  1. Unit Testing is a way to run some development code, the smallest testable part and see it perform the function or procedure it was written for

  2. Refactoring is a way to improve the efficiency of the code, by unit testing the refactoring each iteration improves and optimises the code

  3. Bottom up testing means the most basic code functions are unit tested first, if these are successful, then a more complex code functions added and re unit tested, this testing approach is more modular and better integration occurs

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

  2. Unit testing is important for refactoring to ensure that the refactored code still works properly.

  3. Unit testing helps the bottom-up testing approach by focusing on first making sure the individual units of source code work properly before doing integration testing.

1. What is Unit Testing?

  • its a method to test individual units of the source code

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 testings are testing each module separately in the same way
  • problem in the source code can quickly be identified

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

  • reducing uncertainty in the units
  1. testing the parts of a programm
  2. testing the sum of its parts

  1. What is Unit Testing?
    Unit testing is the testing of the smallest possible source code unit able to be tested. This could be even individual functions (procedural programming). This allows to determine if the changed source code is fit for use or if there are any errors in the code. It can not test the absence of errors only the presence of them.

  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 case of refactoring the ready built test allow to test the refactored unit to be tested if it still performs as the previous version and no obvious errors are introduced. This improves the refactoring process as issue can be quickly identified.

  3. How does Unit Testing help the bottom-up testing approach?
    It does simplify integration as it can be assured the units are performing as expected. By testing the parts of a software and then testing the sum of the parts integration testing becomes easier. Therefore the bottom up approach from the single unit to the complete assembly.

  2. The unit testing allows the programmer to refactor code at a later date, and make sure the module still works correctly.

Unit testing involves testing to make sure it performs as required the smallest part of code such as a function or process.
Unit testing is important to ensure that refactoring has not changed the behaviour of the code.
It helps because it begins with the smallest testable code and helps to pin point were a problem is.

Its the verification of “fitabilty” of the smallest possible part of executable source code, evaluating the proper usability in a software of its functions and procedures. Each unit is independent of the system as a whole.
2.
You can locate and rearrange the exact point of failure or of possible performance improvement quicker, saving time and money, you can also use documentation to quick access procedures for new employee or integrant of the source code team.
3.
Ensuring that every unit is working accordingly, reducing likelihood of malfunction when testing the entire system, integration test or bottom-up test, and making the integration of the whole code much easier.

Unit Testing tests the smallest unit of code
Refactoring means that you change and (hopefully) improve the internal structure of the code without changing the behaviour of the code.
The unit test cases have aspects that are critical to the success of the unit, so by using the unit test as design model, you make the entire testing process more efficient.

  1. Unit testing is for testing individual parts of the code.
  2. To ensure it still works like before without errors
  3. Starting with an integration test without doing the unit test first can lead to complications as one does not know what part of a program an error is coming from.

If the code change you make causes an error somewhere else in the code, refactoring can find the cause to the bug/error. 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.

Unit Testing is doing tests on the code. A Unit is the smallest possible portion of code which is able to be tested in isolation in an application.

Assuming the code functioned properly prior to the refactoring, Unit Testing will determine if the new code works in the unit beiing modified.

By determining that each small bit of code is valid on its own developers can move ahead in their areas.

    To ensure every other component on the code works well after this changes has been made. If errors appears, the unit testing its a very important environment to research how to deal with new errors without compromising the main code.

  3. How does Unit Testing help the bottom-up testing approach?
    Each new component has been tested and verified that is fully functional before integrated into the main code, reducing the probability of unknown issues since all components has been tested/fixed.

  1. Unit testing is testing every component of the software.

  2. Refactoring could have mistakes that cause certain component to behave differently. Unit test is to ensure that mistake does not happen.

  3. Bottom-up approach will ensure every part of the program works well as a foundation before proceeding with the integration test. If any error is encountered, this could easily be identified in the specific test area.

  1. Unit testing is a method to test and validate code. A unit is the smallest piece of an application that are possible to test.

  2. The purpose of unit testing is to isolate each part (unit) and test, validate and show that the individual unit behave correct.

  3. In the way of that you test each part in a program separately and then do tests that each part interact with each other in a proper way. This is preferable way to do tests in order to discover and identify error and failure in the program.

  1. Unit Testing is a way of splitting up the practical analysis / testing of a project into batch size units for efficient processing in a testing phase.

  2. Unit testing allows you to come back to a segment or batch of code and update it, see how it runs in test mode, and deploy it to the codebase once it is demonstrably working. In this way, components can be worked on and integrated that solve issues rather than create further unintended consequences.

  3. Unit Testing helps this approach because the constituent parts of the whole can be tested first initially and separately, and also, conversely, the whole model can be tested as the entire ‘sum of it’s parts’.
