Estimated read time 10 min read

Continuous Integration (CI) and Continuous Delivery / Deployment (CD) are sequential DevOps pipelines to automate the software development life cycle process. In most development phases, CI/CD automates the traditional manual process in mobile app testing

Various organizations prefer CI and CD for mobile applications or software development because CI/CD pipelines assist the development by automating the prolonged methods and allowing multiple developers to work on the different features of the same app. 

Appium is an open-source ecosystem and a tool for automating mobile app testing. Appium can automate on IOS, Android, and other mobile operating systems. Appium enables automated mobile app testing on multiple mobile OS simultaneously. Appium also supports multiple programming languages.

This article discusses the role of Appium in DevOps pipelines such as Continuous Integration (CI), Continuous Delivery, and Continuous Deployment (CD). Further, it will also let you know 20 functionalities that Appium performs with CI/CD. 

CI/CD Pipeline

Using Continuous Integration and Continuous Deployment pipeline in application development will produce high-quality code by eliminating the bugs during the development phases like building, testing, and deployment.

Continuous Integration (CI)

Typical mobile application development involves building a code base, testing the functionalities, and deploying. But Continuous Integration makes this so easy through automation. In an organization, if multiple developers are working on the same application but on different features, then the source program of the main branch/repository is branched into multiple branched repositories. Merging all those branch repositories simultaneously will raise conflicts among them. 

Continuous Integration (CI) integrates all the changes made to the source code after every merge. It automatically starts validating all the changes through different levels of testing, like unit testing and integration testing. This will ensure that the updated code changes are validated and do not affect the execution flow of the app. If an error occurs during the automated mobile app testing, Continuous Integration (CI) makes it easier to identify and resolve the conflicts. 

Continuous Delivery (CD)

After the merged branches were validated by the Continuous Integration (CI/CD), Continuous Delivery (CD) came into play and took over the final stage of the development. Continuous Delivery ensures that the updated main repository/Branch is packed well for production. It allows the user to access the new version of the application as soon as it is dispatched. 

The Mobile application on Continuous Delivery ensures it is ready for Continuous Deployment. At this point, the application is validated and error-free.

Continuous Deployment (CD)

Continuous Deployment is the final stage of the pipeline. Continuous Deployment is an automated deployment process. Developers can set the criteria for the time of the deployment beforehand. Continuous Integration (CI) can act as an independent practice, but Continuous Deployment depends entirely on the CI. 

Continuous Deployment is an add-on to Continuous Delivery. It boosts the application production through automation and helps the developer get user feedback and fix it immediately.

Difference between Continuous Delivery and Continuous Deployment

Continuous Delivery and Continuous Deployment are related but not similar, and they refer to different stages of application development. Both Continuous Deployment and Delivery improve the reliability and speed of the application. The main difference between these is in the final stage of the application, In continuous delivery, a manual decision is required. Meanwhile, in continuous deployment, the entire flow of execution is automated.

The Role of Appium in CI/CD

Appium is a free, open-source, automated mobile app testing tool. Appium has a client-server architecture, where the Appium server acts as an intermediate between the automation script and the mobile application.
