ISTQB FOUNDATION LEVEL
(CHAPTER 1) EXAM 2025
QUESTIONS AND ANSWERS
coverage - ....ANSWER ...-The degree to which specified coverage items are
exercised by a test suite expressed as a percentage.
debugging - ....ANSWER ...-Concerned with finding causes of a failure (defects),
analyzing the causes, and eliminating them. Typically the process is:
1. Reproduction of a failure
2. Diagnosis (finding the defect)
3. Fixing the defect
In the case of static testing, this is the process of simply removing it. There is no need
for reproduction or diagnosis, since static testing directly finds the defects, and cannot
cause failures.
defect - ....ANSWER ...-Can be found in documentation, such as requirements
specifications or a test script, in source code, or in a supporting work product such as a
build file. They are created because of human error (mistakes).

, error - ....ANSWER ...-Mistake made by a human because of something such as
time pressure, complexity of work, processes, infrastructure, interactions, because they
are tired or lack the required training.
failure - ....ANSWER ...-Can be caused by errors and defects, as well as
environmental conditions such as when radiation or EM fields cause defects in firmware.
quality - ....ANSWER ...-Degree to which a component, system, or process meets
specified requirements and/or user/customer needs and expectations
quality assurance - ....ANSWER ...-Process oriented preventative approach that
focuses on the implementation and improvement of processes. It works on the basis that
if a good process is followed correctly, then it will generate a good product. It applies
both to development and testing processes and is the responsibility of everyone on the
project.
root cause - ....ANSWER ...-Fundamental reason for the occurrence of a problem.
test analysis - ....ANSWER ...-analyzing the test basis to identify testable features.
Associated test conditions are defined and prioritized, taking the related risks and risk
levels into account. The test basis and the test objectives are also evaluated to identify
defects they may contain and assess their testability.
test basis - ....ANSWER ...-All documents from which the requirements of a
component or system can be inferred. The documentation on which the test cases are
based.
test case - ....ANSWER ...-A set of input values, execution preconditions, expected
results and execution postconditions.
