What could be the reasons for these assertion failures?

Incorrect test data

Faulty logic in calculation

Disabled assertions in production

Mismatch with business rules

Insufficient logging

NEW QUESTION 42

Which are common black-box testing techniques?

Equivalence partitioning

Statement coverage

Decision table testing

Path testing

NEW QUESTION 44
According to ISTQB-aligned testing principles, why is exhaustive testing considered impractical?

It only applies to small systems

It misses edge cases

It is time-consuming and cost-ineffective

It can be automated fully

NEW QUESTION 45
Which of the following best describes the primary objective of software testing?

To ensure the software is bug-free

To identify and eliminate coding inefficiencies

To detect discrepancies between actual and expected results

To validate user interface design standards

NEW QUESTION 46
Which type of test coverage metric ensures that all decision outcomes in the code are tested?

Branch coverage

Statement coverage

Stub

Spy

Fake

Dummy

NEW QUESTION 54
What is typically verified through dynamic testing of a web application?

Coding conventions

Testing

NEW QUESTION 58
An experienced tester begins testing a new feature without documentation. They explore inputs, observe behaviors, and use past bug patterns to try edge cases.
Which approaches are they most likely using?

Error guessing

Decision table testing

Exploratory testing

Boundary value analysis

Black-box testing

NEW QUESTION 59
