TDD
Create things out of thin air
Put life into the inanimate
Bend reality to our will

Thoughts and prayers
Do thy bidding
BUGS
Are thoughts gone wrong
TDD
- Validate thoughts before they get into the system
- Validate translated thoughts in action
TDD
is time consuming
TDD
takes fear out of refactoring
TDD
enable tracking impact of your changes
TDD
validates how your new thoughts impact what you used to think
TDD
freed us up for
- Deliver twice as much
- Dev Ops
- Creating and maintaining an admin panel
- Contributing to other teams
TDD
is about Tests
DD
is more important than
T
Validate your thoughts BEFORE they enter the system
Tests written after the fact are practically handicapped
TDD
means no bugs
TDD
is your last line of defense
BDD
Protect yourself from your PO
Adopt
TDD
guide developers toward best practices
Focus on what before how
Single Responsibility Principal is a must for testable code
Appreciation for DI and other design patterns
TDD
is a culture shift
Brace yourself for
- Resistance
- A learning curve
- Lots of doing it wrong (if there is noone to guide)
Coverage reports are big fat liars
Things I wish we did
I wish we did
Mutation Testing
- Because coverage Reports are big fat liars
- Check how strong your tests actually are
- Identify dead code/tests
I wish we
BDD
- Catch the thoughts before they enter the system
- Test your entire infrastructure
- SolidSoftware = TDD + BDD
- Make that acceptance criteria executable
early on
Adopted
A bit AHEAD OF TDD
USE A
programming language
- Dynamically typed languages cause more trouble than they are worth
- Static Languages are expressive/elegant enough
- Linting is not the answer
- Ridiculous amount of tests can just vanish with a decent type system
proper
CTRL + S
- No more fights for code formatting style
- No more noise in Code Reviews
