Demo Questions
Question 1
Assume that you are the Test Manager for a small banking application development project.
You have decided to adopt a risk-based testing strategy and 5 product risks (R1, R2, R3, R4, and R5) have been identified during the quality risk analysis.
The following table shows the risk level associated to these product risks (higher numbers mean higher risk):
55 test cases have been designed and implemented to cover all these 5 product risks. The coverage is described in a traceability matrix.
This is the test execution status table, after the after the first week of test execution:
About 56% of the planned test cases have been successfully executed.
Assume that no additional product risks have been identified during the first week of test execution.
Which of the following answers would you expect to best describe the residual risks associated with the identified product risks, at the end of the first week of test execution?
- Since R3 is the only risk for which all test cases have passed, the risk has been reduced by 20%
- The test execution status table indicates that the risk has been reduced by 56%
- The residual risk level can’t be determined, because it requires that all the test cases have been executed
- The test execution table doesn’t give an indication of the risk level of the open defects and the test cases that failed or are not run yet
Correct answer: D
Question 2
You are the Test Manager for a project to develop a client-server application that allows wine vendors to order custom-assorted packages of wines of several winemakers to sell special packages in their wine shops.
You decide to apply a blended risk-based and reactive testing strategy. Below the exit criteria for the system testing.
EXCR1- Each “critical” quality risk item must be covered by at least one test condition
EXCR2- Each “critical” requirement must be covered by at least one test condition
The following are the “critical” requirements of the application:
REQ-SEL-1. The application shall allow the user to order only one package at a time
REQ-SEL-2. The application shall allow the user to select between four different packages (2-bottles, 6-bottles, 12-bottles, 15-bottles)
REQ-SEL-3. The application shall allow the user to order a package containing at least 1 bottle and no more bottles than the package size. No error messages shall be displayed if the user selects a valid number of bottles (at least 1 bottle and no more than the package size)
REQ-SEL-4. The application shall display an error message “Invalid number of bottles” if an invalid number of bottles is selected by the user (zero bottles or a number higher than the package size)
REQ-PAY-1. The application shall allow the user to pay with the three accepted credit cards (Visa, MasterCard, American Express)
REQ-PAY-2. The application shall display an error message “Invalid credit card” if invalid credit card data are given by the user
The following is the unique “critical” quality risk item that has been identified:
CR-RSK-1. The GUI of the application might accept non-integer values for the input field designed to get the number of bottles from the user
Test analysis for system testing has just begun and the following test conditions have been identified.
TC-SEL-2. Test the selection of the package sizes
TC-SEL-4. Test wrong numbers of bottles for an order
TC-CR-RSK-1. Test the accepted values from the input field designed to get the number of bottles from the user
Assume that you have used traceability to determine the logical test cases that cover all the requirements and the single risk item identified in that scenario.
Which of the following is a positive logical test that is complete and correct, and covers the REQ-SEL-4 requirement?
- Select a 6-bottles package, then try to insert 5 bottles; verify that no error messages are displayed
- Select a 6-bottles package, then try to insert 7 bottles; verify that no error messages are displayed
- Select a 6-bottles package, then try to insert 7 bottles; verify that the "Invalid number of bottles" message is displayed
- Select a 6-bottles package, then try to insert 7 bottles
Correct answer: C
Question 3
The following are the requirements identified as “critical”:
REQ-SEL-001. The user shall be able to combine all the three products with all the four durations to define an item to purchase
REQ-SEL-002. The user shall be able to add a maximum of six different items to the shopping cart
REQ-PUR-001. The user shall be able to purchase all the items in the shopping cart using a credit voucher
REQ-PUR-002. The user shall be able to purchase all the items in the shopping cart using the available credit already charged on the smartcard
REQ-PUR-003. The user shall be able to purchase all the items in the shopping cart using all the accepted credit cards (Visa, MasterCard and Great Wall Card)
REG-LOGO-001. The user shall be able to logout (by clicking the logout button) from both the “select” and “purchase” pages going back to the “browse” page (anonymous navigation)
Moreover the following quality risk item has been identified as “critical”:
QR-P1. The web customer portal might not be able to provide the expected response time (less than 10 sec) for the purchase transactions under a load of up-to 1000 concurrent users
Test analysis for system testing has just begun and the following test conditions have been identified.
