Demo Questions

Question 1
Which of the following statements describing the consequences of specifying test conditions at a detailed level is NOT true?
  1. In an environment where the test basis is continuously changing, it is recommended to specify test conditions at a detailed level in order to achieve a better maintainability
  2. The specification of test conditions at a detailed level can be effective when no formal requirements or other development work products are available
  3. The specification of test conditions at a detailed level can require the implementation of an adequate level of formality across the team
  4. For system testing, the specification of test conditions at a detailed level, carried out early in the project as soon as the test basis is established, can contribute to defect prevention
Correct answer: A
Question 2
Assume you are the Test Manager for a new software release of an e-commerce application. 
The server farm consists of six servers providing different capabilities. Each capability is provided through a set of web services. 
The requirements specification document contains several SLAs (Service Level Agreements) like the following:
SLA-001: 99.5 percent of all transactions shall have a response time less than five seconds under a load of up-to 5000 concurrent users
The main objective is to assure that all the SLAs specified in the requirements specification document will be met before system release. You decide to apply a risk-based testing strategy and an early risk analysis confirms that performance is high risk. You can count on a well-written requirements specification and on a model of the system behavior under various load levels produced by the system architect. 
Which of the following test activities would you expect to be the less important ones to achieve the test objectives in this scenario?
  1. Perform unit performance testing for each single web service
  2. Monitor the SLAs after the system has been released into the production environment
  3. Perform system performance testing, consisting of several performance testing sessions, to verify if all the SLAs have been met
  4. Perform static performance testing by reviewing the architectural model of the system under various load levels
Correct answer: B
Question 3
Consider an information system of a Pay-Tv company based on a SOA architecture. 
The integrated system currently consists of three core systems:
  • a CRM (Customer Relationship Management) system 
  • a BRM (Billing and Revenue Management) system 
  • a CAS (Conditional Access System) system all of them communicating with SOA Middleware. 
You have been asked to manage the testing activities for the integration of two additional off-the-shelf systems from two different vendors: a SMS (Short Message Service) server and an IVR (Interactive Voice Response) system.
Assume that there is a high likelihood that the two off-the-shelf systems will be low-quality and that you have a clear proof that the testing performed by the two vendors on their systems has been unsystematic and unprofessional. This obviously leads to higher quality risk for the overall integrated system. 
You are the Test Manager of this project. Your main goal is to plan for testing activities to mitigate this risk. 
Which of the following answers best describes the test activities (assuming it is possible to perform all of them) you should plan for?
  1. You should plan for an informal and minimal acceptance test of the two off-the-shelf systems and then a single end-to-end test of the overall integrated system
  2. You should directly plan for a single end-to-end test focused on end-to-end tests of the overall integrated system without an acceptance test of the two off-the-shelf systems
  3. You should plan for two levels: a system integration test and an end-to-end test of the overall integrated system
  4. You should plan for adequate re-testing of both the systems followed by a system integration test and an end-to-end test of the overall integrated system
Correct answer: D
