3. We’ve heard it since the dawn of “agile”…
Everyone on the team should be able to do
everything, including writing production
code

4. We need to automate
everything!
Let’s hire some SDETs!
But shouldn’t we be trying
to build quality in?

5. Reality Check…
• Many (if not most) job ads ask for
programming skills
• Managers think test automaEon is a silver
bullet
• Technical skills help testers communicate
with devs, ops, others

6. Our take
• TesEng skills such as exploratory tesEng are a must
• Competencies trump roles
• The whole team must take responsibility for quality
• TesEng starts at the beginning
• Know what you need to add value
• There is no room for zombie testers!

9. Testers need
Technical Awareness !!
Agile teams already have coders, but…

10. This means learning…
• TesEng framework your team selects
• and the DSL (domain specific language)
• Common language with programmers
• Common language with customers
• Code to read & understand
• Code to write? – can’t hurt, but not
absolutely required
• Domain knowledge

11. Understand Programming
Concepts
Common
vocabulary

12. IDEs (integrated development environment)
If you use same
tools as
teammates…
…they can more
easily help you

13. Feature

14. Frameworks / languages /
terminology
Example of BDD format
Given the user has no exisEng account
When she requests to create a new account
And she enters a valid user name and valid password
(rules defined)
Then the informaEon is saved upon submifng.

15. Testing
Skills

16. Workflows, Journeys

17. Thinking
Skills

18. Examples of thinking skills
• CollaboraEng,
communicaEng
• EliciEng examples
• Asking quesEons
• Gefng/delivering info:
“Show me”

19. SEcker by Brian Marick

20. 1. Find a pair
2. One person faces away from the screen
3. The other person will have 2 -3 minutes to
describe the picture I show next
4. When I say stop, turn around and discuss any
differences in what was described.

22. Testers add unique value
• Delivery teams already have coders
• But may not have tesEng skills such as:
• Exploratory tesEng
• SpecialEes such as security, performance, UX
tesEng
• EliciEng examples from customers, turning into
tests that guide coding

23. So, do we need to be coders?
• Dev teams already have
coders!
• Technical awareness is a must
• Thinking skills enable our
contribuEons
• Specialized tesEng skills add
huge value

24. Where to get the skills?
Experiment!
• Study group, book club
• Community of PracEce
• Online resources
• What fits your learning
style?
• Find the wonder!

25. There’s not one right way
Find ways testers can add
value to your team
And then …. keep learning
