The Importance of Testing

• Recognizing Faults : Errors can be in unit level or system level. After going through testing the application will be free of errors.
• Enhancing Product Standards : With proper testing an application can be bug-free. This helps to build up ideal software for the end-users.
• Evaluating Credibility : If the software application has gone through all testing types (like unit testing, regression testing, smoke testing, etc.), the application will be a reliable one.
