CISA Practice Question: Which THREE of the following are best practices…
Which THREE of the following are best practices for managing system testing in an IS development project?
⚠ Common exam trap
Test-takers frequently assume a production-identical environment is always a best practice, but the CISA exam emphasizes cost-benefit analysis and practical constraints, making 'identical' too absolute; instead, the focus is on using a representative environment and independent testing to ensure quality.

Correct answer & explanation
✓
Create test data that mirrors production data.
Creating test data that mirrors production data is a best practice because it ensures that the test environment closely reflects real-world data volumes, distributions, and edge cases. This approach helps uncover defects that might only appear under production-like data conditions, such as performance bottlenecks, data integrity issues, or boundary value errors. It also validates that the system handles the actual data formats and constraints it will encounter in production.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Create test data that mirrors production data.
Why this is correct
Realistic test data uncovers more issues.
- ✗
Perform testing in a environment identical to production.
Why it's wrong here
While ideal, it is often cost-prohibitive; a representative environment is sufficient.
- ✓
Implement automated regression tests for critical functions.
Why this is correct
Automation saves time and ensures repeatability.
- ✓
Use an independent test team separate from developers.
Why this is correct
Independence increases objectivity.
- ✗
Developers should test their own code thoroughly.
Why it's wrong here
Self-testing can miss defects due to bias.
