Reviews, static analysis and dynamic testing have the same objective –

If you are flying with an economy ticket, there is a possibility that you may get upgraded to business class, especially if you hold a gold card in the airline's frequent flier program. If you don't hold a gold card, there is a possibility that you will get 'bumped' off the flight if it is full and you check in late. This is shown in Figure 4.5. Note that each box (i.e. statement) has been numbered.
Three tests have been run:
Test 1: Gold card holder who gets upgraded to business class
Test 2: Non-gold card holder who stays in economy Test 3: A person who is bumped from the flight What is the statement coverage of these three tests?

Data flow analysis studies

Why are error guessing and exploratory testing good to do?

With a highly experienced tester with a good business background, which approach to defining test procedures would be effective and most efficient for a project under severe time pressure?

Which of the following could be used to assess the coverage achieved for specification-based (black-box) test techniques?
V Decision outcomes exercised W Partitions exercised
X Boundaries exercised
Y State transitions exercised Z Statements exercised

Given the state diagram in Figure 4.6, which test case is the minimum series of valid transitions to cover every state?

When choosing which technique to use in a given situation, which factors should be taken into account?
U previous experience of types of defects found in this or similar systems
V the existing knowledge of the testers
W regulatory standards that apply
X the type of test execution tool that will be used
Y the documentation available
Z previous experience in the development language

Complete statement and branch coverage means

10 Which of the following structure-based test design technique would be most likely to be applied to?
1 Boundaries between mortgage interest rate bands.
2 An invalid transition between two different arrears^ statuses.
3 The business process flow for mortgage approval.
4 Control flow of the program to calculate repayments.

Which of the following would NOT normally form part of a test plan?

Which of the following statements about the relationship between statement coverage and decision coverage is correct?

Which of the following could be a coverage measure for state transition testing?
V All states have been reached.
W The response time for each transaction is adequate.
X Every transition has been exercised.
Y All boundaries have been exercised.
Z Specific sequences of transitions have been exercised.

Which of the following is NOT a white box technique?

What is a key characteristic of structure-based testing techniques?

Error guessing:

Put the test cases that implement the following test conditions into the best order for the test execution schedule, for a test that is checking modifications of customers on a database.
1 Print modified customer record.
2 Change customer address: house number and street name.
3 Capture and print the on-screen error message.
4 Change customer address: postal code.
5 Confirm existing customer is on the database by opening that record.
6 Close the customer record and close the database.
7 Try to add a new customer with no details at all.

In prioritising what to test, the most important objective is to:

In a system designed to work out the tax to be paid:
An employee has £4000 of salary tax free. The next £1500 is taxed at 10%
The next £28000 is taxed at 22%
Any further amount is taxed at 40%
To the nearest whole pound, which of these is a valid Boundary Value Analysis test case?

Which of the following is NOT true of test coverage criteria?

How do experience-based techniques differ from specification-based techniques?

__________ testing assumes that the path of logic in a unit or program
is known.

In a system designed to work out the tax to be paid:
An employee has £4000 of salary tax free. The next £1500 is taxed at 10%
The next £28000 is taxed at 22%
Any further amount is taxed at 40%
Which of these groups of numbers would fall into the same equivalence class?

Postal rates for 'light letters' are 25p up to l0g, 35p up to 50g plus an extra l0p for each additional 25g up to l00g.
Which test inputs (in grams) would be selected using equivalence partitioning?

In which document described in IEEE 829 would you find instructions for the steps to be taken for a test including set-up, logging, environment and measurement?

Which of the following would be an example of decision-table testing for a financial application applied at the system-test level?

Which of the following statements is NOT correct?

Analyse the following highly simplified procedure:
Ask: “What type of ticket do you require, single or return?”
IF the customer wants ‘return’
Ask: “What rate, Standard or Cheap-day?”
IF the customer replies ‘Cheap-day’
Say: “That will be £11:20”
ELSE
Say: “That will be £19:50”
ENDIF
ELSE
Say: “That will be £9:75”
ENDIF
Now decide the minimum number of tests that are needed to ensure that all
the questions have been asked, all combinations have occurred and all
replies given.

Use case testing is useful for which of the following?
P Designing acceptance tests with users or customers.
Q Making sure that the mainstream business processes are tested.
R Finding defects in the interaction between components.
S Identifying the maximum and minimum values
for every input field. T Identifying the percentage of statements exercised by a sets of tests.

Why are both specification-based and structure-based testing techniques useful?
