Introduction to Continuous Integration & Delivery (CI/CD)

CICD Introduction


Continuous Integration (CI) is an improvement practice that expects engineers to incorporate code into a mutual vault as and when done. Each registration is then confirmed by a automated assembly, enabling teams to identify issues early, if any.

Continuous Delivery (CD) is the common expansion of Continuous Integration, an approach in which groups guarantee that each change to the framework is releasable and that you can discharge any rendition at the push of a button. Continuous Delivery intends to make releases exhausting, so you can convey much of the time and get quick input on what clients think about.


There are some basic necessities to consider before adopting CI/CD Models. The process sounds simple but you might run into challenges if you do not implement the right one at the right time. Below are some of the tips when we can adopt CI/CD Model in our projects.

1. Confidence in Automation:

CI/CD aims to replace most of the repetitive and manual work by automation. You need to have full confidence on your automation processes not only in terms of your test coverage but also the processes that are involved throughout the integration and delivery of quality product as quickly to the customers as possible.

2. Team Skill-Set:

It is very essential to have a team with a mindset of automating processes in order to implement CI/CD. Any gaps can create inefficiency. Yes, it takes time and effort for a team to learn the complementary skill-set to support one another but it definitely is one of the important aspects.

3. Selection of Tool:

There are various questions the team need to ask and get answer for before deciding any tool to implement CI/CD. What kind of notification setup you need at various stages of the pipeline? What kind of approval processes you want at different gates? These are only couple of examples of questions. You need to invest more time analyzing the need and selecting the best tool that fits your project.


Below are some of the important pros of implementing CI/CD.

1. Automated Tests run whenever the code is committed and integrated. This helps in identifying the issues early so can be resolved early.

2. The code changes are committed in smaller units so it is easy to rollback changes if any larger issues occur.

3. You can do a release at any time and delight customers with faster delivery with high confidence in quality product.


Automated, robotized, computerized test are some key terms you can hear as essential piece of any CI/CD pipeline. No matter what type of automated test suite you have, below are some essential types of tests you need to maintain to gain high level of confidence on your test as part of the CICD. The rundown underneath gives a little review.

1. Unit Tests:

This is the suite that is run in the first place, frequently by designers themselves before they add their progressions to the vault. Unit tests typically test singular classes or capacities. These play vital role in finding any issues at the earliest in the process.

2. Integration Tests:

These are the level up tests from unit tests which are coordination tests and ensure that the modules that contain an application work legitimately with each other. This test ensures that the modules are working as a complete whole rather than just working in isolation.

3. System Tests:

System tests ensure that the entire framework in a domain is working as expected. This test is integral part of the CI/CD process to ship a quality product to customers.


The fundamental objective of utilizing Continuous Integration and Continuous Delivery (CI/CD) is to make sure that team is capable to implement an automated process to ship smaller units in a form of enhancements to customers as quickly as possible and with the best of quality. Also, it helps the team to take quick actions if any issues occur during or after delivery. Overall, a great concept to delight customers, if implemented in a correct way.

  1. 858372 848528Aw, this was a really nice post. In thought I would like to place in writing in this way moreover – taking time and actual effort to create a very good article but what / things I say I procrastinate alot and also no indicates apparently get something done. 319348
