Which of the following is a typical test objective? Finding and fixing defects in the test object Maintaining effective communications with developers Validating that legal requirements have been met Building confidence in the quality of the test object. A designer documents a design for a user interface that does not suitably address disabled users because the designer is tired. The programmer implements the user interface in line with the design but as they are working under severe time pressure, they do not include suitable exception handling in their program code for bonus calculations. When the operational system is used, complaints are made by some disabled users about the interface and the company is subsequently fined by the relevant regulatory authority. No one notices that bonus calculations are sometimes incorrect. Which of the following statements is CORRECT? The miscalculation of bonuses is a defect that occasionally occurs The fine received for failing to address some disabled users is a failure The programmer working under severe time pressure is a root cause The design of the user interface includes a designer error.

If the total cost of purchases exceeds $100, the customer gets a 5% discount on subsequent purchases. Otherwise, the customer does not receive a discount. Which test techniques will be MOST helpful in designing test cases based on this requirement? White-box test techniques Black-box test techniques Experience-based test techniques Risk-based test techniques. The system for selling cinema tickets calculates the discount type based on the client's birth year (BY) and on the current year (CY) as follows: Your test suite already contains two test cases: - BY = 1990, CY = 2020, expected result: no discount - BY = 2030, CY = 2029, expected result: print the error message Which TWO of the following test data sets should be added to achieve full valid equivalence partitioning coverage for the discount type? a) BY = 2001, CY = 2065 b) BY = 1900, CY = 1965 c) BY = 1965, CY = 1900 d) BY = 2011, CY = 2029 e) BY = 2000, CY = 2000 a) and d) b) and e) c) and d) a) and c). You are testing a temperature control system for a horticultural cold storage facility. The system receives the temperature (in full degrees Celsius) as the input. If the temperature is between 0 and 2 degrees inclusive, the system displays the message "temperature OK". For lower temperatures, the system displays the message "temperature too low" and for higher temperatures it displays the message "temperature too high". Using two-value boundary value analysis, which of the following sets of test inputs provides the highest level of boundary value coverage? -1, 3 0, 2 -1, 0, 2, 3 -2, 0, 2, 4. You are designing test cases based on the following decision table. So far you have designed the following test cases: - TC1: 19-year-old, unregistered man with no experience; expected result: category A - TC2: 65-year-old, unregistered woman with 5 years of experience; expected result: category B - TC3: 66-year-old, registered man with no experience; expected result: category C - TC4: 65-year-old, registered woman with 4 years of experience; expected result: category D Which of the following test cases, when added to the existing set of test cases, will increase the decision table coverage? 66-year-old, unregistered man with no experience; expected result: category B 55-year-old, unregistered woman with 2 years of experience; expected result: category A 19-year-old, registered woman with 5 years of experience; expected result: category D No additional test case can increase the already achieved decision table coverage. You are applying state transition testing to the hotel room reservation system modeled by the following state transition table, with 4 states and 5 different events: (see table) Assuming all test cases start in the "Requesting" state, which of the following test cases, represented as sequences of events, achieves the highest valid transitions coverage? NotAvailable, Available, ChangeRoom, NotAvailable, Cancel Available, ChangeRoom, NotAvailable, Available, Pay Available, ChangeRoom, Available, ChangeRoom, NotAvailable NotAvailable, Cancel, ChangeRoom, Available, Pay. Your test suite S for a program P achieves 100% statement coverage. It consists of three test cases, each of which achieves 50% statement coverage. Which of the following statements is CORRECT? Executing S will cause all possible failures in P S achieves 100% branch coverage for P Every executable statement in P containing a defect has been run at least once during the execution of S After removing one test case from S, the remaining two test cases will still achieve 100% statement coverage. Why does white-box testing facilitate defect detection even when the software specification is vague, outdated or incomplete? Test cases are designed based on the structure of the test object rather than the specification For each white-box test technique the coverage can be well-defined and easily measured White-box test techniques are very well designed to detect omissions in the requirements White-box test techniques can be used in both static testing and dynamic testing. Which of the following is NOT anticipated by the tester while applying error guessing? The developer misunderstood the formula in the user story for calculating the interest The developer wrote "FA = A*(1+IR^N)" instead of "FA = A*(1+IR)^N" in the source code The developer missed the seminar on new compound interest rate legislation The accuracy of the interest calculated by the system is not precise enough. Which of the following is true about exploratory testing? Test cases are designed before the exploratory testing session starts The tester can perform test execution, but cannot perform test design Exploratory