Not worth a re-roll, but these quote sequences are brain-melting.
Easier would have been to double-quote the second argument of
test_expect_success() and then do either:

    test_expect_success 'sanitize-config keeps credential.helper' "
        git -c [...] submodule--helper sanitize-config >actual &&
        echo \'credential.helper=helper\' >expect &&
        test_cmp expect actual
    "

or:

    test_expect_success 'sanitize-config keeps credential.helper' "
        git -c [...] submodule--helper sanitize-config >actual &&
        cat >expect <<-\EOF &&
        'credential.helper=helper'
        EOF
        test_cmp expect actual
    "
