Which of the following is a typical characteristic of the WALKTHROUGH review type?

  • A. The meeting is led by the author.
  • B. Metrics are gathered throughout.
  • C. Attendees must prepare before the meeting.
  • D. Entry and exit criteria are defined.

Answer : A

You are performing a review of your colleagueג€™s test cases based on the following test basis document:

The Test Cases are as follows:
TC1. Success ג€" valid ג€˜User Nameג€™ and ג€˜Passwordג€™; Customer Menu displayed
TC2. Failure ג€" ג€˜User Nameג€™ field has blank entry; Error Number 12 displayed
TC3. Failure ג€" ג€˜User Idג€™ entered does not exist on database (i.e. unregistered user); Error Number 23 displayed
TC4. Failure ג€" ג€˜Passwordג€™ entered does not match userג€™s password on database; Error Number 24 displayed
You are guided by the following checklist in your review:
C1. There must be one test case to cover success
C2. There must be one test case for each error path (e.g. validation failure)
C3. Each test case must use terminology consistent with the test basis document (field names, error numbering, etc.)
Record a separate defect for each missing test case (checklist items C1 and C2) and for each test case that does not meet checklist item C3.
How many defects should you record?

  • A. 1.
  • B. 2.
  • C. 3.
  • D. 4.

Answer : C

Which of the following BEST describes checklist-based testing?

  • A. An approach to testing whereby the testers dynamically design and execute tests based on their knowledge, exploration of the test item and the results of previous tests.
  • B. An experience-based test technique whereby the experienced tester uses a high-level list of items to be noted, checked or remembered, or a set of rules or criteria against which a product has to be verified.
  • C. A procedure to derive and/or select test cases based on an analysis of the specification, either functional or non-functional, of a component or system without reference to its internal structure.
  • D. A test design technique which ensures that test cases are checked for consistency and completeness against an organisationג€™s list of formatting rules and best practices.

Answer : B

Which of the following is a key difference between black box and white box test design techniques?

  • A. Black box techniques use software code to derive test cases, white box techniques do not.
  • B. White box techniques use functional design specifications to derive test cases, black box techniques do not.
  • C. White box techniques can measure the extent of code coverage, black box techniques can not.
  • D. White box techniques derive test cases from models of the software, black box techniques do not.

Answer : C

A car insurance policy has 3 rates of insurance depending on the age of the driver. For drivers aged between 17 and 25 inclusive they are charged at rate A, drivers aged between 26 and 50 inclusive are charged at rate B and those drivers aged over 50 are charged at rate C.
You are designing test cases, which of the following three ages would test all valid equivalence partitions and therefore test rate A, B and C?

  • A. 26, 45, 50.
  • B. 10, 21, 55.
  • C. 20, 35, 65.
  • D. 17, 25, 50.

Answer : C

A student needs to score at least 50 points to pass. If they score at least 100 points they will achieve a merit and if they score at least 150 points they will achieve a distinction.
Which two values are in the same partition?

  • A. 45 and 55.
  • B. 55 and 120.
  • C. 50 and 60.
  • D. 45 and 170.

Answer : C

A holiday club restricts those booking the holiday, to people between the ages of 18 and 30 inclusive.

  • B. 17, 18, 19, 30, 31, 32.
  • C. 18, 19, 20, 28, 29, 30.

Answer : A

  • B. SS-S3-S2-S1.
  • C. SS-S1-S2-S3.
  • D. SS-S1-S3-S2.

Answer : D

Which statement about deriving test cases from a use case is TRUE?

  • A. Test cases are designed to exercise the defined behaviours.
  • B. There should only be one test case for each use case.
  • C. Test cases can only be derived if there is an activity diagram.
  • D. It is not possible to measure use case test coverage.

Answer : A

  • B. Checking that all decisions have been exercised in a business process.
  • C. Checking that all decisions are based on a numeric value.
