FactoryBot.register_strategy
The FactoryBot.register_strategy
method is how to add a build
strategy.
It takes two mandatory arguments: name and class. The name is a Symbol, and
registering it exposes a method under FactoryBot::Syntax::Methods
.
The class must define the methods association
and result
.
The association
method takes an instance of FactoryRunner
. You can #run
this runner, passing a strategy name (it defaults to the current one) and an
optional block. The block is called after the association is built, and is
passed the object that was built.
The result
method takes the object that was built for this factory (using
initalize_with
), and returns the result of this factory for this build
strategy.
