ISTQB 2018 Foundation Software Testing 1

During the test process of an Internet of Things software, a defect was discovered, but it was not corrected due to the release deadline. After the release, it has not yet caused a failure. A test team decides to fix this defect. Which trigger for maintenance is described in this scenario?

Consider the following activities: (i) Implementing an automated test case (ii) Performing the review of the architectural design (iii) Checking grammar and spelling of a user manual (iv) Planning test activities (v) Designing a test case Select all the activities that are part of the testing process.

Consider the piece of code: You executed a predefined set of test cases for this code. Which of the following guarantees that in at least one of these test cases, the while loop was executed at least once?

You test the autopilot system for the airplanes. You want to perform the tests that check the correctness of the communication between two modules of this system: geolocalisation module and engine controller. Which of the following would be the best example of a test basis for designing your tests?

Choose the correct sequence of events.

You test a system that computes the pass/fail result for a student who attends a lecture on software testing. The lecture consists of laboratories and exam. For each of these two parts, a student can get from 0 to 50 points (it is always an integer number). The final evaluation is based on the following rule (Please see image) You want to apply the equivalence partitioning technique to a FinalResult variable. Assume that each test is a pair (L, E). Which set of test cases covers all valid equivalence classes?

You work as a tester in a software house and you concurrently work on two projects. One of them is an internal tool for on-line room reservation, done within an agile life cycle. The other one is a commercial software for managing hospital patients' data, conducted in the waterfall model. In one month, new versions of both systems will be released. You don't have time to perform all the planned tests for both systems. You decide to focus on testing the commercial system. Select the correct answer.

Figure 6.1 presents the set of test cases you want to execute. An arrow from a test case A to B indicates logical dependencies between these test cases: the execution of B is possible only after the execution of A. The number in parentheses represent the priorities of test cases (1= the highest, 5= the lowest). In your strategy, you want to prioritise the execution sequence regarding the test priority. Which test case should be executed as the fifth one?

Consider the collapsed decision table presented in Table 6.1 that describes the business rules for admitting a free bus ticket. Assume that a test consists of three Boolean values corresponding to three conditions. Which of the following tests demonstrates that the business ruled described in the table are contradictory?

You test a system that produced very big output files. Their structure must follow some set of predefined rules. The expected result of a test case is the file that follows these rules. You want to execute a set of test cases. Suppose you have a tool that takes two files as an input and returns TRUE if they are identical and FALSE otherwise. What would be the type of this tool in this case?

Match the actions with the corresponding work product review activities. Action 1 - Distribution of the work product Action 2 - Noting questions and recommendations about the work product Action 3 - Allocating roles Activity a - Individual review Activity b - Planning Activity c - Initiating the review

A tester, together with a developer, architect, and test manager, participates in the inspection of an architectural design of a component. The design was done by the architect. During the inspection, the test manager finds an error int he design. After the inspection, the tester creates the new, corrected version of the design. Using the new design, the developer implements the component. Who performed the debugging?

If there are n binary decisions in the code, and there are no other decisions apart from these ones, what is the total number of coverage elements for the decision coverage?

The client of a system under test is interested primarily in a high availability of this system. One of his requirements is as follows: " The system may be unavailable no more often than 1 hour per week." You prepare a test report designed specifically for the client, regarding the above-mentioned requirement. The report covers the data from the period of last week. Which information should contain this report?

You work as a tester in a project for a dedicated client. You have a set of automated test cases, which are traced back to the functional requirements and to the software components. Each functional requirement is traced back to one or more risk items. Suppose that in a certain moment, risk level of one of the risk items has changed. Using the impact analysis, what can we infer from this fact? (i) Which requirements may be affected by this change? (ii) Which test cases may be affected by this change? (iii) Which software components may be affected by this change?

Which of the below information affects the testing effort and at the same time is the outcome of the testing itself?

A moderator was asked to organise a code review (walkthrough) of a component X for a group of developers. He organised an inspection and invited an author of X and a team of testers. Based on this scenario, which type(s) of the success factors for reviews are missing?

You test the program that takes a sequence of numbers as the input and returns these numbers sorted. Before you start your testing, you get the idea (without referring to any documentation) to check what happens, if you enter the empty set of numbers as the input. This is an example of which technique?

Which of the following gives the best description of a decision table testing?

Which sentence explains correctly the importance of performing regression test regarding the SDLC model chosen?

Software development models must be adapted to:

A system calculates the bonus for airplane pilots. The bonus is based on the total number of flying hours, which is the sum of the number of hours on a flight simulator and the number of hours on regular flights. The business rules R1 - R5 for admitting the bonus are presented in the following decision table. Which of the following sets of test inputs is a minimal set that achieves the equivalence partitioning coverage for the output value? Assume each test input is a pair (s,f), where s denotes the simulator hours and f-flight hours.

Recently, your organisation outsourced the test team for conducting the performance testing. You talk with a developer, who told you that it was a very good idea, because now they - developers - do not need to care so much about the performance issues, as they will be found by the test team. This is an example of:

Which of the following can be the root cause of the fact that a developer implemented an ineffective algorithm?

Which of the following is an example of the analytical test strategy?

Select the right relation between quality assurance, quality control, and testing.

Your company has recently published an official document describing how to perform static analysis of a source code. Can this document be a subject to static analysis?

Which of the following is the benefit of using the checklist-based testing?

Risk level is characterised by:

Table 6.2 shows all the valid transitions of some state machines with three states: Initial, LoginPage, and WelcomePage. Assuming there are only four possible events in the system: GoToLogin, LoginOK, LoginNotOk, LogOut, how many invalid transitions are in this state machine?

Which of the following are the examples of the metrics-based approach and which are the examples of the expert based approach? (i) Planning poker (ii) Wideband Delphi (iii) Burndown chart (iv) Software reliability model

Testers may test the software more efficient than developers, because:

You test the online reservation system for a hotel chain. Consider the artifact (ID003). This artifact is an example of:

You perform an ad-hoc review of the model of a process that realises the following business requirement.: "User can send any file of size at most 1 GB through a web form. If the file size exceed this bound, the system should reject the file, clear the form, and return to the initial state. Otherwise, the system accepts the file." The model under review is presented in Fig. 6.2. What type of defect in the model can you uncover during the review?

A shopping discount system takes as an input the total price T (a positive integer with precision of 1 cent), rounds it to the nearest integer value (in dollars), and basing on this value calculates a discount using the rules presented in Table 6.3. You want to test if the system correctly calculates the discount for a given total price T. Which of the following is a set of boundary values for one of the equivalence classes of a variable T? Assume that you follow 2-point boundary value analysis.

Which of the following is a clear advantage of static testing over dynamic testing?

You write a defect report with an intention to provide developers a sufficient information to reproduce defect as quick as possible. The current form of our report looks as follows: (Please see image) Which additional information in the defect report will be the most beneficial in this scenario?

Consider the use case describing the course enrolment. What is the minimal number of test cases to achieve the standard use-case coverage defined in the Foundation Level Syllabus?
