Unit Testing - Reading Assignment

[ArtCenter1]

• What is Unit Testing?
  Unit testing is the testing of individual part of the software to see if it fits the purpose.
• 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 the programmer to refactor code at a later date, and make sure the module still works correctly
• How does Unit Testing help the bottom-up testing approach?
  Unit testing make sure that each function of the unit works first before integration test therefore avoid complication.

1. What is Unit Testing?

Unit testing is a method of testing which strives to test the functionality of a a program on the lowest modular level, with units usually being the interface functions.

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 helps assert ,that the functionality has not been effected by the refactoring, and that the code still returns the same results as expected by the unit test.

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

It allows the testing of the smallest parts, which later in the integration tests, helps assure that the program as a whole functions correctly

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

2.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. Depending upon established development practices and unit test coverage, up-to-the-second accuracy can be maintained. In unit testing we test each the module separately.

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

1. What is Unit Testing?
   – 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?
   – 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.

Readily-available unit tests make it easy for the programmer to check whether a piece of code is still working properly

3. How does Unit Testing help the bottom-up testing approach?
   – Unit testing may reduce uncertainty in the units themselves and can be used in a bottom-up testing style approach. By testing the parts of a program first and then testing the sum of its parts, integration testing becomes much easier.

Cause we will make sure that all the components are working properly and sufficiently. Also in some cases we might apply small changes that will ends up adding more efficiency to the app.

3. By testing the smallest individual parts separately first (bottom-up), and then all together as a whole, we can target and minimize errors.

[Nicksta]

1. Testing one of the smallest testable parts of an application.

2. So the developers can specify which part of the code needs refactoring

3. By testing the parts of a program first and then testing the sum of its parts, integration testing becomes much easier. Basically, testing is run from starting with the smallest building blocks going up to the whole application.

[Gus]

1. Unit testing is the process of testing the smallest component of a project to see if tit complies with requirements.
2. Refactoring is just like writing new code and therefore need to go through the testing procedure the same as new code.
3. 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.

[Adam1]

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 because it it tests the performance of the new code before its put to use.

3. In bottom up testing you can test individual sections of the code making the final test more secure.

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

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?
   Prevents unnecessary testing.

3. How does Unit Testing help the bottom-up testing approach?
   Unit testing makes integration testing easier as each part on it’s own is tested before trying to connect pieces of code.

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

Response:

1. Unit testing is when the units of developed source code are tested to see if they work correctly.
2. If you are going to refactor the structure of the code, you still want to make sure that it behaves as originally coded. The only benefit of running code faster is if it’s running right.
3. By testing individual parts of the code, you can narrow areas that need to be worked on and fix them as needed (quickly) so that when you run the entirety of the code it is more than likely to run smooth.

[javier_ortiz_mir]

1. What is Unit Testing?
   its a part of software development process, by which each unit of the software (that must also be defined accordingly) is tested individually, by different means. The goal of unit testing is to isolate each part of the program and show that the individual parts are correct.
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?
   Bacause it facilitates change. I found this at a later part of the same article:
   Design patterns, unit testing, and refactoring often work together so that the best solution may emerge.
3. How does Unit Testing help the bottom-up testing approach?
   because by testing the parts of a program first and then testing the sum of its parts (bottom-up approach), integration testing becomes much easier.

[tuchtech1]

1. What is Unit Testing?
   Unit testing is manual or automated performance testing of the smallest possible unit of code in an application.
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 will make sure that the code still functions as planned regardless of any internal changes to the unit.
3. How does Unit Testing help the bottom-up testing approach?
   By knowing that their code needs to be easily testable in units, developers are encouraged to think in and create code of independent units and which reinforces the bottom up approach of robust and readily testable software.

[D1alZer0]

1. Unit testing in computer programming, 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 a program first and then testing the sum of its parts, unit testing makes integration testing much easier.

[VanellaVader]

1. Unit testing is the process by which the smallest individual components(units) of a code are tested.
2. Unit tests can determine how/if the code works which is helpful with sustaining maintenance and for determining which units of code are at fault so that they can be easily identified, changed, and tested to make sure they still run properly.
3. Testing units of a code from the most essential parts up to the peripherals makes it much easier to integrate different parts of a larger program

[Wxdoc]

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 as it assures a continuous as needed test to assure proper code accuracy and performance.

3. Unit Testing helps the bottom-up testing approach as it test for the individual minute functional parts of a code, in addition to the sum of the entire code.

[JCrypto]

1. Unit testing is a method by which individual units of source code are testing to determine if they are fit to use
2. Unit testing is important for refactoring because you can identify specific errors and make adjustments without causing unintended changes in other areas
   3.The approach involves testing parts of the program first and then testing becomes much easier.

[Kim]

1. What is Unit Testing?
   It’s a method by which individual units are tested to determine if they are fit for use (unit=smallest stable part of an application)
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 unit testing allows the programmer to refactor code at a later date and make sure the module still works correctly, so whenever a change cause a fault it can quickly be identified and fixed.
3. How does Unit Testing help the bottom-up testing approach?
   Unit testing reduces uncertainty in the units themselves.

• 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?

You want to ensure the changes have not introduced unexpected problems.

@ivan

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

As you test individual components with unit tests you build confidence those components function as expected. This allows you to build more complex tests (integration tests) easier.

[ChefAbate]

1. Unit testing is programable testing used to ensure the code is fit for use in the application.
2. Unit testing is important for refactoring because any mistakes in the code will be discovered when a unit test is performed.
3. Unit testing helps thew bottom-up approach it ensures that each piece of the project fits together correctly. By testing the most critical pieces individually before putting together as a whole.
