WHITE Box Testing

by

White Box Testing is software testing technique in which internal structure, design and coding of software are tested to verify flow of input-output and to improve design, usability and security. In white box testing, code is visible to testers so it is also called Clear box testing, Open box testing, Transparent box testing, Code-based testing and … Read more

V-model in Software testing

by

V- model means Verification and Validation model. Just like the waterfall model, the V-Shaped life cycle is a sequential path of execution of processes. Each phase must be completed before the next phase begins. V-Model is one of the many software development models. Testing of the product is planned in parallel with a corresponding phase of development in V-model. The … Read more

Waterfall model

by

The Waterfall Model was first Process Model to be introduced. It is also referred to as a linear-sequential life cycle model.  It is very simple to understand and use.  In a waterfall model, each phase must be completed fully before the next phase can begin. This type of software development model is basically used for the project which … Read more

Software Development Models

by

The software development models are the various processes or methodologies that are being selected for the development of the project depending on the project’s aims and goals. There are many development life cycle models that have been developed in order to achieve different required objectives. The models specify the various stages of the process and the order … Read more

Incremental testing in software

by

The incremental testing approach has the advantage that the defects are found early in a smaller assembly when it is relatively easy to detect the cause. Another advantage is that all programs are integrated one by one and a test is carried out after each step.  A disadvantage is that it can be time-consuming since stubs and … Read more

Difference between regression testing and retesting

by

Before we start with the differences between regression testing and retesting it’s good to have simple understanding of each topic. Basically, regression testing is carried out to ensure that the existing functionality is working fine and there are no side effects of any new change or enhancements done in the application. In other words, Regression Testing checks to see … Read more

Structural testing

by

The structural testing is the testing of the structure of the system or component. Structural testing is often referred to as ‘white box testing’ or ‘glass box’ or ‘clear-box testing’ because in structural testing we are interested in what is happening ‘inside the system/application’. In structural testing the testers are required to have the knowledge … Read more

Non-functional testing

by

In non-functional testing the quality characteristics of the component or system is tested. Non-functional refers to aspects of the software that may not be related to a specific function or user action such as scalability or security. Eg. How many people can log in at once? Non-functional testing is also performed at all levels like functional testing. Non-functional … Read more
