CTFL_Syll_4.0 Exam Dumps - ISTQB Certified Tester Foundation Level (CTFL) v4.0

BDD emphasizes collaboration between developers, testers, and business stakeholders to define system behavior in a readable format (A). It typically uses theGiven-When-Thensyntax. Unlike unit testing (B), BDD is at a higher level of abstraction. It does not focus solely on non-functional testing (C) and encourages early testing rather than post-development validation (D).

To determine the correct execution order that minimizes the number of configuration switches and respects the dependencies, we need to consider the following:

Initial Configuration:CONF1.

Dependencies:

TC1 depends on nothing.

TC2 depends on TC4.

TC3 depends on TC4.

TC4 depends on nothing.

TC5 depends on TC1.

Configuration Requirements:

TC1 requires CONF2.

TC2 requires CONF2.

TC3 requires CONF1.

TC4 requires CONF1.

TC5 requires CONF2.

Given the initial configuration is CONF1, start with test cases that can run on CONF1 and respect the dependencies. Then switch to CONF2 only when necessary. The optimal order to minimize configuration switches is:

Start withTC4(no dependencies, CONF1).

Continue withTC3(depends on TC4, CONF1).

Switch to CONF2.

ExecuteTC2(depends on TC4, CONF2).

Continue withTC1(no dependencies, CONF2).

Finally, executeTC5(depends on TC1, CONF2).

Therefore, the correct order is:

TC4(CONF1)

TC3(CONF1)

TC2(CONF2)

TC1(CONF2)

TC5(CONF2)

Thus, the answer isA. TC4, TC3, TC2, TC1, TC5.

A test-first approach involves writing tests before writing the code. In this approach, initially, the tests fail because the corresponding functionality is not yet implemented. Afterward, the code is written or modified to make the tests pass. This cycle is repeated iteratively. This method ensures that the code is developed based on predefined tests and helps in identifying issues early in the development process​​.

Decision rules define possiblecombinations of conditions and outcomes.

For this scenario:

Bulk discount has 3 categories(0%, 5%, 10%)

Frequent customer discount has 2 categories(Yes = +5%, No = 0%)

The total number of decision rules is:

3 bulk discount options × 2 frequent customer options = 6 rules.

Thus, the correct answer is6 decision rules (B).

Comprehensive and Detailed Explanation From Exact Extract:

Theshift-left approachfocuses on executing testing activitiesas early as possiblein the software development lifecycle, including static testing, unit tests, and early reviews. Activities like writing tests before code (test-first) and continuous integration are central to this principle.

However, performingnon-functional testing at the system test levelhappenslaterin the lifecycle and doesnotalign with the shift-left philosophy.

“The shift-left approach involves the adoption of practices to move tasks related to testing (e.g., reviews, test design) to earlier stages in the lifecycle.”

(ISTQB CTFL v4.0 Syllabus, Section 2.1.5 – Shift-Left Approach)

“Non-functional testing is often performed at the system test level, but the shift-left approach aims to begin such testing earlier, possibly at integration or even unit levels.”

(ISTQB CTFL v4.0 Syllabus, Section 2.2.2 – Test Types)

Therefore,Option Ddoes not correspond to shift-left practices and is the correct answer.
