ISQI CTAL-TAE_V2 Exam Syllabus Topics:

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

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

2. (Which of the following statements about how test automation is applied across different software development lifecycle models is TRUE?)

A) In Agile software development, automated regression test suites sometimes grow so large that they can become difficult to maintain, and thus, it becomes crucial to invest in test automation at multiple test levels
B) Unlike Agile software development, where automated unit tests are written by developers, often in a test-first fashion, in a V-model, automated unit tests are written by testers as part of unit testing
C) In Agile software development, regardless of context (e.g., type of application to be developed, tools available), test automation must be based on the test automation distribution known as the test pyramid model
D) In a Waterfall model, automated tests are usually executed only during the last phase of the development lifecycle, but their implementation occurs in the early stages

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)?

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

4. An API's response to a request made to the corresponding endpoint should return some specific data about a payment transaction in JSON format. In particular, your goal is to write the test automation code, keeping it as short as possible, aimed at determining whether that response includes certain properties (transaction_id, amount, status, timestamp) with the data types and formats expected. Assuming that the TAF provides all the necessary support to validate the specified API response, how would you BEST achieve your goal?

A) Specify the schema for the expected response data (properties, data types, and formats) and validate the actual response data against this schema
B) Use an artificial intelligence algorithm based on machine learning and image recognition to implement a self-healing capability
C) Write custom code that parses the actual response data and checks whether the extracted properties, data types, and formats are as expected
D) Write a single assertion for each property to check whether the data types and formats for that property are as expected in the actual response

5. Consider choosing an approach for the automated implementation of manual regression test suites written at the UI level for some already developed web apps. The TAS is based on a programming language that allows the creation of test libraries and provides a capture/playback feature that allows recognition and interaction with all widgets in the web UIs being tested. The automated tests will be implemented by team members with strong programming skills. The chosen approach should aim to reduce both the effort required to maintain automated tests and the effort required to add new automated tests. Which of the following approaches would you choose?

A) Capture/playback
B) Test-Driven Development (TDD)
C) Structured scripting
D) Linear scripting
