SOFTWARE TESTING

The difference between End to End test and system testing is:

CLICK TO READ THE FIRST PART:

1. 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.

2. End to end test: 

Here the actual workflow of a system is tested. Can a user navigate through the applications and does it work. It uses the exact production like data and the test environments to simulate the real time settings. It is also called as chain testing.

 

end to end testing

 

 

For example consider a situation where you login into your bank account and want to deposit some amount to another bank account which becomes third party subsystem. You follow the below steps

  1. Logging into the bank system
  2. Check the balance amount
  3. Deposit some money to  another bank from your account
  4. Check your latest balance
  5. Check out from your account

Following activities are done for testing build conditions like

  • Building a set of conditions for all the functions defined
  • The conditions which include data conditions, sequence and timing

End to End testing is a process of verifying the software system with its subsystems or parts. Here having the knowledge of whole system as well as interconnected subsystems is must.

  5. Q. What is End to End testing?
    End-to-end testing is a methodology used to test whether the flow of an application is performing as designed from start to finish. The purpose of carrying out end-to-end tests is to identify system dependencies and to ensure that the right information is passed between various system components and systems. Here, the 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.

    Q. What are the differences between system testing and End to End testing?
    System testing: You’re testing the whole system i.e. all of its components to ensure that each is functioning as intended. This is more from a functional side to check against requirements.

    End to end testing: This is more about the actual flow through a system in a more realistic end user scenario. Can a user navigate the application as expected and does it work. You’re testing the workflow.

    For EXAMPLE, if you were to test an e-commerce site the shop front:
    System test:
    Browsing for items, cart and checkout would all work fine.

    End to end test:
    You may then find issues with the workflow of moving between these areas of functionality.

    Q. Give some examples that prove that chain testing/End to End testing gives better performance for software product?

    – 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 subsystems 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.

  10. What is End to End testing?
    End-to-End Testing is a methodology used to test whether the flow of an application is performing as designed from start to finish. The purpose of carrying out end-to-end tests is to identify system dependencies and to ensure that the right information is passed between various system components and systems.

    What is the difference between system testing and End to End testing?
    The entire System is tested during System testing, meaning the functionality of all components are tested and validate. However, End to end testing check against requirements to make sure of actual flow through a system in a more realistic end user scenario.

    Give some examples that prove that chain testing gives better performance for software product?
    In reality it provides secure quality assurance for the software because performance testing eliminates bottlenecks. Most of all, Testers can identify weaknesses in the system and how they slow down overall functionality. For example, answering questions such as these prove that chain testing gives better performance for software product:
    o Is the application prone to crashes during extended periods of high user traffic?
    o Are there a lot of errors in one or a few functions?
    o Is the time needed to execute a request more or less than anticipated?

    Accessing the inbox
    Opening and closing the mailbox
    Composing, forwarding or replying to email
    Checking the sent items
    Logging out of the application

    System testing is a phase in the software testing cycle where a total and integrated application /system is tested.
    The focus of the system testing is to evaluate the compliance of the entire system with respect to the specified requirements. System testing helps in approving and checking the business, functional, technical, and any non-functional requirements of the application concerning the architecture as a whole.

    1. 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.
    2. End to end test:
    Here the actual workflow of a system is tested. Can a user navigate through the applications and does it work. It uses the exact production like data and the test environments to simulate the real time settings. It is also called as chain testing.

  15. END TO END 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.
    DIFFERENCE BETWEEN SYSTEM TESTING AND END TO END TESTING

    3. EXAMPLE: login functionality like login the application, checking the bank account by clicking on different options etc.

  16. 1.The process of verifying the software system with its subsystem is known as end-to-end testing.
    2.The difference between two is in System testing all the components of the system are functioning as expected in testing whole system whereas the actual workflow of the system is tested in end-to-end testing.
    3.Example:Transfering money from one bank to another bank account where another bank is subsystem.The steps are logging in your account, deposit money then transfer in another bank account is like a chain in software system.

  17. Q1 What is End to End 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 this 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.

    Q2.
    What are the difference between system testing and End to End testing?
    The difference between End to End test and system testing is:

    In End to end testing, the actual workflow of a system is tested. For example: can a user navigate through the applications and does it work. It uses the exact production like data and the test environments to simulate the real time settings. It is also called as chain testing.
    In System testing, functioning of the whole system and all the components of the system as per expectation is tested. For example in e-commerce website browsing items, cart and check out.

