Q

Defect

A

Producer’s viewpoint a defect is a product requirement that has not been met or a product attribute possessed by a product or a function performed by a product that is not in the statement of requirements that define the
product
Customer’s viewpoint a defect is anything that causes customer dissatisfaction, whether in the statement of requirements or not.
A defect is an undesirable state.

Q

Exploratory Testing

A

“a style of software testing that emphasizes the personal freedom and responsibility of the individual tester to continually optimize the quality of his/her work by treating test-related learning, test design, test execution, and test result interpretation as mutually supportive activities that run in parallel throughout the project.”

Functional System Testing

A

Functional system testing ensures that the system requirements and specifications are achieved. The process involves creating test conditions for use in evaluating the correctness of the application.

IntegrationTesting

A

This test begins after two or more programs or application components have been successfully unit tested. It is the first level of testing which formally integrates a set of programs that communicate among themselves via messages or files

Q

Model-Based Testing

A

Test cases are based on a simple model of the application. Generally, models are used to represent the desired behavior of the application being tested.

Q

Optimum Point of Testing

A

The point where the value received from testing no longer exceeds the cost of testing.

22
Q

Producers View of Quality

A

Meeting requirements.

23
Q

Quality

A

Is defect free.

quality means “fit for use.”

24
Q

QualityAssurance (QA)

A

The set of support activities needed to provide adequate confidence that processes are established and continuously improved to produce products that meet specifications and are fit for use.

25
Quality Control (QC)
The process by which product quality is compared with applicable standards Its focus is defect detection and removal.
26
RAD Model
A variant of prototyping, is another form of iterative development. The RAD model is designed to build and deliver application prototypes to the client while in the iterative process.
27
Requirements- Based Testing
RBT focuses on the quality of the Requirements Specification and requires testing throughout the development life cycle
28
Reuse Model
Systems should be built using existing components, as opposed to custom-building new components. Clearly suited to Object-Oriented computing environments
29
Risk-Based Testing
Risk-based testing prioritizes the features and functions to be tested based on the likelihood of failure and the impact of a failure should it occur.
30
Scope of Testing
The scope of testing is the extensiveness of the test process.
31
Software Quality Criteria
An attribute of a quality factor that is related to software development.
32
Software Quality Factors
attributes of the software that, if they are wanted and not present, pose a risk to the success of the software and thus constitute a business risk.
33
Software Quality Gaps
The first gap is the producer gap. It is the gap between what was specified to be delivered, meaning the documented requirements and internal IT standards, and what was actually delivered. The second gap is between what the producer actually delivered compared to what the customer expected.
34
Special Causes of Variation
Variation not typically present in the process. They occur because of special or unique circumstances.
35
Spiral Model
Model designed to include the best features from the Waterfall and Prototyping, and introduces a new component risk-assessment.
36
Structural System Testing
designed to verify that the developed system and programs work. The objective is to ensure that the product designed is structurally sound and will function correctly.
37
System Test
The entire system is tested to verify that all functional, information, structural and quality requirements have been met.
38
Testing
1. The process of operating a system or component under specified conditions, observing or recording the results, and making an evaluation of some aspect of the system or component. 2. The process of analyzing a software item to detect the differences between existing and required conditions
39
Testing Schools of Thought
“a belief (or system of beliefs) shared by a group.”
40
Thread Testing
This test technique, which is often used during early integration testing, demonstrates key functional capabilities by testing a string of units that accomplish a specific function in the application.
41
TMMi
A process improvement model for software testing. The Test Maturity Model integration (TMMi) is a detailed model for test process improvement and is positioned as being complementary to the CMMI.
42
Top-Down
Begin testing from the top of the module hierarchy and work down to the bottom using interim stubs to simulate lower interfacing modules or programs. Modules are added in descending hierarchical order.
43
Tracing
A process that follows the flow of computer logic at execution time. Tracing demonstrates the sequence of instructions or a path followed in accomplishing a given task.
44
Unit Test
Testing individual programs, modules, or components to demonstrate that the work package executes per specification, and validate the design and technical quality of the application.
45
User Acceptance Testing
Conducted to ensure that the system meets the needs of the organization and the end user/ customer. It validates that the system will work as intended by the user Essentially, this test validates that the right system was built.
46
Validation
Validation physically ensures that the system operates according to the desired specifications by executing the system functions through a series of tests that can be observed and evaluated
47
Verification
The process of determining whether the products of a given phase of the software development cycle fulfill the requirements established during the previous phase.
48
V-Model
The V-Model is considered an extension of the Waterfall Model. The purpose of the “V” shape is to demonstrate the relationships between each phase of specification development and its associated dynamic testing phase.
49
Waterfall
A development model in which progress is seen as flowing steadily downwards through the phases of conception
50
White-Box Testing
A testing technique that assumes that the path of the logic in a program unit or component is known. consists of testing paths, branch by branch, to produce predictable results. This technique is usually used during tests executed by the development team, such as Unit or Component testing,
