Unit Testing - Reading Assignment

[REGO350]

1. Unit testing tests individual units of source code to determine that that they are functioning as expected (no bugs).

2. Unit testing tests cases for all functions and methods so that whenever refactoring causes a fault, it can quickly be identified and fixed.

3. In a bottom-up testing approach, unit testing reduce uncertainty in the unit themselves: by testing parts of a program first and then testing the whole program, integration testing becomes much easier.

1. What is Unit Testing?
   A: Unit Testing describes the 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?
   A: Because unit testing allows the programmer to refactor code at a later date while making sure the module keeps working correctly. This is achieved by writing test cases for all functions and methods so that whenever a change causes a fault, it can be quickly identified and fixed.

3. How does Unit Testing help the bottom-up testing approach?
   A: It helps since by testing the parts of a program first and then testing the sum of its parts, integration testing becomes much easier.
   Since the all does not equate simply to the sum of the parts, integration with peripheral units should be included in integration tests.

1. What is Unit Testing? Unit testing is a method where individual units (smallest testable part of an application) 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 automatically alerts the developer if their upgrade has caused any faults in the unit that stops its previous functionality
3. How does Unit Testing help the bottom-up testing approach? The integration of units that are known to be behaving correctly individually should be quicker and easier than testing the entire system as a whole.

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

1.) Unit testing is testing an individual parts of the code. Testing parts of the whole code, so you can eliminate errors and mistakes before making the whole project.
2.) To make sure the code works without errors.
3.) If you dont make single unit testing before doing an integration, if it comes to a problem you do not know where the problem is or could be coming from…

[Gutto13]

1: It is the most basic form of testing where individual units of source code are tested to make sure they function properly.
2: Because it allows the ability to quickly check code changes to see if they have any affect on the outcome of the functionality of the changed source code.
3: It helps bottom-up testing approach by providing a base test to ensure all individual source codes are functioning properly. From there you can work your way up to integration testing where you no longer have to worry about the individual code but more so how you are trying to make them all interreact together.

1. What is Unit Testing?

• 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 is important to see that whenever a change causes a fault, it can be quickly identified and fixed.

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

• Unit testing may reduce uncertainty in the units themselves by checking the parts first and after the sum of all parts. Like this you can work your way up to integration testing.

1. What is Unit Testing?

Unit Testing s 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 is important for refactoring as it allows 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. How does Unit Testing help the bottom-up testing approach?

Unit testing helps 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.

[TimInnes]

1. Unit testing is a method of testing individual separate modules or units of code to determine if it is fit for use. By isolating each part of the program through unit testing we can determine if a specific unit of code functions correctly.

2. It is important as it allows the refactoring process to be more efficient and safe by allowing isolated testing without effecting the function of the codebase as a whole.

3. By testing individual sections and functions of the program first and then testing the integration with the other sections, it allows a more efficient approach.

[smario]

1.A method of testing individual units of source code to make sure they are fit for use, which each unit is the smallest testable part, an individual function or procedure to assure that unit is performing to its potential
2. Unit testing is important for debugging and to locate problem in the code ,and be able to refactoring to be able to reuse and be able to develop other similar systems.
3. Its important do bottom-up testing so it makes it easier for integration and be ready for creation of an app.

[Croyden]

1. Unit testing is automated tests written and run by developers to ensure that a section of a unit/application meets its design and behaves as intended.

2. Unit testing is important for refactoring because it gives you a chance to test the code and see if it actually does what its suppose to do. If not unit testing provides the team with information that can better help these projects along with better code that produces better results.

3. It tests small bits of program/information at a time which allows to ensure all pieces run correctly before having to do full integration test

[Sung]

1. What is Unit Testing?
   Unit testing is a method where individual units of source code are tested to determine if they are ready 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 is important when refactoring because you want a quick and easy ‘ready made method’ to see if the changes have the desired effect.

3. How does Unit Testing help the bottom-up testing approach?
   Each unit of source code can be tested individually then in a later stage the sum of all parts can be tested. This rules out errors more efficiently in an earlier stage thus saving time.

• What is Unit Testing?
  A method to test the smallest parts of an application to determine if the application is ready to use.
• 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 the module which is refactored can quickly and easily be checked, which always happens afterwards, when the code already worked.
• 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.

1. Unit Testing tests all the smallest testable parts of an application
2. Unit Testing helps with refactoring because it ensures that the module still works correctly after the internal changes of the code
3. Unit Testing reduces uncertainty regarding the source of a problem when using the bottom-up testing style approach

[MatWu]

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 of an application.
2. Because you can look at units individually and assure that the respective code delivers the same outcome regardless of changes. Therewith at later stages even earlier coded units can be optimized individually.
3. Unit testing may reduce uncertainty in the units themselves by checking the parts first and after the sum of all parts. That way you can work your way up to integration testing.

[Fluffpinkkitten]

Unit Testing tests individual parts of the code to see if it operates correctly

Unit testing during refactoring means that the behaviour of the code SHOULD stay intact as each internal structure code has been tested individually

unit testing ensures each component works and therefore the end product should be correct

[MarcisB]

1. What is Unit Testing?

• A procedure where small units of code are tested separately. A unit is the smallest part of code that can be tested.

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?

• If unit testing has been done, you know that each unit separately works and changing other units won’t affect it.

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

• With unit testing done, we now know that every unit works and we can move on to testing larger parts; testing clusters of units to see how they work together.
