Eight cases are required to test the tax system specification using a decision table that is not collapsed. A decision table is a technique that shows the combinations of conditions and actions for a given scenario. A decision table that is not collapsed contains all possible combinations of conditions and actions, regardless of whether they are valid or not. The conditions for this scenario are:

Salary less than €20 000

Married

Number of children more than two and less than five

The number of cases is equal to the number of possible combinations of these conditions, which is 2^3 = 8. Verified References: [ISTQB® Certified Tester Advanced Level Test Analyst CTAL-TA], Section 3.3.1, page 37.

Examining the test basis is an appropriate task for the Test Analyst during the test analysis phase, as it involves identifying and evaluating the sources of information for test analysis, such as requirements, design documents, user stories, etc. Reviewing test estimates, creating a test execution schedule, and evaluating status against exit criteria are tasks that belong to other phases of testing, such as test planning, test implementation, and test closure.

The most important reason why test conditions should be understandable by business stakeholders is that they should be able to review them and provide feedback to the Test Analyst, as they are the ones who know the business needs and expectations best. This way, the Test Analyst can ensure that the test conditions cover all the relevant aspects of the test basis and are aligned with the business objectives. The other reasons are not as important or not directly related to test conditions. Verified References: ISTQB® Certified Tester Advanced Level Test Analyst CTAL-TA, Section 2.2.1, page 21.
