Summary
In this chapter, you understood various testing methodologies, different approaches to system migration and cutover techniques, and the objectives of post-implementation reviews. You also learned how to conduct post-implementation reviews of systems to determine whether project deliverables, controls, and requirements have been met.
The following are some important topics covered in this chapter:
- Unit tests include tests of each separate program or module. Testing is generally conducted by the developers themselves. They are conducted as and when a program or module is ready, and it is not necessary to wait until the entire system is completed.
