Software Testing: In this tutorial, we discuss the Evolution of Software Testing, the Software Testing Life Cycle, and the various phases involved in STLC. 8 Phases of Software Testing Life Cycle (STLC) Evolution: 1960’s Trend: 1990’s Trend 2000’s Trend: The… Bugzilla Tutorial: Defect ...
In software testing circles, the term defect is often used interchangeably with bug. However, there is a technical difference. A bug is a defect that results from an error or some issue in code. This is not true for all defects. The two have in common that they need to ...
Defect clustering in software testing refers to a non-uniform distribution of defects throughout the application. It is instead concentrated in a few select areas of the application. This is true, in particular, for large systems, where errors made by developers change ...
Definition:Adefect is an error or a bug, in the application which is created. A programmer while designing and building the software can make mistakes or error. These mistakes or errors mean that there are flaws in the software. These are called defects. When actual result deviates from the ...
Closed:Once the bug is fixed, it is tested by the tester. If the tester feels that the bug no longer exists in the software, tester changes the status of the bug to “closed”. This state means that the bug is fixed, tested and approved. ...
Retest:At this stage the tester do the retesting of the changed code which developer has given to him to check whether the defect got fixed or not. Verified:The tester tests the bug again after it got fixed by the developer. If the bug is not present in the software, he approves that...
Enterprise Resource Planning (ERP) Software belongs to a class of extremely complex software. There are a million lines of codes written for it, as a result of which they are prone to errors. Most large software products have elaborate quality control processes, involving many tasks performed by...
I’m sure that everyone is aware of the “Seven Principles of Software Testing”. These fundamental testing principles help the testing teams to utilize their time and effort to make the testing process an effective one.In this article, we will learn in detail about two principles i.e.Defect...
Software Defect Prediction Based on Classication Rule Mining There has been rapid growth of software development. Due to various causes, the software comes with many defects. In Software development process, testing of software is the main phase which reduces the defects of the software. If a dev...
it is a good method to build software defect prediction model.But there is still lack unified and effective method for SVM's parameter optimization.In this paper,a software defect prediction model based on SVM optimized by genetic algorithm(GA)is proposed,in which the SVM is applied as the ...
