Continuous Delivery: The Ultimate Boundary of Continuous Testing
November 5, 2019
Continuous Integration (CI) and Continuous Delivery (CD) development team push the code change into a common repository ensuring that it does not impact the changes made by developers working parallelly. The main aim of CI/CD is to reduce the possibilities of flaws and conflicts during the integration of the project.
What is Continuous Integration?
CI is a practice in which developers integrate their code in a common repository frequently. Instead of integrating the entire code at the end of the development cycle, the code is shared with the repository multiple times in a day.
Benefits of Continuous Integration
- Automated Processes:
CI automates stability, build many other tests while ensuring a path for successful continuous delivery.
- Increased transparency:
Transparency is maintained throughout the development process. This gives the team members idea of when the test fails, for what reason and detects further bugs.
- Reduced Bug Count:
In the software development lifecycle, bugs occur very often, but with the use of CI and CD, the bug count is reduced. So, errors are detected easily and are resolved at an early stage.
- Early Bug Detection:
Implementing CI/CD helps in detecting bugs at the early stage so developers can fix that bug before proceeding further. It also helps the QA team as they have to work on stable and bug-free builds.
- Cost Optimized Process:
With reduced bug count, manual testing time is reduced, and the team has clarity of the overall system. This reduces the overall cost of the project.
What is Continuous Delivery?
Continuous Delivery is an extension to Continuous Integration. The main aim of the CD is automating the software delivery cycle; this will help team members to easily deploy the code at any time. Using the CI/CD, team becomes confident in releasing the software without last-stage testing. To be effective, CD requires both organizational and technical improvements.
Benefits of Continuous Delivery
- High-Quality Software
By implementing CD, most of the processes are automated. So, now testers have enough time to concentrate on important tasks such as usability, exploratory, performance and security testing. This ensures the quality of the product.
- Risk Reduction
The focus of the CD is making the deployment faster and easier. Blue/Green pattern mitigates the deployment risks with almost no downtime.
- Cost Optimization
The cost of frequent bug fixing and improvement are reduced as costs associated with the release of the software are eliminated with the implementation of CD.
- Better Product Quality
CD focuses on painless product release. With a continuous release cycle, the team works with the users and can understand their needs thoroughly as this will help team members to learn new ideas to work for quality output.

Steps for Implementing Continuous Integration and Continuous Delivery
- Multiple developers are involved in a large project for constantly pushing and pulling the code to build an application. A revision control system is required for the team to get the latest code from the repository at any point of time during SDLC.
- Automation ensures that the team receives the latest code as it must be compiled before the build of the final product. The automation cycle allows developers to push the code in different environments, this makes the release easy and faster.
- Including automation unit testing will help the team to detect the bugs at the initial stage of the cycle before the code is pushed in the repository. The state of the product is known in unit testing and this makes the testing phase easier with speedy bug fixing.
- Because of a different environment, often the application testing scenarios fail in production. To avoid such circumstances, testing should be done in an environment that is similar to the production environment. This will help testers to understand how the application performs before it is deployed.
- Developers should follow the practice of committing the code regularly in the repository to prevent conflicts. It improves the communication between the team members and leaves a small room for errors. This allows developers to keep track of their work.
- The main purpose of CI is to get instant feedback after the build. If the build is quick and perfect, then a high-quality output with minimal errors can be expected.
Continuous Integration and Continuous Delivery leverage thorough automation and stimulate constant code sharing to fix defects early. While the techniques, processes, and tools needed to implement these solutions represent a significant challenge, the benefits of a well-designed and properly used system can be gigantic.
