How Continuous Integration has Changed Modern Application Development

Continuous Integration or CI is known as the foundation of modern software development’s foundation. Let’s take a look at how continuous integration has changed the whole concept by solving different problems. 

But before that, let’s take a look at the scenarios presented before continuous integration in the traditional development model.

  • At the initial stage of the project; it is segregated into modules and each module is assigned to the corresponding developer
  • Then an individual module is been developed by the developers for unit testing
  • After the completion of the module development; the project manager integrates all the codes.
  • The project manager deploys the integrated project for server testing and then submits it for integration testing
  • The testing process brings up the bugs 
  • Then the project manager assigned the allotted responsible person to debug
  • After the modification, the project manager again integrates the project and then deploy it to the test server
  • The integration testing process is executed by the tester
  • After checking and ensuring; the product is deployed to the production environment

In case, it does not pass the test; then the whole above process will be repeated

Problems Face In the Traditional Process:

  • Testers usually find out the bug at the end. 
  • It is difficult to find out the root cause of the bug and as the result, the developers must spend their time in the integration phase resulting in higher development costs.
  • There is no guarantee of the software delivery time as they cannot fix the bugs in time
  • For Agile developers; the projects required to be changed
  • User satisfaction is very low in this module

How Continuous Integration has Changed Modern Application Development?

While we found that some of the work in the traditional process is unavoidable; there is still room for optimizations. And continuous integration is the master plan to solve all the problems. 

In this process, all the developer working copies are merged into the trunk, multiple times a day. According to the requirement of the project, it is integrated as there is no set frequency of it. 

In this process, any code change is directly reflected in the database. 

As a result, it quickens the whole process with higher product quality. The current state of the product is visible to every member of the team. In this way, continuous integration has changed the whole concept of modern application development.
