Based on the historical data of 5 past and similar projects, you have calculated these average numbers of defects detected in system testing:
-for each 10000 LOC (lines of code), 200 defects
-for each person-month of development team effort, 49 defects
You want to use this information to perform estimation for a new project.
The project manager tells you that he/she has estimated 20000 new LOC for this new project.
Four developers work for four months on this project before system testing.
During system testing, 797 defects are discovered.
Assume that the system test of this new project is using the same amount of work as spent in the past projects.
Based on this information only, which of the following statement is certainly true about this project?
Number of correct responses: 1

• A. The number of defects found during the system test phase on the new project is approximately proportional to the development team effort
• B. 40000 LOC have been delivered to system testing (against the 20000 LOC planned by the project manager)
• C. More LOC than planned have been delivered to system testing with a higher defect density than the past projects
• D. The code for the new project contains a higher defect density than the code of the past projects

Assume you are the Test Manager in charge of independent testing for avionics applications.
You are in charge of testing for a project to implement three different CSCI (Computer Software Configuration Item):
-a BOOT-X CSCI that must be certified at level B of the DO-178B standard
-a DIAG-X CSCI that must be certified at level C of the DO-178B standard
-a DRIV-X CSCI that must be certified at level A of the DO-178B standard
These are three different software modules written in C language to run on a specific hardware platform.
You have been asked to select a single code coverage tool to perform the mandatory code coverage measurements, in order to meet the structural coverage criteria prescribed by the DO-178B standard. This tool must be qualified as a verification tool under DO-178B.
Since there are significant budget constraints to purchase this tool, you are evaluating an open-source tool that is able to provide different types of code coverage. This tool meets perfectly your technical needs in terms of the programming language and the specific hardware platform (it supports also the specific C-compiler).
The source code of the tool is available.
Your team could easily customize the tool to meet the project needs. This tool is not qualified as a verification tool under the DO-178B.
Which of the following are the three main concerns related to that open-source tool selection?
Number of correct responses: 3
(2 credits out of 3 credits correct, 1 credit point)

• A. Is the licensing scheme of the tool compatible with the confidentiality needs of the avionics company?
• B. Does the tool require a system with more than 4GB of RAM memory?
• C. Does the tool have a good general usability?
• D. What are the costs to qualify the tool as a verification tool under the DO-178B?
• E. Does the tool support all the types of code coverage required from the three levels A, B, C of the DO-178B standard?
• F. Is the installation procedure of the tool easy?

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
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, is correct, and covers the REG-LOGO-001 requirement?
Number of correct responses: 1

• A. On the purchase page ("purchase state"), click the logout button; verify that the browse page ("browse state") is displayed
• B. On the browse page ("browse state"), click the logout button
• C. On the purchase page ("purchase state"), click the logout button; verify that the "Impossible to logout - complete or cancel the current transaction" message is displayed
• D. On the select page ("select state"), click the logout button

You are the Test Manager on a project following an iterative life-cycle model. The project should consist of nine iterations of one month duration each. It is planned to develop the most important features to have a stable core of the application in the first three iterations and to add the additional features in the last six iterations.
At the beginning of the first iteration, only a draft version of the requirements specification document for the core features is available. Assume that during each of the first three iterations, the chosen features are fully completed and unit tested.
Which of the following statements is true in this context?
Number of correct responses: 1

• A. The system test phase should start when all the requirements are frozen
• B. You should allocate a large effort for system testing during the first three iterations
• C. You should apply the same test strategy as used in a sequential life cycle model
• D. You should allocate all the effort for the system test phase only in the last iteration

You are not confident with the assessment of the risk level and you suspect that it will be possible to find high-priority bugs in low-risk areas.
Furthermore the period for test execution is very short. Your goal is to test all the product risks in a risk-based way, while assuring that each product risk gets at least some amount of testing.

Which of the following answers describes the best test execution schedule in this scenario?
Number of correct responses: 1

• A. T1, T3, T5, T7, T9, T2, T4, T6, T8, T10
• B. T10, T8, T6, T4, T2, T9, T7, T5, T3, T1
• C. T10, T9, T8, T7, T6, T5, T4, T3, T2, T1
• D. T1, T2, T3, T4, T5, T6, T7, T8, T9, T10
