It required maximizing the probability that minimum quality standards would be achieved by the production process. Quality assurance is an important factor in the software industry and any type of business. Software quality depends on customer satisfaction which can be achieved through the application of specific standards. Due to high customer demands, getting quality software is very important. Most of the developed countries are doing very well in the software industry and are improving day by day. Somehow even some developing countries are struggling with the quality of the software and fail to get a good reputation in the international market. Say no to plagiarism.

Most of the reasons are problems related to lack of interest and knowledge in improving software quality from higher authorities and software assurance team. Software testing is the execution of the software product with actual test data that produces the expected results. There are two types of fundamental concerns in software testing: which test cases should be used and how many test cases are needed? Software quality assurance is the set of activities that ensure that software processes and products conform to requirements and standards. Software testing in the field of software engineering is a process in the life cycle of a software project that verifies that the product or service meets quality expectations and validates that the software meets requirement specifications. Software testing is intended to find defects in a program, although a given testing method cannot guarantee to find all defects. Therefore, it is common for an application to undergo a variety of testing methodologies throughout the software lifecycle, such as unit testing during development, integration testing once modules and systems are completed, and customer acceptance testing. user to allow interested parties to determine whether their needs have been met. Introduction It is very important for any development industry to produce the highest quality products to achieve a respectable position in the global IT industry market. Competition is very high and you cannot afford to correct errors after delivering the products to the customer. A post-delivery fix is ​​very expensive and affects the credibility of the Company and organizations cannot afford to lose Customers due to these types of problems. To avoid these problems, organizations should follow a proper quality management plan to remove errors from products. Maintaining product quality is very important for business organizations as every business company is rushing towards automation. Failure of real-time software systems can have serious consequences. The main role of software quality assurance is to maintain the quality of software products. This is why you need to ensure that standards and procedures are properly followed. Software quality assurance standards are developed to helporganizations to obtain quality products. Standards are the set of guidelines that help achieve the best results. Sometimes, some critical issues have been found to degrade the quality of the software. He also suggested how the relationship between developers and the QA team can be more collaborative and how team leaders should react to some issues to resolve them. Software quality assurance plays a very important role in the affairs of a software company because the only factor that allows obtaining consistent projects from permanent customers is customer satisfaction. The main problems faced during real-time testing in any industry: • Time • Budget • Less use of quality standards • Lack of specialists • Duration of projects • Compromise on quality due to lower profits • Developer attitude • Team training for requirements gathering • PolicySome aspects can be resolved by providing good knowledge and motivation of the right management to carry out the work. Here it is necessary to understand the role of QA and QC for any software developer and software tester. It has been noticed in most cases that most people get confused when it comes to understanding the differences between quality assurance, quality control and testing. Although they are related to each other and up to a certain point, they can be considered as the same activities, but there are distinctive points that distinguish them. The following table lists the points that differentiate QA, QC and Testing. Quality Assurance Quality Control Testing QA includes activities that ensure the implementation of processes, procedures and standards in the context of verifying the developed software and its intended requirements. It includes activities that ensure the verification of a developed software against documented requirements (or not in some cases). It includes activities that ensure the identification of bugs/errors/defects in a software. It focuses on processes and procedures rather than conducting actual testing on the system. Focuses on actual testing by running the software with the goal of identifying bugs/defects through the implementation of procedures and processes.- Focuses on actual testing.- Process-oriented activities.- Product-oriented activities.- Product-oriented activities .- Preventive activities .- It is a corrective process.- It is a preventive process.- It is a subset of the software testing life cycle (STLC).- Quality control can be considered as the subset of quality assurance.- The testing is the subset of quality control. With the help of the above table it is easy to understand that a systematic process is explained very well to determine how the actual testing process is conducted within an organization or team. This is generally an independent examination of the processes involved during software testing. According to IEEE, this is a review of the documented processes that organizations implement and follow. Types of audits include legal compliance audit, internal audit and system audit. It is a formal technique that involves formal or informal technical reviews of any artifact identifying any errors or gaps. According to IEEE94, inspection is a formal evaluation technique in which software requirements, designs, or code are examined in detail by a person or group other than the author to detect defects, violations of development standards, and other problems. Formal inspection meetings may include the following processes: planning, overview preparation, inspection meeting, rework, and follow-up. During the life cycle of any software development is it necessary to continuously monitor that the direction of the product is correct? Which product will be developed,Right? At the same time, before delivering any product you need to match the original requirements, what will be delivered, right? To determine the progress of the process and the final product, it is very necessary to understand two terms for most people, who use them interchangeably. The following table highlights the differences between verification and validation. Verification Validation Verification answers the question: “Are you building it right?” Validation addresses the concern, “Are you building the right thing?” Ensures that the software system meets all functionality. Ensures that features meet expected behavior. Verification occurs first and includes checking documentation, code, etc. Validation occurs after verification and mainly involves checking the overall product. Made by developers. Made by testers. It has static tasks, as it includes collecting reviews, walkthroughs, and inspections to verify a software. It has dynamic activities, as it includes executing the software against the requirements. It is an objective process and no subjective decision should be necessary to verify a software. It is a subjective process and involves subjective decisions about how a software works. Software Testing Hierarchy Like almost all technical processes in the development of any software product, software testing has a prescribed order in which things should be done in a specific order and is ranked. Below is a list of software testing categories arranged in chronological order. These are the well-known and generalized steps taken to fully test new software in preparation for commercialization: - Unit testing: Testing performed on each module or block of code during development. Unit testing is normally performed by the programmer who writes the code.- Integration testing: Testing performed before, during and after the integration of a new module into the main software package. This involves testing each individual code module. A software can contain several modules which are often created by different programmers. It is crucial to test the effect of each module on the entire program model.- System testing: Testing performed by a professional test agent on the complete software product before it is introduced to the market.- Acceptance testing: Beta testing of the product performed by actual end users. Software Quality Assurance Software Quality Assurance (SQA) is the planned and systematic set of activities that ensures that software conforms to requirements, standards, and procedures. SQA includes the process of ensuring that standards and procedures are established and followed throughout the software acquisition lifecycle. Generally the development of any software product is a process of managing and dealing with numerous risks. These risks can be classified into two variables which are technical and programmatic; risks that the software will not work as expected or be too difficult to use, modify, or maintain are technical risks, while risks that the project will run over cost or schedule are programmatic risks. The goal of Software Assurance is to reduce many of these risks. Establishing standards and procedures for software development is critical. These provide the framework from which development and control processes are compared. Adequate documentation of standards and procedures is necessary because SQA process monitoring and product evaluation activities rely on unambiguous definitions to measure project compliance.
