Are you an agile tester?


Agile testing principles

• Collaboration

• Communication

• Transparency

• Being part of the specification

• Subjective testing techniques (e.g. exploratory testing)

• Integration to the delivery team

Being part of the specification


Specify with Given/When/Then

Collaboration


Did you feel like an equal member?

Yes… equally unhappy

Bug Hunting → Bug Prevention


Requirements vs. Tests

As formality increases, tests and requirements become indistinguishable. At the limit, tests and requirements are equivalent.

Equivalence Hypothesis (Martin, Melnik)

Agile testers duringpreparation…


Develop test strategy


Decide on the automation target

…and manage the consequences


Agile testers during preparation…

• Develop test strategy

• Ensure / verify feasibility of the strategy• (tools, infrastructure, skills)


Agile testers duringplanning…


Finding acceptance criteria

“Imagine this story is

already implemented:

How would you verify

it?”

“I would try to put a book

into the shopping cart …”

“I would try to remove a

book from the shopping

cart…”

“I’d check whether the shopping

cart is empty, when I enter the

shop …”

Shopping cart should be

empty when entering the

shop

What happens, if I search for

“Explore Specification”?

Can I search for single

characters, e.g. “e”?

Is the number of search results

limited, or paged?

Is the search also performed in the

sub-title of a book?


Agile testers during planning…

• Help structuring ideas to acceptance criteria

• Find key examples

• Helps deciding if a check should be automated

• Consider edge cases

• Define exploratory testing goals


Agile testers duringSprint…

Establish build status indicators



Agile testers during Sprint…

• Formulate business readable tests (e.g. Gherkin), • right before implementing them

• Support team with continuous verification of stories

• Build new tests from existing building blocks

• Perform AC check

• Help preparing for the demo

• Keep control of default/baseline data

• Ensure that the feedback from the tests is shown to everyone


Agile testers after Sprint…

• Share experience

• Help others to learn about agile testing
