Hello,
I am a professional QA and I can test 3 modules with automation test cases.
Your questions answers are below:
1. How eBay's auction works? : At first seller (Who wants to auction any product) creates a price value for his product. Then, buyers are bid on this product to buy this. The seller sold the product for which the buyer gives the maximum bid price. More important is eBay bid means a contract.
The key characteristics of an auction are End-time/time remaining, current bid, Rate of Bidding, Shipping costs, Number of bidders, Shipping options and Shipping insurance,
2. When you add a Buy It Now option to auction-style listings, buyers can either purchase your item right away at the Buy It Now price or place a bid. ... When someone bids, the Buy It Now option usually disappears; however, in the case of reserve price listings, the Buy It Now option remains until the reserve price is met.
3. Testing process: Firstly I test these three modules' functionality. Then UI and security, performance. After I am satisfied with this testing, I will create test cases by selenium to check these modules automatically.
Regards,
Kawsher
