Share, care and avoid those potholes

The mental model

@gil_zilberfeld

Getting it!

Waiting for the value

Stupidest thing that works

Making decisions

@gil_zilberfeld

Versus

Greenfield vs brownfield

Feature vs bug fix

@gil_zilberfeld

From problem to solution

Starting from High-level design

ATDD as guidance

@gil_zilberfeld

Coming up with test cases

Identifying examples up front

Jump around

Incremental test-by-test

Copy and mutate

@gil_zilberfeld

Where do I stop?

Optimist vs pessimist

Best code ever

Running out of ideas

@gil_zilberfeld

Bangin’ that keyboard

@gil_zilberfeld

A rose by any other name

Convention-based

Just the specs

BDD style

@gil_zilberfeld

Two roads diverged in a wood

Easy path first

Happy path first

@gil_zilberfeld

Filling in the gaps

Test the whole functionality

Test just new functionality

Fill in the gaps without tests

@gil_zilberfeld

Algorithms

Examples

Build the framework

Hack and slash

Child tests

@gil_zilberfeld

In case of emergency

Test breaks many others

Retract and refactor

@gil_zilberfeld

Patterns are a communication tool

Once identified we can decide what to do about them
