During which test activity could faults be found most cost effectively?During test planning
The purpose of requirement phase is
To freeze requirements, to understand user needs, to define the scope of testing
How much testing is enough?
The answer depends on the risks for your industry, contract and special requirements
Which of the following is likely to benefit most from the use of test tools providing test capture and replay facilities?
a) Regression testing
b) Integration testing
c) System testing
d) User acceptance testing
Regression testing
How would you estimate the amount of re-testing likely to be required?
Metrics from previous similar projects and discussions with the development team
What studies data flow analysis ?
The use of data on paths through the code.
What is Alpha testing?
Pre-release testing by end user representatives at the developer’s site.
What is a failure?
Failure is a departure from specified behavior.
What are Test compactors ?
Is it really a test if you put some inputs into some software, but never look to see whether the software produces the correct result? The essence of testing is to check whether the software produces the correct result, and to do that, we must compare what the software produces to what it should produce. A test compactor helps to automate aspects of that comparison.
What is the main purpose of Informal review
Inexpensive way to get some benefit
What is the purpose of test design technique?
Identifying test conditions and Identifying test cases
When testing a grade calculation system, a tester determines that all scores from 90 to 100 will yield a grade of A, but scores below 90 will not. This analysis is known as:
Equivalence partitioning
During the testing of a module tester ‘X’ finds a bug and assigned it to developer. But developer rejects the same, saying that it’s not a bug. What ‘X’ should do?
Send to the detailed information of the bug encountered and check the reproducibility
A type of integration testing in which software elements, hardware elements, or both are combined all at once into a component or an overall system, rather than in stages.
Big-Bang Testing
In practice, which Life Cycle model may have more, fewer or different levels of development and testing, depending on the project and the software product. For example, there may be component integration testing after component testing, and system integration testing after system testing.
V-Model
Which technique can be used to achieve input and output coverage? It can be applied to human input, input via interfaces to a system, or interface parameters in integration testing.
Equivalence partitioning
This life cycle model is basically driven by schedule and budget risks” This statement is best suited for…
V-Model
In which order should tests be run?
The most important tests first
The later in the development life cycle a fault is discovered, the more expensive it is to fix. why?
The fault has been built into more documentation,code,tests, etc
What is Coverage measurement?
It is a partial measure of test thoroughness.
What is Boundary value testing?
Test boundary conditions on, below and above the edges of input and output equivalence classes.
What is Fault Masking ?
Error condition hiding another error condition.
What does COTS represent?
Commercial Off The Shelf.
The purpose of wich is allow specific tests to be carried out on a system or network that resembles as closely as possible the environment where the item under test will be used upon release?
Test Environment
What can be though of as being based on the project plan, but with greater amounts of detail?
Phase Test Plan
What is exploratory testing?
Exploratory testing is a hands-on approach in which testers are involved in minimum planning and maximum test execution. The planning involves the cre-ation of a test charter, a short declaration of the scope of a short (1 to 2 hour) time-boxed test effort, the objectives and possible approaches to be used. The test design and test execution activities are performed in parallel typi-cally without formally documenting the test conditions, test cases or test scripts. This does not mean that other, more formal testing techniques will not be used. For example, the tester may decide to use boundary value analysis but will think through and test the most important boundary values without necessarily writing them down. Some notes will be written during the exploratory-testing session, so that a report can be produced afterwards.
What is failure?
Deviation from expected result to actual result
