CTAL-TTA Exam Dumps : Certified Tester Advanced Level Technical Test Analyst

Consider the following specification:

If you are flying with an economy ticket, there is a possibility that you may get upgraded to business class, especially if you hold a gold card in the airline’s frequent flier program. If you don’t hold a gold card, there is a possibility that you will get ‘bumped’ off the flight if it is full when you check in late.

This is shown in the control flow graph below. Note that each box (i.e., statement, decision) has been numbered.

Three tests have been run:

Test 1: Gold card holder who gets upgraded to business class

Test 2: Non-gold card holder who stays in economy

Test 3: A person who is bumped from the flight

What is the level of decision coverage achieved by these three tests?

You are working on a complex systems integration project that will soon be deployed to the production environment. This system is replacing a system that was popular with the users and had no outstanding non-functional issues. There are multiple components that interact and these have been developed by various development and testing groups including some outsourced groups. You will be leading the performance testing effort. Although you would prefer to have a dedicated test system for this effort, you will have to use the production system. You can do this testing at a low usage time, but there will be some users on the system and you will be using real data for the tests. You are now planning your performance testing. Unfortunately, there are no requirements for the performance requirements of the system. How do you determine the acceptable performance levels for the various operational profiles?

BestFor Incorporated is a rapidly growing online financial services company that offers guidance to its customers on a range of financial products. Its first website, BestForMortgages, was launched two years ago, shortly followed by BestForPensions. The popularity of both sites has driven the company to expand its offerings into other sectors and a third website, BestForFood, has recently been released.

The first two websites have proven to be functionally robust but suffered from performance issues due to:

Underestimation of concurrent user access at peak times in its original operational profiles

Data volumes rapidly growing beyond expectations on a single database shared by both sites.

All three websites share the same web server.

The BestForFood system has been running live for several months, however the following significant non-functional defects have been recorded:

A) The layout and navigation of the BestForFood website was not considered by the users as consistent with BestForPensions and BestForMortgages

B) Soon after delivering the BestForFood system the performance of both BestForPensions and BestForMortgages noticeably slowed

C) The time taken to diagnose, repair and re-test production defects did not meet BestForFood service level agreements

D) BestForFood performance was adversely impacted by unexpected growth in data volumes

E) The time taken to install monthly builds into the production system exceeded agreed timescales.

Which TWO of these defects might have been prevented had portability testing and compatibility testing been employed?
