I remember following Six Essentials / Parables for Testers as described in a wonderful book on Software Testing.
SE –1: Success of any testing effort is determined by the quality of the testing process.
SE –2: Deploy early life cycle testing techniques if you want to prevent migration of defects.
SE –3: For improving a testing process, a real person must own its responsibility.
SE –4: Testing is a professional discipline and requires trained & skilled personnel.
SE –5: Use the software testing tools to improve the testing process & save time.
SE –6: Positive team attitude of creative destruction must be cultivated.
The above-mentioned essentials had been described in a wonderful book – Titled:
"Software Testing in the Real World" by Edward Kit
These essentials fascinated me & I am sharing with my readers.
