What outcome can happen as a result of a high level of test tool intrusion?

• A. A greater need for configuration management controls
• B. Lack of repeatability of some test results
• C. Failures that will not be seen in production
• D. Corruption of data in some test data sets

You work as a TAE for a software vendor that produces bespoke software. Your current project is developing a process control system where data from sensors on the factory floor and human input through a web-based front end undergoes processing on backend platforms. This results in control instructions that are sent to the production line via a message broker.
Your test environment contains all of these components, including the sensors which run in a test harness.
These sensors are third-party components that are still under development, so they are often upgraded. The message broker is also a new third-party component which is still receiving regular patches. This requires frequent re-installation of the TAS, which takes significant manual effort, and there have been several occasions where it was not built correctly due to missing components and had to be rebuilt.
Which action is MOST likely to solve this issue with the TAS?

• A. Connectivity checks after installation to verify interoperability between the TAS and the sensors
• B. Stricter documentation and configuration management of the TAS components
• C. Functional testing of relevant TAS components before installation to verify their interoperability with any upgrade to the sensors
• D. Automated installation from a central repository where component upgrades can be managed

A TAS is used to run on a test environment a suite of automated regression tests, written at the UI level, on different releases of a web app: all executions complete successfully, always providing correct results (i.e., producing neither false positives nor false negatives). The tests, all independent of each other, consist of executable test scripts based on the flow model pattern which has been implemented in a three-layer TAF (test scripts, business logic, core libraries) by expanding the page object model via the facade pattern. Currently the suite takes too long to run, and the test scripts are considered too long in terms of LOC (Lines of Code).
Which of the following recommendations would you provide for improving the TAS (assuming it is possible to perform all of them)?

• A. Split the suite into sub-suites and run each of them concurrently on different test environments
• B. Modify the TAF so that test scripts are based on the page object model, rather than the flow model pattern
• C. Implement a mechanism to automatically reboot the entire web app in the event of a crash
• D. Modify the architecture of the SUT to improve its testability and, if necessary, the TAA accordingly

A suite of automated test cases was run multiple times on the same release of the SUT in the same test environment. Consider analyzing a test histogram that shows the distribution of test results (pass, fail, etc.) for each test case across these runs. Which of the following potential issues is MOST likely to be identified as a result of such an analysis?

• A. Unstable automated test cases
• B. Maintainability issues in automated test cases
• C. Outliers in test execution times
• D. Security vulnerabilities in automated test cases

You are a TAE responsible for a TAS that is used on several products, all of which have complex UIs. A substantial proportion of the automated tests break on a regular basis, usually for reasons associated with the UI. The investigation and maintenance this requires is significantly reducing the productivity of the teams and the return on investment.
You are looking for ways to improve the test cases in this TAS. Which of the following approaches would be MOST appropriate?
a) Artificial intelligence
b) Test histograms
c) Reliability growth modelling
d) Schema validation
e) Operational profiles

• A. c and d
• B. a and b
• C. b and c
• D. d and e
