PDI Question #103: Real Exam Question with Answer & Explanation

Question

A developer created this Apex trigger that calls MyClass,myStartmethod: The developer creates a test method that calls MyClase,myStartmethod directly, resulting in 81% overall code coverage. What happens wtier the developer tries to deploy the ... and two classes to production, assuming no other code exists?

Options

• AThe deployment fails because the Apr-MgQM has no code coverage.
• BThe deployment tails because no assertions mett made in the lest method.
• CThe deployment passes became the Apex code has the requited 75% code coverage.
• DThe deployment passes because both classes and the trigger were included ki the deployment.

Explanation

The deployment will fail because while the overall code coverage is 81%, the Apex trigger itself has 0% coverage, and all triggers require at least 1% coverage for deployment to production.

Common mistakes.

• B. While assertions are best practice for robust tests, their absence alone does not necessarily cause deployment failure if the minimum code coverage requirements are met.
• C. The overall 75% code coverage requirement applies to all deployable Apex code combined, but individual deployable components like triggers also have specific minimum coverage requirements (1%).
• D. Including classes and triggers in deployment does not bypass the code coverage requirements, which dictate that each trigger must have at least 1% coverage.
