Which scenario is best suited for an integration test?

Verifying that a web app can retrieve data from a database

Checking the response time of a web page under 1000 concurrent users

Checking the visual appearance of a button on a page

Verifying that a function returns the correct output for a given input

What is the primary benefit of running tests locally before committing code?

To eliminate the need for pipeline tests

To catch defects early and reduce feedback time

To automatically deploy to production

A team has integration tests that require a specific database and a message broker. The tests are flaky and sometimes fail due to environment issues. The team wants to reduce flakiness and ensure the tests are reliable. What is the best approach?

Retry the tests automatically on failure.

Run the tests on a Microsoft-hosted agent and install dependencies during the pipeline.

Use a dedicated self-hosted agent with the required dependencies and ensure the environment is stable.

Skip the integration tests in the pipeline and run them manually.

In a YAML pipeline, how can you run tests as part of the build?

By creating a separate repository for tests

By enabling the 'Run tests' option in Azure Boards

By configuring a branch policy to run tests

By adding a script task that executes the test command

What is the main purpose of a unit test?

To check the user interface for usability

To validate a single component or function in isolation

To verify the entire application works end-to-end

To test the performance of the application under load
