What is Continuous Development & Testing?
Continuous Development refers to the process where changes are added to the code, is deployed as & when changes are made & then delivered to the client on a regular basis. This is a part of the software development methodology which aims to enhance co-operation between development and operations teams in order to improve efficiency.
The most important step of this process is Continuous Integration where different members of the software development team add changes to the main code multiple times in a day. This way any bug or problem can be found out & rectified much easily which improves the quality of the output. The process is especially helpful when the team is large & working on different tools & platforms.
Once the changes to the code are made, it needs to be gets deployed into testing environments & if the code is deemed fit, then to production. When this is a fully automated process, it is called Continuous Deployment. This is followed by those who have strong process & development team that reduces the risk that arises from automated deployment. When the software delivery is done manually, it is known as Continuous Delivery.
In both processes the purpose is to ensure that the code should be ready to be deployed to production. As a result, the objective is to help the software development team to focus on coding. The only difference between them is the method of deployment to the production server.
After it has been established that the code is indeed ready to get deployed to production, the next step is to show that it actually works through testing. Continuous Testing helps minimize business risk, provides immediate feedback to the software development team & improve efficiency. This helps to eliminate problems along with improving the final software. In order for this process to be more beneficial, testing should begin as soon as is possible & must be done frequently.
The purpose behind implementation of Continuous Development & Testing is to ensure quicker turnaround, streamline the process & improve product quality. It is crucial to integrate the different processes into a seamless & effective software development cycle to be able to get the most benefit of each & improve overall efficiency.
