Background

Bug, Defect, Error

James Bach and Michael Bolton in 2009

No right or wrong… it’s an opinion

Arguable advantages to considering it

Reasons for the distinction

“Anyone can test”

“Automation will replace testing jobs”

“How can testing add value?”

There were parts of my job I didn’t like… and I never understood why

The distinction

Checking has an output bit(“Yes or No” / “Pass or Fail”)

Testing often has anopen-ended result

The distinction

Checking is confirming an expectation

Testing is, sometimes, not knowing what to expect

The distinction

Checking is about if something works

Testing is about defining what "works" means

The distinction

Checking is looking at a system from the eyes of requirements

Testing is also looking at a system from the eyes of a user

The distinction

Checking, more often than not, needs requirements

Testing sometimes questions the requirements and often goes beyond the requirements

The distinction

Checking is, or can be, machine-decidable

Testing requires judgement

The distinction

Checking is arguably simple

Testing not so much

If you realize you are a (non-automation) Checker, let this talk be a wake up call

If your company focuses mostly, or solely, on Automated Checks, know there is probably more that can be done

Things to (re)consider

If you are a recruiter, try to gauge if the company you are working with needs a Checker or a Tester

A few tips on how to cross theChecker to Tester line?

Get philosophical

Get technical

Ask questions - Experiment

Mind your feelings
