ISQI ISTQB Certified Tester Advanced Level - Test Automation Engineering CTAL-TAE (Syllabus v2.0) Sample Questions:

1. You are currently conducting a Proof of Concept (PoC) aimed at selecting a tool that will be used for the development of a TAS. This TAS will exclusively be used by one team within your organization to implement automated UI-level test scripts for two web apps. The two tools selected for the PoC use JavaScript
/TypeScript to implement the automated test scripts and offer capture and playback capabilities. Three test cases for each of the two web apps were selected to be automated during the PoC. The PoC will compare these two tools in terms of their effectiveness in recognizing and interacting with UI widgets exercised by the test cases, to quickly determine whether test automation is possible and which tool is better. Which of the following TAFs is BEST suited for conducting the PoC?

A) A layered TAF with more than three layers
B) A three-layer TAF (test scripts, business logic, core libraries)
C) A two-layer TAF (test scripts, test libraries)
D) A one-layer TAF (test scripts)

2. In a first possible implementation, the automated test scripts within a suite locate and interact with elements of a web UI indirectly through the browsers using browser-specific drivers and APIs, provided by an automated test tool used as part of the TAS. In an alternative implementation, these test scripts locate and interact with elements of the same web UI directly at the HTML level by accessing the DOM (Document Object Model) and internal JavaScript code. The first possible implementation:

A) Has the same level of intrusion as the alternative implementation, and therefore the risk of test scripts producing false positives is the same in both cases
B) Has a lower level of intrusion than the alternative implementation, and therefore its test scripts are less likely to produce false positives
C) Has a higher level of intrusion than the alternative implementation, and therefore its test scripts are less likely to produce false positives
D) Has a lower level of intrusion than the alternative implementation, and therefore its test scripts are more likely to produce false positives

3. You are evaluating the best approach to implement automated tests at the UI level for a web app. Specifically, your goal is to allow test analysts to write automated tests in tabular format, within files that encapsulate logical test steps related to how a user interacts with the web UI, along with the corresponding test data. These steps must be expressed using natural language words that represent the actions performed by the user on the web UI. These files will then be interpreted and executed by a test execution tool. Which of the following approaches to test automation is BEST suited to achieve your goal?

A) Test-driven development
B) Data-driven testing
C) Keyword-driven testing
D) Linear scripting

4. Consider a TAS aimed at implementing and running automated test scripts at the UI level on web apps. The TAS must support cross-browser compatibility for a variety of supported browsers, by ensuring that the same test script will run on such browsers in the same way without making any changes to it. This is achieved by introducing appropriate abstractions into the TAA for connection and interaction with different browsers.
Because of this, the TAS will be able to make direct calls to the supported browsers using each different browser's native support for automation. Which of the following SOLID principles was adopted?

A) Interface segregation principle
B) Dependency inversion principle
C) Liskov substitution principle
D) Open-closed principle

5. A release candidate of a SUT, after being fully integrated with all other necessary systems, has successfully passed all required functional tests (90% were automated tests and 10% were manual tests). Now, it is necessary to perform reliability tests aimed at evaluating whether, under certain conditions, that release will be able to guarantee an MTBF (Mean Time Between Failures) in the production environment higher than a certain threshold (expressed in CPU time). Which of the following test environments is BEST suited to perform these reliability tests?

A) Integration environment
B) Local development environment
C) Preproduction environment
D) Build environment