TC-SEL-01. Test the combinations of products and durations to define an item to purchase
TC-SEL-02. Test the maximum number of items, which can be added to the shopping cart
TC-PUR-01. Test the purchase of an item
TC-PUR-02. Test the purchase of an item with the credit charged on the smartcard
What is the MINIMUM number of test conditions that must be added to fulfill both the EXCR1 and EXCR2 exit criteria?
- 1
- 2
- 3
- 4
Correct answer: C
Question 4
You are the Test Manager for a project to develop a web customer portal of a Pay-TV company that allows customers (with a smartcard and a set-top box) to purchase digital contents.
In the "select" page the system displays a dialogue where the customer can select the items (digital contents) he/she is interested in. In this page he/she can add one or more items to a shopping cart. An item consists of a product and a duration.
There are three types of products: Movie, sport and premium (movie and sport).
There are four possible durations: 1 months, 2 months, winter (from the beginning of January to end of March) and summer (from the beginning of July to end of September).
All the combinations of products and durations are allowed to define an item. Thus there are twelve possible items. A maximum of six different items can be added to the shopping cart at a time.
When the customer decides to check out he/she goes to the "purchase" page where he/she can pay the total amount of the shopping cart in three different ways:
- using a credit voucher
- using a credit already charged on the smartcard
- using a credit card (accepted credit cards are. Visa, MasterCard and Great Wall Card)
The customer can logout from both the “select” and “purchase” pages. In this case no purchase is made.
You decide to apply a blended risk-based and reactive testing strategy and the following is a subset of the exit criteria for system testing:
EXCR1- Each “critical” quality risk item must be covered by at least one test condition
EXCR2- Each “critical” requirement must be covered by at least one test condition
You are following a risk-based testing strategy. The test execution time is very limited. Assume that all the product risk items require more or less the same level of test effort.
Which of the following answers describes the best execution schedule in this scenario?
- 1- Test the acceptance of transactions coming from the IVR channel2- Test the correct charge of the Smart Card with the required contents3- Test the correct pre-activation of the Smart Card4- Test the correct activation of the Smart Card
- 1- Test the correct pre-activation of the Smart Card2- Test the correct charge of the Smart Card with the required contents3- Test the correct activation of the Smart Card4- Test the acceptance of transactions coming from the IVR channel
- 1- Test the correct activation of the Smart Card2- Test the correct pre-activation of the Smart Card3- Test the correct charge of the Smart Card with the required contents4- Test the acceptance of transactions coming from the IVR channel
- 1- Test the correct pre-activation of the Smart Card 2- Test the correct activation of the Smart Card3- Test the correct charge of the Smart Card with the required contents4- Test the acceptance of transactions coming from the IVR channel
Correct answer: D
Question 5
Assume you are working on a CAS (Conditional Access System) for Pay-TV that allows the access, selection and transfer of services and media to authorized users. Authorized users can choose their services through different channels: Web Customer Portal, IVR (Interactive Voice Response), Call Centre and SMS. The system uses a Smart Card to receive and decrypt the broadcasted encrypted control words which allow decrypting pay-per-view TV. Every authorized user must have a Smart Card and a Set-Top Box to view the contents.
The following is an excerpt from the product risk analysis document:
Both likelihood and impact have been rated on the following scale: (1 – Very low, 2 – Low, 3 – Medium, 4 – High, 5 – Very High).
The required test environment and code have been delivered. All test cases for each identified product risk item have been written and are ready to be executed. The Database used to contain the Smart Cards is empty and so only new Smart Cards can be used during test execution.
