Câu 1: Which of the following statements is TRUE with respect to when the test analyst should become involved during different software development lifecycle models?

• A. In sequential V-model projects the test analyst should start test analysis concurrently with coding

• B. In sequential V-model projects the test analyst should start test analysis concurrently with requirement specification

• C. There are no differences in the moment of involvement for test analysts for the various software development lifecycles

• D. In Agile software development the test analyst should start test analysis and design concurrently with coding

Answer explanation

a) Is not correct. Test analysis must start earlier, already during requirement specification in sequential lifecycle models

b) Is correct. As per syllabus. This is the correct option of how testing activities should be aligned to the sequential lifecycle model phases

c) Is not correct. As stated in the syllabus, there may be many differences in how the testing activities are aligned

d) Is not correct. As stated in the syllabus a Test Analyst should be involved from the beginning in agile software development

Câu 2: Which of the following answers describes the most appropriate and complete set of activities for the Test Analyst to focus on during test analysis and design?

• A. Analyze the test basis, select test techniques, create high-level test conditions for risk mitigation, create test cases to achieve desired coverage of the test basis, create risk mitigation test cases

• B. Analyze risks, create test conditions to address risks, create high-level test cases to meet test conditions for risk mitigation, create all low-level test cases

• C. Select test techniques, create high-level test cases to meet test conditions, create high-level test cases to mitigate risks, create low level tests cases to achieve desired coverage

• D. Analyze the test basis, identify test conditions at appropriate levels to address the test basis, add test conditions for risk mitigation, select test techniques to achieve desired coverage, design test cases

Answer explanation

a) Is not correct. This option ignores test conditions for risk mitigation and goes straight to test cases, and it is not specific about the objectives of test conditions

b) Is not correct. This option ignores analysis of user stories and omits mention of desired coverage

c) Is not correct. This option ignores test conditions altogether and goes straight to test cases

d) Is correct. With risk mitigation added on to test conditions from the test basis

Câu 3: Which of the following statements does NOT give a good reason why test cases should be reviewed and understood by stakeholders?

• A. Customer and users review the test cases in order to verify them against requirements, business processes and business rules

• B. The test manager reviews the test cases in order to control the work of the test analyst and to create the organization’s test strategy

• C. Testers review test cases written by other testers in order to ensure that the test cases are consistent, understandable and executable by testers other than the author

• D. Developers review test cases written by testers in order to align their understanding of requirements with the testers’ and to align component testing with system testing

Answer explanation

a) Is not correct. Yes, this is one of the good reasons, that is to verify that the test cases match the business processes and rules

b) Is correct. Test cases should be created to comply with the organization’s test strategy, not the other way around

c) Is not correct. Yes, this is another good reason, namely that other testers should be able to understand and execute test cases

d) Is not correct. Yes, developers need to be sure that they have the same understanding of the requirements as the testers in order to catch misunderstandings and also to participate in the optimization of tests

• A. In project HIPPOS the test cases should be written at a high level allowing the testers flexibility in varying the details to achieve higher coverage

• B. In project IQ the test cases should be written at a high level. The testers are business users and they know their business rules and calculations so no need for detailed documentation

• C. In both project IQ and HIPPOS the test cases should be written as low-level test cases, with thorough documentation and detailed procedures

• D. In project IQ the test cases should be written at a low level with documented procedures and traceability to requirements

• E. In project HIPPOS the test cases should be written at a low level with documented procedures and audit trails

Answer explanation

a) Is correct. This is the best recommendation for project HIPPOS, the team has experience in testing and the availability of checklists would ensure a good level of coverage

b) Is not correct. The testers do not have much testing experience, so logical level is not good as they need more detail on what to execute

c) Is not correct. There are no arguments that support the same detailed level of documentation as the characteristics of the two test teams differ

d) Is correct. The testers do not have much test experience and low-level test cases should achieve the high level of coverage

e) Is not correct. There are no arguments that support the need for lowlevel test design for project HIPPOS as the testers are experienced and have access to checklists

• A. The requirements specification for B-OTC is very clear, detailed and exhaustive

• B. B-OTC must be compliant to several regulations and an audit of the tests is mandatory

• C. The testers are domain experts without specific knowledge of formal testing

• D. The sequence of phases an online order will pass through

Answer explanation

a) Is not correct. The level of detail in the specifications will influence the choice of level of test design. For instance, if there no detailed requirements then low-level test design is not an option

b) Is not correct. Audits to support regulatory compliance require low-level test design

c) Is not correct. Testers without formal testing experience executing highlevel test cases will not achieve acceptable levels of coverage

d) Is correct. The sequence of phases is a functional requirement for BOTC and will not influence the choice of level of test design

Câu 6: Which of the following statements is INCORRECT regarding test implementation activities?

• A. Test Analysts may create data to be used with keyword-driven test automation

• B. If a risk-based test strategy is being used, risk priority order may dictate the execution order for the test cases

• C. When creating the test execution schedule, manual and automated test execution are considered to be independent activities

• D. Test Analysts must verify the procedures that gather data for evaluating current status against exit criteria

Answer explanation

a) Is not correct. Unscripted testing should be conducted in time boxed sessions

b) Is not correct. If a risk-based test strategy is being used, risk priority order may dictate the execution order for the test cases

c) Is correct. When creating the test execution schedule, dependencies between manual and automated test execution must be considered. The activities are not independent

d) Is not correct. Test Analysts must verify the procedures that gather data for evaluating current status against exit criteria

• A. Review the calculation algorithms and work with specialists to define a data set for calculation tests

• B. Defer usability testing until UAT and recruit visually impaired testers to join the UAT team

• C. Involve visually impaired users in the review of the user interface design

• D. Spend time with developers to identify operational scenarios to test performance

Answer explanation

a) Is not correct. Is a good suggestion but is a lower priority because the risk is lower

b) Is not correct. Is a good suggestion as the usability risk has a medium likelihood with high impact, but will not mitigate the risk until late in the development life cycle

c) Correct. The usability risk has a medium likelihood with high impact. This is certainly the highest identified risk level, no matter which method is used to calculate the risk level, and it mitigates the risk early in the development life cycle

d) Is not correct. This is a good suggestion but is a lower priority because the risk is lower

• A. The table is incomplete because three Boolean conditions require 23 = 8 rules

• B. The rule R3 is not correct because it potentially offers the credit card option to registered customers whose credit card has expired

• C. The value ‘-‘ (don’t care) for condition C2 in rule R4 should rather be a ‘N/A’ (not applicable) because the system has no information on credit cards for non-registered customers

• D. The value ‘-‘ (don’t care) for condition C3 in rule R4 is incorrect, because if Amount <= 500€ is ‘True’, direct debit should be offered

• E. The table is inconsistent because for a registered customer with an expired credit card and a purchase amount > 500€ both rules R2 and R3 apply
