Friday April 26, 2019

Quality Assurance (QA) is something other than manual testing. The current frameworks are more unpredictable than customary methodologies can deal with. New automated test methods have developed enabling machines to automatically and thoroughly test themselves for flaws.

With this article, we are going to give you in-depth knowledge about Quality Assurance.

What is Quality Assurance?

Quality Assurance (QA) or Software Quality Assurance (SQA) is a planned and systematic model of activities essential to give satisfactory assurance that a product adjusts to prerequisites amid software improvement.

SQA incorporates the complete software development life cycle, and the purpose is to make sure that the development and support processes are refined continuously to generate products which satisfy specs.

Remember that the range of quality isn’t restricted to merely Software Testing. For instance, how adequately the requirements are asserted and also maintained quite matter.

Software Quality Assurance comprises of strategies and practices of evaluating the software development methods, processes, technologies, and tools used to guarantee the quality of the created product. It is typically accomplished by using well-planned standard systems, covering processes and tools, for quality control to assure the reliability and dependability of the product.

The Quality Assurance process can involve –

  • Recognizing standards when any applied in software development methods.
  • To carry traditional processes, for example, quality reviews.
  • Conduct in-process test data recording processes.
  • Encouraging documentation procedure measures.

This extraordinary issue fills in as a platform for experts to display hypothesis, results, understanding, and different progressions in Software Quality Assurance process.

Process of Quality Assurance

 

Below are a few quality characteristics of the Quality Assurance process –

  1. Concentrate on the User Experience

Testing at all stages of the venture is critical. However, the most dominant point is the user experience.

In case that the UX is terrible, it unavoidably implies the quality isn’t of standard. Despite the fact that this will presumably result in variations in the earlier stage of software development, the user experience should dependably be at the leading place.

  1. Automation and Continuous Integration

Automation is essential since it offers quick review, empowering continuous integration – an important part of the agile approach.

Automation is additionally solution to lessening costs and improving the productivity of your QA staff; that is one of the principle reasons why QA engineers must teach themselves and be apt to execute automation processes.

  1. Test and Code Coverage

Numerous QA managers ramble about “test coverage,” that gives a decent broad image of the quality of the product. But to accomplish genuine quality, test cases and code coverage examination both ought to be held.

For instance, regardless of the fact that 100% test coverage is performed by you, you have to, in any case, go for a minimum 90% function code coverage to guarantee the best outcomes.

  1. The Shift-Left Approach

Software testing begins commonly once the coding stage is finished. In any case, for ideal quality in an agile strategy, you have to drive the concentration and start checking as well as testing directly from the origin of the venture. It guarantees bugs are identified sooner, that saves both money and time.

Additionally, it ensures a positive association with developers in the group, quickens the delivery of the application, and takes into consideration more noteworthy test coverage.

  1. Smart Testing

Full and thorough testing can now and again lead to a challenge since numerous personals might not have resources or time to experience each reasonable combination of cases.

But you ought to be smart in how and what to test. It implies, speaking with the engineer to discover little experiments that will identify the best number of bugs.

  1. Bug Prevention

QA managers are prepared to detect bugs, but an ingenious QA specialist will likewise consider how to avoid them in any case.

Conventional QA begins testing at the UI level, yet an agile process begins with the functional and unit testing and after that moves to the UI phase. This methodology keeps bugs from entering the top level of development which can later on lead to more severe issues and likely postpone the delivery.

Furthermore, concentrate on major crucial bugs and errors at first as opposed to many small errors.

  1. Portability

It is critical for software to adjust to various environments. For example, a framework should operate just as efficiently on a web platform as it works on mobile.

The versatility, installability, replaceability, and conformance of the product should be recorded respectively.

  1. Reliability

A system crash is not a unique situation. However, in quality testing, you require to check the system’s capacity to resist component breakdown. The system ought to be ready to get back into complete control even after a possible malfunction in the product.

  1. Documentation

This process manages the administration and archiving of documents. Any variation in a record is done by using the appropriate change control method. Approval of all kinds of documents is also done in this process.

Methods Used in Quality Assurance

 

There are a few distinct kinds of QA testing, which are all critical for guaranteeing your application is having no bug. Beneath, we’ve given the most vital QA testing methods to offer you a full comprehension of the testing procedure and how it improves your application, product, or software.

Non-functional Testing

QA testing can be separated into two sections: functional and non-functional testing. Before we discuss the functional testing, how about we take a look at the four phases of non-functional testing –

  • Vulnerability Testing

Vulnerability testing includes testing a site or application to find security holes and vulnerabilities that could be exploited by hackers. The objective of this phase of testing is to make sure that there are no security risks that could compromise users’ information or other sensitive data.

  • Compatibility Testing

Similarity testing includes checking that product is completely compatible with the software and hardware it will be running on.

A few components are tested amid this stage, from internet browsers to hardware, operating systems, integral modules, and that’s only the tip of the iceberg.

  • Usability Testing

Convenience testing includes testing that the software is intuitive and easy to use. The objective of this phase of the testing process is to ensure that the end user can utilize the product without dissatisfaction or confusion because of its design and UI.

  • Performance Testing

Performance testing includes confirmation that the product performs adequately in an assortment of conditions that could influence users, from substantial load to insufficient battery power.

The goal of a performance test is to make sure the application runs as it ought to and to determine its confinement utilizing load testing.

Functional Testing

Functional testing is generally separated into four segments. Every one of them is depicted beneath –

  • Unit Testing

The Unit testing method is the testing of individual software modules or parts that make up a system or an application.

The module’s developers normally write these tests and in a test-driven-improvement strategy, (for example, Agile, XP, or Scrum).They are written before the module is made as a component of the spec. Every module function is tested by a particular unit test installation written in a similar programming language like the module.

  • Integration Testing

This part of the testing process includes the testing of the distinctive modules or components that have been effectively unit tested when incorporated together to perform particular activities and tasks (otherwise called scenario testing).

This testing is typically finished with a combination of manual testing and automated functional tests relying upon the fact that it is easy to make automated tests for particular integrated components.

  • System Testing

System testing expands the scale of integration testing to test the whole framework all in all. A standard system test includes running the whole framework so as to find beforehand neglected bugs, stability problems, and serious issues.

As should be obvious, the initial three phases of functional testing include a steady increment in range, from a sole unit to many integrated units to a whole system.

  • Acceptance Testing

The acceptance testing technique is the last stage of functional software testing and includes ensuring that all the project or product necessities have been met. It also assures that the customers and end-users have tested the framework to ensure it works as assumed and meets all their defined prerequisites.

Conclusion

Software Quality Assurance covers the entire process of development cycle to make sure that a product has met its specification in the top most quality possible.

Quality assurance identifies weakness and issues related to the process and will make sure that nothing like that surfaces. It works on continually improving the process of producing a better product. Capability Maturity Model Integration (CMMI) and ISO 9000 are widely used systems when it comes to Quality management.
