The fundamental test process activity where the sufficiency of testing and resulting information are assessed is Evaluating exit criteria and reporting. This activity involves checking whether the test objectives have been met and whether there are any unresolved issues or risks that could affect the release or deployment decision. This activity also involves preparing and communicating a test summary report that summarizes the test activities and results and provides recommendations and feedback for improvement. You can find more information about Evaluating exit criteria and reporting in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], Chapter 3, Section 3.5.

The requirement given in the image specifies an additional fee of $3 that is charged during the weekend, with some exceptions and discounts based on the age of the visitors. To test this requirement, we can use boundary value analysis, which is a specification-based test technique that involves testing the values at or near the boundaries of an equivalence partition. An equivalence partition is a set of values that are expected to be treated in the same way by the system under test. For example, based on the requirement, we can identify the following equivalence partitions for the input age:

• EP1: Age < 0 (invalid)
• EP2: Age = 0 (valid, no charge)
• EP3: 0 < Age < 7 (valid, no charge)
• EP4: Age = 7 (valid, 20% discount)
• EP5: 7 < Age < 13 (valid, 20% discount)
• EP6: Age = 13 (valid, 20% discount)
• EP7: 13 < Age < 65 (valid, full charge)
• EP8: Age = 65 (valid, 50% discount)
• EP9: Age > 65 (valid, 50% discount)

The boundary values for each equivalence partition are the values at or near the edges of the partition. For example, the boundary values for EP3 are 1 and 6. The boundary values for EP4 are 6 and 7. The boundary values for EP5 are 7 and 12. And so on.

To test this requirement using boundary value analysis, we need to select one value from each boundary and test it with different combinations of weekend and weekday. For example, we can select the following values:

• BV1: Age = -1 (from EP1)
• BV2: Age = 0 (from EP2 and EP3)
• BV3: Age = 6 (from EP3 and EP4)
• BV4: Age = 7 (from EP4 and EP5)
• BV5: Age = 12 (from EP5 and EP6)
• BV6: Age = 13 (from EP6 and EP7)
• BV7: Age = 64 (from EP7 and EP8)
• BV8: Age = 65 (from EP8 and EP9)
• BV9: Age = 66 (from EP9)

We can then create test cases using these values and different combinations of weekend and weekday. For example:

• TC1: Age = -1, Weekend = Yes -> Invalid input
• TC2: Age = -1, Weekend = No -> Invalid input
• TC3: Age = 0, Weekend = Yes -> No charge
• TC4: Age = 0, Weekend = No -> No charge
• TC5: Age = 6, Weekend = Yes -> No charge
• TC6: Age = 6, Weekend = No -> No charge
• TC7: Age = 7, Weekend = Yes -> $2.40 ($3 - 20% discount)
• TC8: Age = 7, Weekend = No -> No charge
• TC9: Age = 12, Weekend = Yes -> $2.40 ($3 - 20% discount)
• TC10: Age = 12, Weekend = No -> No charge
• TC11: Age = 13, Weekend = Yes -> $2.40 ($3 - 20% discount)
• TC12: Age = 13, Weekend = No -> No charge
• TC13: Age = 64, Weekend = Yes -> $3
• TC14: Age = 64, Weekend = No -> No charge
• TC15: Age = 65, Weekend = Yes -> $1.50 ($3 - 50% discount)
• TC16: Age = 65, Weekend = No -> No charge
• TC17: Age = 66, Weekend = Yes -> $1.50 ($3 - 50% discount)
• TC18: Age =

66, Weekend = No -> No charge

Therefore, we need a minimum of 18 valid test cases to achieve 100% boundary value coverage based on input age.

$3.01 is not a valid output boundary value because it is not a possible output value based on the requirement. The output values can only be $0, $1.50, $2.40, or $3 depending on the input age and weekend status.

Beta testing is a type of acceptance testing that is normally performed by customers or potential customers at their own locations. Beta testing is done after the software product has passed the internal testing and quality assurance processes and is ready for release or deployment. Beta testing allows the customers or users to evaluate the software product in their real environment and provide feedback and suggestions for improvement. Beta testing can also help identify defects, compatibility issues, usability problems, or performance bottlenecks that might not have been detected during the internal testing. You can find more information about beta testing in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], Chapter 2, Section 2.3.

Risk-based testing is an approach to testing that prioritizes and focuses on testing activities based on the level of risk associated with each feature or function of the system under test. Risk-based testing aims to optimize the use of time, resources, and techniques for testing by identifying and addressing the most critical and likely sources of failure or harm in the system under test. Some examples of typical risk-based testing activities are:

• Brainstorming sessions are held with a wide variety of stakeholders to identify possible failures in the system: This activity is part of the risk identification process, which involves gathering information and opinions from different perspectives and sources to discover potential risks in the system under test.
• Tests are prioritized to ensure that those associated with critical parts of the system are executed earlier: This activity is part of the risk analysis and evaluation process, which involves assessing the probability and impact of each risk and ranking them according to their severity and importance.
• The focus of testing is shifted to an area in the system where tests find more defects than expected: This activity is part of the risk mitigation and monitoring process, which involves taking actions to reduce or eliminate the risks and tracking their status and progress.

The evaluation of a risk-management tool to decide which tool to use for future projects is not an example of a typical risk-based testing activity because it is not directly related to testing the system under test based on its risks. Rather, it is an example of a tool selection or evaluation activity, which involves comparing and choosing a tool that can support or enhance the testing process based on criteria such as functionality, usability, reliability, compatibility, cost, etc. You can find more information about risk-based testing in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], Chapter 3, Section 3.4.
