 Frequency 0, 1, 5, 6; Duration 0, 1, 30, 60, 61 is the correct test set of valid and invalid boundary values applying 2-value boundary value analysis1 . Boundary value analysis is a technique that tests the values at and near the boundaries of an input domain or output range1 . A 2-value boundary value analysis tests two values for each boundary: one valid value and one invalid value1 . For Frequency, the valid boundaries are 1 and 5, so the test set should include one valid value (1 or 5) and one invalid value (0 or 6) for each boundary. For Duration, the valid boundaries are 1 and 60, so the test set should include one valid value (1 or 60) and one invalid value (0 or 61) for each boundary. The other options are incorrect test sets of valid and invalid boundary values applying 2-value boundary value analysis. Option A only includes valid values for each boundary, but not invalid values. Option B includes invalid values that are not adjacent to the boundaries (59 seconds and 60 minutes 1 second). Option D includes more than two values for each boundary (0, 1, 2 for Frequency; 0, 1, 30 for Duration).

Concerned with the behavior of a whole system/product as defined by the scope of a development project. System testing is a level of testing that evaluates the system as a whole against its requirements and specifications. System testing is performed after integration testing and before acceptance testing. System testing covers functional and non-functional aspects of the system, such as usability, performance, reliability, security, etc. A detailed explanation of system testing can be found in A Self-Study Guide For The ISTQB Foundation Exam Certified Tester Foundation Level (CTFL) 2018 Syllabus, pages 75-782.

 These are some of the factors that should be considered to determine whether enough testing has been performed. The exit criteria define the specific goals and requirements for testing completion. The budget limits the resources and time available for testing. The product’s risk profile indicates the areas of highest priority and impact for testing. Sufficient details of the system status allow decisions on whether further testing is needed or not. The other options are not relevant factors for determining enough testing.
