ruby on rails - Testing mailer 'from' header using rspec -

i working on ruby on rails project, trying test 'from' header field test case fails.

here setting in mailer action

def some_actoin   mail(to: xyz@example.com,          from: '"example" <service@example.com>',          subject: "test subject")   end end

and in rspec test case,

mail.from.should == '"example" <service@example.com>'

my test case failing following error

expected: '"example" <service@example.com>' got: [service@example.com] (using ==)

is wrong way test from-header title from-header email address?

appreciates help!

the mail.from contains email address. you'll want test display name too.

mail.from.should eq(['service@example.com']) mail[:from].display_names.should eq(['example'])
