Difference between System, Integration and E2E test

Integration Testing 

Integration Testing is a type of software testing where two or more modules of an application are logically grouped together and tested as a whole. The focus of this type of testing is to find the defect on interface, communication, and data flow among modules. Top-down or Bottom-up approach is used while integrating modules into the whole system.

 End to End Testing

It involves testing a complete application environment in a situation that mimics real-world use, such as interacting with a database, using network communications, or interacting with other hardware, applications, or systems if appropriate.

What are the benefits of using Scrum?

  Scrum in Agile  is a process that allows software development teams to focus on delivering business values in shortest time by rapidly and repeatedly inspecting actual working software. It focuses on accountability, teamwork and iterative progress towards well-defined goals. Scrum Framework usually deals with fact that requirements are likely to change or mostly not known at the beginning of project. Scrum Scrum is one of the implementations of agile methodology. In which incremental builds are delivered to the customer in every two to three weeks’ time. Scrum is ideally used in the project where the requirement is rapidly changing.
