2. MAINTENANCE TESTING
• Testing that is executed during this life cycle phase is called
'maintenance testing‘
• The Testing done during this enhancement, change and migration
cycle is known as maintenance testing.
• Maintainability testing is different from maintenance testing
• On receipt of the new or changed specifications, corresponding test
cases are specified or adapted
• In maintenance testing, tester should consider 2 parts:
1. Any changes made in software should be tested thoroughly
2. The changes made in software does not affect the existing
functionality of the software, so regression testing is also done.For which
impact analysis is done
