Testing of software is an evaluation we conduct to deliver information about the quality of a particular software product or system undergoing the test. The software testing techniques also entail the process of executing a program or application with the intention to locate and detect software bugs that is more like defects and errors. Moreover, it also verifies if the software product or service is fit to use. Software test aims to check the following components:
If the project meets the requirements and guides of designs and development
When the software product will really perform its supposed function within an acceptable time frame
If the software or system will attain the stakeholders’ desire and expectations
When the program or application is sufficiently usable
If the system achieves a great general result
When the project responds appropriately to all sorts of inputs
Hence, the primary goal of software testing is to spot software failures so that it can be corrected as early as possible. The covers of software testing also mostly include the evaluation and execution of code in various environments and conditions. Apart from that, testing also includes examining all aspects of code such as does it do what is supposed to do, and does it do what it needs to do.
Software testing approaches
It involves verification and validations.
It involves reviews, walkthroughs, and inspections.
This testing verifies the system behavior without interacting with the software product.
This testing emphasizes the freedom and responsibility of the tester to boost the quality of work gradually.
This testing is also called as clear box testing, glass box testing, or transparent box testing, or structural testing. It verifies the internal structures of a program and an internal perspective of the system.
Black- box testing
This testing is the same as functional testing. It also does not require any programming knowledge. Moreover, it examines the functionality without internal implementation or without seeing the source code.
It involves the knowledge of internal data structures and algorithms. This test also needs to access the source code and executable binary.
1. The traditional waterfall development model
– A group of testers performs the testing. Unit testing is also often done in this process, which is done by the software development team. The separate team will conduct further testing.
2. Agile development model
– In this process, unit tests are written first. Also, the primary purpose of agile is to support continuous integration and lessen defect rates.
The software testing life cycle
Software testing has specific activities and phases. Moreover, the testing life cycle is the activity testers conduct to ensure that the software quality goals are met. Every stage of the life cycle has different criteria, activities, and deliverables. The software also under testing should pass each phase in able to proceed with the next stage. Below are the phases of the software testing life cycle (STLC).
1. Requirements analysis
2. Test planning
3. Test case development
4. Test environment setup
5. Test execution
6. Test cycle closure
Software testing makes the final product satisfying, successful, and usable. Hence, the reason why software undergoes all sorts of tests possible is to ensure quality and functionality. Software tests might look confusing but above all, what matters is the fruit of all the hard work of testers and developers. Basic understanding of how software testing should be is a big help to product development.
