Make user storieswrite out all the different actions users can andcan’t do

Write out Acceptance testsUsing Rspec/Steak

Write out the ﬁrst scenarioDo this before you actually create the feature

Run the tests!And it fails! But we where expecting that...

Go ahead!Create thatfeature!Yeah boi, its hammertime!

Run it again and... no failures!Yippy!

That wasn’ttoo hardLets step it up

Write out the second scenario