A Smart Card can only be activated if it has been previously pre-activated. This means the post-conditions for the execution of the test cases to test the pre-activation of the Smart Card are the pre-conditions for activation of the Smart Card.
Which of the following statements represents the most effective contribution of the stakeholders to the completion of the failure mode analysis table?
- The aircraft pilot and the customer representative should contribute to assess the detection. The chief software engineer, the system architect and the expert tester should contribute to assess the priority.
- The aircraft pilot and the customer representative should contribute to assess the priority. The chief software engineer, the system architect and the expert tester should contribute to assess the detection.
- The system architect and the chief software engineer should contribute to assess the priority. The expert tester is the only one who should contribute to assess the detection.
- The aircraft pilot is the only one qualified to contribute to assess the priority and thus should be assigned this task. The customer representative should contribute to assess the detection.
Correct answer: B
Question 6
Assume that the following test cases have been executed at the end of the first week of test execution: TC-001, TC-002 and TC-007. All these tests are ‘passes’.
What is the MINIMUM number of the remaining test cases that must be successfully executed to fulfill the EX1 exit criteria?
- 4
- 5
- 6
- 7
Correct answer: A
Question 7
You can count on well-written requirements, but you can’t count on an adequate contribution of the stakeholders to the quality risk analysis. You have to mitigate the insufficient contribution of the stakeholders because the risk-based testing approach shall minimize the product risks. Your test team has one expert tester in security testing.
Which of the following test activities would you expect to be the less important in this context?
- Extract from the defect tracking system of the previous project all the security defects and failures, and classify them to support design and execution of specific tests
- Automate all functional and non-functional system tests
- Apply systematic and exploratory testing for integration and system test
- Perform exploratory testing sessions with adequate charters covering security aspects
Correct answer: B
Question 8
During the follow-up phase the following conditions are checked:
X1. The code has been completely reviewed
X2. All the identified defects have been correctly fixed and the modified code has been compiled successfully and run through all the static analyzers used by the project without warnings and errors
X3. The modified code is available under the configuration management system with a new version number for the specified CI
If these conditions are fulfilled then the review process terminates.
Which of the following characteristics of a formal review is missing in this description?
- Defined entry and exit criteria
- Checklists to be used by the reviewers
- Deliverables such as reports, evaluation sheets or other review summary sheets
- Metrics for reporting on the review effectiveness, efficiency, and progress
Correct answer: D
Question 9
Assume you are managing the system testing phase of a project.
The system test execution period is scheduled to twenty weeks.
All tests are manual tests. You are following a risk-driven test approach.
During the last staff meeting the project manager tells you new deadlines that will not allow completion of all the system tests.
Which of the following would you expect to be the best way to respond to this situation?
- Prioritize executing the tests for the highest product risks and track these risks
- Remove testers from your test team, so that they can be assigned to other projects
- Automate all remaining tests
- No action is needed, test as much as possible in the remaining time period
Correct answer: A
Question 10
In the test strategy document your organization declares:
- To adopt a V-model development lifecycle, with three formal levels of testing unit, integration and system testing
- To use a blended risk-based and regression-averse testing strategy for each level of testing
The following is an excerpt of the “approach” section for the system test plan document of a new project:
“Testing will only use manual tests. Due to the short period of time for test execution, the following activities will be performed in parallel with test execution: Test planning, test analysis and test design.
Basic metrics will be taken for test effort (i.e. person-hours), test cases executed (passed/failed), and incidents (no more metrics, such as code coverage, will be collected).”
In the system test plan, no deviations from the test strategy are described.
Based only on the given information, which of the following statements is true?
- The approach described in the system test plan document is consistent with the test strategy
- The approach described in the system test plan document is consistent with the risk-based testing strategy, but it is inconsistent with the regression testing strategy
- The approach described in the system test plan document is consistent with the regression testing strategy, but it is inconsistent with the risk-based testing strategy
- The approach described the system test plan document is inconsistent with both the risk-based and regression testing strategies
Correct answer: D
