Unit Testing - Reading Assignment

[Jesse_Bowles]

1.It is when you run individual units of code to make sure they will work for you
2.unit testing allows you to find problems in your code and refractor them at a later date
3. It allows you to test each line then check the output of the lines before to make sure it works in reverse

1. What is Unit Testing? It is 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? It makes 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? It reduces uncertainty in the units themselves. 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?
   Testing the smallest part of the 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?
   It is quicker to identify and fix any faults in the code.

3. How does Unit Testing help the bottom-up testing approach?
   It makes it easy later to perform integration testing.

[Aida1]

1. What is Unit Testing?
   is a method in computer programming by which individual units of source code are tested to find out if they are in right position to be used.

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 programmer whether the code is running like before and being able to quickly identify any of the out coming problems so that it is fixed before to secure the system.

3. How does Unit Testing help the bottom-up testing approach?
   it tests the parts of a program first and then testing the sum of its parts, integration testing becomes much easier.

[gregD]

1. Unit testing is testing individual components of source code, ie a function or procedure.

2. Unit testing is important when refactoring code as it ensures all the individual components are still working once a change has been made.

3. Unit testing helps develop a ‘bottom-up’ testing approach as all the individual components are tested before the assembled code is tested. You then know it is the arrangement of the code that is causing bugs rather than any individual component.

[Kristian_Mitov]

1. What is Unit Testing?
   A method that tests single units of code if it is fit 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?
   Unit testing allows the programmer to change the code at a later stage by keeping the behaviour of the program.
3. How does Unit Testing help the bottom-up testing approach?
   You first test the single units of a program and then the sum of them.

[Harold]

1. Unit testing is a method in programming by which individual units of source code are tested to determine if they are fit for use.
2. Refactoring is essential to refactoring because it allows alterations to the code structure without alternating the code behaviour.
3. The Bottom-Up Testing is helped because by testing the parts of a program first and then testing the sum of its parts, integration testing becomes much easier.

[C.Higbee]

1. What is Unit Testing? individual units of source code are tested to find out 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? you can go in and make changes, then run the module to ensure it is functioning properly.
3. How does Unit Testing help the bottom-up testing approach? You can first test the smaller parts of the program before it is integrated

1. What is Unit Testing?

Unit Testing refers to testing the source code of all the individually testable parts of an application. The goal of unit testing is to assess whether or not all components of a software run as expected. The test includes feeding each component with numerous and different test cases and the tested component must return a specific output for each test case. Any deviation between the actual test output and the expected output implies that the software component is not running properly.

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 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 to quickly identify whether an update in the code has introduced a bug in the updated software component.

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

In bottom-up software testing, the individual software components are tested first, which is followed by testing the software components on the next level, and so forth. Unit testing represents the first step of the bottom-up testing approach and thus the results of unit testing can be used for bottom-up testing.

[Damedius]

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

2)It is important because it can be used to see if the changes made introduced any bugs or unintended consequences.

3)It allows you to test smaller pieces of code before integrating them.

[jude]

1. Unit testing is running a small component of a software making sure it runs as intended.
2. Unit Testing is very important in refactoring because we gain insight into what that component is, and what it is capable of doing. When we refactor, we are changing/restructuring the code while making sure the results of the component remains the same.
3. A unit Test helps the bottom-up testing approach in that it helps trap problems early… and prevent those problems to propagate to other parts of the software.

[kwaben]

1. What is Unit Testing?
   Testing the smallest unit of code in an application to make sure it behaves as expected.
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?
   A small change can introduce a mistake so must be regression tested to ensure that the change has not affected expected behaviour
3. How does Unit Testing help the bottom-up testing approach?
   If all units work then they can be integrated. And one progresses up the hierarchy with confidence.

[MrAndres]

1. What is Unit Testing?
   It is a process by which developers test specific units of source code to determine if they are fit for use. The idea is that the code is well designed and that it behaves as intended. Unit tests detect issues early in the development cycle. Unit testing aims to isolate each part of the program and confirm that the individual elements are accurate.

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 essential for refactoring because it facilitates change; whenever a change causes a fault, it can be quickly identified and fixed.

3. How does Unit Testing help the bottom-up testing approach?
   It helps by simplifying integration by testing the parts of a program first and then testing the sum of its parts; integration testing becomes much more manageable using this approach.

[petroslk]

1. Unit testing: when individual units of the source code are tested to check if they are fit
2. Because by changing a piece of code, there is a possibility to affect the whole program. So by using unit testing you avoid this results
3. By testing the parts of a program first and then the sum, helps to reduce the uncerainty

[William_Kuang]

1. “Unit Testing” is a source code testing method where parts of the source code are tested separately from one another in groups of “units”.

2. Because unit testing allows the developer to see how efficient a part of the source code is and whether a particular unit of the code is the issue causing any inefficiencies within the whole source code.

3. Unit testing will help with bottom-up testing by providing more certainty with the bottom-up tests, thus making the whole test procedure more effective and smooth with less redundant testing.

[FreeBird81]

1. Individual units of source code are tested to determine if they are fit for use. Typically automated tests written and run by software developers.

2. Unit testing allows a programmer to refactor code to make sure the module still works correctly.

3. It may reduce uncertainty in the units themselves, by testing the parts of a program first and then testing the sum of its parts.

[dhealy7]

1. A method of testing units of code exclusive of other code, to determine its fit for use. I helps detect coding issues early in the development cycle, and is consider good coding practice.
2. Unit testing allows for the quick detection of bugs, when refractoring is carried out
3. It helps by allowing for segmented testing before integrated testing, which helps identify bugs easier

Leave your answers to the questions below in this thread. If you have any questions or you want to discuss something connected to the assignment feel free to do it in this thread as well, but please everything to the topic.

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

1. testing of certain part of the code to found any bugs.
2. In the case of refactoring, unit testing is important as it will allow the developers to have ready made unit tests for each function to help quickly identify problems and facilitate any change in the source code.
3. first testing parts of the code will make integration testing easier

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

2. Unit testing enables established development methods and coverage of unit tests. This means that programmers who are refactoring can quickly identify and fix faults within each module. This ensures the maintenance of accuracy up-to-the-second.

3. Unit testing can be used in a bottom-up testing method to eliminate uncertainty in the units themselves. Integration testing is made considerably easier by testing the parts of a software first and then the sum of its parts.
