12.1 INTRODUCTION
This chapter describes the kinds of test execution results you might want to collect,
the ways you might want to consider analyzing these results, and the interpretations
you may place on your analysis outcome.
You are almost fi nished with your testing tasks. You have completed your test
planning as described in Chapters 4 and 5. You have set up a testing environment as
described in Chapter 10. With or without automated testing tools described in Chapter
11, you have started executing your testing scenarios designed in Chapters 6-9. With
or without test management tools described in Chapter 11, you have started collecting

12.2 TEST CASES ATTEMPTED VERSUS
SUCCESSFUL
The fi rst step in discussing test execution results is to expect that you have done a

functions or business activities or structural components or performance aspects of
your application from your test planning, then your test coverage will be inadequate.
No amount of test execution of your planned coverage will give you test results
for the “un”-covered testing. The extent of “un”-covered testing usually becomes
