  • Why do we write integration tests?
    A: To evaluate the compliance of a system or component with specified functional requirements. ie. to make sure everything works.

  • What problems do integration tests solve?
    A: This method is very effective for saving time in the integration testing process.
    It identifies problems with the way different program components interact with each other.

  • What are the differences between top-down and bottom-up approaches?
    A: 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.
    Bottom-up testing is an approach to integrated testing where the lowest level components are tested first, then used to facilitate the testing of higher level components. The process is repeated until the component at the top of the hierarchy is tested.

  1. So we can test the functionalities of software. It is a software development process which program units are tested as groups in multiple ways.

  2. Integration testing can expose problems with The interfaces among program components before trouble occurs in real world program execution.

  3. Bottom up testing starts with Unit testing, followed by tests 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? To test the flow between multiple components and ensure its working as expected
  2. What problems do integration tests solve? It allows for components to be tested altogether and ensure they function properly as a whole system
  3. What are the differences between top-down and bottom-down approaches? Bottom-up is when you start with the bottom components and then move up to higher level components. Top-down is testing from the top of the high level component functionality and then branch down to the ends of the related modules.

  1. Why do we write integration tests?
    Integration tests are written to expose program problems when units are combined and before updates are made live in the real-world.

  2. What problems do integration tests solve?
    Code execution errors, undesired outputs, UI issues.

  3. What are the differences between top-down and bottom-down approaches?
    Top-down approach tests highest-level modules first, followed by progressively lower-level modules. Bottom-up approach uses unit testing, followed by progressively higher-level unit combinations (AKA modules or builds).

Why do we write integration tests?
Unit tests only work on individual units, integration test work on the system as a whole

What problems do integration tests solve?
Integration tests expose problems in the linkages and interoperations between software units

What are the differences between top-down and bottom-up approaches?
Top down begins with integration testing the system as one unit amd moves down to test units individidually
Bottom up tests units individually and moves slowly up to test the integration of the system as a whole

  1. Why do we write integration tests?

This is done because you need to combine all the modules from unit testing process and then, using test drivers and test stubs test them together so that you can promply detect any interface bug.

  1. What problems do integration tests solve?

The Integration Tests are all-important for the accurate detection of unexpected interactions between functions or procedures.

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

Top-down approach means that you test larger pieces of software and then you test the smaller sections. On the contrary, Botton-up is when firstly you test small pieces and then larger parts.

  1. In order to test the software from the bottom-up to the top-down approach from the smallest unit to the largest module
  2. They solve scenarios problems that will mimic those the customers’ computers, systems and networks will encounter
  3. Top-down looks at the general, larger modules while the bottom-up takes a look from the individual units that take inputs and outputs into account

  1. Why do we write integration tests?

To identify any faults or defects when all the individual tested units are combined and integrated into a whole system.

  1. What problems do integration tests solve?

units when integrated together do not work during the interaction.

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

Bottom up starts with unit testing and then followed by progressively higher level tests of combination of units known as builds or modules.

For top down, the highest level modules are tested first and then progressively lower level after.

  1. To find out unit codes collaborate.
  2. It finds out code is working together in the greater scheme of things.
  3. Bottom-up you start with unit testing. Top down you start with the protocol. It’s more common with bottom-up.

  1. Why do we write integration tests?
    Integration tests make sure all components work together to reduce problems before the system goes live.
  2. What problems do integration tests solve?
    Integration testing resolve problems between component interfaces before trouble occurs in the real world.
  3. What are the differences between top-down and bottom-up approaches?
    Top-down testing starts with the whole solution then down into smaller and smaller components. Bottom-up testing starts with the smallest units then moves toward the global picture.

  1. To confirm that parts/units of code work together without errors.

  2. Show us possible problems that might occur between different units, so we can test different levels within the application

  3. Top-to-bottom: we start testing the integration of large parts of the code, or main functions.
    Bottom-to-top: we start testing individual parts/module of the code, and then after, we integrate them together.

  1. Doing only unit tests is not enough to assure a correct execution of the new software/app. We need to test every level of the code, and Integration Testing approach does satisfy this necessity, as we not only test single units but also in a “holistic” way, hence, in modules (bigger parts of codes grouping together single units)

  2. We test bottom-up and top-down in order to be able to find (hopefully) every kind of software misbehavior/bugs on every code level.

  3. top-down: we test beginning from high-level modules to low-level modules
    bottom-up: we begin testing units (the littlest pieces) and finish with testing modules, also called builds

  1. Integration testing is crucial to building a product by means of continual testing and revision.

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

  3. Bottom-up integration testing begins with unit testing followed by tests of of progressively higher-level combinations of units. In top-down integration testing the highest-level modules are tested first and progressively lower-level modules are tested after that.

    – Integration tests help discover if modules will interface or interact with each other as intended

  2. What problems do integration tests solve?
    – Integration testing can expose problems with the interfaces among program components before trouble occurs

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

  • In top-down integration testing, the highest-level modules are tested first and progressively lower-level modules are tested after that; whereas bottom-up integration testing starts with unit testing, followed by tests of increasingly higher-level combinations of units called modules or builds.

  3. What are the differences between top-down and bottom-down approaches?
    In bottom-down testing the bottom components are testing and then the higher level components are tested.
    In top-down testing the highest level component is tested first and the testing is done step by step until it reaches the bottom components.
