What are the Types of QA Testing Services?

As mentioned earlier, software testing is crucial in the development process to identify and remove errors and bugs that can cause software failure. In addition, it analyses the functionality, usability testing, and performance of the software application according to the business needs and requirements.

The following are some of the significant types of software testing:

  • Black box testing: Black box testing enables the developers to test the application functionality without checking the internal working or source code. Besides, it separates the tester from the code creator, making the testing balanced. Here the tester assesses the software from the users' perspective to see if it aligns with the business needs and requirements. One of the benefits of implementing black-box testing is that it identifies vagueness and issues in the functional specification of the application.
  • White box testing: As opposed to black box testing, white box testing enables the tester to assess the internal working of the software application. Here the tester inspects the source code, its development route, and security. It facilitates the developers to achieve complete code coverage to eliminate unnecessary code or condense the existing code.
  • Functional testing: Functional testing assures the quality of the software by testing its functionality. It is a type of black-box testing that examines the application based on its specifications. Besides, functional testing involves different categories of testing, such as unit testing, integration, smoke, user acceptance, regression and sanity testing. As a result, it ensures security and improves software quality.
  • Performance testing: Performance testing or non-functional testing determines the performance, scalability, loading time, usability and endurance of the software. As a result, the tester can identify discrepancies in the software and improve its load capacity.

What are the Steps in Software Testing Process?

The software test process is a practice in the software development life cycle that involves a systematic approach to generate high-quality software for the end users. It identifies and eliminates the bugs and errors in the development to ensure high performance. Besides, testing can assess the software and its features to see if it meets the requirement and satisfies the users. Therefore, the testers in the software testing company follow the software test process to deliver the best solution.

Software Testing Process

The following are the crucial steps involved in the software test process:

  • Planning: The first step in the testing process is to develop an extensive test plan and strategy to implement effective testing for the software. Here the testers estimate the project focus and gather all the requirements and setup. Moreover, they determine the testing approach and evaluate the best solution needed for the project.
  • Test design: In this step, the testers create a test suite to verify and validate the developed software. In other words, they write and create test cases. They structure the tests to run, test data, and traceability matrices. Here, the ultimate goal of the tester is to make the test case understandable and achieve full coverage of the requirement.
  • Test Execution: This step involves the actual execution of testing according to the test plan and design. Besides, all the developers and testers work together to validate the executable code, and test scripts, and spot bugs and errors. During this stage, the team uses software testing tools and techniques such as unit testing, integration testing, performance testing, and user acceptance testing. In the end, the testers can document the results.
  • Reporting: The last step in the software test process is reporting. It is a continuous process that can be either oral or written. The reporting phase helps the developers to correct all the defects and concerns early at the lowest cost.
