  1. so units can be tested in groups and multiple ways.
  2. Exposes problems with the interfaces among program components before real-world in program execution.
  3. 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 ensure the quality of the application functionality at launch. Pre-Development we want to test for any internal flaws in security, extensive functionality and completeness.

2.It can help “expose problems with the interfaces among program components before trouble occurs in real-world program execution”

3.Bottom up approaches are like checking your math solution first and then working your way back to the initial question. Top down is the traditional way of checking the lists on the way down starting with the higher levels first

  1. Why do we write integration tests?
  • To expose if any problems with the interfaces among program components before trouble occurs in real-world program execution.
  1. What problems do integration tests solve?
  • To find out if integration works, with all the different pieces of code together without errors.
  1. What are the differences between top-down and bottom-up approaches?
  • Top-down, the highest-level modules are tested first and progressively lower modules are tested after that.
    Bottom-up, starts with Unit testing, followed by tests of progressively higher-level of combinations of units called Units or builds.

  1. Why do we write integration tests?
    Integration testing is conducted to evaluate the compliance of a system or component with specified - to see if the interphases between units are working
  2. What problems do integration tests solve?
    Interphase issues between unit components.
  3. What are the differences between top-down and bottom-down approaches?
    Top-down testing is an approach to integrated testing where the top integrated modules are tested and the branch of the module is tested step by step until the end of the related module. While in bottom-up approach, the lowest level components are tested first, then used to facilitate the testing of higher level components.

Program units are combined and tested as groups in multiple ways.

It can expose problems with the interfaces among program components before trouble happens in the real world.

Bottom up integration testing begins with unit testing followed by higher combinations of units called modules or builds. Top down starts at the highest level modules / builds and then works down to testing at a unit level.

NOTE: I am UNABLE TO VIEW THE ARTICLE by following the TechTarget hyperlink. It flashes the article and then covers it with a required sign in. It requires a lengthy registration beginning with a corporate email address which I do not have.

I have read previous answers in this blog to understand the topic and answered accordingly.

  1. Why do we write integration tests?
    A: To test individual components (units) of code to verify their interaction with various subcomponents and detect interface defects.
  2. What problems do integration tests solve?
    A: It will expose problems in the component interfaces BEFORE final deployment of new code.
  3. What are the differences between top-down and bottom-down approaches?
    A: TOP DOWN: Test the higher level modules —>subsystems—>lower level components. This method identifies lost module branch links.
    BOTTOM UP: Test lower level components first and then work the way up to higher level components. This method facilitates efficient error detection.

  1. Why do we write integration tests?
    To expose issues in interfaces among program components before moving to real-world program execution.

  2. What problems do integration tests solve?
    To make sure the program is working correctly and solves interoperability problems.

  3. What are the differences between top-down and bottom-down approaches?
    Top down starts its tests at higher levels and goes all the way down the code, bottom down does the opposite.

  1. To test the various applications as a whole program to check that they function as intended.
  2. Applications can function standalone but doesn’t mean they will execute flawlessly when combined with other units. Integration tests solve the issues that arise from those cross units functionality.
  3. Bottom-up testing is testing each individual unit on its own, then combining it with the next set of units and testing those as a whole, and repeated until the all of the units are combined and functioning as intended. Top-down is the opposite of bottom-up as it starts with all of the units as a whole and works down.

1.for testing the combinations of units in multiple ways
2. the problems of interfaces that may occur in the real world program execution
3. top-down starts from the top as in a build of units and goes down to a unit and bottom-up(not down) starts from a single unit to a build of units

To test “higher-level” modules and continuous revision so the product is working correctly.

Usually helps with larger scale testing like testing if multiple units work or if interfaces work. This is different than unittesting because unittesting is more focused on fixing the smaller components.

Top down is more of testing the collective units of code and then testing the smaller units to make sure everything is working. Basically it’s testing higher-level modules and then lower-level modules right after. Bottom-down is basically the opposite where the smaller units are testest first and then work the way up to the larger units.

  1. **Why do we write integration tests?
  • to test different units/components functionality together
  1. **What problems do integration tests solve?
  • possible communication problems between units/components and linking errors
  1. **What are the differences between top-down and bottom-down approaches?
  • in top-down you test the high-level functions first and bottom-down you test low-level in small units individually

1- Tests different units/components functionality together

2- Possible communication problems between units/components and linking errors

3- Top-down approach first tests the collective units of code and after de smaller units, the bottom- down, is the other way around, starts first with the smaller units and then the collective ones

  1. Why do we write integration tests?

Intergration test is a process in which program units are combined and tested as groups in multiple ways. It is crucial in software development that takes a meticulous approach to building a product by means of continual testing and revision.

  1. 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.

  1. 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. In top-down integration testing, the highest-level modules are tested first and progressively lower-level modules are tested after that.

  1. Why do we write integration tests?
    Its to test that all components of the code developed, works with other components
  2. What problems do integration tests solve?
    It identifies any problems early on when the code is pushed in to the build server.
  3. What are the differences between top-down and bottom-down approaches?
    Top down server starts at the high level function while bottom up starts at unit testing and followed by progressively builds different combinations together.

The link to the article was broken for me. I read other answers in formulating these because I could not get to the article.

  • Why do we write integration tests?
    To create a process in which program units are combined and tested as groups in multiple ways.
  • What problems do integration tests solve?
    They can expose problems with or between components before deploying live.
  • What are the differences between top-down and bottom-down approaches?
    Top Down- tests the top level components first and then drill down to component or units tests as needed to find problems.
    Bottom Up - tests units first and then increasingly tests larger components before testing the whole.

  1. Integration tests check components in different combinations or modules to expose potential problems among components.

  2. Integration tests check real use application and performance among components to make sure users do not experience problems on their systems.

  3. Top down integration testing starts by testing higher level modules first and then working down to smaller level modules. Bottom up testing begins with unit testing and works up to module testing, or builds.
