The agile development model requires the earliest involvement from the test analyst because it is a flexible and iterative approach that delivers software in short cycles called sprints. The test analyst plays a key role in planning, designing, executing, and reporting on the testing activities for each sprint. References =

Pairwise testing is a test design technique that reduces the number of test cases needed to cover all possible combinations of input parameters, by testing only pairs of parameters at a time. It is based on the assumption that most defects are caused by interactions of at most two factors. Pairwise testing is suitable for testing systems that have multiple parameters with discrete values, such as browsers, plug-ins, servers, and operating systems. It can help to find defects that are related to the compatibility and interoperability of the system in different environments. References = ISTQB Advanced Level Test Analyst Syllabus 2019, section 3.2.3; Pairwise Testing or All-Pairs Testing Tutorial with Tools and Examples; Test Design Techniques, section 5.4.

The correct answer isA.Create test data for the keywords that includes error data and verifies the proper error is returned.

Create test data for the keywords that includes error data and verifies the proper error is returned

This is the best way to test the error conditions and still use the keyword-driven tests because it allows the reuse of the existing keywords and functions, while providing different inputs and expected outputs for the test cases.It also ensures that the error checking is automated and consistent, and that the test coverage is adequate1.

A decision table is a technique that shows the possible combinations of conditions and actions for a given problem. To achieve 100% coverage of the decision table, all the combinations of conditions must be tested. The decision table has four conditions: debit card valid, PIN valid, amount approved, and dates available. Each condition has two possible values: yes or no. Therefore, the number of test cases for the decisiontable is 2^4 = 16. However, some of these test cases are invalid or redundant, as they do not reflect the logic of the problem. For example, if the debit card is not valid, then the PIN and the amount are irrelevant. Similarly, if the PIN is not valid, then the amount is irrelevant. Therefore, these test cases can be eliminated from the decision table. After eliminating the invalid or redundant test cases, only eight test cases remain, as shown in the table below:
