hmmm… Seems like we need to provide a Corporate e-mail address ( gmail or hotmail ect. not allowed) to read this article.

Or am I approaching this article incorrectly? :thinking:

  1. to combine units as groups
  2. it will expose problems between interfaces before releasing the application.
  3. top down is the obvious opposite of bottom up. Its checking the highest level module first and digs deeper from there. Bottom up testing should be done first though.

  1. Software testing in which individual software modules are combined and tested.

  2. Helps to identify issues with interaction of Modules which works alone.

  3. It means testing each part first and then a combination of it, top-down is the other way around.

Reading Assignment: Integration Testing

  1. Why do we write integration tests?
    To test combined program units as group in multiple ways.

  2. What problems do integration tests solve?
    Integration testing can expose problems with the interfaces among program components before trouble occurs in real-world program execution.

  3. What are the differences between top-down and bottom-down approaches?

  • Bottom-up integration testing begins with unit testing, followed by tests of of progressively higher-level combinations of units called modules or builds.
  • Top-down integration testing, the highest-level modules are tested first and progressively lower-level modules are tested after that.

These test software modules as a group. Different programmers code different modules, and the purpose is it expose any defects in code interaction when the modules are integrated. It focuses on checking data communication amongst these modules.

Bottom-up = unit testing, then testing progressively larger combinations of units (modules/builds)
Top-down = integrated modules are tested first and progressively test smaller units.

1.to expose defects in the interaction between software modules when they are integrated. A module is a separate unit of software or hardware.
2.operating errors in the system when combining the approved unit tested modules
3. Bottom-up Integration Testing is a strategy in which the lower level modules are tested first. These tested modules are then further used to facilitate the testing of higher level modules. The process continues until all modules at top level are tested.
Top Down Integration Testing is a method in which integration testing takes place from top to bottom following the control flow of software system. The higher level modules are tested first and then lower level modules are tested and integrated in order to check the software functionality.

  1. Why do we write integration tests? to make sure the functions we tested with unit testing work the same when all the functions are tested together.
  2. What problems do integration tests solve? conflicting functions that appeared to work find on their own but when integrated cause problems.
  3. What are the differences between top-down and bottom-up approaches? top down begins with testing the entire application, then testing the components and bottom up begins with testing the core components first, then testing components one at a time.

  1. Why do we write integration tests?
    Integration testing can expose problems with the interfaces among program components
  2. What problems do integration tests solve?
    To exclude conflicts between modules
  3. What are the differences between top-down and bottom-up approaches?
    bottom up start with unit testing and goes to higher level. Top-down is reverse

  1. Integration testing can expose unit problems before any issues occur in real life program usage. It is also a component in extreme programming which is a method of building a software via testing and revision
  2. it helps identify problems in the interface and support components before system/software is deployed for real live use
  3. bottom up - individual units are tested first followed by progressively higher level combination of units called modules or builds. The top-down IT is exactly 5he opposite - starting with higher level combination of units down to the individual units

  1. To test the interaction between multiple units or modules.
  2. They can expose problems with the interface among program components.
  3. Bottom-up starts with unit testing, then goes on testing progressively higher level of integrations. Top-down starts with high level testing and goes down to lower level (units) testing.

  1. Intergration testing can expose problems with interfaces among program components before trouble occurs in real-world program execution.
  2. Problems with interfaces among program components.
  3. In top-down approaches we start from highest-level modules are testet first and then progressively lower-level modules. In Bottom-up we start from the program units and the progressively testing higher and higher modules .

  1. Why do we write integration tests?
    To ensure that all components of the code work as a whole.

  2. What problems do integration tests solve?
    They expose any problems that may occur when combining multiple units in real world scenarios.

  3. What are the differences between top-down and bottom-up approaches?
    Bottom-up tests the individual units first while top-down starts with integration testing the system as a whole and then testing the units.

  1. Why do we write integration tests?
  • We write integration tests to expose any flaws or issues that occur in programming usage. It is a software development process which programming units are combined and tested as groups in multiple ways.

  1. What problems do integration tests solve?
    -The problems that integration tests solve are the flaws or issue that occur for the programming usage.

  2. What are the differences between top-down and bottom-up approaches?

  • The differences between bottom-up and top-down approaches are that bottom-up approaches begin with unit testing, followed by tests of progressively higher-level combinations of units called modules. While top-down approaches generally begin with the highest-level modules being tested first.

  1. Why do we write integration tests?

To identify program problems before they appear in the real world.

  1. What problems do integration tests solve?

Integration testing can expose problems with the among program components before trouble occurs in real-world program execution.

  1. What are the differences between top-down and bottom-up approaches?

There are two major ways of carrying out an integration test, called the bottom-up method and the top-down method. Bottom-up integration testing begins with unit testing, followed by tests of of progressively higher-level combinations of units called modules or builds. In top-down integration testing, the highest-level modules are tested first and progressively lower-level modules are tested after that.

  1. To fix problems before hand

  2. Interface problems

  3. top down - testing the whole system and then the units where bottom up is testing the ints first
