CTFL_001 Online Practice Questions and Answers

A garden irrigation system allows the user to specify 2 inputs:

1.

Frequency – The number of times the system should be automatically switched on per day; minimum once per day, maximum 5 times

2.

Duration – The duration of operation, in whole minutes, each time it is switched on; ranging from 1 to 60

Applying 2-value boundary value analysis which of the following options has the correct test set of valid and invalid boundary values?

A. Frequency 1, 5; Duration 1, 60

B. Frequency 0, 1, 5, 6; Duration 59 seconds, 1 minute, 60 minutes, 60 minutes 1 second

C. Frequency 0, 1, 5, 6; Duration 0, 1, 60, 61

D. Frequency 0, 1, 2, 5, 6; Duration 0, 1, 30, 60, 61

Your task is to compile a test execution schedule for the current release of software.

The system specification states the following logical dependencies:

An admin user must create/amend/delete a standard user.

A standard user is necessary to perform all other actions.

The test plan requires that re-tests must be performed first, followed by the highest priority tests. To save time, the test plan states that tests should be scheduled to create test data for the subsequent tests in the schedule.

The following test cases have been designed, with an indication of priority (1 being the highest priority) and whether the test has previously failed.

Which test execution schedule meets the test plan requirements and logical dependencies?

A. a, d, c, b, e

B. a, c, b, d, e

C. e, a, b, c, d

D. e, a, d, c, b

During which test activity could faults be found most cost effectively?

A. Execution

B. Design

C. Planning

D. Check Exit criteria completion

Which of the following statements BEST describes one of the seven key principles of software testing?

A. Automated tests are better than manual tests for avoiding the Exhaustive Testing.

B. Exhaustive testing is, with sufficient effort and tool support, feasible for all software.

C. It is normally impossible to test all input / output combinations for a software system.

D. The purpose of testing is to demonstrate the absence of defects. The purpose of testing is to demonstrate the absence of defects.

Which of the following is usually the test basis for integration testing?

A. Program specification

B. Functional specification

C. Technical specification

D. Requirement specification

Which of the following is most likely to be a benefit of using static techniques?

A. Fewer performance defects.

B. Productivity improvements in the development process.

C. More efficient regression testing.

D. Quick return on investment in static analysis tools.

When assembling a test team to work on an enhancement to an existing system, which of the following has the highest level of test independence?

A. A business analyst who wrote the original requirements for the system.

B. A permanent programmer who reviewed some of the new code, but has not written any of it.

C. A permanent tester who found most defects in the original system.

D. A contract tester who has never worked for the organization before.

A. (i) = S1 – S2 – S3 – S4 – S2 and (ii) = S4 – S2 – S4 – S4 – S4

B. (i) = S1 – S2 – S3 – S4 – S4 and (ii) = S2 –S4 – S4 – S4 – S2

C. (i) = S2 – S3 – S4 – S2 – S2 and (ii) = S4 – S2 – S4 – S4 – S4

D. (i) = S2 – S3 – S4 - S4 – S2 and (ii) = S2 –S3 – S4 –S4 – S4

Which of the following accurately defines the integration testing test level?

A. Test basis includes software and system design, test objects include interfaces, and tests concentrate on the interactions between different parts of a system

B. Test basis includes component requirements, test objects include database modules, and tests concentrate on the behaviour of the system as a whole.

C. Test basis includes business processes, test objects include system configuration and configuration data, and tests concentrate on establishing confidence in the system

D. Test basis includes use cases, test objects include user procedures and tests concentrate on a high level model of system behaviour
