ABAP Unit and CDS Test Generation Flashcards
(31 cards)
What does the ABAP Unit Test Generation feature in Joule support?
It helps generate unit tests for public methods of global ABAP classes using AI.
From which locations in Eclipse can you start unit test generation?
Project Explorer
Outline View
ABAP Coverage View
ABAP Unit Chat in Joule via:
Quick replies and Freestyle user prompts
Why is it important to understand the problem domain when generating tests with Joule?
Because Joule doesn’t inherently know the intent of the tested code, you must guide the process with your understanding.
What are some best practices for using ABAP Unit Test Generation effectively?
Start small: test 1–3 methods
Review generated code carefully
Customize with prompts like “use inline declarations”
Improve suggestions by manually refining test code
Run your test suite regularly
Resolve failing tests before proceeding
What is the purpose of the Dependency Analysis feature in ABAP Development Tools for Eclipse?
To identify test-unfriendly dependencies in ABAP classes using AI.
What are test-unfriendly dependencies?
Dependencies involving databases, APIs, or other external systems that can lead to unstable or inconsistent test results.
How can you improve test stability when dealing with test-unfriendly dependencies?
By replacing them with test doubles
Why is dependency analysis useful before writing tests?
It helps you understand and isolate unstable parts of the code, leading to more reliable unit testing.
What is the purpose of using test doubles in ABAP unit tests?
To isolate test-unfriendly dependencies and improve the stability and predictability of unit test results.
What kinds of dependencies are typically replaced with test doubles?
Calls to database tables or external APIs.
Why should you use test doubles in your unit tests?
Because they ensure tests run consistently regardless of the system or environment.
What is the purpose of the AI-based Explain feature for ABAP Unit tests?
To provide detailed explanations and understanding of your unit tests.
What key questions can the Explain feature answer about your test code?
What is the tested scope?
What is the general purpose of the test class?
Are there any test smells (e.g., test code duplication)?
Which test patterns are implemented (e.g., creation methods, custom assertions)?
Why is detecting test smells important?
Because they can indicate potential issues like redundant code that may reduce test maintainability or reliability.
Why is refactoring AI-generated unit test code important?
To ensure the test code meets quality standards and fits your preferred coding style.
How can you refactor AI-generated test code effectively?
By using predefined instructions or typing your own refactoring commands in the Joule chat.
Name some example refactoring instructions you can give to Joule for test code.
Avoid hungarian notation (no prefixes)
Create CUT in setup method
Extract and use parameterized custom assertion
Inline and remove custom assertions
Program against interfaces instead of classes
Use inline declarations
Use constructor expressions to fill structures and tables
Write assert statements in one line
What does the instruction “Program against interfaces instead of classes” mean in the context of test code refactoring?
It means designing tests to use interfaces for better abstraction and flexibility, rather than concrete classes.
Why should you split test classes?
To organize tests thematically and reduce code duplication.
What is the benefit of splitting a test class into two test classes and one helper class?
It improves code structure and makes tests easier to maintain.
When should you consider splitting a test method?
When it tests different aspects instead of one focus
When it gets too large
When it has too many assertions
What is the purpose of the AI-assisted CDS test class generation?
To generate automated ABAP Unit tests for CDS entities, providing basic test coverage and improving developer efficiency.
What framework is used to test CDS entities?
The CDS Test Double Framework.
What must be inserted into a CDS test double to test a CDS entity?
Test data, which is returned when the CDS under test (CUT) is executed.
