1. Prologue

2. Goal of testing (???) What do our customers want from the system?
Will it deliver what they want when thy use it?
Our goal must be their delight and satisfaction. We aim for quality but quality is not an abstract ideal

3. Quality Assurance
Monitors the software and the development processes that produce it
Ensures all compliance with established standards and procedures for the software and the software process
Ensures that inadequancies in the product, the process or the standards are brought to management’s attention

4. The Six essentials of S/W testing
The quality of the test process determines the success of the test effort
Prevent defect migration by using early life cycle testing techniques
The time for s/w testing tools is now
A real person must take responbility for improving the testing process
Testing is a professional discipline requiring trained, skilled people
Cultivate a positive team attitude of creative destruction.

6. Common Distribution of errors

7. Definitions of Testing (IEEE/ANSI)
The process of operating a system or component under specified conditions, observing or recording the results, and making an evaluation of some aspect of the system or component
The process of analyzing a software item to detect the difference between existing and required conditions (bugs) and to evaluate the features of the software items.

8. Good testers have a testing attitude
Testers hunt errors
Testers are destructive but creatively so
Tester pursue errors, not people
Testers add value

9. How testers Do IT By examining the internal structure and design
By examining the functional user interface
By examining design objectives
By examining the users requirements
By executing code
