Question 33 of 40 |Level K2| Number of correct answers: 1 | Credits: 1

An automated test case that should always pass, sometimes passes, and sometimes fails intermittently (non-deterministic behavior) when executed in the same test environment, even if no code (i.e., SUT code, or the test automation code) has been changed.

Which of the following statements about the root cause of this non-deterministic behavior is TRUE?

The specified root cause is a race condition that can be identified by also analyzing the log files of the test case, the SUT, and the TAF
Determining the specified root cause may require, in addition to the TAE, the support of others such as developers and system engineers
The specified root cause must be in the instability of the test environment, since no code has been changed
Determining the specified root cause is certainly easier than if the automated test always fails (deterministic behavior)

Which of the following statements about contract testing is TRUE?

Contract testing, regardless of the approach chosen (provider-driven or consumer-driven) does not need to rely on the creation of stub/mocks since it is used to implement integration testing, not unit/component testing
Contract testing can be viewed as a specialized form of API testing that can be applied to effectively and efficiently test integration between microservices, but only if they interact with REST APIs
The differences between the two approaches to contract testing stem primarily from which side creates the contract: this creation is done by the provider for the provider-driven approach and by the consumer(s) for the consumer-driven approach
Contract testing can be viewed as a specialized form of API testing that can be applied to effectively and efficiently test integration between systems, but only if they interact synchronously

Question 3

Question 16 of 40 |Level K4| Number of correct answers: 1 | Credits: 3

A new TAS allows the implementation of automated data-driven test scripts. All the tasks planned for the initial deployment of this TAS, aimed at installing and configuring the TAS components and provisioning the infrastructure, will be performed manually by a dedicated, specialized team. This TAS is expected to be deployed in the future in other similar environments. As a TAE, you see a risk that the correct and reproducible deployment of the TAS cannot be guaranteed.

Which of the following options is BEST suited for mitigating this risk?

Nothing needs to be done, because the team that will manually perform the specified tasks, as they are specialized, will not make mistakes and will therefore be able to ensure a correct and reproducible deployment
Partition the data tables containing test data used by data-driven test scripts into smaller data tables, using an appropriate logical criterion, to make them more manageable.
Review data-driven test scripts to better organize test libraries by adding test functions containing identical sequences of actions commonly implemented in a relevant number of scripts.
Try to automate most of the tasks related to the installation and configuration of the TAS components and those related to the provisioning of the infrastructure.

Question 40 of 40 |Level K2| Number of correct answers: 1 | Credits: 1

Which of the following descriptions of what some test automation tools can be used to do is TRUE?

Autonomously design intuitive UIs and evaluate them, as well as to evaluate the overall UX (User experience) of an application
Analyze test results, code changes, and metrics to predict potential defects and areas of high risk within an application
Autonomously perform exploratory testing sessions based on test charters to find defects within an application
Make video recordings of UI testing sessions to share with stakeholders to show the functionality and appearance of an application

Question 5

Question 39 of 40 |Level K3| Number of correct answers: 1 | Credits: 2

Some automated regression test scripts run by a TAS in a given test environment make calls to private APIs that require authentication for all requests (the authentication method is the same for all APIs). The SUT is a business-critical system. The following two changes are planned: a change in the authentication method of all APIs and a minor upgrade of the OS (Operating System) in the test environment. You have updated the test scripts to cope with the change in the API authentication method.

Which of the following sequences of activities is BEST to ensure that the test scripts are not adversely affected by these changes?

First upgrade the OS, then implement the change in the API authentication method, and finally run all the updated test scripts
Implement one change at a time and run a subset of the updated test scripts after each change, and finally run all the updated test scripts
First implement the change in the API authentication method, then upgrade the OS, and finally run all the updated test scripts
Implement one change at a time and run a subset of the updated test scripts after each change

Question 6

Question 38 of 40 |Level K4| Number of correct answers: 1 | Credits: 3

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)?

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