# My scalatest scalacheck flow

#### Introduction

- I start with generating
`simple values`

required for my`class hierarchy`

, In this phase I generate`Long`

`Double`

values. - I move forward to create
`generators`

for more complex`case classes`

. - I create
`Lists`

of these`case classes`

. - Finished modeling the
`data structures`

moving on to using them in`tests`

!

##### Generate simple class

##### Generate simple class frequencies

- Defined relative frequencies for arbitrary generated
`longs`

and for`Long.MaxValue`

in this case`20/1`

##### Generate a complex class

- We used the
`for`

comprehension and in each`iteration`

we call`Arbitrary(somegen).arbitrary`

to get an ..`arbitrary`

value we use this arbitrary value in order to`yield`

our requested`data structure`

.

##### General list of objects

Now that we know how to generate our `case class`

lets generate a `list`

of it.

we created a new `generator`

, our new generator is calling `Gen.containerOf[List, OurType]`

and passing as its `argument`

our `single case class generator`

.