    Q3.
    Give some examples that prove that chain testing gives better performance for software product?
    End-to-end testing 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.

    1. Ensures Complete Correctness & Health of the Application
    In end-to-end testing, the application is tested and validated at all the layers – data layer, business layer, integration layer and presentation layer. This helps ensure complete correctness and health of the application.
    2. Increases Confidence in the Application
    End-to-end testing also increases the confidence in the functioning and performance of the application before its release as the application is tested across different endpoints for different devices and platforms comprehensively.
    3. Reduces Future Risks
    In end-to-end testing, the application is tested rigorously after every iteration and sprint. Thus, there are lesser chances of failure and risks in the future.
    4. Decreases Repetitive Efforts
    As the application is tested thoroughly, there is no looking back. End-to-end testing reduces the chances of frequent breakdowns and ultimately reduces the repetitive testing efforts.
    5. Reduces Costs & Time
    End-to-end testing via automation testing tool reduces errors recurrence, which means the application doesn’t require undergoing repeated testing. This considerably reduces the testing costs and time and helps achieve better productivity in other significant processes.
    End-to-end testing is a must to test and scale the application across a range of different systems, devices, layers, servers, database interactions, APIs and communication. Further, automating end-to-end testing allows you to quickly respond to changing business needs and adds greater agility to the entire testing project.

  22. 1. What is End to End testing?
    End to end testing is the testing of a software from beginning to end. It involves testing the components of software, its external and internal interfaces and interaction between different systems required for the complete functioning of the software. It can detect the defects which may affect the performance of the software. In other words, it is done to improve the quality of the software.
    2. What is the difference between system testing and End to End testing?
    System testing: Done before end to end testing. Involves testing only the different functionalities of software. Done to ensure the functionalities work as expected.
    End to end testing: Done after system testing. Involves testing of software, its interfaces and interaction between different servers and systems needed for maintaining the proper workflow of the software.
    3. Give some examples that prove that chain testing gives better performance for software product?
    In an online shopping software, the user can pick an item, purchase and pay for it and have it shipped all from the same website without having to worry about loss of data or breach of information or time consumption.

  23. 1)In End to End testing actual workflow will be tested. It uses the real time environment. Subsystems functionality also checked in End to end testing.
    2)All components of the system functions as expected in System testing. In end to end testing software checked in real time environment. actual workflow will be tested.
    3)Whenever software uses third party systems i.e sub systems within it we have to use end to end testing make sure all components are interconnected correctly.

  24. End to end testing is very important because it test the application end to end. This is done after the functionality testing ans system testing. It test the all functionalities in the software, their interfaces, external interfaces and interaction between system and the server like it in real time environment. It test the flow of the application and to make sure it works as we expect by interfacing the all the components in the system.
    System testing is to test whole system components to make sure it functions as we expected. The difference between the system and end to end testing is different functionalities tested in the system testing where as the work flow tested in end-to-end testing like it in the real time environment.
    Ex-For example consider a situation where you login into your bank account and want to deposit some amount to another bank account which becomes third party subsystem. You follow the below steps

    Logging into the bank system
    Check the balance amount
    Deposit some money to another bank from your account
    Check your latest balance
    Check out from your account

  25. 1. End to end testing is a process of verifying the software system with its sub systems or parts. The knowledge of whole system as well as interconnected subsystems is must.
    2.System testing whole software or application is tested at a time for the features or functionalities. But end to end testing is testing the software for its behavioral flow.
    System testing doesn’t need the knowledge of the application but end to end testing needs the knowledge of the application .
    3. Example of chain testing:
    Banking, online shopping etc.,

  26. 1.End to end testing is the major type of testing,in which it will be test the software 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 , it confirms that the integrated components of the software function as expected
    2. System testing- Testing the whole system & all components of the system is functioning as expected.
    End to End testing- Actual work flow of a system is tested and it is also called as chain testing
    3.Example for Chain testing is , lets consider a banking software or money payment software
    login to our account
    check available balance
    give the payment/transfer details and deposit/transfer
    check current balance
    Logout from the account

  27. End to End testing:
    End to end testing is a methodology used to test the performance of the application and to check its flow whether the application is performing as designed. End to end testing validates the software system and also checks the integration with external interfaces.
    Difference between system testing and End to End testing:
    In System Testing we test Testing the whole system and test whether all components of the system is functioning as expected.
    In 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.
    Some examples that prove that chain testing gives better performance for software product?
    Eg. Online purchase of an item using the Credit Card.
    In this Application the software system is interconnected with online payment system and third party site owned by other company, The risk of failing any one of the subsystem can be avoided by end to end testing, thus to save the entire system from collapsing. 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 gives better performance for the software product.

