 State testing techniques are a type of dynamic testing techniques that are based on the behavior of the system under test for different input conditions and events. Dynamic testing techniques require the system to be executed with test cases, whereas static testing techniques do not. Static testing techniques can be applied before the code is ready for execution, such as reviews, inspections, walkthroughs, and static analysis. Static testing techniques can help find defects early in the development process, improve the quality of the code, and reduce the cost and effort of dynamic testing. References = ISTQB Certified Tester Foundation Level (CTFL) v4.0 Syllabus, Chapter 4, Section 4.2.1, Page 281; ISTQB Glossary of Testing Terms v4.0, Page 292

This answer is correct because Behavior-Driven Development (BDD) is a test-first approach, where tests that express a shared understanding from stakeholders of how the application is expected to work, are first written in business-readable language (following the Given/When/Then format), and then made executable to drive development. BDD is a collaborative approach that involves testers, developers, business analysts, product owners, and other stakeholders in defining the expected behavior of the application using scenarios that describe the preconditions, actions, and outcomes of the application. BDD scenarios are written using a domain-specific language (DSL) that can be translated into executable test cases using tools such as Cucumber or SpecFlow. BDD aims to improve communication, collaboration, and feedback among the team members, and to deliver software that meets the customer’s needs and expectations. References: ISTQB Glossary of Testing Terms v4.0, ISTQB Foundation Level Syllabus v4.0, Section 3.1.1.4

The problem described involves a software implementation error in a decision statement for calculating a bonus based on the Total Amount of Sales (TAS). The requirement states that if TAS is 300,000€ or more, a bonus should be paid. However, the software incorrectly implements this with "IF (TAS = 300000)" instead of "IF (TAS >= 300000)".

Applying Boundary Value Analysis (BVA) to this situation involves selecting test cases at the boundaries of the input domain, including just below, at, and just above the boundary conditions.

Test Case TC1 = 299999:

This value is just below the boundary (300,000).

Expected Result: No bonus should be paid.

Actual Result: No bonus paid.

TC1 does not highlight the fault because the implemented condition "IF (TAS = 300000)" and the correct condition "IF (TAS >= 300000)" both yield the same result (no bonus).

Test Case TC2 = 300000:

This value is exactly at the boundary.

Expected Result: Bonus should be paid.

Actual Result: Bonus paid.

TC2 does not highlight the fault because the implemented condition "IF (TAS = 300000)" and the correct condition "IF (TAS >= 300000)" both yield the same result (bonus paid).

Test Case TC3 = 300001:

This value is just above the boundary.

Expected Result: Bonus should be paid.

Actual Result: No bonus paid due to the incorrect implementation.

TC3 highlights the fault because the implemented condition "IF (TAS = 300000)" fails to pay the bonus, whereas the correct condition "IF (TAS >= 300000)" would pay the bonus.

BVA focuses on the edges of input ranges where errors are more likely.

The critical values are just below, at, and just above the boundary.

Boundary Value Analysis (BVA):Verification:According to the ISTQB CTFL syllabus, BVA is an essential technique for identifying potential errors at the boundaries of input ranges. This is because developers are more likely to make mistakes at these extremes​​.

Therefore, TC3 (300001) is the test case that would highlight the fault in the software's implementation of the decision condition.

In an agile software development environment with distributed teams, effective communication is crucial. Given the distributed nature and the time zone differences, asynchronous communication methods such as emails are more practical and effective. They ensure that information can be shared and accessed by team members and stakeholders at their convenience, regardless of time zone differences. Regular email updates also provide a documented trail of communication, which can be reviewed and referred back to as needed. Formal face-to-face meetings can be challenging to coordinate across time zones and are not as flexible as email communications​​.
