Certified Tester Advanced Level Test Automation Engineering Questions 41–45 (page: 10)

Updated On: 4-Sep-2026

What is considered to be an ADVANTAGE of test automation?

  1. The ability to automate tests that cannot be run manually.
  2. It is cheaper and quicker to develop and maintain than manual testing.
  3. Automated tests will find more defects than manual testing.
  4. Automated tests are more flexible, allowing updates to be easily made when the SUT changes.

Answer(s): A

Explanation:

An advantage of test automation is the ability to automate tests that cannot be run manually, such as large-scale data-driven tests, high-volume performance scenarios, or tests that require continuous execution over long periods. These types of tests would be impractical or impossible to perform manually.



How is automation typically applied in a Waterfall lifecycle model?

  1. Business representatives help to decide on the roadmap for test automation.
  2. Automation is applied at each test level to validate requirements.
  3. Automation is applied in parallel to or after the implementation phase.
  4. It is not possible to automate tests in this lifecycle model.

Answer(s): C

Explanation:

In the Waterfall lifecycle model, automation is typically applied in parallel to or after the implementation phase, since development and testing are distinct sequential phases. This allows automated tests to be created once the system or components are available and stable.



When choosing an automation tool, which would be the BEST option for automation testers who have programming skills?

  1. A low-code or no-code tooling solution.
  2. A tool whose programming language matches that of the system under test.
  3. Avoidance of open-source automation tools.
  4. A commercial-off-the-shelf (COTS) tool.

Answer(s): B

Explanation:

The best option for automation testers with programming skills is a tool that uses the same programming language as the system under test. This maximizes compatibility, simplifies integration, and leverages existing skill sets for efficient test development and maintenance.



Which part of the SUT can be changed to better support test automation?

  1. System environment variables.
  2. Operating system version.
  3. The number of system features.
  4. Internet provider restrictions.

Answer(s): A

Explanation:

System environment variables can be adjusted to better support test automation by configuring paths, test data locations, logging behaviors, or application modes. These changes help make the system more controllable and testable in an automated environment.



What would be a goal of test automation in a preproduction environment?

  1. To verify component functionality.
  2. To build the software and check correctness of the build.
  3. To verify component integration.
  4. To assess non-functional characteristics.

Answer(s): D

Explanation:

A key goal of test automation in a preproduction environment is to assess non-functional characteristics such as performance, reliability, and scalability. Preproduction environments closely mirror production and are ideal for automated testing that evaluates how the system behaves under real-world conditions.
