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?.
