approach along with a well-defined plan of action in line with software testing.  https://dev.to/woodjessica/implementing-functional-regression-testing-in-agile-devops-m0d

Functional testing is a form of testing and is a quality assurance process that helps to validate the system or components against various functional specifications and requirements outlined.  Functional testing is a type of black-box testing as the source code of the application is not considered during the testing process.

It is a type of software testing where the software system is validated against the functional specifications/requirements. It ensures that all the functionalities of the application are working as expected. Functional unit test cases will be created by the development team with respect to business requirements/users and functionality requirements are specified by testers based on the user perspective. https://www.testingxperts.com/blog/functional-testing Thanks!
