	Bucket: aws.String(bucket),

prime a mock call to return an error and test for it

	Context("simulate an error retrieving data from S3", func() {
	var testCall *gomock.Call
	BeforeEach(func() {
	testCall = mockFetcher.EXPECT().GetObject(gomock.Any()).Return(nil, fmt.Errorf("AWS error")).AnyTimes()
	})
	It("and fails", func() {
	_, err := ReadPersonFromS3(mockFetcher)
	Expect(err).To(HaveOccurred())
	testCall.Times(1)
	})
