7 Different Types of Software Testing Methodologies


Software testing is done for finding the flaws and errors in a product before it is released in the market. It is done for measuring the effectiveness or performance of a software product or application. It is a prerequisite to making sure that the software does not lead to any failure as it might prove to burn a huge cut off from the pocket at the later phases of software development. Here is a list of the different kinds of software testing methodologies, present in the market:


Black box testing

Black box testing refers to a testing methodology where you cannot find any knowledge of the structure or internal functionality of the system. Here, the testing process is known to treat the system as a closed box or black box. Only, the tester is aware of the formal inputs as well as the expected outputs. But they are not aware of how the program is arriving at those specific outputs. Owing to this, the testing needs to be based on a wide array of functional specifications. Owing to this, black box testing is considered to be a kind of opaque or behavioral testing.

White box testing

Also referred to as code-based testing or structural testing, white box testing contributes to being a process that ensures as well as validates the internal framework, mechanism, components, and objects of a software application. This testing methodology stands second to none in verifying a code, according to the design specifications. In addition to this, it is also known to uncover the different vulnerabilities of an app. It is also regarded as a clear box, glass box or transparent box testing as it visualizes the internal mechanisms of the software.

Acceptance testing

Acceptance testing is regarded as a level of software testing in which a system is tested to ensure acceptability. The ultimate goal for this kind of testing is the evaluation of the compliance of the system, in accordance with the requirements of the business. In addition to this, it is also useful in assessing if the software is acceptable for the delivery.

Acceptance testing involves formal testing, according to the business processes, requirements, and needs of the user. In addition to this, it is also useful in determining if a specific system is capable of satisfying the acceptance criteria.

Automated testing

With the rising advancements in technology as well as mobile eco-space, it becomes really difficult for business organizations for maintaining the efficiency and quality of development of mobile applications. As testing involves the major and critical activities of the business, they are neglected often due to cost and time limitations. This might result in compromised product quality. Test automation is considered to be the best option in this regard as it helps in improving the development process of mobile applications in different ways. 

Automation testing has proved to be of immense relief for testers and developers during various phases of the life cycle of application development. It plays a vital role in improving communication among the product owners, designers, codes. In addition to this, it also enhances the effectiveness of the development team.

Writing codes for the accomplishment of manual testing is known to be a hassle in some process as the testers will require writing long scripts at the time of regression testing. With automation testing, it is possible to detect the bugs during the development stage which in turn can save a lot of time.

Regression testing

Regression testing plays a vital role in identifying different underlying bugs as well as technical flaws, which are present in a specific software program. It is recognized to be the retesting of the past changes of specific software which ensures the optimum efficiency of the software in the latest operating environment.

Regression testing utilizes the top quality of the testing tools such as Selenium, QTP, Rational Functional Tester, SilkTest, which tests the software and prevents any sort of additional mess. Regression testing tools are recognized to be prompter, faster, and safer. In addition to this, they are considered to be more accurate, in comparison to manual software testing.

Regression testing is useful in enhancing additional test coverage within a reduced time. It is effective in understanding and gaining information about problematic bugs and flaws. Besides this, it also stands second to none in enhancing efficiency as well as cost-effectiveness.

Functional testing

Functional testing plays a vital role in understanding each aspect of software for ensuring that it functions properly and correctly. Functional testing plays an integral role in verifying if the system is performing, as per the expectations. Functional testing comes with a wide array of benefits owing to which it has turned out to be the prime choice of companies, offering Software QA Services.

Functional testing stands out of the ordinary in ensuring that the end-user or customer gets the utmost satisfaction. In addition to this, it is capable of producing software or an application, which is free from defects. In addition to this, it stands second to none in ensuring that all the requirements are met.

Exploratory testing

Exploratory testing is recognized to be the testing methodology to find specific defects, faults, and bugs that are driven by different challenging assumptions. This form of testing does not include any expected results. The tester decides what is going to be verified and investigates the correctness of the result.

One of the top reasons why exploratory testing is conducted on a wide scale is because it involves less preparation. Hence, you will be capable of finding bugs faster and quicker. It is considered to be more intellectually stimulating, in comparison to scripted testing. The testers make use of deductive reasoning, on the basis of the past results.

Software testing is essential before the launch of the product because we all commit mistakes. The majority of these mistakes are expensive and involve a huge cut off from the pocket. Software testing is being conducted on a wide scale for finding the specific errors and defects which were made at the development stage.
