Stub
To stub your containers call #stub method:
container = Dry::Container.new
container.register(:redis) { "Redis instance" }
container[:redis] # => "Redis instance"
require 'dry/container/stub'
# before stub you need to enable stubs for specific container
container.enable_stubs!
container.stub(:redis, "Stubbed redis instance")
container[:redis] # => "Stubbed redis instance"
Also, you can unstub container:
container = Dry::Container.new
container.register(:redis) { "Redis instance" }
container[:redis] # => "Redis instance"
require 'dry/container/stub'
container.enable_stubs!
container.stub(:redis, "Stubbed redis instance")
container[:redis] # => "Stubbed redis instance"
container.unstub(:redis) # => "Redis instance"
To clear all stubs at once, call #unstub without any arguments:
container = Dry::Container.new
container.register(:redis) { "Redis instance" }
container.register(:db) { "DB instance" }
require 'dry/container/stub'
container.enable_stubs!
container.stub(:redis, "Stubbed redis instance")
container.stub(:db, "Stubbed DB instance")
container.unstub # This will unstub all previously stubbed keys
container[:redis] # => "Redis instance"
container[:db] # => "Redis instance"
