The term ‘Pesticide paradox’ refers to the phenomenon where the effectiveness of test cases that are repeated and focused on the same scenarios decreases over time because they tend to find the same defects or no defects at all. This is because the system under test becomes more resistant or immune to the existing test cases, just like pests become more resistant or immune to pesticides over time. To overcome the pesticide paradox, test cases should be regularly reviewed and updated to cover new or changed requirements, scenarios, risks, or defects. Test cases should also be designed to cover different aspects and perspectives of the system under test, such as functionality, usability, performance, security, etc. You can find more information about the pesticide paradox in A Study Guide to the ISTQB® Foundation Level 2018 Syllabus, Chapter 4, Section 4.11.

The statement that use case testing is designed to find defects in the process flow is true, because use case testing is a technique that tests the end-to-end user interactions and outcomes based on use cases or scenarios that describe how the software under test should be used . Use case testing can help to find defects in the process flow, such as missing steps, incorrect sequences, or invalid transitions . The other options are not true statements about use case testing. Option A is false, because use case testing is not designed to be used by real users, but rather by professional testers who design and execute test cases based on use cases or scenarios . Option C is false, because use case testing is not designed to find defects in the data flow, but rather in the process flow. Data flow testing is a different technique that tests how data values are defined, used, and modified by the software under test . Option D is false, because use case testing is not always designed by customers or end users, but rather by testers who analyse the requirements or specifications of the software under test to identify use cases or scenarios .

Pair programming is a software development technique where two programmers work together on the same code at the same workstation. One programmer, called the driver, writes the code while the other programmer, called the navigator, reviews the code and provides feedback and suggestions. Pair programming is not only a coding technique but also an informal review method because it involves constant communication and collaboration between the programmers who check each other’s work and share their knowledge and skills. Pair programming can improve the quality and productivity of software development by reducing defects, increasing code readability, enhancing learning opportunities, and fostering creativity and innovation. Pair programming is usually used in agile methods such as Extreme Programming (XP), Scrum, or Kanban. It is not an alternative term for code inspection, which is a formal review method where a group of reviewers examine a piece of code in a structured and systematic way following predefined rules and roles. It is also not done with developer and tester pairing together because pair programming requires both programmers to have similar levels of expertise and familiarity with the code they are working on. You can find more information about pair programming in A Study Guide to the ISTQB® Foundation Level 2018 Syllabus, Chapter 31.
