Drawbacks of Manual Testing

• Manual Testing requires more time or more resources (Human resources and Environmental Resources), some times both.
• Performance testing is impractical in manual testing(Organizing thousands of machines and human users is not possible).
• Less Accuracy (Human Users may make mistakes)
• Executing same tests again and again is time taking process as well as Tedious.
• Verifying GUI Objects Size differences and Color combinations are not easy in Manual Testing.
• Not Suitable for Large scale projects and time bounded projects.
• Batch Testing is not possible, for each and every test execution Human user interaction is mandatory.
• Manual Test Case scope is very limited (Human user can concentrate on one or two verification points only), if it is Automated test, scope is unlimited (Tool is software It can concentrate on multiple verification points at a time).
• Comparing large amount of data is impractical (If we want compare Thousands of Records, it is not possible, but Test Tool can compare thousands of records).
• Checking relevance of search of operation is difficult
• Processing change requests during software maintenance takes more time.
