Hi @symarys, looks like you modified test case 6? We have to keep to the official Tax Cloud test specifications, as per https://github.com/spree-contrib/spree_tax_cloud/blob/master/TaxCloudImplementationVerificationGuide.pdf. The only exception would be if Tax Cloud themselves have updated their guide, in which case we should include the latest Verification Guide in the repository as well as changing the tests.

@brchristian Thank you for the tip! It seems that the specifications changed, but at this point I cannot prove it - for the time being I reverted that commit.
