iSTQB Previous Exam

Question #1 (1 Point)

Which one of the following answers describes a test condition?

• A) A distinguishing characteristic of a component or system

• B) A testable aspect of a component or system identified as a basis for testing

• C) The degree to which a software product provides functions which meet stated and implied needs when the software is used under specified conditions

• D) Test cases designed to execute combinations of conditions and actions resulting from them

Question #2 (1 Point)

Which of the following statements is a valid objective for testing?

• a) The test should start as late as possible so that development had enough time to create a good product

• b) To validate whether the test object works as expected by the users and other stakeholders

• c) To prove that all possible defects are identified

• d) To prove that any remaining defects will not cause any failures

Question #3 (1 Point)

Which of the following statements correctly describes the difference between testing and debugging?

• a) Testing identifies the source of defects; debugging analyzes the defects and proposes prevention activities

• b) Dynamic testing shows failures caused by defects; debugging eliminates the defects, which are the source of failures

• c) Testing removes faults; but debugging removes defects that cause the faults

• d) Dynamic testing prevents the causes of failures; debugging removes the failures

Answer explanation

Dynamic testing can show failures that are caused by defects in the software. Debugging eliminates the defects, which are the source of failures

Question #4 (1 Point)

Which one of the statements below describes the most common situation for a failure discovered during testing or in production?

• a) The product crashed when the user selected an option in a dialog box

• b) The wrong version of a compiled source code file was included in the build

• c) The computation algorithm used the wrong input variables

• d) The developer misinterpreted the requirement for the algorithm

Answer explanation

A crash is clearly noticeable by the use

Question #5 (1 Point)

Mr. Test has been testing software applications on mobile devices for a period of 5 years. He has a wealth of experience in testing mobile applications and achieves better results in a shorter time than others. Over several months, Mr. Test did not modify the existing automated test cases and did not create any new test cases. This leads to fewer and fewer defects being found by executing the tests. What principle of testing did Mr. Test not observe?

• a) Testing depends on the environment

• b) Exhaustive testing is not possible

• c) Repeating of same tests will not find new defects

• d) Defects cluster together

Answer explanation

Principle #5 says “If the same tests are repeated over and over again, eventually these tests no longer find any new defects. To detect new defects, existing tests and test data may need changing, and new tests may need to be written.” Automated regression testing of the same test cases will not bring new findings

Question #6 (1 Point)

In what way can testing be part of Quality Assurance?

• a) It ensures that requirements are detailed enough

• b) Testing reduces the risk of poor software quality

• c) It ensures that standards in the organization are followed

• d) It measures the quality of software in terms of number of executed test cases

Answer explanation

Testing contributes to the achievement of quality in a variety of ways, e.g., such as reducing the risk of inadequate software quality

Question #7 (1 Point) Which of the following activities is part of the main activity "test analysis" in the test process?

• a) Identifying any required infrastructure and tools

• b) Creating test suites from test scripts

• c) Analyzing lessons learned for process improvement

• d) Evaluating the test basis for testability

Answer explanation

This activity is performed during the test analysis activity (test analysis)

Question #8 (1 Point)

Match the following test work products (1-4) with the right description (A-D).

1. Test suite 2. Test case 3. Test script 4. Test charter

A. A set of test scripts to be executed in a specific test run

B. A set of instructions for the execution of a test

C. Contains expected results

D. Documentation of test activities in session-based exploratory testing

• a) 1A, 2C, 3B, 4D

• b) 1D, 2B, 3A, 4C

• c) 1A, 2C, 3D, 4B

• d) 1D, 2C, 3B, 4A

Answer explanation

Glossary defines the following tests as:

• Test suite: “A set of test scripts or test procedures to be executed in a specific test run.” (1A)

• Test case: “A set of preconditions, inputs, actions (where applicable), expected results and post conditions, developed based on test conditions” (2C)

• Test script: “A sequence of instructions for the execution of a test” (3B)

• Test charter: “Documentation of test activities in session-based exploratory testing” (4D)

Question #9 (1 Point)

How can white-box testing be applied during user acceptance testing?

• a) To check if large volumes of data can be transferred between integrated systems

• b) To check if all code statements and code decision paths have been executed

• c) To check if all work process flows have been covered

• d) To cover all web page navigations

Answer explanation

For acceptance testing, tests are designed to cover all workflows defined in the functional requirements documents.

Question #10 (1 Point)

Which of the following statements comparing component testing and system testing is TRUE?

• a) Component testing verifies the functionality of software modules, program objects, and classes that are separately testable, whereas system testing verifies interfaces between components and interactions between different parts of the system

• b) Test cases for component testing are usually derived from component specifications, design specifications, or data models, whereas test cases for system testing are usually derived from requirement specifications or use cases

• c) Component testing only focuses on functional characteristics, whereas system testing focuses on functional and non-functional characteristics

• d) Component testing is the responsibility of the testers, whereas system testing typically is the responsibility of the users of the system

Answer explanation

Examples of work products that can be used as a test basis for component testing include detailed design, code, data model, component specifications. Examples of work products for system testing include system and software requirement specifications (functional and non-functional) use cases
