In functional testing basically the testing of the functions of component or system is done. It refers to activities that verify a specific action or function of the code. Functional test tends to answer the questions like “can the user do this” or “does this particular feature work”. This is typically described in a requirements specification or in a functional specification. … Read more
Software Test types are introduced as a means of clearly defining the objective of a certain level for a program or project. A test type is focused on a particular test objective, which could be the testing of the function to be performed by the component or system. The test objective could be to test non-functional quality characteristics, such … Read more
You have the opportunity to get your application into the hands of users prior to releasing it to the general public. Users can install, test your application, and send feedback to you during this beta testing period. Your beta testers can discover issues with your application that you may have not noticed, such as confusing … Read more
Beta Testing is also known as field testing. It takes place at customer’s site. It sends the system/software to users who install it and use it under real-world working conditions. A beta test is the second phase of software testing in which a sampling of the intended audience tries the product out. (Beta is the second letter of the … Read more
Alpha testing is one of the most common software testing strategy used in software development. Its specially used by product development organizations. This test takes place at the developer’s site. Developers observe the users and note problems. Alpha testing is testing of an application when development is about to complete. Minor design changes can still be made as a … Read more
Acceptance testing is basically done by the user or customer although other stakeholders may be involved as well. The goal of acceptance testing is to establish confidence in the system. Acceptance testing is most often focused on a validation type testing. Acceptance testing may occur at more than just a single level, for example: A Commercial Off the … Read more
In system testing the behavior of whole system/product is tested as defined by the scope of the development project or product. It may include tests based on risks and/or requirement specifications, business process, use cases, or other high level descriptions of system behavior, interactions with the operating systems, and system resources. System testing is most often the final test to … Read more
The tested product is very consistent because the integration testing is basically performed in an environment that almost similar to that of reality Stubs can be written with lesser time because when compared to the drivers then Stubs are simpler to author.
Integration testing tests integration or interfaces between components, interactions to different parts of the system such as an operating system, file system and hardware or interfaces between systems. Integration testing is a key aspect of software testing. After integrating two or more different components together we do the integration testing. Integration testing is done by a specific integration tester … Read more
Testing levels are basically to identify missing areas and prevent overlap and repetition between the development life cycle phases. In software development life cycle models there are defined phases like requirement gathering and analysis, design, coding or implementation, testing and deployment. Each phase goes through the testing. Hence there are various levels of testing. The various … Read more
