The oracle assumption:

Is that the tester can routinely identify the correct outcome of a test.

Is that there is some existing system against which test output may be checked.

Is that the tester knows everything about the software under test.

Is that the tests are reviewed by experienced testers.

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

Find as many faults as possible.

Test whatever is easiest to test.

The most important thing about early test design is that it:

Can prevent fault multiplication.

Means inspections are not required.

Integration testing in the small:

Tests interactions between modules or subsystems.

Tests the individual components that have been developed.

Only uses components that form part of the live system.

Tests interfaces to other systems

Which of the following requirements is testable?

The response time shall be less than one second for the specified design load.

The system shall be user friendly.

The safety-critical parts of the system sall contain 0 faults.

The system shall be built to be portable.

An important benefit of code inspections is that they:

Enable the code to be tested before the execution environment is ready.

Can be performed by the person who wrote the code.

Can be performed by inexperienced staff.

Departure from specified behaviour.

Found in the software; the result of an error.

An incorrect step, process or data definition in a computer program.

A human action that produces an incorrect result.

How would you estimate the amount of re-testing likely to be required?

Metrics from previous similar projects

Discussions with the development team

Time allocated for regression testing

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

A measure of test coverage criteria is the percentage of faults found.

Test coverage criteria can be measured in terms of items exercised by a test suite.

A measure of test coverage criteria is the percentage of user requirements covered.

Test coverage criteria are often used when specifying test completion criteria.

Which of the following should NOT normally be an objective for a test?

To prove that the software is correct.

To find faults in the software.

To assess whether the software is ready for release.

To demonstrate that the software doesn't work.

Enough testing has been performed when:

The required level of confidence has been achieved.

The users won't find any serious faults.

Which of the following is a characteristic of good testing in any life cycle model?

Each test level has test objectives specific to that level.

All document reviews involve the development team.

Some, but not all, development activities have corresponding test activities.

Analysis and design of tests begins as soon as development is complete.

Which is the MOST important advantage of independence in testing?

An independent tester may be more effective at finding defects missed by the person who wrote the software.

An independent tester may find defects more quickly than the person who wrote the software.

An independent tester may be more focused on showing how the software works than the person who wrote the software.

An independent tester may be more effective and efficient because they are less familiar with the software than the person who wrote it.

Consider the following statements: <br> i.100% statement coverage guarantees 100% branch coverage. ii.100% branch coverage guarantees 100% statement coverage. iii.100% branch coverage guarantees 100% decision coverage. iv.100% decision coverage guarantees 100% branch coverage. v.100% statement coverage guarantees 100% decision coverage.

ii, iii & iv are True; i & v are False

ii is True; i, iii, iv & v are False

i & v are True; ii, iii & iv are False

ii & iii are True; i, iv & v are False

What is the difference between a project risk and a product risk?

Project risks are the risks that surround the project's capability to deliver its objectives; product risks are potential failure areas in the software or system.

Project risks are potential failure areas in the software or system; product risks are risks that surround the project's capability to deliver its objectives.

Project risks are typically related to supplier issues, organizational factors and technical issues; product risks are typically related to skill and staff shortages.

Project risks are risks that delivered software will not work; product risks are typically related to supplier issues, organizational factors and technical issues.

During which fundamental test process activity do we determine if MORE tests are needed?

Test implementation and execution.

What is the MAIN purpose of a Master Test Plan?

To communicate how testing will be performed.

To communicate how incidents will be managed.

To produce a work breakdown structure.

Which of the following is a major task of test planning?

Evaluating exit criteria and reporting.

Measuring and analyzing results.

What is the main purpose of impact analysis for testers?

To determine how the existing system may be affected by changes

To determine the programming effort needed to make the changes.

To determine what proportion of the changes need to be tested.

To determine how much the planned changes will affect users.

When software reliability measures are used to determine when to stop testing, the best types of test cases to use are those that

Exercise system functions in proportion to the frequency they will be used in the released product

Push the system beyond its designed operation limits and are likely to make the system fail

Exercise unusual and obscure scenarios that may not have been considered in design

Exercise the most complicated and the most error-prone portions of the system

Which of the following is NOT true of incidents?

Incident resolution is the responsibility of the author of the software under test.

Which of the following characterizes the cost of faults?

They are cheapest to find in the early development phases and the most expensive to fix in the latest test phases.

They are easiest to find during system testing but the most expensive to fix then.

Faults are cheapest to find in the early development phases but the most expensive to fix then.
