Q.what is Quality Assurance?
Quality assurance (QA) is a way of preventing mistakes or defects in manufactured products and avoiding problems when delivering solutions or services to customers; which ISO 9000 defines as "part of quality management focused on providing confidence that quality requirements will be fulfilled".
Q.What is Quality Control?
Quality control (QC) is a procedure or set of procedures intended to ensure that a manufactured product or performed service adheres to a defined set of quality criteria or meets the requirements of the client or customer. QC is similar to, but not identical with, quality assurance (QA).
Q.Difference between QA and QC?
Quality Assurance :
1)It is process oriented and focuses on defect prevention.
2)QA is a set of activities for ensuring quality in the processes by which products are developed.
3) QA aims to prevent defects with a focus on the process used to make the product. It is a proactive quality process.
4)The goal of QA is to improve development and test processes so that defects do not arise when the product is being developed.
5)Establish a good quality management system and the assessment of its adequacy. Periodic conformance audits of the operations of the system.
6)Prevention of quality problems through planned and systematic activities including documentation.
7)Everyone on the team involved in developing the product is responsible for quality assurance.
8)QA is a managerial tool.
9)QA is process oriented.
Quality Control:
1)It is product oriented and focuses on defect identification.
2)QC is a set of activities for ensuring quality in products. The activities focus on identifying defects in the actual products produced.
3)QC aims to identify (and correct) defects in the finished product. Quality control, therefore, is a reactive process.
4)The goal of QC is to identify defects after a product is developed and before it's released.
5) Finding & eliminating sources of quality problems through tools & equipment so that customer's requirements are continually met.
6)The activities or techniques used to achieve and maintain the product quality, process and service.
7) QC is a corrective tool.
8) QC is product oriented.
Q.what is user Documentation?
user documentation is a document that describes the way a software product or the way a system should used to obtain the described result.
Q.what is user manual?
user manual is a document that provides information necessary to employ a system to obtain the desired result.
Q.what is software version?
software version is an-initial release of a software associated with complete compilation of the software .
Q.what is document version?
Document version is an initial release of a document as suppose to a revision resulting from an issuing change page to a previous release.
Q.what is test Methodology?
Test Methodology is a three steps step creating test strategy, creating a test plan and executing tests.
Q.What is Bug?
A fault is a program which cause causes the program to perform in an unintended or unanticipated manner.
Q.what is Default?
If software misses some feature or function from what is requirement it is called as default.
Q.What is debugging?
The process of finding and removing the causes of software failures.
Q.What is Base Line?
The Point at which some deliverable product during the software engineering process is put under formal changes control.
Q.What is Software Testing?
A set of activity conducted with the intent of finding errors in software.
Q.what is Fault Masking?
Fault masking is when the presence of one defect hides the presence of another defect. for example: If the "Negative Value" cause a firing of unhandled system exception, the developer will prevent the negative values input.
Q.what is Test procedure?
A document providing detailed instructions for the execution of one or more test case.
Q.what is Application Binary Interface(ABI)?
A specification defining requirements for portability of applications in binary forms across different system platforms.
Q.what is Application programing Interface(API)?
An API is an interface intended to be interpreted by a computer. API testing is the process of software testing APIs, both for internal and public facing data.
Q.what is Boundry value Analysis?
Boundary value analysis is a software testing technique in which tests are designed to include representatives of boundary values in a range. The idea comes from the boundary. Given that we have a set of test vectors to test the system, a topology can be defined on that set.
Q.what is Configuration Management?
configuration management is a process to control and document any changes made during the life of a project revision control, change control and release control are important aspects of configuration management.
Q.What is DTD?
It is define a structure and legal element and attribute of an xml document.
Q.what is socket?
A socket is one end point of a two-way communication link between two programs running on the network . A socket is bound to port number so the application that data is destined to be sent to an endpoint is communication of IP address and a port number.
Q.what is stub?
Stubs are used during Top-down integration testing, in order to simulate the behavior of the lower-level modules that are not yet integrated. Stubs are the modules that act as temporary replacement for a called module and give the same output as that of the actual product.
Q.what is Bug leakage?
A defect which exist during testing yet unfound by the tester which is eventually found by the tester/end-user is also called by leakage .A Bug release is when a particular version of S/W is released with a set of known Bug/Default .These bugs are usually low severity or low priority bugs.
