Types of Tests in an Automated Test Harness

Automated test harnesses are essential tools in modern software development, allowing for continuous testing and rapid feedback. They can include various types of tests to ensure the quality and reliability of the software.

Exam Question

Which four types of tests can be included in an automated test harness?
(choose the best four answers)
A. Integration.
B. Performance.
C. Exploratory.
D. Manual regression.
E. Unit.
F. Functional.

Correct Answers

A. Integration.
B. Performance.
E. Unit.
F. Functional.

Explanation

Correct Answers

A. Integration:
Integration tests verify that different modules or services used by your application work well together. They are often included in automated test harnesses to ensure that various components of the software integrate correctly.

B. Performance:
Performance tests measure how well the software performs under certain conditions, such as load or stress. Including these in an automated test harness helps ensure the software can handle the expected load and perform efficiently.

E. Unit:
Unit tests are the foundation of automated testing. They test individual components of the software to ensure they function as intended. These are typically the most common type of tests included in an automated test harness.

F. Functional:
Functional tests validate that the software performs its intended functions. These tests can be automated to ensure that the software meets the required functional specifications.

Why the Other Options Are Less Appropriate

C. Exploratory:
Exploratory testing is an unscripted, manual process where testers explore the software to find defects. It is not typically automated because it relies on human intuition and creativity.

D. Manual regression:
Manual regression testing involves manually re-running a set of tests to ensure that new code changes have not affected existing functionality. While regression tests can be automated, manual regression itself cannot be included in an automated test harness.

Relevance to the PSD Exam

Understanding the types of tests that can be automated is crucial for the PSD exam. It highlights the importance of maintaining a robust automated testing suite to ensure software quality and reliability.

Key Takeaways

• Integration, Performance, Unit, and Functional tests can all be included in an automated test harness.
• Automated testing helps maintain software quality and provides rapid feedback to developers.

Conclusion

Automated test harnesses are a vital part of modern software development, enabling continuous integration and delivery by automating critical tests. Understanding which types of tests can be included in these harnesses is key to building reliable and high-quality software.
