Which of the following BEST explains the use of cause-effect graphing?

• Useful to gain a graphical overview of a program's logical structure and are typically used as the basis for creating decision tables.

• Used with the purpose that with a limited set of test cases a reasonable level of coverage can be achieved.

• Used to test the ability of the software to enter into and exit from defined states via valid and invalid transitions.

• Used as a clear method to verify testing of all pertinent combinations of conditions and to verify that all possible combinations are handled by the software under test

How do user stories and testing relate in an agile project?

• User stories provide the flow of events which are to be used by the tester to define test cases.

• User stories provide the user requirement and acceptance criteria being two important inputs for the tester.

• The tester will typically gather and document the user stories, and use them for testing.

• User stories drive the regression test.

A new banking system has 2 customers' types, 2 account types and will operate in two different countries? How many test cases will be needed using the pair wise testing technique and the appropriate 2-wise orthogonal array?

• 2

• 4

• 5

• 8

Tax system A tax system needs to be updated due to new legislation. For a person with a salary of less than 20.000 and who is married, the tax needs to be re-calculated. If the person also has more than two and less than five children, an additional 10% reduction is applicable. How many cases are required to test the 'Tax system' specification using a decision table which is not collapsed?

• 2

• 4

• 6

• 8

If the person also has more than two and less than five children, an additional 10% reduction is applicable. Applying equivalence partitioning to the 'Tax System' specification, which of the following set of equivalence classes is most effective in testing the processing the number of children?

• 2, 4 and 6 children

• 2, 4 and 5 children

• 1, 3 and 6 children

• 3, 4 and 6 children

For a tax system the earnings 4.000 are tax free, the following 1.500 are charged at 10%, the following 28.000 at 20% and the remainder above 40%. All values are rounded to 1. What test case could result from a boundary value analysis?

• 1500

• 33501

• 4499

• 28001

How many cases are left when this decision table is collapsed?

• 2

• 3

• 4

• 5

A temperature unit holds the temperature between - 10 degrees Celcius and 10 degrees Celcius. If the temperature drops below 10 or rises above 10 then an alarm rings. Boundary Value Analysis tests are drawn up using the approach of two test cases per boundary. The temperatures to be tested are:

• 11, 10, -11, -10

• 11, 10, 9, -11, -10, -9

• 11, 9, -9, -11

• 10, 9, -9, -10

A specification states: 'If the fossil is Jurassic in origin then it must be catalogued under Mesozoic post Triassic and cross referred to politic limestone. If it is a tooth, then it must be catalogued under Dental remains. If the fossil is both Jurassic in origin and a tooth it will be catalogued under Mesozoic post Triassic and cross referred to politic limestone only.' The tester analyses this for decision table testing and finds the following conditions and actions:

C1: Jurassic

C2: tooth

A1: Catalogue as Mesozoic post Triassic

A2: Cross refer to politic limestone

A3: Catalogue as Dental remains

How many test cases will a collapsed decision table have?

• 2

• 3

• 4
