expect { some_method }.to raise_error
expect { some_method }.to raise_error(SomeError)
expect { some_method }.to raise_error("oops")
expect { some_method }.to raise_error(/oops/)
expect { some_method }.to raise_error(SomeError, "oops")
expect { some_method }.to raise_error(SomeError, /oops/)
expect { some_method }.to raise_error(...){|e| expect(e.data).to eq "oops" }

# Rspec also offers to_not:
expect { some_method }.to_not raise_error
...

참고 : raise_error및 raise_exception교환 할 수있다.

RSpec 1

lambda { some_method }.should raise_error
lambda { some_method }.should raise_error(SomeError)
lambda { some_method }.should raise_error(SomeError, "oops")
lambda { some_method }.should raise_error(SomeError, /oops/)
lambda { some_method }.should raise_error(...){|e| e.data.should == "oops" }

# Rspec also offers should_not:
lambda { some_method }.should_not raise_error
...

참고 : raise_error의 별칭입니다 raise_exception.

답변

   expect { some_method }.to raise_error

expect { ... }.to raise_error(ErrorClass)

expect { raise StandardError }.to raise_error # results in warning
expect { raise StandardError }.to raise_error(StandardError) # fine
