Write tests

Problem/Motivation

It is not feasible to test every functionality manually after making changes to module. Hence, write automated tests.

Proposed resolution

Tests should cover the following cases:

• Verify cart blocks
• Verify whether default module configuations are working
• Verify the previous behavior in "/cart" page
• Verify whether changes in module configurations are reflectiing
• Verify add/update/remove products from cart as authenticated user (without any special permissions, just authenticated)
• Verify add/update/remove products from cart as anonymous user (not required)
• Verify effect of cart with 0/less-than-zero/greater-than-zero update count
• Integration with Commerce coupon 2 #2499725: Negative order total with coupon
• Respect required fields on add to cart form #2362869: Respect required fields on add to cart form
• Show correct selling price (discounted price if applicable) #2338129: Compatibility with Commerce Discount

Remaining tasks

Write tests and setup Travis CI integration.
