Software Testing Objective and Goal
What is Software Testing
Software testing is a process of evaluating the quality of the software application to identify errors, gaps, or missing requirements. It is an activity where the actual result is compared with the expected result to ensure software meets the specific requirement. It mainly focusses on checks for functionality, specification, and performance of the application. It can be done either through manual processes or by using automated tools. In simple words, it can be described as the Verification of Application under test.
“Software testing is a process used to identify the correctness, completeness, and quality of the developed product. It includes a set of activities performed with the intent of finding errors in the product so that it could be corrected before the product is released to the end-users.”
Objective of Software Testing
Software testing is an important activity in the development of software applications. The major objective of software testing is the following. It is important because of the following reasons:
1. Early Defect Detection: If defects related to requirements or design are detected late in the life cycle, it becomes very expensive to fix them since it might require a redesign, re-implementation, and retesting. Thus organizations are looking towards the prevention of defects and early start of testing lifecycle activities to detect defects as an improvement area. This improves quality and productivity by preventing the introduction of defects later in the life cycle of the product.
2. Bug Prevention: The prevention of defects is done by performing a root cause analysis of the defects which was found previously and then taking specific measures to prevent the occurrence of those types of errors in the future. Efficient testing helps in providing a defect-less application. Thus this will result ultimately in reducing the overall defect count in the product, which further enhances the quality of the software.
3. Product Quality: Quality means “Fit for purpose” which can be referred to as meeting user requirements. The quality product delivered to the customer helps in building trust. Testing phase like device compatibility, performance, usability, adds a confidence factor to the stakeholders regarding the quality of the product. Another important factor to boost up the quality is that the product should need lower maintenance costs.
4. Security: This is the most sensitive and vulnerable part of software testing. It mostly caused due to an unexpected error in the design or coding of software. Users always look for trustworthy products with confidence that their personal information and data will be safe. Thus it is necessary that vulnerability risks in the software that could lead to misuse or exploit should be identified so that flaws in the design can be corrected.
5. Customer Satisfaction: Customer satisfaction is meeting every requirement. An ultimate goal for a product owner is to give the best customer satisfaction. It helps to gain trustworthy clients which will have great long-term effects.
6. Cost-Effective: The detection of defect at an earlier stage is cost-effective, that means it costs much less to fix them. The bugs identified at a later stage in the life cycle could lead to a change in design, code, test, release, etc. which ultimately becomes more expensive with cost and time. Thus tests start at an earlier stage is very important as it can save money in the long run.
Goal of Software Testing
The major goals of software testing are the following:
- Provide information in the form of reports to the project manager, project sponsor, customer, and other key stakeholders to help them make informed decisions about project status.
- Develop confidence in the product thereby helping stakeholders in making decisions.
- To determine that (software products) satisfy the BRS (Business Requirement Specification) and SRS (System Requirement Specifications).
- Finding the defects to understand the risks associated with putting the software into operational use.
- Gain the confidence of the customers by providing them a quality product.
- Finding defects at the early stages reduces the risk of Product Failure at a later stage.
- Evaluates product usability, performance, and reliability of software.
The parameters of the testing are defined based on the following:
- Functionalities that are most important to the project’s intended purpose.
- Functionalities most visible and used by the user.
- Aspects of the application which are most important for user
- Code complexity and areas that are more prone to error
- Highest-risks aspects of product
