End to End testing vs Integration testing

Many people in the world of software testing tend to be confused by the terms end-to-end and integration testing. We searched the internet and discovered a wide range of viewpoints, so we decided to contrast the two, give some context, and produce an authoritative reference. these tests aim to examine the connection and communication between various application components. It is useful to understand how each approach works in order to properly grasp End-to-End testing Vs Integration testing. But first, what exactly do End-to-End testing and integration testingIn this article, learn how to differentiate between end-to-end testing vs integration testing. Find out how these increase your test coverage. 

What is End-to-End Testing?

End-to-End testing ensures that your software functions properly from the start to the finish of a certain user flow. It simulates typical user behavior and different usage to make sure your program functions as a whole. End-to-End testing incorporates the integration your program has with external applications as well as a production equivalent environment and data to emulate real-world conditions. 

What is Integration Testing?

The connection and interfaces between the various components are also looked at, and the software modules are tested together. The operations at the project level for integrating the individual constituent must be coordinated. For the defined integration of early bug detection, the integration, and integration must follow a building plan. |But unlike a system tester, an integration tester needs to know to program. 

End-to-End testing Vs Integration testing | Difference between end-to-end testing and integration testing:

  • When the product is almost ready for release, end-to-end testing is carried out. While the integration testing starts at the very early stages of development. Bugs are caught earlier, rather than later, in the cycle. 
  • End-to-End testing may be impossible to perform until the product is nearing completion. Integration testing is easy to integrate with daily builds and easy to test in the development environment. 
  • End-to-End tests run slower compared to integration testing While the integration test runs faster compared to end-to-end tests. 
  • End-to-End testing of the product as the user would experience it. While the integration testing to make sure app components work well together.
  • End-to-End testing aims to test the user experience from start to finish. While the integration testing aims to test how external systems work with internal modules, one by one. 
  • End-to-End testing can be used for either a single process being executed from start to finish or various different processes involving different applications. Integration testing is used to test a single process from third-party software that will be used in conjunction with your software. 
  • End-to-End testing scope is wider and spans the entire application technology stack. Integration testing the scope could span multiple components but won't span the entire stack most of the time. 
  • End-to-End testing is higher level than integration testing. While the integration testing is higher level than unit testing. 
  • End-to-End testing is more expensive to implement. Both in terms of hardware and software. While integration testing is less expensive to implement.
  • End-to-End testing is done to have a feel of the user experience of the app. Integration testing is done to discover connectivity issues between components when they are working together.
