  1. Which testing phase verifies that individual components of a healthcare information system work correctly in isolation before integration?

    Answer: Unit testing

    Unit testing verifies individual components or modules in isolation before they are combined with other system elements.

  2. A hospital is implementing a new EHR system and wants to test all interfaces between subsystems. Which type of testing is most appropriate?

    Answer: Integration testing

    Integration testing validates that different subsystems and interfaces work correctly together as a combined system.

  3. During EHR go-live, the system experiences significantly slower response times than during testing. Which type of testing was likely inadequate?

    Answer: Performance testing

    Performance testing, including load and stress testing, should have identified response time degradation under realistic production volumes.

  4. What is the primary purpose of regression testing in a healthcare IT system?

    Answer: Ensure existing functionality still works after changes

    Regression testing ensures that previously working functions have not been broken by new code changes or system updates.

  5. Which document formally defines the testing objectives, scope, approach, and schedule for a healthcare IT implementation?

    Answer: Test plan

    A test plan is the comprehensive document that outlines the overall strategy, scope, resources, and schedule for the testing effort.

  6. A lab system upgrade causes the medication reconciliation module to malfunction unexpectedly. What testing should have caught this?

    Answer: Regression testing

    Regression testing after the lab system upgrade should have validated that the medication reconciliation module continued to function correctly.

  7. Which metric is commonly used to measure defect density during healthcare IT system testing?

    Answer: Number of defects per thousand lines of code

    Defect density, expressed as defects per thousand lines of code (KLOC), is a standard metric for measuring software quality during testing.
