A test charter is a document that describes the scope, objective, and approach of an exploratory testing session. It is used mainly in exploratory tests to guide the tester’s actions and record the findings. A test charter may make reference to user stories, requirements, risks, or other sources of information that are relevant to the testing mission. A test charter also contains notes taken during a test session, such as test ideas, test results, bugs, issues, and observations. A test charter is not used to monitor a test process, as it is not a formal metric or report. It is also not used to outline the company test policy, as it is specific to a particular test session and context. References: ISTQB® Foundation Level Agile Tester Syllabus, Section 2.2.3, page 18; ASTQB Agile Tester Certification Resources, Section 2.2.3, page 18; How to Write an Exploratory Test Charter, Creating an Exploratory Testing Charter, What is Exploratory Testing?.

Risk-based testing is a technique that prioritizes testing activities based on the level of risk associated with each feature or requirement. The level of risk is usually calculated by multiplying the probability and impact of each risk. The higher the risk level, the more testing effort should be allocated to mitigate the risk. In this case, the risk level for each option is as follows: A. Risk level = Low x Low = Low B. Risk level = Low x High = Medium C. Risk level = High x High = High D. Risk level = High x Low = Medium Therefore, the highest risk level is C, followed by B and D, and then A. The User Story for the Operator-Instructions module should be tested according to this risk order, starting with C, then B, then D, and finally A. Hence, the answer is B, as it is the second highest risk level and should be tested after C. References: ISTQB Foundation Level Agile Tester Extension Syllabus1, page 16; ISTQB Agile Tester Sample Exam2, question 18.

Testers replace developers in writing unit test automation scripts. Comprehensive Explanation: The integration of development and testing activities in Agile projects is based on the principle of cross-functional teamwork, where all team members collaborate and share their skills and knowledge to achieve a common goal. In the context of testing, this means that testing is not seen as a separate activity or phase, but as an integral part of the development process. Therefore, the following sentences are correct:

• While developers develop automated unit test scripts, testers write automated system level tests. This is an example of how developers and testers can work in parallel and complement each other’s testing efforts. Developers can focus on testing the internal quality of the code, while testers can focus on testing the external quality of the product.
• Developers write acceptance criteria and test cases, together with testers. This is an example of how developers and testers can work together to define and verify the user requirements and expectations. Developers can provide their technical expertise and input, while testers can provide their business and user perspective and feedback.
• Developers and testers may work as a pair to develop and test a feature. This is an example of how developers and testers can work closely and interactively to deliver a feature. Developers and testers can exchange ideas, suggestions, and information, and support each other in the coding and testing tasks.

The following sentence is incorrect:

• Testers replace developers in writing unit test automation scripts. This is not a valid example of the integration of development and testing activities in Agile projects, because it implies that testers take over the responsibility of developers, rather than collaborate with them. Testers should not replace developers in writing unit test automation scripts, because developers have more knowledge and experience in coding and debugging, and because unit testing is an essential part of the development process. Testers should instead work with developers to ensure that the unit test automation scripts are adequate, effective, and maintainable. References: ISTQB® Foundation Level Agile Tester Syllabus1, Section 1.2.1, page 9; ISTQB® Glossary of Testing Terms2, version 4.0, pages 16 and 55.
