RSpec/ReturnFromStub

Safe autocorrect: Yes
✅ The autocorrect a cop does is safe (equivalent) by design.

Description

Overview

Checks for consistent style of stub's return setting.

Enforces either and_return or block-style return in the cases
where the returned value is constant. Ignores dynamic returned values
are the result would be different

This cop can be configured using the EnforcedStyle option

Examples

EnforcedStyle: and_return (default)

# bad
allow(Foo).to receive(:bar) { "baz" }
expect(Foo).to receive(:bar) { "baz" }

# good
allow(Foo).to receive(:bar).and_return("baz")
expect(Foo).to receive(:bar).and_return("baz")
# also good as the returned value is dynamic
allow(Foo).to receive(:bar) { bar.baz }

EnforcedStyle: block

# bad
allow(Foo).to receive(:bar).and_return("baz")
expect(Foo).to receive(:bar).and_return("baz")

# good
allow(Foo).to receive(:bar) { "baz" }
expect(Foo).to receive(:bar) { "baz" }
# also good as the returned value is dynamic
allow(Foo).to receive(:bar).and_return(bar.baz)
