Which of the following is an improvement to the test process that you might suggest? Assume you are a test manager in charge of integration testing, system testing, and acceptance testing for a bank. You are working on a project to upgrade an existing automated teller machine system to allow customers to obtain cash advances from supported credit cards. The system should allow cash advances from $20 to $500, inclusively, for all supported credit cards. The supported credit cards are American Express, Visa, Japan Credit Bank, Eurocard, and Mastercard.\nÂ \nDuring test execution, you find five defects, each reported by different tester, that involve the same problems with cash advances, with the only different between these reports being the credit card tested.
A. Revise all cash advance test cases to test with only one credit card. B. Review all reports filed subsequently and close any such duplicate defect reports before assignment to development. C. Change the requirements to delete support for American Express card. D. Have testers check for similar problems with other cards and report their findings in defect reports.
