All CTFL-Foundation Test Inside ISTQB Questions

According to the decision table, Test Case 1 is valid because an employee who is not a car or motorcycle driver cannot claim expenses, as shown in Rule 1. Test Case 3 is valid because a motorcycle driver can claim expenses, as indicated in Rule 2, with expenses claim band A. However, Test Case 2 is invalid because, according to Rule 5, a car driver with a diesel engine greater than 1600cc cannot claim expenses. The expected result should be that the expense claim is not allowed, not band C​​.

Exploratory testing is highly effective when under severe time pressure because it allows testers to simultaneously learn, design, and execute tests. It is a flexible approach that does not require extensive preparation and documentation, making it ideal for situations where time is limited​​.

An independent test function in an organization helps improve defect finding during reviews and testing by providing an unbiased perspective on the software. Independent testers are not influenced by the development team’s constraints and can evaluate the software more objectively. This leads to the identification of defects that might be overlooked by developers who are too close to their own code. Independent testing enhances the quality and reliability of the software by bringing fresh insights and ensuring thorough testing​​.

The amount of testing effort is highly influenced by the predicted number of defects and the subsequent amount of rework required. If a high number of defects are expected, more effort will be needed to identify, document, and retest the defects after they are fixed. This impacts the overall testing workload significantly compared to other factors such as the ratio of developers to testers, which affects team dynamics but not the core testing effort​​.
