Types of End-to-End Testing

There are two types of End-to-End testing – vertical and horizontal.  While horizontal end-to-end testing is most commonly associated with this testing method, it’s crucial to realize that both play a part in building a successful end-to-end strategy.

The process of horizontal end-to-end testing is used to verify that every workflow or transaction in an application occurs correctly. Historically, this may have occurred in a single application or interface, but software systems today interact with a myriad of external interfaces, both those developed internally and those owned by third parties. With horizontal end-to-end testing, it’s essential your test environments are set up in advance to ensure a smooth testing process.

Vertical end-to-end testing entails thoroughly testing each sub system, independent from one another, starting the bottom layer and working your way up through each series of connected pieces – from back to front-end.

End to  End testing:It is a technique used to test whether the flow of an application right from Start to finish is behaving as expected.The purpose of performing end to end testing is to identify system dependencies and to ensure that the data integrity is maintained between Various system components and systems.The entire application is tested for critical functionalities such as communicating with the other systems,interfaces,database,network and other applications.

End to End Testing methods:

1.Horizontal End To End Testing:This method is used very commonly.It occurs horizontally across the context of multiple applications.This method can easily occuring in single ERP(enterprise resource planning) application.Take an example of web based application of an online ordering system.The whole process will include accounts,inventory status of the products as well as shipping details.

2.Vertical End to End Testing:In this method all the transactions of any application are verified and evaluated right from the start to finish.Each individual layer of the application us tested starting from top to bottom.Take an example of a web based application that uses HTML codes for reaching web servers.In such cases,API is required to generate SQL codes against the database.All these complex computing scenarios will require proper validation and dedicated testing.Thus this method is difficult.

White box testing and black box testing both are associated with an end to end testing or in other words we can say that this is the combination of benefits of both white box testing and black box testing.Depending on the type of software being developed at different levels both the testing techniques are requy.Basically the end to end performs functional as well as the architectural approach for any software or programs to validate system functions.

End-to-end testing is a Software testing methodology to test an application flow from start to end.  

Horizontal End to End testing:  

It occurs horizontally across the context of multiple applications. This method can easily occur in single ERP application.  

Vertical End to End testing:  

In this method, all the transactions of any application are verified and evaluated right from the start to finish.
