Question 337 - CTFL-2018 discussion

The correct answer is C, as it describes a benefit of test automation.Test automation is the use of software to control the execution of tests, the comparison of actual outcomes to predicted outcomes, the setting up of test preconditions, and other test control and test reporting functions1.Test automation can have many benefits, such as reduction in repetitive manual work1.This can improve the efficiency and effectiveness of testing by saving time, effort, and resources1. Option A is incorrect, as it does not describe a benefit of test automation, but a factor that influences the selection of test automation tools.Availability of the test automation tool vendor is a factor that affects the availability and support of the tool, which may affect the success of test automation1. Option B is incorrect, as it does not describe a benefit of test automation, but a misconception.Negligible effort to maintain the test assets generated by the tool is not true, as test automation requires regular maintenance and update of the test scripts, data, and expected results to cope with changes in the software under test1. Option D is incorrect, as it does not describe a benefit of test automation, but a drawback.More subjective assessment is not a benefit, as test automation may introduce bias and errors in the test results due to human factors such as lack of skills, knowledge, or experience1.
