Class: FactoryBurgers::SequenceInjector

Inherits:: BasicObject

Defined in:: lib/factory_burgers/sequence_injector.rb

Overview

A SequenceInjector is a probe that can be used to hijcak a FactoryBot sequence. It injects a specific replacement value in place of the sequence argument, or any usage of that argument.

For an injector with a replacement value “foo”:

A sequence defined with a block “{ |ii| “thing-#ii ”}‘
```
will evaluate to "thing-foo".
```
A sequence defined with a block “{ |ii| “thing-#iiii.daysii.days.from_onwii.days.from_onw.month ”}‘
```
will also evaluate to "thing-foo".
```

This allows us to generate wildcard, such as for SQL

SequenceInjector.new("%")

or Regex

SequenceInjector.new(".")

Instance Method Summary collapse

#initialize(replacement_value) ⇒ SequenceInjector constructor

A new instance of SequenceInjector.
#method_missing(_name, *_args) ⇒ Object

We explicitly want to swallow and do nothing on method_missing; We want to chain all method calls until we get to to_s.
#to_s ⇒ Object

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(_name, *_args) ⇒ `Object`

We explicitly want to swallow and do nothing on method_missing; We want to chain all method calls until we get to to_s