testing results are good predictors of the number of remaining defects During exploratory testing the tester may use black-box test techniques. Which collaborative user story writing practice enables the team to achieve a collective understanding of what needs to be delivered? Planning poker, so that a team can achieve consensus on the effort needed to implement a user story Reviews, so that a team can detect inconsistencies and contradictions in a user story Iteration planning, so that user stories with the highest business value for a customer can be prioritized for implementation Conversation, so that team members can understand how the software will be used. You have just started designing test cases for the following user story. (see table) In all test cases the precondition is as follows: there are only two products available, products A and B. Product A costs $100 and product B costs $110. Which of the following is the BEST example of a test case for this user story? Enter webpage and set filter to show prices between $90 and $100. Expected result: results show product A only. Set maximum price to $110. Expected result: results now include both products A and B Enter webpage. Expected result: the default minimum and maximum prices are $100 and $110 respectively. Add product C to stock, with price $120. Refresh the client's webpage. Expected result: the default maximum price changes to $120 Enter webpage and set filter to show prices between $90 and $115. Expected result: results show both products A and B. Change currency from USD to EUR. Expected result: the filter range changes correctly to EUR values, according to the current exchange rate Enter webpage with three different browsers: Edge, Chrome and Opera. In each browser set filter between $90 and $110. Expected result: results include both products A and B and the results layout is the same in all three browsers. Which of the following BEST define EXIT criteria in a testing project? a) The budget is approved b) Budget runs out c) Test basis is available d) Test cases achieved at least 80% statement coverage e) All test analysts are ISTQB certified at the Foundation Level a) and c) c) and d) b) and d) a) and e). The team wants to estimate the time needed for one tester to execute four test cases for a software component. The team has gathered the following measures of the effort used to execute a single test case: - Best-case scenario: 1 hour - Worst-case scenario: 8 hours - Most likely scenario: 3 hours Given that the three-point estimation technique is being used, what is the final estimate of the time needed to execute all four test cases? 14 hours 3.5 hours 16 hours 12 hours. The table shows the traceability matrix from test cases to requirements. "X" means that a given test case covers the corresponding requirement. You want to prioritize the test cases following the additional coverage prioritization technique. You execute all four test cases. Which test case should be executed as the LAST one? TC1 TC2 TC3 TC4. How can the testing quadrants be beneficial for testing? They help in test planning by dividing the test process into four stages, corresponding to the four basic test levels: component, integration, system, and acceptance testing They help in assessing the high-level coverage (e.g., requirements coverage) based on low-level coverage (e.g., code coverage) They help non-technical stakeholders to understand the different types of tests and that some test types are more relevant to certain test levels than others They help agile teams to develop a communication strategy based on classifying people according to four basic psychological types, and on modelling the relations between them. For a given risk, its risk level is $1,000 and its risk likelihood is estimated as 50%. What is the risk impact? $500 $2,000 $50,000 $200. Which of the following are product risks? a) Scope creep b) Poor architecture c) Cost-cutting d) Poor tool support e) Response time too long a) and d) b) and e) c) and e) d) and e). Which of the following is NOT a valid purpose for a test report? Tracking test progress and identifying areas that require further attention. Providing information on the tests executed, their results, and any issues or defects found Providing information about each defect, such as the steps to reproduce it Providing information on testing planned for the next period. The user reported a software failure. An engineer from the support team asked the user for the software version number where the failure was observed. Based on the version number, the team reassembled all the files that made up the release. This later allowed a developer to perform analysis, find the defect, and fix it. Which of the following enabled the above activity to be performed by the team? Risk management Test monitoring and control Whole-team approach Configuration management. Consider the following defect report for a Book Lending System Which of the following is MOST likely to help the developer reproduce the failure quickly? Adding information about which users and which books the issue affects to the "Description" section Filling in the missing value for the "Priority" field Adding memory dumps and database snapshots taken after each step described in the "Steps to Reproduce" section to the "Attachments" section Repeating the same test case for different environments and writing defect reports for each of them separately. Given the following test tool categories: i. Collaboration tools ii. DevOps tools iii. Management tools iv. Non-functional testing tools v. Test design and implementation tools Tools from which of the categories are MOST likely to facilitate test execution? i, v ii, iv i, iii, v ii, iii, iv. Which of the following is MOST likely to be a risk of test automation?