  28. End to End Testing is when – The entire application is tested in a real world environment like communicating with database, network, hardware and other applications.

    Difference between System and End to End Testing – In System Testing you check the application within itself (such as in online shopping, browsing, adding to cart, checking out). Whereas in End to End you test how the application behaves when interacting with other systems as well (such as in Banking, where the application may have to interact with systems of other banks)

    Chain Testing gives better performance because it tests the application’s response to other third party applications as well.

  29. System testing is done on the the functionality of the application. For example, online banking, checking balance, money transfer. End to end testing is done verify that the application is working as expected with the sub systems.
    Chain testing is done to deal with the complexity of software interactions with other subsystem. For example, clicking on ads displayed on social media platforms

  30. It is testing where the whole software is tested from start to end in an environment similar to real time in order to confirm that all the integrated components work as intended. It is done after the system testing, which is done in parts instead of all at once. End to end/chain testing has good performance because it simulates real time use, detects issues in subsystems, and checks integration with external interfaces.

  31. What is End to End testing?
    In This testing we have to check the software from beginning to end or we can say we have to check the each and every functionality of software.
    What are the difference between system testing and End to End testing?
    System testing – in system testing we have to follow the STLC process and also it is done by QA it has lot of type of testing like – smoke testing , functional testing , sanity testing ,regration testing
    End to End testing- In This testing we have to check the software from beginning to end or we can say we have to check the each and every functionality of software.
    Give some examples that prove that chain testing gives better performance for software product?
    Banking- money transfer from one bank to other bank .

  32. 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.
    Difference between system testing and End to End testing:
    System Testing: Testing the whole system to check all components of the system are functioning as expected. Example: any shopping website where all the all the shopping buttons, cart and checkout pages are checked (all the functionality).
    End to End Testing (or Chain Testing): The entire software is tested from end to end. The actual workflow of a system is tested. Example: any shopping website where all the shopping buttons, cart and checkout pages are checked (all the functionality) and integration with external interfaces like PayPal or credit card payment in payment page.
    Examples that prove that chain testing gives better performance for software product:
    Take the example of http://www.amazon.com website. Chain testing gives better performance of this website as all the functionality of the website (all the links, products) and integration with external interfaces (integration with different seller products, different payment interfaces etc.) are also tested. This gives a thorough testing and gives a better performance.

  33. 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.

    ome examples that prove that chain testing gives better performance for software product?
    Eg. Online purchase of an item using the Credit Card.
    In this Application the software system is interconnected with online payment system and third party site owned by other company, The risk of failing any one of the subsystem can be avoided by end to end testing, thus to save the entire system from collapsing. 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 gives better performance for the software product.

  34. 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 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.

    What are the difference between system testing and End to End testing?
    – In System testing the whole system and software will be tested to the expected. it will be done before end to end test.
    – In end to end testing the whole system, subsystems with software and hardware will be tested as how it suppose to work in real environment. It will be done after system testing

    For example consider a situation where you login into your bank account and want to deposit some amount to another bank account which becomes third party subsystem. You follow the below steps

    Logging into the bank system
    Check the balance amount
    Deposit some money to another bank from your account
    Check your latest balance
    Check out from your account
    The main reason is, it not only tests the he software system but also tests the sub-system too.

  35. – End to end testing is a major type of testing where all the applications in the software is tested from start to end. All the functionalities of the application, their interfaces, external interfaces ,interaction between different system and servers are tested in the environment similar to real time.

    -Testing all the components of the software and the requirements as expected are system testing.
    Testing the actual work flow of the system is end to end testing.

    -The software system is interconnected with many subsystems. Chain system tests all the subsystem of the application to ensure the better work flow and it provides reliability .
    for eg: To purchase through your amazon account you have to pay the bill using the bank account which is a subsystem here .
