Once programming is complete, it is common to perform Special Data step-by-step testing in the following order to check whether the system meets the requirements definition and whether it behaves as expected. 1. Unit test 2. Integration test 3. Comprehensive test 4. Operational test Related article: An engineer explains the purpose and function of the test Step 4. Maintenance/Operation In order to continue using a released app, it is necessary to monitor it for any defects.

Regular updates are essential to keep released apps in good condition. Related article: How much does “website maintenance” cost?
