You were given a task to analyze and fix causes of failures in a new system to be released.
Which activity are you performing? Debugging Software testing Requirement elicitation Defect management. In many software organizations the test department is called the Quality Assurance (QA) department. Is this sentence correct or not and why? It is correct. Testing and QA mean exactly the same thing It is correct. These names can be used interchangeably because both testing and QA focus their activities on the same quality issues It is not correct. Testing is something more; testing includes all activities with regard to quality.QA focuses on quality-related processes It is not correct. QA is focused on quality-related processes while testing concentrates on demonstrating that a component or system is fit for purpose and to detect defects. A phone ringing in a neighboring cubicle distracts a programmer causing him to improperly program the logic that checks the upper boundary of an input variable. Later, during system testing, a tester notices that this input field accepts invalid input values. Which of the following correctly describes an incorrectly coded upper bound? The root cause A failure An error A defect. Consider the following testware. Which test activity produces this testware as an output? Test planning Test monitoring and control Test analysis Test design. Which of the following is the BEST example of how traceability supports testing? Performing the impact analysis of a change will give information about the completion of the tests Analyzing the traceability between test cases and test results will give information about the estimated level of residual risk Performing the impact analysis of a change will help selecting the right test cases for regression testing Analyzing the traceability between the test basis, the test objects and the test cases will help in selecting test data to achieve the assumed coverage of the test object. Which of the following BEST explains a benefit of independence of testing? The use of an independent test team allows project management to assign responsibility for the quality of the final deliverable to the test team If a test team external to the organization can be afforded, then there are distinct benefits in terms of this external team not being so easily swayed by the delivery concerns of project management and the need to meet strict delivery deadlines An independent test team can work separately from the developers, need not be distracted with project requirement changes, and can restrict communication with the developers to defect reporting through the defect management system When specifications contain ambiguities and inconsistencies, assumptions are made on their interpretation, and an independent tester can be useful in questioning those assumptions and the interpretation made by the developer. You are working as a tester in the team that follows the V-model. The choise of software development lifecycle (SDLC) model impacts the timing of testing, which of the following statement is NOT true? Dynamic testing cannot be performed early in the SDLC Static testing cannot be performed early in the SDLC Test planning cannot be performed early in the SDLC Acceptance testing can be performed early in the SDLC. Which of the following are advantages of DevOps? i. Faster product release and faster time to market ii. Increases the need for repetitive manual testing iii. Constant availability of executable software iv. Reduction in the number of regression tests associated with code refactoring v. Setting up the test automation framework is inexpensive since everything is automated i, ii, iv are advantages; iii, v are not iii, v are advantages; i, ii, iv are no i, iii are advantages; ii, iv, v are not ii, iv, v are advantages; i, iii are not. You work as a tester in a project on a mobile application for food ordering for one of your clients. The client sent you a list of requirements. One of them, with high priority, says "The order must be processed in less than 10 seconds in 95% of the cases." You created a set of test cases in which a number of random orders were made, the processing time measured, and the test results were checked against the requirements. What test type did you perform? Functional, because the test cases cover the user's business requirement for the system Non-functional, because the measure the system's performance Functional, because the test cases interact with the user interface Structural, because we need to know the internal structure of the program to measure the order processing time. Your test strategy suggests that once a system is going to be retired, data migration shall be tested. As part of what test type is this testing MOST likely to be performed? Maintenance testing Regression testing Component testing Integration testing. The following is a list of the work products produced in the SDLC. i. Business requirements ii. Schedule iii. Test budget iv. Third-party executable code v. User stories and their acceptance criteria Which of them can be reviewed? i and iv can be reviewed; ii, iii and v cannot i, ii, iii and iv can be reviewed; v cannot i, ii, iii, and v can be reviewed; iv cannot iii, iv, v can be reviewed; i and ii cannot. Decide which of the following statements (i-v) are true for dynamic testing and which are true for static testing. i. Abnormal external behaviors are easier to identify with this testing ii. Discrepancies from a coding standard are easier to find with this testing iii. It identifies failures caused by defects when the software is run iv. Its test objective is to identify defects as early as possible v. Missing coverage for critical security requirements is easier to find and fix i, iv, v are true for static testing; ii, iii are true for dynamic testing i, iii, iv are true for static testing; ii, v are true for dynamic testing ii, iii are true for static testing; i, iv, v are true for dynamic testing ii, iv, v are true for static testing; i, iii, iv are true for dynamic testing. Which of the following statements about formal reviews is TRUE? Some reviews do not require more than one role The review process has several activities Documentation to be reviewed is not distributed before the review meeting, with the exception of the work product for specific review types Defects found during the review are not reported since they are not found by dynamic testing. What task may management take on during a formal review? Taking overall responsibility for the review Deciding what is to be reviewed Ensuring the effective running of review meetings, and mediating, if necessary Recording review information such as review decisions. A wine storage system uses a control device that measures the wine cell temperature T (measured in °C, rounded to the nearest degree) and alarms the user if it deviates from the optimal value of 12, according to the following rules: - if T = 12, the system says, "optimal temperatura" - if T < 12, the system says, "temperature is too low!" - if T > 12, the system says, "temperature is too high!" You want to use the 3-point boundary value analysis (BVA) to verify the behavior of the control device. A test input is a temperature in °C provided by the device. What is the MINIMAL set of test inputs that achieves 100% of the desired coverage? 