Pattern: Inconsistent style when matching nil

Issue: -

Description

Ensures a consistent style is used when matching nil.

You can either use the more specific be_nil matcher, or the more generic be matcher with a nil argument.

This rule can be configured using the EnforcedStyle option

Examples

EnforcedStyle: be_nil (default)

# bad
expect(foo).to be(nil)

# good
expect(foo).to be_nil

EnforcedStyle: be

# bad
expect(foo).to be_nil

# good
expect(foo).to be(nil)

Configurable attributes

Name	Default value	Configurable values
EnforcedStyle	be_nil	be, be_nil
