Unit Testing - Reading Assignment

[pmgoff]

1. What is 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. In procedural programming, a unit may be an individual function or procedure.

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? Adjusting the code could cause other problems elsewhere in the code structure. Good testing will help prevent conflicts between any changes to a single instance and the rest of the program.

3. How does Unit Testing help the bottom-up testing approach? Bottom-up testing isolates segments of code that can be troublesome. Unit testing helps find errors early on in the development, before problems manifest through the larger project.

1. A method to test individual pieces of code.

2. To make sure that the same function is still fulfilled.

3. Test different components and then the whole of those component in turn to make sure everything is in working order.

[Ozarkshrub]

1. What is Unit Testing?
   A. Testing the smallest working part of code for a program to ensure it functions as needed.

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?
   B. to ensure the improvement doesn’t cause the new piece of code to foul up another section.

3. How does Unit Testing help the bottom-up testing approach?
   C. Testing the individual pieces will help the overall integration testing.

[Zaqoy]

1. What is Unit Testing?
   Testing pieces of code, one at a time, to confirm expected functionality
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 are able to quickly retest the new structure of the code, to ensure the expected output is still produced
3. How does Unit Testing help the bottom-up testing approach?
   Each individual component is tested prior to testing the entire sum of components. This helps narrow down where the issue occurs.

[TuomoP]

1. What is Unit Testing?
   Method where different parts of source code are tested if they are ok to use. Units could be even as small as functions or procedures. Ideally each test is independent from each other.

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 allows developers to see if code is still working properly after refactoring, and problems can be found early.

3. How does Unit Testing help the bottom-up testing approach?
   Testing parts first and then the end result of them makes integration testing easier.

[rishibehl4]

1. It is a method by which individual units (or components) of a source code are tested to ensure they perform as intended and therefore are fit for use.

2. It allows a software developer to refactor at a later date and still ensures that they work as intended.

3. Unit Testing allows to test units/parts of a code first and then test the sum of its parts as a whole. This gives thoroughness and confidence to a software developer about functionality.

[AndrewM]

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

Unit testing makes it easy to check whether a piece of code is still functioning correctly after modification.

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

[BlissBang]

With Unit Testing, individual code units such as functions, are tested to find out if they are fit to use and work as they should.

You will be able to compare if a code runs faster or if refactoring improves compared to the previous format of the code.

By testing each of the components and then seeing them perform altogether as a sum, you gain insights into the efficiency of the whole and its parts.

Hey guys!

1. What is Unit Testing?
   A series of computational executions by which units of source code are tested one by one to determine if they are acceptable for use.
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?
   Because by unit testing you will be able to see if your proposed code will work while maintaining old code.
3. How does Unit Testing help the bottom-up testing approach?
   It tests the parts and then the whole making integrating easier.

[A_Olson]

1. Unit testing is the practice of testing individual units of source code, such as functions, to make sure they are free of bugs and good to use.

2. Unit testing allows developers to refracture at a later date, while still making sure that the source code works as intended. Any fault can be quickly identified and fixed.

3. It helps developers find problems early in the development cycle, allowing the project to move forward without catastrophic failures later on.

Unit testing allows the developer too refactor at a later date and make sure that the module works correctly.

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

It reduces uncertainty in the units themselves and make integration testing much easier.

[thenode369]

1. What is Unit Testing?
   A process of testing each of the smallest individual components ‘units’ of source code to ensure they meet requirements and expectations of application. These could be an individual function or a 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?
   To ensure that the function and behaviour of the code is not ‘broken’ and that it still operates in the same expected manner. That the changes in this case, provide the same level of functionality but with an improvement in running speed of application.

3. How does Unit Testing help the bottom-up testing approach?
   By starting with Unit Testing on the parts of the program first, then building up to test the sum of the parts when adding the components together, giving confidence in each parts performance that also aids Integration Testing.

[Marzio]

1. Testing individual parts of the code before integrate it into the whole work
2. Unit testing is very important when refactoring because change a piece of code might lead to unintended changes somewhere else…
3. It is easier to identifie problems in small part of codes than when is integrated in the software

[mitja]

1. What is Unit Testing?
   It is the individual testing of separate elements of source code with a view to finding problems in functionality.
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 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. 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.

[Shinde]

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

2.Because refactoring shouldn’t necessarily affect the inputs and outputs to a given function, the unit tests can effectively determine if logic/functionality was altered.

3. Unit tests involves testing parts of the program first before they get integrated into the whole system. So testing parts first and then testing the sum of its parts, integration testing becomes much easier.

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

1. Unit testing is testing small parts of the code like individual modules, functions or integrations etc.
2. It’s important to make sure that the code actually runs well, does the intended task and isn’t broken by refactoring.
3. It’s beneficial to test parts of a program, to understand where the problem is, so it can be fixed earlier rather than later. You can also create different ways to test the same unit, which lowers the chance of potential failures.

[Emmerich]

1. The testing of the individual units of an app.
2. The result should still be the same, even though the code of the unit has changed/improved.
3. You test the individual units first before testing the syste as a whole.

[Kamlesh_Joshi]

1.unit testing is basically tests in which particular unit of source code are tested to determine they are fit to use. A unit is a smallest testable part of a application
2.By unit test will help the developer know where the error is. Although not all the errors could be decoded with unit test. Refactoring code helps the developer to check what changed the behaviour of the program. So that final product is without errors
3.Unit testing helps to assure that every component is working and also works after any revision in code is made

[levinardo]

1. What is Unit Testing?
   A method to determine whether a section or part of code will produce the expected results or not. This is not about testing the whole integrated source code (sum of all units), but rather very specific on particular behaviour of small pieces of codes only.
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?
   This will determine the integrity of the newly updated piece of code whether it still perform in similar manner as the previous version, thus maintaining the behaviour of the overall source code that is dependent on the outputs of the tested / refactored units.
3. How does Unit Testing help the bottom-up testing approach?
   As discussed above, this is testing smaller parts of a source code before testing the sum of all parts in integrated manner.

• What is Unit Testing?
  Unit testing is utilized to test specific / individual parts of the code, it goes into testing modules, to test the smallest testable unit of development

• 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 makes it possible for the programmer to refactor code at a later date while making sure that the module is still working correctly. Unit testing after refactoring is important as it makes sure that no accidental changes in the behavior of the code have been created.

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

Unit testing makes sure that every component works and continues to work during development, updates and any further alternations. Writing the test procedures before the actual design of the program code can actually help with to structure the application itself
