Everything to know about the software testing- Methods and types

Software Quality Assurance

Every organization has a set of goals that comes with its expectations. Most business people think that their company’s success depends on matching up their real outcomes with expected results. Before reaching its goals, the company will face the consequence of human error. To ensure a high-quality product, to resolve all types of errors in the product. Software testing plays an essential role in solving this problem for software development companies. Here comes some of the software testing basics that you need to know.

What is software testing?

Software testing is the task of finding bugs in the developed product. It always checks whether the real outcomes meet the expected results as well as helps in the identification of defects, missing gaps, or requirements. Before launching the product to the market, the testing process is undergone. It includes observation, examination, analysis, and evaluation of different aspects of the product. Software testers conduct the testing process through manual testing with automated tools. After completing the testing process, the testers report the outcomes to the development team. Finally, the tested products are delivered to the customers. This is why software testing is important.

Methods of software testing

Various methods are involved in software testing. Software testing methods are chosen by different testers based on their demands and methodologies. Here you will see the most viral software testing methods that are used in almost every software project development.

Black box testing

Black box testing is also referred to as behavioral testing. The software tests the internal structure, plan, and performance, and UI and UX of the product are being tested which are unknown to the testers. Black box testing performs in a functional or non-functional way. But most of the time it chooses a functional mode of testing. This type of testing is named a black box because the product or software is not confessed in advance to the testers. Black box testing is like blindfolding the tester’s eyes and they are not able to see anything inside. The black box testing tries to find bugs in this category.

  • Interface errors
  • Data structure implementation and concepts errors
  • Errors in the database
  • Behavioral or performance errors
  • Error in the beginning or end of the product
  • Improper of misplace function in the software.

White-box testing 

White box testing is known as Glass box testing or transparent box testing. It is also termed as code-oriented testing or structural testing from the customer’s point of view. This type of software testing deals with testing the internal data structure, logic functions, and implementation of different modules. Here the software tester uses their previous code function to extract the proper or exact output, hence it is defined as code-oriented testing. It contains script-based testing and technical testing as a part of the testing phase.

Gray box testing

The grey box testing combines both white box and black-box testing. In Grey box testing, the tester will know partly testing information of the product. In Grey box testing the data structures are partially residing on the different test cases and the testing process takes place as per the tester point of view or through the black box tester. The grey box testing holds the name grey because it is a semi-transparent from the side of the tester. Hence it has the combination of black and white color it gets the shade of grey.

The different types of software testing

There are different types of software testing in practice. The most important categories are functional and non-functional testing along with the manual, system, and automated programming testing types.

Functional testing

The functional testing tells what exactly the system does and also checks how each function of the software application works. This type of testing is used to verify whether the real outcomes match the expected output and the testers no need to work on the source code of the applications.

Unit testing

Unit testing is the starting stage of testing performed by the developers. This type of testing usually focuses on the smaller unit of software designs. The testing process is performed on a single unit or a group of units to check the software functionality.

Integration testing

Integration testing combines the individual test unit into a grouped testing which is usually performed by the developers. This type of testing Is crucial because it exposes the faults of the software between integrated units. The integration testing takes up the unit components that are already tested and constructs a structural program.

Interface testing

The interface testing is carried out when the software offers support for one or more interfaces such as the command-line interfaces, graphical user interface, and application programming interface to know how they perform the function with its users or software. This testing process acts as a medium for software to receive the input from the user and send the output to the user.

Non-functional testing

This testing function sees how well the system performs under certain conditions. The most common types of non-function testing are performance, load, stress, security, and compatibility testing.

Performance testing

Performance testing plays an important role in non-functional testing. This type of testing is performed to approach product accessibility under the heavy load. This testing is carried out with an accurate testing procedure to determine the reliability, responsiveness, and stability of the software applications under different user loads.  

Usability testing

Usability can’t be ignored because it is a core test, this testing determines whether the software meets its intended purpose. Usability testing determines the software strength and weakness and examines the overall serviceability of the product.

Security testing

Business continuously faces cyber-attacks; the company is very concerned about their customer’s data and applications security. Company’s offer security testing to protect their applications from vulnerabilities and cyber threats.


 The above-mentioned software testing methods and types demonstrate the importance of testing in business and enterprise. The companies have software testers to debug the errors and deliver quality software to the customer. Make your business highly effective by enrolling software testers in your projects.
