Who the fuck is this clown?

What am I going to prattle on about?

• We're going to take a whistle stop tour through a career in software development in Ireland
• How these projects were tested, both by myself and .....
• The testers I had the pleasure or fucking joy of working with

Lets start with college

• They honestly tried, there was just no context

• Exposed to unit tests
• Learned selenium

An online bank

• A fat front end in modern terms, JSF
• Spring webflow mid end and a monster mainframe out back somewhere

We were rebuilding the bank from scratch

The old version of the bank was in a heap

How did we automate tesing

• Unit tests from day one
• Into the project we included selenium tests as End-to-end tests

• No TDD
• No ATDD / BDD

How did we test manually

• After a piece of work had passed automated testing we'd hand it over to a tester
• The tester wrote test scripts (not the automated sort) 
• Any deviation from the script was a bug

• Test scripts and specifications from a Business Analyst were not necessarily related

How do I test while I'm actively developing something?

• Stage 1 : Actively trying to make it work
  • Pick a path (mostly happy) and don't change it
• Stage 2 : How well does it work
  • Try other paths

How did we communicate with our testers

We meet our first tester

L

Our system tester

L

• Mean and scary
• Sat in the office next door
• Only interacted via Bugzilla

L

• An absolute pleasure to work with
• Was able to explain in detail how the system was supposed to work

When the offices were reschuffled

L

"Can I ask you a question"

Why is co-location of developers and testers important?

Our second tester

S

Our UAT Tester

S

• Worked in a different building miles away 
• Hated the fucker
• Only interacted via Bugzilla

Didnt have one!!!

Developers look at what they've build as their code baby

It can be easy to hurt their feelings 

Greenfield event trading WS

• Jersey, Spring, Hibernate
• jUnit, jMeter and later jBehave 

• High levels of unit test coverage from day one
• We had improved on what we had learned up to that point, but our work was still exceedingly buggy

Because what we were building was wrong

• We were building off a spec that was thrown at us from another dept
• We'd complete work, only to have it kicked back
• Doing what you're told isn't always a good thing
• We hadn't yet learned to question everything

Tester 3

SG

Our BA, who was also a tester ..... sort of

SG

• Even meaner and a lot scarier than L
• Knew our business domain inside and out

New message distribution system

We were rebuilding a massive part of our infrastructure 

We got Testers

We got our hands on 4 genius testers

... and we learned to question everything

We put ATDD at the forefront of our development strategy

All work was agreed and specified in Given-When-Then format before development began

Developers weren't allowed throw cards over a wall at testers

An actual agile tester

M

Not leaving out G, MC and D

M

• M was confusing when we first met
• She asked questions about everything
• ...... figuratively everything
• M became a port of call when you wanted to know how something worked

Lets talk about a developer

J

Junior Java Developer

J

• Arrogant, could do no wrong
• "Do we really need to test this"
• "That's not automatable"
• Had to be constantly brought into line with the rest of the team
• When the environment changed, his negative behaviour resurfaced

We automated everything .....

• Unit test coverage
• Acceptance tests defined by our business
• Static analysis
• Security analysis
• Mutation Testing

Automation puts a focus on quality

• If unit test coverage fails a build, more must be written
• Criteria agreed at the outset of work must be implemented. Anything outside this criteria isnt a bug, its a change
• If sonar complains about code, theres not much room for debate
• .... no one likes security analysers, as necessary as they may be
• I've never seen a developer win an argument against a mutation test

Developers weren't trying to make it

Testers weren't trying to break it

Everyone was in the same quality focused boat

M

"We have a bug in UAT!!!!"

... and then we tried to do front end work

We had to learn how to test again

We wrote our own testing framework

How can I help developers to be better testers?

• Get em early
• Automate everything, make a system the bad guy
• Much of it comes down to team culture
• Its difficult to hate a tester you have a personal relationship with
• You cant expect developers to develop features they haven't been asked to
• The process has to make developers accountable
