1.It is the individual testing of separate elements of source code with a view to finding problems in functionality.
2.In the case of refactoring, unit testing is important as it will allow the developers to have ready made unit tests for each function to help quickly identify problems and facilitate any change in the source code.
3.Unit testing makes integration testing easier as each part on it’s own is tested before trying to connect pieces of code.

1.) What is Unit Testing?
Unit testing is a method by which individual units of source code are tested to determine if they are fit for use.

2.) Refactoring means that you change and (hopefully) improve the internal structure of the code without changing the behaviour of the code. For example, developers may change a piece of code in order to make the code run faster but still perform the same task. Why is unit testing important for refactoring?
To make sure the module still works correctly.

3.) How does Unit Testing help the bottom-up testing approach?
By testing the parts of a program first and then testing the sum of its parts, integration testing becomes much easier.

  1. Unit Testing is a testing procedure where units of source code (the smallest components) are tested. Its testing the application piece by piece.
  2. Unit testing is important for refactoring as it ensures that should the source code be changed the programmer would have a an available (and already built) unit test for that component. This speeds up the development and testing of applications.
  3. Unit Testing helps the bottom-up testing approach by reducing uncertainty in the units themselves. Testing the individual parts, then the sum of the parts which leads to easier integration testing.

    Unit testing allows the programmer to refactor code at a later date, and make sure the module still works correctly (e.g., in regression testing). The procedure is to write test cases for all functions and methods so that whenever a change causes a fault, it can be quickly identified and fixed.

      It is important to every project, to get deeply test ed to work, by that, the app is like "beta" and you like worker can test every function and make it better.

    To ensure the projects work well and everything is perfect for the final client.

    It test the program and then every part and bottom, it become easier to test and to see the problems (if there is anyone).

For example, developers may change a piece of code in order to make the code run faster but still perform the same task. Why is unit testing important for refactoring?

Unit tests make it easy for the programmer to check wether a piece of code is still working properly. After the refactoring changes have been made the unit test can help determine if the code is still passing the tests.

By testing the parts that make up the whole first one can test from the bottom-up.

  1. What is Unit Testing?
    A goal of an unit testing is to isolate each part of the application and validate it’s functionality.

  2. Refactoring means that you change and (hopefully) improve the internal structure of the code without changing the behavior of the code. For example, developers may change a piece of code in order to make the code run faster but still perform the same task. Why is unit testing important for refactoring?
    An output of the unit testing should still remain same even if the code is refactored by the developer to maybe achieve performance or simplify it. thus having a unit test handy will speed up the testing

  3. How does Unit Testing help the bottom-up testing approach?
    By testing the parts of a program first and then testing the sum of its parts makes the integration testing much easier

  1. What is Unit Testing?
    Unit testing is a method to test small parts (individual units) of source code to determine if the individual units of code functions as expected.

    Unit testing is important to determine that the code still functions as per expectation even after refactoring the code at a later time.

  3. How does Unit Testing help the bottom-up testing approach?
    Unit testing allows parts of the code to be tested individually to give confidence to code quality before the parts of code are integrated.

1, Unit testing in programming when each individual code from the source has been tested.
2, Any mistake or fault can be easily identified and fixed, you don’t have to change the whole program as each module is been tested individually.
3, You start testing at the very basic

  • What is Unit Testing?
    Is a way of testing a unit, the smallest piece of code that can be isolated in a system.
    A unit can be almost anything, a line of code, a method ect. smaller is better.
    Smaller tests give you a much more view of how your code is performing.

  • Refactoring means that you change and (hopefully) improve the internal structure of the code without changing the behavior of the code. For example, developers may change a piece of code in order to make the code run faster but still perform the same task. Why is unit testing important for refactoring?
    Unit tests should be set up before refactoring to ensure routines still behave as expected,
    With unit testing in place, refactoring is then an cycle of making a small program transformation,
    testing it to ensure correctness, and making another small transformation. If at any point a test fails, the last small change is undone and repeated in a different way until the program moves from where it was to where the programmer want it to be.

  • How does Unit Testing help the bottom-up testing approach?
    Helps by test the lowest level components 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. What is Unit Testing?
    This is a method used in computer programming. By this method each individual unit of source code is tested to determine if is compatible for use.

  2. Refactoring means that you change and (hopefully) improve the internal structure of the code without changing the behavior of the code. For example, developers may change a piece of code in order to make the code run faster but still perform the same task. Why is unit testing important for refactoring?
    Unit testing allows developers to refractor code at a later date (in regression testing). Test cases are written out and this detail allows to quickly fix issues if error occurs during our test.

  3. How does Unit Testing help the bottom-up testing approach?
    In a “bottom-up” approach it may reduce uncertainty in each units performance to standard requirements. This in turn helps with integration testing, once we know that each unit has been verified, integration tests are easier to perform.

  1. Unit testing is the verification of software at the lowest possible level, such as at the functional level.
  2. So that you can verify that you have not introduced any bugs or unintended consequences.
  3. By starting with unit testing, you can verify that the simplest tasks are preforming correctly and then move to the next higher level once the lowest level is completed and verified.

Unit testing involves testing a component in isolation, to ensure that it provides the desired result.

Unit testing is important in refactoring in order to test the improvements while at the same time validating that these changes don’t impact the results that are produced by the code.

Unit testing provides for validating each separate function or block of code, so that these blocks can be trusted as they integrated into the overall software. You start with the basic building blocks and build up from there.
