How does a QA do performance testing of an application?

The complex process of determining whether a product meets specific requirements and expectations is known as quality assurance (QA). It aids developers in setting objectives and defining quality standards.

QA is also in charge of identifying and correcting flaws and deficiencies before the product is released to the public.

Quality Assurance (QA) or Software Quality Assurance (SQA) is a planned and systematic set of activities required to provide satisfactory assurance that a product meets requirements during custom software development services.

SQA encompasses the entire software development life cycle, intending to continually refine development and support processes to produce products that meet specifications.

The Quality Assurance process may include the following steps:

  • To carry out traditional processes, such as quality reviews.
  • Identifying standards when they are used in software development methods.
  • Carry out in-process data recording processes for test data.
  • Encouragement of procedure documentation measures.

Characteristics of the Quality Assurance process


It is critical for software to be able to adapt to different environments. A framework, for example, should work just as well on a web platform as it does on a mobile platform.

The replaceability, versatility, installability, and conformity of the product should all be documented.

Pay attention to the User Experience.

Testing is essential at all stages of the venture. The most important aspect, however, is the user experience.

If the user experience is poor, it is unavoidable that the quality is poor. Even though this is likely to result in variations in the early stages of software development, the user experience should always take precedence.


A system crash is not an unusual occurrence. However, you must examine the system’s ability to withstand component breakdown. Even if the product malfunctions, the system should be prepared to regain complete control.

Coverage of Tests and Code

Many QA managers talk about “test coverage,” which provides a good overall picture of the product’s quality. However, to achieve genuine quality, both test cases and code coverage examinations must be performed.

Bug Elimination

This methodology prevents bugs from reaching the top level of development, where they can cause more serious problems and likely delay delivery.

Methods used in Quality Assurance

There are several types of QA automation web testing, all of which are essential for ensuring that your application is bug-free. There are two types of QA testing: functional and non-functional testing.

1 Non Functional Testing

Non-functional testing is further subdivided into the methods listed below:

Vulnerability Testing

Vulnerability testing entails examining a website or application for security flaws and vulnerabilities that hackers could exploit. This phase of testing aims to ensure that there are no security risks that could compromise the information of users or other sensitive data.


Performance Testing

Performance testing requires confirming that the product works adequately in a variety of conditions that may affect users, ranging from heavy load to insufficient battery power.

A performance test’s goal is to ensure that the application runs as it should and to determine its limit using load testing.

Usability Testing

Convenience testing entails ensuring that the software is simple to use. This phase of the testing strategy aims to make sure that the end-user can use the product without being dissatisfied or confused by its design and UI.

2. Functional Testing

Functional testing is generally separated into four segments. They are listed below-

Unit Testing

The unit testing method is used to test individual software modules or parts of a system or application. The module’s developers typically write these tests and in a test-driven-improvement strategy (for example, Agile, XP, or Scrum). They are written before the module is created as a spec component. Every module function is tested by a specific unit test installation written in a programming language similar to the module.

Integration Testing

This stage of the testing process entails testing the various modules or components that have been successfully unit tested when combined to perform specific activities and tasks, which are otherwise also called scenario testing.

This testing is typically completed with a combination of manual processes of testing and automated functional tests, owing to the ease with which automated tests for specific integrated components can be created.

System Testing

System testing extends the scope of integration testing to test the entire framework. A standard system test entails running the entire framework to detect previously overlooked defects, stability difficulties, and major concerns.

The first three phases of functional testing, as should be evident, entail a constant increase in range, from a single unit to several integrated units to a comprehensive system.

Acceptance Testing

Acceptance testing is the final level of functional software testing and comprises checking that all project or product requirements have been met. It also ensures that the framework has been tested by customers and end-users to guarantee that it operates as expected and satisfies all of their set requirements.


Quality assurance finds flaws and issues with the process and ensures that they do not reoccur. It is constantly working to improve the process of producing a better product. When it comes to quality management, Capability Maturity Model Integration (CMMI) and ISO 9000 are extensively utilized systems.
