ERP implementation projects require different types of testing during the testing phase of the project. Each type represents a different objective, scope, and depth of testing.
The following diagram highlights the different types of testing in a typical implementation project:

As shown in the diagram, we can categorize testing into four main categories: Feature Testing, System Integration Testing, User acceptance testing, and End to end testing (or cut-over testing).