11, 12, 13 10, 12, 14 10, 11, 12, 13, 14 10, 11, 13, 14. Which of the following statements about branch testing is CORRECT? If a program includes only unconditional branches, then 100% branch coverage can be achieved without executing any test cases If the test cases exercise all unconditional branches in the code, then 100% branch coverage is achieved If 100% statement coverage is achieved, then 100% branch coverage is also achieved If 100% branch coverage is achieved, then all decision outcomes in each decision statement in the code are exercised. You are testing a mobile application that allows customers to access and manage their bank accounts. You are running a test suite that involves evaluating each screen, and each field on each screen, against a general list of user interface best practices derived from a popular book on the topic that maximizes attractiveness, ease-of-use, and accessibility for such applications. Which of the following options BEST categorizes the test technique you are using? Black-box Exploratory Checklist-based Error guessing. Which of the following BEST describe the collaborative approach to user story writing? User stories are created by testers and developers and then accepted by business representatives User stories are created by business representatives, developers, and testers together User stories are created by business representatives and verified by developers and testers User stories are created in a way that they are independent, negotiable, valuable, estimable, small, and testable. Consider the following part of a test plan. Testing will be performed using component testing and component integration testing. The regulations require to demonstrate that 100% branch coverage is achieved for each component classified as critical. Which part of the test plan does this part belong to? Communication Risk register Context of testing Test approach. Your team uses planning poker to estimate the test effort for a newly required feature. There is a rule in your team that if there is no time to reach full agreement and the variation in the results is small, applying rules like "accept the number with the most votes" can be applied. After two rounds, the consensus was not reached, so the third round was initiated. You can see the test estimation results in the table below. Which of the following is the BEST example of the next step? The product owner has to step in and make a final decision Accept 13 as the final test estimate as this has most of the votes No further action is needed. Consensus has been reached Remove the new feature from the current release because consensus has not been reached. Which of the following is NOT true regarding the test pyramid? The test pyramid emphasizes having a larger number of tests at the lower test levels The closer to the top of the pyramid, the more formal your test automation should be Usually, component testing and component integration testing are automated using API-based tools For system testing and acceptance testing, the automated tests are typically created using GUI-based tools. During risk analysis the team considered the following risk: The system allows too high a discount for a customer. The team estimated the risk impact to be very high. What can one say about the risk likelihood? It is also very high. High risk impact always implies high risk likelihood It is very low. High risk impact always implies low risk likelihood One cannot say anything about risk likelihood. Risk impact and risk likelihood are independent. Risk likelihood is not important with such a high-risk impact. One does not need to define it. The following list contains risks that have been identified for a new software product to be developed: i. Management moves two experienced testers to another project ii. The system does not comply with functional safety standards iii. System response time exceeds user requirements iv. Stakeholders have inaccurate expectations v. Disabled people have problems when using the system Which of them are project risks? i, iv are project risks; ii, iii, v are not project risks iv, v are project risks; i, ii, iii are not project risks i, iii are project risks; ii, iv, v are not project risks ii, v are project risks; i, iii, iv are not project risks. Which of the following is an example of how product risk analysis influences thoroughness and scope of testing? The test manager monitors and reports the level of all known risks on a daily basis so the stakeholders can make an informed decision on the release date One of the identified risks was "Lack of support of open-source databases", so the team decided to integrate the system with an open-source database During the quantitative risk analysis, the team estimated the total level of all identified risks and reported it as the total residual risk before testing Risk assessment revealed a very high level of performance risks, so it was decided to perform detailed performance efficiency testing early in the SDLC. Which TWO of the following options are common metrics used for reporting on the quality level of the test object? a) Number of defects found during system testing b) Total effort on test design divided by the number of designed test cases c) Number of executed test procedures d) Number of defects found divided by the size of a work product e) Time needed to repair a defect Select TWO options. b) and d) a) and d) a) and e) b) and c). Which of the following pieces of information contained in a test progress report is the LEAST useful for business representatives? Impediments to testing Branch coverage achieved Test progress New risks within the test cycle. |
