Why error path testing ensures robustness in PyTest - Quick Recap

Recall & Review

beginner

What is error path testing?

Error path testing is a method where tests focus on how software behaves when things go wrong, like invalid inputs or failures.

beginner

Why does error path testing improve software robustness?

Because it checks how software handles unexpected problems, ensuring it doesn't crash and behaves safely under errors.

Give an example of an error path in a login feature.

An error path could be entering a wrong password. Testing this path checks if the system shows an error message and blocks access safely.

How does pytest help in error path testing?

Pytest allows writing tests that expect errors using features like 'pytest.raises' to confirm the software handles errors correctly.

What is the risk of skipping error path testing?

Skipping error path testing can lead to software crashes or security issues when unexpected problems happen in real use.

What does error path testing focus on?

A Testing software performance

B Testing how software handles errors

C Testing normal user actions

D Testing UI design

Error path testing focuses on how software behaves when errors or unexpected inputs occur.

Which pytest feature helps test error handling?

A pytest.fixture

B pytest.param

C pytest.raises

D pytest.mark.skip

pytest.raises is used to check if the code raises expected errors during tests.

Why is error path testing important for robustness?

A It improves software speed

B It makes UI prettier

C It reduces code size

D It ensures software handles failures safely

Error path testing ensures software can handle failures without crashing, making it robust.

What might happen if error path testing is skipped?

A Software may crash on errors

B Software runs faster

C Software uses less memory

D Software has better graphics

Without error path testing, software might crash or behave unpredictably when errors occur.

Which is an example of an error path?

A User enters wrong password

B User logs in successfully

C User views homepage

D User clicks a button

Entering a wrong password is an error path to test how the system handles login failures.

Explain in your own words why testing error paths makes software more robust.

Think about what happens when something goes wrong in real life.

Describe how you would use pytest to test that a function raises an error correctly.

Remember pytest has a special way to check for errors.
