  1. What is Unit Testing?
    – Unit testing is a method by which the smallest testable parts of an application source code - such as individual functions, procedures, or modules - are tested to determine if they are fit for use.

  2. Why is unit testing important for refactoring?
    – Unit test makes it possible for errors to be quickly identified and fixed after code is refactored

  3. How does Unit Testing help the bottom-up testing approach?
    – Unit Testing provides test cases that document the appropriate/inappropriate use of the unit which in turn helps in error handling and it reduces uncertainty as it allows for the parts of the program to be tested first which should make integration testing easier later on

  1. What is Unit Testing?
    Testing individual units of code at the smallest level to determine functionality.

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 ensure nothing breaks as changes are made. (regression testing)

  3. How does Unit Testing help the bottom-up testing approach?
    because you’re testing the whole and the sum of its parts which allows for faster more efficient testing.

  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.
A unit is the smallest testable part of an application.
A unit may be an individual function or feature in procedural programming.
Each test case is ideally independent from the others and substitutes can be used to assist testing a module in isolation - for example method stubs, mock objects, fakes and test harnesses.
Unit tests are usually run by software developers to make sure the code meets the design and executes as intended.
Unit testing implementation can be manual with pencil and paper or part of the build automation.

  1. Why is unit testing important for refactoring?
    When the developer is refactoring, they may be improving, upgrading or rewriting a part of the code. Unit testing allows the developer to test specific units of code and make sure the module still works correctly within the whole design/application/software. In unit testing we test each module separately. This means that it’s possible to ensure that changes in one unit of code will result in it still being able to run correctly within the greater structure of the whole design.

  2. Unit testing may reduced uncertainty in the units themselves, and can be used in a bottom-up testing style approach. Developers test the parts of the program first, and then see how it all runs together by testing the sum of the parts.

What is Unit Testing?

A pice of code that invokes another piece of code and checks the correctness of assumptions afterward.

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?

Unit testing record every use cases which allow the programmer to refactor code at later and makes sure the code is still working correct.

How does Unit Testing help the bottom-up testing approach?

Testing the lower parts of a code first and then testing the sum of its part, this makes the integration testing become much easier.

    • It is method by which individual units of source code are tested to determine if they are fit for use.
    A unit is the smallest testable part of an application. In procedural programming a unit may be an individual function or procedure. Unit tests are created by programmers or occasionally by white box testers.

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?
    • Because it allows the programmer to refactor code at a later date and make sir the module still works correctly. This helps to identify a faulty change quickly and get it fixed.
  3. How does Unit Testing help the bottom-up testing approach?
    • By testing the parts if a program first and then testing the sum of its parts, thus integration testing becomes much easier.

  1. What is Unit Testing?
    It is to test individual sections of code to determine if it’s free of error/bugs and good to 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?
    Because as the code is changed and optimized, along the way you may run into issues, so it’s important to test individual changes along the way to make sure you have fully operational software once complete.

  3. How does Unit Testing help the bottom-up testing approach?
    By testing individual parts of a program, one could easily later on down the line integrate changes, which then make integrated testing easier.

    To make sure it does not result into bugs or errors that can screw up the overall code.
  3. How does Unit Testing help the bottom-up testing approach?
    If you do integration testing you may not know where the errors are originating from. Therefore it can be wise to first do unit testing. After doing unit testing first integration testing becomes easier.

  1. What is Unit Testing? - It’s testing individual units of the source code to see if they are usable or not

  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? - It will help the developer check if the code is running properly or not

  3. How does Unit Testing help the bottom-up testing approach? - The way I understand it, it’s best to test and fix smaller parts first before testing if all the units work together. Maybe it can be hard to detect the source of the error if you go straight to the integration test.

*. What is Unit Testing?
Unit testing is the process of taking small, testable units of source code to see if they are fit for use.

*. 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?
It’s important because it allows developers to quickly identify and repair faults. It also allows the refactoring to take place at a later time while each unit of code is being assesed.

*. How does Unit Testing help the bottom-up testing approach?
It helps because the unit testing can test the individual parts of the code as well as the sum of the parts.

  1. in unit testing you are testing the smallest parts of your software and see the output and how it affects the software
  2. because in refactoring you are improving the software, it makes the code more readable, understandable and clean, it is also used to add new features, spot and fix bugs.
  3. it helps for the integration, when you start testing units in groups you could get a different behavior…in my understanding unit testing is so important because it is the best way to see where bugs begin or performance sucks

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?
    With refactoring, unit testing is important as it will allow the coders to have ready made tests for each function. This helps identify issues and easily make changes n the source code.
  3. How does Unit Testing help the bottom-up testing approach?
    By testing the parts of a program first and then testing the total of all the parts, there is more of a chance of being more efficient in finding issues before they become large issues. Integration testing becomes much easier also
