-   * Check that the tax rate isn't reapplied to line item's unit price and total amount
+   * CRM-21656: Test the submit function of the membership form if Sales Tax is enabled.
+   * This test simulates what happens when one hits Edit on a Contribution that has both LineItems and Sales Tax components
+   * Without making any Edits -> check that the LineItem data remain the same
+   * In addition (a data-integrity check) -> check that the LineItem data add up to the data at the Contribution level

+   * NOTE/discussion on merging in assertions that are commented out (for now):

+   * Quick summary: the following assertions are commented out for now as they currently Fail. Work is being done to figure out why the
