Fundamentals of Testing

In Software Development Life Cycle, delivering the right product to stakeholders is impossible without Software Testing. Software Testing reduces problematic delivery by testing the software using appropriate test techniques and expertise at different test levels. Let's see a few examples of how Testing can contribute to project success:

1. Requirement Review: We can save a lot of cost by involving the tester early stage of SDLC to review the requirements or user stories. Identifying and removing requirement defects reduce the risk of the wrongly delivered product. Project Knowledge gained by the tester at this stage will help them in test design and execution.
2. System Design Understanding: If the tester works closely with the system designer while the system is being designed, it will increase each party's understanding of the design and give testers an idea of how to test it better. Testers' understanding can reduce the risk of design defects and enable them to do system or integration testing easily.
3. Code Implementation Knowledge: Having testers work closely with developers gives them the idea of what needs to be tested for a particular story and the impacted areas. Basic code implementation knowledge allows testers to test APIs, Databases, and other system components quickly. Also, checking APIs and logs before reporting bugs saves time for creating duplicate bugs.
   
   For example, there is no need to create unnecessary bugs for Web, Android, or iOS applications when the issue is in an API common to all. Testers can redirect bugs to the right team by doing basic debugging from their end. For example, environment bugs need to be sent to the DevOps team.
4. Verification and Validation: Verifying and validating before releasing the software reduce failures. With this, Testers can support debugging and increase the likelihood of meeting stakeholders and customer expectations.
