In this chapter, you were introduced to the basics of quality assurance. You first learned what quality really means in application development, and the six core concepts that constitute it.
You then learned how many of those concepts can be tested in the real world to determine and measure quality on any given project, and how best to record the results of those tests.
Finally, you were introduced to Mantis, a powerful bug tracking and fault management tool. You learned how to install and configure it, as well as how to use it from day to day for your own projects.
By now, you should have a quality product, free from defects. In the next chapter, you'll learn how to devise an effective deployment strategy for getting that product from your development and staging servers onto a live environment.
