A tester is writing unit tests for a class that has a hard-coded dependency on a web service. The tests are slow and sometimes fail due to network issues. What is the best way to improve the testability of this class?

Skip the unit test and rely on integration tests that use the real web service.

Use a test that calls the real web service but with a timeout to avoid hanging.

Refactor the class to accept the web service client as a parameter, and use a mock in tests.

Add a static analysis rule to flag classes that depend on web services.

What is technical debt in the context of agile development?

The amount of time spent on testing and debugging

The cost of purchasing and maintaining development tools

The accumulation of code that is difficult to understand and modify due to shortcuts or compromises

The number of open defects in the product backlog

How do static analysis tools help improve code quality?

By automatically refactoring the code to improve its structure

By measuring the test coverage of the code

By replacing the need for code reviews

By identifying potential defects and code smells early in the development process

Which of the following is a common code smell?

A class with many instance variables and methods that are not cohesive

A variable that is used only once in a method

A comment that explains the intent of a complex algorithm

A method that has a single, clear responsibility

Part of the Testing in Agile domain, which makes up ~42% of our current practice bank. ISTQB does not publish an official question count, but from its 90-minute exam (~35–60 total, ~15–25 in this domain), expect 5–8 from this objective — we provide 33 practice questions to prepare you well beyond it.
