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.

A decision table is a specification-based test technique that involves creating a table that shows the combinations of inputs and outputs for a system under test based on certain conditions and rules. A decision table can be used to design test cases that cover all possible scenarios and outcomes for a system under test. Some statements about decision tables are:

• I. Generally, decision tables are generated for low risk test items: This statement is false because decision tables can be generated for any level of risk test items depending on the complexity and variability of the system under test. Decision tables are especially useful for testing systems that have many inputs, outputs, conditions, and rules that affect their behavior or performance.
• II. Test cases derived from decision tables can be used for component tests: This statement is true because decision tables can be used to design test cases for any level or type of testing, including component tests. Component tests are tests that verify individual components or units of software in isolation from other components or systems.
• III. Several test cases can be selected for each column of the decision table: This statement is true because each column of the decision table represents a unique combination of inputs and outputs for the system under test based on certain conditions and rules. Therefore, each column can be used as a basis for selecting one or more test cases that cover that combination.
• IV. The conditions in the decision table represent negative tests generally: This statement is false because the conditions in the decision table can represent both positive and negative tests depending on the requirements and expectations of the system under test. Positive tests are tests that verify that the system under test behaves as expected under valid or normal inputs or conditions. Negative tests are tests that verify that the system under test handles errors or exceptions gracefully under invalid or abnormal inputs or conditions.

You can find more information about decision tables in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], Chapter 4, Section 4.2.

Multiple condition coverage is a structure-based test technique that aims to achieve a high level of coverage by testing all possible combinations of conditions and outcomes in each decision point of the code or design of the system under test. Multiple condition coverage verifies that each condition in a decision point has an effect on the outcome and that there are no hidden defects or logical errors in the code or design. Multiple condition coverage requires some knowledge of the internal structure or implementation of the system under test; it focuses on how the system does what it does rather than what it does. Multiple condition coverage is one of the most rigorous and complex structure-based test techniques because it can generate a large number of test cases for each decision point, especially if there are many conditions involved. You can find more information about multiple condition coverage in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], Chapter 4, Section 4.3.

Use case testing is a specification-based test technique that is based on the use cases or scenarios that describe how users interact with the system under test. Use case testing aims to find defects in the process flow or functionality of the system under test by verifying that it behaves as expected according to the use cases or scenarios. Use case testing does not require any knowledge of the data flow or structure of the system under test; it only focuses on what the system does rather than how it does it. Use case testing can be done by professional testers or real users, depending on the level and purpose of testing. Use case testing can also be designed by customers or end users, developers, testers, analysts, or anyone who has access to the use case specifications or user requirements. You can find more information about use case testing in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], Chapter 4, Section 4.2.

Functional testing is an example of black-box dynamic testing. Functional testing is the process of testing the functionality or behavior of a software system based on its requirements or specifications. Functional testing does not require any knowledge of the internal structure or implementation of the system under test; it only focuses on what the system does rather than how it does it. Functional testing is also an example of dynamic testing because it involves executing the software system with selected inputs and observing its outputs and effects on the environment. Dynamic testing is different from static testing, which involves examining the software system without executing it, such as code inspection, static analysis, etc. You can find more information about functional testing and dynamic testing in A Study Guide to the ISTQB® Foundation Level 2018 Syllabus, Chapter 21.

 System integration testing and acceptance testing are two different levels of testing that have different objectives and stakeholders. System integration testing is the process of testing the interactions and interfaces between different components or systems that form a larger system. System integration testing verifies that the system meets its functional and non-functional requirements and works as expected in its intended environment. System integration testing is usually done by testers or developers who have access to the system architecture and design specifications. Acceptance testing is the process of testing the system by the end users or customers to determine if it satisfies their needs and expectations and is ready for deployment or delivery. Acceptance testing verifies that the system complies with the user requirements and business processes and provides value to the stakeholders. Acceptance testing is usually done by users or customers who have access to the user requirements and business scenarios. You can find more information about system integration testing and acceptance testing in A Study Guide to the ISTQB® Foundation Level 2018 Syllabus, Chapter 2, Sections 2.2 and 2.31.

A configuration management tool is a tool that allows users to manage and control the versions and changes of software artifacts, such as code, documents, test cases, etc. A configuration management tool can help prevent the loss of Sam’s updates by:

• Providing a centralized repository where Sam can store and retrieve his test cases and other artifacts
• Keeping track of the history and status of each artifact and allowing Sam to compare and revert to previous versions if needed
• Supporting collaboration and communication among team members by allowing them to share and access the latest versions of the artifacts

The other tools mentioned in the question are not relevant for this scenario because they do not provide the same functionality or benefits as a configuration management tool. For example:

• A. Incident management tool: This tool type allows users to record, track, manage, and report the defects found during testing. It does not help with managing or controlling the versions or changes of test cases or other artifacts.
• C. Test execution tool: This tool type allows users to execute test cases automatically or semi-automatically and compare the actual results with the expected results. It does not help with managing or controlling the versions or changes of test cases or other artifacts.
• D. Backup tool: This tool type allows users to create copies of data or files and store them in a different location or device for recovery purposes. It does not help with managing or controlling the versions or changes of test cases or other artifacts.

You can find more information about configuration management tools in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], Chapter 6, Section 6.4.

One of the basic principles of testing is that for a software system, it is not possible under normal conditions to test all input and output combinations because they are too many and too complex to cover within a reasonable time and budget. Therefore, testers have to select a subset of inputs and outputs that are representative and relevant for testing based on criteria such as requirements, risks, priorities, etc. This principle implies that testing cannot prove that a software system is defect-free or has a certain level of quality because there might be some untested inputs or outputs that could reveal defects or failures. Testing can only provide information about the quality and risk level of a software system based on the observed behavior and results under certain conditions and assumptions. You can find more information about the basic principles of testing in A Study Guide to the ISTQB® Foundation Level 2018 Syllabus, Chapter 11.

Test estimation is the process of predicting the effort, time, and resources required for testing a software system. Test estimation depends on several factors that influence the scope, complexity, and quality of testing. Some of these factors are:

• Characteristics of the product: This factor indicates how difficult or challenging it is to test the software system based on its size, functionality, reliability, usability, performance, security, etc.
• Characteristics of the development process: This factor indicates how well or poorly the software system is developed based on the development methodology, standards, tools, techniques, etc.
• Characteristics of the test process: This factor indicates how effective or efficient the testing process is based on the test strategy, plan, design, execution, evaluation, etc.
• Characteristics of the test team: This factor indicates how skilled or experienced the test team is based on their knowledge, competence, motivation, communication, collaboration, etc.

The outcome of testing of previous test cycle is not a factor on which test estimation is dependent upon because it does not affect the effort, time, or resources required for testing the current test cycle. Rather, it is an outcome or consequence of test estimation that can provide feedback and lessons learned for improving future test estimations. You can find more information about test estimation in Software Testing Foundations: A Study Guide for the Certified Tester Exam, Chapter 22.

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.

You can find more information about boundary value analysis in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], Chapter 4, Section 4.2.
