Staging

Questions:

• should we/when assert component has been called with proper arguments ? unit ? component ?
• component test between non in/out component ?
• downside of unit tests ?

Unit test

Make it work

• use response (or it will fail): use stub
• does not use response: use fake (cause no error)

Code nature

• Side-effect free (pure) => test state (return values) => no need for mocks
• Side -effect (impure) => test side-effect (outside calls) => need spies

Integration test: Side effect ?
