Example: automattic car lock
- let's model automattic car lock
- when car is parked
- and engine is not running
- ...
- after 2 minutes
- car should be locked
- think about all the "and ..." needs
- 2 mins to write all of them down
- lets see phpspec in action
Get composer
https://getcomposer.org/download/
Create composer.json
{
"autoload": {
"psr-0": {
"": "src/"
}
},
"require-dev": {
"phpspec/phpspec": "~2.0"
},
"config": {
"bin-dir": "bin"
}
}
Create composer.json
php composer.phar installLets code
Example: Savings
- we are a cool banking startup
- on each bank transaction
-
round up (€7.22 to €8)
-
send difference (€0.78) to savings account
-
-
dont think about boring security stuff, we have their CTO's ear
-
model it in teams
-
present your model
Thank you all
