Different types of software testing and their Applications
Software testing is a procedural and analytical set of series of activities that makes sure that software performance or the functionality of the software is as per specifications, paradigms, and procedures. Software Testing is the procedure of analyzing a software product to identify differences between expected output and stated input. All the activities like designing, developing, enhancing and maintaining software fall under the process part. The software tester ensures that all the established procedures and paradigms must be followed during the lifecycle of the software development.
Just like any complicated project, developing a software is a liable prospect. The included risks may be related to programs or technical aspects (risks like the developed software will work as per the established standards or modifying/operating the website will be challenging or that the development/maintenance of the project will surpass the budget or the agenda )and the prime objective of a tester is to minimize these plausible risks. And in order to reduce the risks, the Software Tester performs different types of testing techniques. Let us look into some important testing types and why they should be performed:
This is the basic level testing which is performed by the developers before they pass the concluded project to the testers team. They perform unit testing on different distinct units of the source code in order to determine that the individual units are appropriate in accordance with the determined functionality and requirements.
Integration Testing includes testing of integration between individual components or modules of a software (testing where the individual software units are combined and tested as a group). Whether the integrated units work together in order to complete a specified task. Integration testing has two parts top-down approach and bottom-up integration approach. The Top-Down integration is carried out from the top to the bottom of the code hierarchy and moves towards the branches. The Bottom-Up integration approach starts from the lowest level of the code structure. It detects the bugs which could not be uncovered during unit testing. All in all, bugs are detected early in the development cycle.
The testing performed on a complete integrated software which is being developed on the basis of software requirements specifications is called system testing. It is a type of black box testing where information or knowledge about the internal code is not necessary. The external working of the software product is tested in consideration of the requirement documents and the system is tested as an exclusive product. It enables you to test, verify and validate the application architecture as well as client requirements.
It is a black box type of testing in which the system is subjected to excess load and observed whether the system can endure the stress without crashing down. It helps to determine the performance of the system during system failure. Also, to determine security issues at the time of unpredicted system crash.
Performance testing includes testing of system performance on the basis of responsiveness, transactional throughput and the number of concurrent users. It helps in finding the loopholes in the architectural design of the system.
