Question 15

You are testing a major enhancement to an air traffic control user interface. You have use of a sophisticated pre-production test environment, created specifically for large scale automated regression, performance and security testing. The window for regression testing is limited and must successfully conclude, with no major regressions remaining, before the non-functional testing starts.

You have been using the same version of the TAS for the last few releases, each time completing the automated regression test suite in a single overnight run. However, due to the latest enhancements for the SUT, you believe there is a risk that the test suite may no longer complete overnight and therefore delay performance and security testing.

Which option would be the BEST and MOST cost-efficient approach to mitigate this risk?

    Correct Answer: C

    The best and most cost-efficient approach would be to analyze the regression test suite and remove test coverage duplication and redundancy. By optimizing the existing tests, you can potentially reduce the overall test execution time without incurring the significant costs and complexity associated with creating a mirror of the pre-production test environment or making major changes to coding practices. This approach addresses the risk of the test suite not completing overnight while being mindful of resource usage and cost.

Discussion
FrancisFerreiraOption: C

A would solve the issue at hand, but so would C. Thing is, A is certainly the LEAST cost-effective, for creating a second top-notch pre-prod environment would NOT be cheap. For this reason I would go with C.
