Software testing life cycle stlc consists of six phases. The deployment should be done once the testing was. Test analysis is process of analyzing the test basis all documents from which the requirements of a component or system. It gives the information about the areas of the system that may be affected due to the change in the particular section or features of the application. In general, these properties indicate the extent to which the component or system under test.
The test analysis and design activity has the following major tasks. Static analysis can be done by a machine to automatically walk through the source code and detect noncomplying rules. The test basis is the information we need in order to start the test analysis and create our own test cases. We can use the test basis documents to understand what the system should do. Boundary value analysis and equivalence class partitioning both are test case design techniques in black box testing. Software test design techniques static and dynamic testing.
The software is executed with various inputs, and testers compare outputs with expected behavior. Software testing can be stated as the process of verifying and validating that a software or application is bug free, meets the technical requirements as guided by its design and development and meets the user requirements effectively and efficiently with handling all the exceptional and boundary cases. The source from which you derive test information could be. Planning analysis design execution cycles final testing and implementation post implementation test planning product definition phase. Boundary value analysis test case design technique is one of the testing techniques. Test design techniques include control flow testing, data flow testing, branch testing, path testing. Software test design techniques static and dynamic testing the importance of software test techniques. Static analysis vs dynamic analysis in software testing. Lauma fey, 10 software testing tips for quality assurance in software development, aoe. This video explains a highlevel overview of software testing.
In istqb advanced syllabus test analysis and design are considered separate activities even though they can be implemented parallel, integrated or iterative. Static analysis is done after coding and before executing unit tests. It is an expensive, time consuming, and critical approach in system development which requires proper planning of overall testing process. Accordingly, software testing needs to be integrated as a regular and ongoing element in the everyday development process. It lists several tools both commercial and open source and links to some articles. In istqb advanced syllabus test analysis and design are considered separate activities even though they can be implemented parallel, integrated or iterative to facilitate the production to test design work products. It covers a full spectrum of topics from basic principles and underlying theory to organizational and process issues in realworld application. Static testing is usually carried out during the early phase of software development life cycle. A software testing method which is a combination of black box testing method and white box testing method. You could find other testing techniques such as equivalence partitioning, decision table and state transition techniques by clicking on appropriate links boundary value analysis bva is based on testing the boundary values of valid and invalid partitions.
Static testing is useful for testing multiple aspects of a software, including source code, functional and requirement specifications, and design documents and models. In istqb foundation level syllabus test analysis and design were considered together. Levels of capability maturity model cmm steps in rapid application development rad model. Fundamentals of software testing lesson provides you with indepth tutorial.
The main objective of test analysis and design phase is to. Impact analysis is defined as analyzing the impact of changes in the deployed product or application. All these questions are based upon istqb certified tester advanced level syllabus v 2007. Basically its a documentation on which test cases are based, such as requirements, design specifications, product risk analysis, architecture and interfaces. Test suite is a collection of test cases that are used to test a software program to show that it has some specified set of behaviours.
