Lecture 1 - A Bug or Not a Bug -> Quick Intro -> Three Conditions Of A Bug’s Existence -> The Gist Of Testing
A bug exists only if ALL of the following three conditions are met:
1. We know the expected result
2. We know the actual result
3. We know that the actual result deviates from the expected result
BTW
My advice: Every time you see a mismatch between the actual and expected, label that situation with the word “bug.” As time goes on, you’ll develop a habit, which will gradually grow into a reflex. Please note that for the sake of this training, it doesn’t matter how futile, cheap, or temporary your expectations are – the main thing here is to gain the skill of automatic bug recognition.
Example
Here are some more bugs from real life:
1. A nice face backed up by ugly personality.
2. Parrots say the nastiest words at absolutely inappropriate times.
3. Hollywood story: reach fame and drink yourself to grave. Next ->
