Unit Testing - Reading Assignment

[Gagnon]

1. Unit Testing is where 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 module is still working correctly.
3. Unit Testing can help the bottom-up testing approach by reducing uncertainty in the units and by testing parts of a program first and then testing the sum of its parts. This makes integration and identification of where a problem is occurring much easier.

[Plamen_Petrov]

1. A method by which individual units of source code are tested to determine if they are fit for use.

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

3. By testing the parts of a program first and then testing the sum of its parts, integration testing becomes much easier.

[MFLittle]

1. What is Unit Testing?

Unit testing is testing the behavior/outputs of a “unit” of 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 testing allows you to compare the results before/after refactoring to ensure that refactoring didn’t break anything.

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

It allows you to test the units (parts) first before testing the sum of the parts in integration testing which makes it easier to identify and isolate any errors or inconsistencies.

[Valdis]

1. What is Unit Testing?
   A process of checking that the software will not fail when in 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?
   By definition you are modifying the code to make it more efficient. The result is a ‘different’ code and it is important to test that it sill works as the initial code did. Hence the unit test of it.
3. How does Unit Testing help the bottom-up testing approach?
   By the time you get to test the integration of the units you do not have the risk of individual units being faulty.

[Goosie]

1. What is Unit Testing?
   Is testing parts of the software.

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 identify problems and help to find the code which should be changed in case of faillure.

3. How does Unit Testing help the bottom-up testing approach?
   By testing components first, integrations of all the components together becomes more easier later on.

[Jonny]

1. What is Unit Testing?

• Testing small self contained sections of code individually and apart form the code base as a whole

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 ensures that the essential functions of a piece of code have not been altered by the refactoring and the code will still function in the larger context of the program

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

• It allows the smallest functions of a program to be built fir smallest and then larger functions to be built from those and slowly the entire program is assembled from smaller functions

   Unit Tests help by testing the parts of a program first, and then testing the sum of all parts, which makes integration testing easier.

[paschkka86]

1. Unit Testing is a method by which individual units of source code are tested to determine if they are fit for use. An unit is the smallest testable part of an application.

2. Unit Testing is important for refactoring, because with this its possible to check only the refactored part and don´t have check the complete code, if you just change a small part. This way, you save a lot of money and time.

3. Unit Testing help the “bottom-up” testing approch, by testing the parts of a program first and then testing the sum of all parts.

[DKSA]

1. Unit tests are typically written and run by software developers to ensure that code meets its design and behaves as intended
2. Whenever a change causes a fault, it can be quickly identified and fixed.
3. Testing the parts of a program first and then testing the sum of its parts, integration testing becomes much easier.

*What is Unit Testing?
A method by which individual units of source code are tested to determine if they are fit for use.

*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?
In continuous unit testing environments, through the inherent practice of sustained maintenance, unit tests will continue to accurately reflect the intended use of the executable and code in the face of any change.

*How does Unit Testing help the bottom-up testing approach?
Unit tests involves testing parts of the program first (bottom) which constitute the whole system (top). So testing parts first and then testing the sum of its parts, integration testing becomes much easier.

[AliasFresh]

1. What is Unit Testing?

unit testing is when you test the individual lines of code in isolation for errors before integrating into the source.

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 shows us it works in isolation. Refactoring let’s us know if the functionality remains after integration and if compromised, errors are easily identified and addressed at this stage

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

A structure is only as strong as its foundation. Unit testing inspects the foundation. Then refactoring tells us how well the rest of the structure fits or integrates with the foundation and the rest of the structure. It is faster, much more efficient and ultimately cheaper to build a structure correctly the first time as opposed to building a complete structure and then trouble shooting the foundation. It just might collapse on you before completion.

1. What is Unit Testing?

Breaking down code into the smallest possible fraction and then making sure it works accordingly.

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?

Makes testing the reorganized code more expedient

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

By testing the smallest units first, you can pin-point where the issue is when you find an error

[tanja]

1
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. (function, procedure, etc)

2
allows the developers o have ready made unit tests for each function (faster identification and repair of problem)

3
By testing the parts of a program first and then testing the sum of its parts, integration testing becomes much easier. (Instead of meticulously testing everything first, then breaking it down to smaller pieces) More direct solving of issues.

[mkhuang]

1. What is Unit Testing?
   It is the testing of individual elements 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?
   Helps to quickly identify issues and make the necessary changes to the source code
3. How does Unit Testing help the bottom-up testing approach?
   By testing the individual parts of the program and later the program as a whole, that is a more efficient and easier way to identify the problem.

[Thaddeus19]

1-What are unit tests?
These are the tests that are carried out separately in each unit or module of the code to verify its correct operation and / or performance.

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 can change a code snippet so that the code runs faster but still perform the same task. Why are unit tests important for refactoring?
Since when detecting a failure or improvement we do it in a part of the code before integrating everything and thus we do not affect the program in general or generate a bug in some other point of the program when it is already in operation.

3-How does Unit Testing help the ascending test approach?
By testing the different parts we identify and solve more quickly and efficiently the bugs they have.

[cryptokaritz]

1. Unit testing is testing of specific elements of source code to find problems.
2. Unit testing is important for refactoring to assure that the code is working better after the refactoring changes are included.
3. Unit testing helps verify each piece of code is viable before they are integrated into the entire system. Unit testing tests the pieces; integration testing tests the whole. So unit testing makes integration testing easier.

[Ray]

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 allows the programmer to refactor code at a later date, and make sure the module still works correctly.
3 By testing the parts of program make it easier to test one part instead of full code.

[laketravisgirl]

1. Unit Testing is when individual functions or procedures are tested to make sure they work as expected.
2. Unit testing is important for refactoring to make sure that any new changes haven’t broken the program.
3. Unit Testing helps the bottom-up testing approach by making sure each small piece of the program works as expected. Knowing that helps make integration testing easier.

[Chantal]

1. Unit Testing is the action to test each functionality separately (in isolation), in order to check smooth running. We perform unit testing on new features AND on all the main previous functionnalities, when we add new features or modify any code.

2. Unit testing is important for refactoring, because you need to check immediately that your new code has no impact on the functionailty and the performance of the system. Regression testing can be automated and launched by the developer in one click, each time he changes the code ; in consequence he will gain a lot of time.

3. Unit Testing help the bottom-up testing approach by performing a first layer of tests and avoiding to go ahead with bugged version when the developer performs the integration. The main bugs will be fixed immediately, before the integration.

[Fairway]

1. In computer programming, 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.
2. To determine if all other functions intended by the unit still works.
3. By testing the parts of a program first and then testing the sum of its parts, integration testing becomes much easier.
