Introduced in world war II, Quality Assurance is one of the most important aspects of a company because quality assurance gives the confidence to consumers to buy any product, it is also the foundation to any company’s growth.

Quality Assurance is essential not only for gaining customer confidence over the product but also to avoid problems from happening while delivering solutions or service. Quality assurance is majorly practiced in software development, medical  and multiple consultancy.

Quality Assurance is a systematic process and it goes through various phase let us see a few of them:

  1. Quality Assurance goes through a cycle called the Shewhart Cycle. The first stage of this cycle is plan, where all the planning is done to how the desired goal has to be achieved. Then comes into action, next is stage where the plan is incorporated. The production begins. The third stage is the check, where the product goes through various tests and verification. The last stage is the act, state where changes are implemented and necessary corrections are made to rectify the mistakes that are committed.
  2. Defining quality. The quality for the product is defined in such a way that it is ensured that the product meets the standard of a certain quality. Not only does the company need to define the standard but also make sure these standards are thoroughly understood by the employees of the company, otherwise quality assurance is compromised.
  3. After defining quality the next step to be taken is measuring it, measuring the quality is done by a higher supervision. A supervisor should always check the work of an employee and should make corrections when needed.When quality falls short, supervisors are responsible for bridging the gap.
  4. Improvisation leads to quality assurance only when there is improvement in the quality of the product. For example, If any application developer updates their software frequently to enhance the quality of the application software every product has to be tweaked in order to meet the requirements of the customer’s satisfaction and demand.
  5. Quality control is similar to Quality Assurance but not identical. Quality Assurance is the confidence given to the customer whereas quality control is the actual observation techniques used to check and control the entire quality process and to ensure that the quality assurance standards are met. Quality control are a set of procedures intended to ensure that a manufactured product adheres to a defined set of quality standards.
  6. Final step for quality assurance is the troubleshooting, every problem or every correction that is made is noted down, so it is useful in the future. Only quality assurance leads to higher growth of the company.
  7. The feedback step is very necessary step that every company takes to improve the quality of any service or product only after the feedback is received from the customer side does the company develops its services

Dynamic Testing and it’s Types in Quality Assurance

Most of us have an experience that the software did not work properly as expected and it impacts more on organisation. This article sheds light on dynamic testing and its various types.Let’s see an introduction about dynamic testing in QA.

Dynamic testing is also known as Dynamic Analysis, mainly used to test the software by executing it. This also checks for dynamic behaviour of the code. To compile and execute the software, variable quantities such as response time, memory usage, CPU usage, and overall performance of the software will be analysed.

This involves working with software, the various combination of input values are provided and checked with the expected output. In verification and validation, this testing type is the validation part.

Quality assurance work flow

Now let us see some of the dynamic testing methods in-detail:

1.Unit Testing

Unit testing is a process in software development in which small individual and independent parts of an application called units are tested. Units are the smallest testable part of the Software system. This verifies the smallest entity in any software.

A system should be tested individually before integrating it because once the system is integrated; it becomes difficult to differentiate the occurrence of an error in which unit. Hence unit testing is mandatory before integrating the units.

2. Integration Testing

In this method of testing, all the individual tested units are groups and the interface between the units are tested. This is mainly used to identify the problems in interface when two units are integrated. This is carried after unit testing.

The three main important approaches in integration testing are:

  • Top-down approach
  • Bottom-up approach
  • Big bang approach·         

3. System Testing

System testing is testing the behaviour of the whole system or software as defined in the Software Requirement Specification (SRS). This is primarily employed to verify the fulfilment of customer requirements. This testing method is carried after integration testing. This test method also checks for functional and non-functional software requirements.

Even though the system testing differs from organization to organization, the following key testing types which need to be covered in system testing are listed below:

  • Sanity Testing
  • Usability Testing
  • Stress Testing
  • Performance Testing
  • Regression Testing
  • Security Testing
  • Maintenance Testing
  • Accessibility Testing

4.Acceptance Testing

This type of testing is carried after system testing. During this type of testing most of the major bugs and defects have been fixed. Establishing confidence in delivering quality software or system that it meets the customer requirements is the main goal of Acceptance testing.

For Commercial Off the Shelf (COTS) software’s are meant for mass marketing needs by the potential users. There are two types of Acceptance testing namely:

  • Alpha testing is applicable for softwares that are developed for mass marketing. This is conducted at the developer site, potential users site or developers organization which invites to use the system and report defects.
  • Beta Testing is also known as field testing performed by existing users or customers at external sites with developers. This is used to determine that the software satisfies the customer requirements.

What is Software Development Lifecycle

SDLCThere are different programming advancement methodologies characterized and outlined which are utilized amid improvement procedure of programming, these methodologies are additionally alluded as “Programming Development Process Models” (e.g. Waterfall model, incremental model, V-model, iterative model, and so forth.). Every procedure model takes after a specific life cycle keeping in mind the end goal to guarantee accomplishment in procedure of programming improvement. Programming life cycle models depict periods of the product cycle and the request in which those stages are executed. Every stage produces deliverable needed by the following stage in the life cycle. There are taking after six stages in every Software advancement life cycle model:
