END TO END TESTING

SOFTWARE TESTING

End to end testing is a major type of testing where entire software is tested from start to end. All the functionalities within the software, their interfaces, external interfaces, interaction between the different servers & systems are tested in the environment similar to real time.

End to end testing confirms that the integrated components of the software function as expected. The entire application is tested in a real world environment like communicating with database, network, hardware and other applications. End to end testing methodology is used to test the performance of the application and whether the flow of an application is performing as designed. Generally end to end testing is phase of software testing which not only validates the software system but also checks the integration with external interfaces. The purpose of software testing is to exercise a complete production like environment. Along with software system it also checks the batch or data processing through other upstream or downstream systems. End to end testing is done usually after functional and system testing.

Why we need end to end testing?

The modern software systems are complex and are interconnected with each other. The part of a system or the subsystem may be different in functioning from the current system or may be owned by other company. If any one of the subsystem fails then the whole system may collapse. This major risk can be avoided by this end to end testing process. It verifies the complete system resource flow. It increases the test coverage of various subsystems. It helps to detect with various issues of subsystems and increase the confidence of any software application.

The chief activities involved in end to end testing are

  • The study of end to end requirements
  • Test environment is set up with hardware and software requirements
  • The systems and subsystems processes is described
  • Roles and responsibilities of all the systems are explained.
  • Testing  the methodology and its standards
  • End to end requirement tracking
  • Input and output data of each system

  1. 1.End to end testing is a testing which performed from start to end process. End to end testing is phase of software testing which not only validates the software system but also checks the integration with external interfaces. In End to end testing all the functionalities within the software, their interfaces, external interfaces, interaction between the different servers & systems are tested in the environment similar to real time.

  2. 1. What is End to End testing?
    End to End testing is a process of verifying the software system with its subsystems or parts.
    2. What are the difference between system testing and End to End testing?
    Systems testing the whole system all components of the system is functioning as expected while end to end testing testes the actual workflow of a systems, from start to end.

    3. Give some examples that prove that chain testing gives better performance for software product?
    Chain testing checks all aspects of the systems, including other upstream or downstream systems. It increases the test coverage of various subsystems. It helps to detect with various issues of subsystems and increase the confidence of any software application. If any one of the subsystem fails then the whole system may collapse. This major risk can be avoided by end-to-end testing process providing better performance.

  3. End to end testing is a major type of testing where entire software is tested from start to end. All the functionalities within the software, their interfaces, external interfaces, interaction between the different servers & systems are tested in the environment similar to real time.
    End to end testing verifies the complete system resource flow. It increases the test coverage of various subsystems. It helps to detect with various issues of subsystems and increase the confidence of any software application.

  4. 1. End to End testing:
    End to End testing is a process where entire software is tested from start to end in order to verifying the software system with its subsystems or parts.
    All the functionalities within the software, their interfaces, external interfaces,
    interaction between the different servers & systems are tested in the environment similar to real time.
    2. Difference between System testing and End to End testing:
    System Testing:
    -System testing is performed to check the features and functionalities of the system are as expected and checks the compliance of the system with requirements of client.
    End to End Testing:
    – End to End Testing is performed to check the complete flow of the system.It uses the exact production like data and the test environments to simulate the real time settings. It is also called as chain testing.
    3. Examples to prove that chain testing gives better performance for software product :
    The purpose of Chain testing is to test the complete flow fo the system. Along with software system it also checks the data processing through other sub systems.
    The part of a system or the subsystem may be different in functioning from the current system. If any one of the subsystem fails then the whole system may collapse. This major risk can be avoided by the Chain testing process. It helps to detect with various issues of subsystems and increase the confidence of any software application.
    Eg: 1) Sending files Through one application to another application.
    2) Sending money from one account to another through money transfer applications
    3) Booking connecting flights through different airlines.

  5. 1. End to End Testing :
    End to End testing is a process of verifying the software system with its subsystems or parts. All the functionalities within the
    software, their interfaces, external interfaces, interaction between the different servers & systems are tested in the environment
    similar to real time.
    2. Differences between System and End to End Testing :
    System Testing – Testing the whole system all components of the system is functioning as expected. For example in e-
    commerce website browsing items, cart and check out.
    End to End Testing – the actual workflow of a system is tested. It uses the exact production like data and the test
    environments to simulate the real time settings. It is also called as chain testing.
    3.Examples : Online Purchase with different types of payment metods such as Credit card ,Paypal …
