  1. Testing small part of code, here the unit (like function)
  2. Refactoring is to change code internals without touching the externals like UI or API
  3. First we test units that those are fit to use, do what they suppose to do. Then we can move tests to higher level.

  1. Unit testing is testing of the smallest testable unit in development.
  2. Documentation. Unit testing documents the way the unit is supposed to behave. This way there is something accurate to compare to after refacturing.
  3. Since you’re resting from the smallest unit, the realities discovered there leads the design process. So you’re not building an entire project and then going down through the code changing small things to fix the end result of the software. You’re building each unit above the other based on the testing of the one below.

  1. What is Unit Testing?
  • “Unit testing” is a method of testing by which individual units of source code are tested to determine if they behave correctly. A unit is the smallest testable part of an application - usually a method of a class.
  1. 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 tests are usually written for the public methods (the interface) of a class and document WHAT they are supposed to do. While performing refactoring we change HOW given method returns its result. So it does not matter what exactly steps are performed within a given method as long as the result that is returned (and verified by a unit test) is the expected one.
  1. How does Unit Testing help the bottom-up testing approach?
  • Unit testing helps reduce uncertainty in the code units thus ensuring (and documenting) what the smallest units of code do. Afterwards the system can be tested as a sum of its parts by using the “Integration testing” approach.

    Unit testing allows the programmer to refactor code at a later date, and with unit testing make sure that 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 refers to testing individual units of source code within an application to see if they meet the criteria for use.

  2. Unit testing would allow the programmer to refactor code at a later time and make sure the module still functions correctly. 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.

  3. Unit testing helps reducing uncertainty in the units themselves. By testing the parts of a program first and then testing the sum of its parts, it would help simplifying integration testing.

  1. Unit testing, is the testing of units of the code to insure they work correctly.

  2. Unit testing is important for refactoring because, you want the code to work the same as before.

  3. Unit testing helps the bottom up testing approach, as it means you can identify where the error is, as you are testing individual units of the code.

  1. Unit testing is the individual testing of components of a software to determine whether they fit or not. This assists in establishing whether the software components perform correctly and continues when any changes to the individual component code is made without affecting the intended output from the beginning. As a software testing method the individual units of source code which are sets of one or more computer program modules together with associated control data, usage procedures, and operating procedures are tested to determine whether they are fit for use
  2. Refactoring is the process where the software system is changes in such a way that it improves the internal structure of the source code without altering the function of the code .According to wikipedia, Refactoring is intended to improve the design, structure, and/or implementation of the software, while preserving its functionality.
  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. Once the lower level modules are tested and integrated, then the next level of modules are formed. Unit testing helps in bottom up testing as follows:
  • Fault Localization is easier.
  • Possibility to obtain an early prototype.
  • Critical Modules are tested on priority; major design flaws could be found and fixed first.

  1. Unit testing is done to test parts of the source code to determen if it is fit for use.

  2. To ensure that the code works properly without any errors.

  3. Doing unit testing will facilitate the sum testing of all the parts of code which will make it easier for integration testing.

  1. What is Unit Testing?
    A method of testing individual units of source code to make sure they are fit for use, which each unit is the smallest testable part, e.g. an individual function or procedure.

  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?

Unit testing is important for refactoring because it ensures that all components of the code are working properly after a change has been implemented.

  1. How does Unit Testing help the bottom-up testing approach?
    The bottom-up testing approach is aided by unit testing in that each component is tested before the entire sum of components is tested.

Bottom-up approach involves testing low-level modules and then coming up the structure to test the lower units with higher-level units until all the units are tested. Therefore unit testing is the building block of the bottom-up testing approach.

  1. What is Unit Testing? - Testing the individual and smallest testable components of the source code of an application. This is done to ensure that the code meets the design expectations and executes as intended exposing any problems early in the development cycle.

  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? - In order to facilitate change unit testing allows programmers to restructure code at a later date ensuring that it still performs the intended task and works correctly. Whenever a fault is detected it can quickly be located and corrected.

  3. How does Unit Testing help the bottom-up testing approach? - By first ensuring the individual components of the code work it is easier to integrate additional components, locate and correct any faults.

It allows faults to be recognized and remedied quickly and allows for up to the second accuracy.

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

Since bottom up testing is for testing each part of an application and subsequently the sum of its parts, it makes sense that unit testing is the best and most thorough way to begin the process to help ensure the pieces all work as they should before testing the application as a whole.

  1. Unit testing is the testing of an individual function or procedure.

  2. Unit testing is important for refactoring to ensure that the code still performs the tasks for which is was designed, especially after modifications / improvements. It also helps maintain the focus of the individual functions and procedures.

  3. It helps ensure the robustness / integrity of the code base from the bottom up. It’s difficult to test the functionality of all the small components of a project manually, so unit testing provides this assurance for a project as it grows in complexity.

  1. Unit testing is a verification that the code works and performs the way the programmer expected it to.
  2. Refactoring may work in one area of the system, but break something in another area. For example, the new code may work on the API, but cause errors on the server.
  3. Unit testing helps by ensuring that code works at the user level before the entire system is implemented. This bottom up method helps ensure there are less bugs as the software is developed.
