Unit Testing - Reading Assignment

[Big_G]

1. What is Unit Testing?
   Unit Testing is 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?
   Because it allows for programmers to refactor code at a later date and make sure te module still works correctly.
3. How does Unit Testing help the bottom-up testing approach?
   It reduces uncertainty in the Units themselves.

[a.l.a.i.n]

1. Unit testing refers to testing smallest
   parts of applications e.g. single
   Functions. It verifies that every
   individual part works correctly.
2. Continuous unit testing ensures that everything still works as intended after any change that occurs
3. It simplifies integration by reducing uncertainty in the single units.

1. Unit testing enables the developer(s) to break down the search for glitches or errors to smaller
   manageable components to more accurately isolate the problems.

2. The benefits are to make sure the refactoring was successful in eliminating the errors and not
   introducing any other errors. In some circumstances it may be preferable to refactor the error later
   to avoid introducing unforseen problems elsewhere in the application ( although I didn’t really get
   this logic, if there was a possibility of fixing one problem but causing another, I would want to know
   immediately)

3. By unit testing each component, and being confident each section is clear of bugs you increase
   the probability that the intergrated test will be successful or at least have less errors.

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 important for refactoring because it allows the coders to have ready made tests for each function. This helps identify issues and make changes n the source code quicker.

3/ By testing the parts of a program first and then testing the total of all the parts, issues are quickly identified and corrected before they become large issues.

What is Unit Testing?

It’s the process of testing parts of source code in other to validate its operationality and efficacy.

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 parts of the entire code be tested and when a change shows an error, it can easily be identified and fixed, keeping the integrity of the other parts of the code.

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

Unit Testing prompts to full integration of the code to run smoothly and efficiently.

[BittMark]

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

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. 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 is 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 developer to refactor the code at a later code and still make sure that the new module works correctly. If something doesn’t work correctly anymore, then the piece causing the fault c can be easily identified.

3. How does Unit Testing help the bottom-up testing approach?
   Unit Testing helps the “bottom-up” testing approach by testing the parts of the program first, and then testing the sum of them, which finally makes integration testing easier.

[Rickspider]

1. Testing code down to its smallest possible parts. Like cogs in a machine.

2. Because you get to test every “moving part” individually without breaking the whole structure, so you’ll know what change has modified the behaviour of your program and what change has made it more efficient.

3. In the same way it helps code be more efficient: You get to improve every single part of code without messing with the overall structure. You’d find an error early on and you’ll know exactly which part of your code is giving you trouble.

[ShreyPanda]

1. What is Unit Testing?
   Unit testing is a method used to test individual pieces of code to determine if it performs as intended.

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 would be essential to refactoring as it allows the developers to ensure that after the adjustment was made, that the rest of the code still functions as intended (more efficiently) without any errors.

3. How does Unit Testing help the bottom-up testing approach?
   Bottom up testing is a process by which parts of the program are tested first, followed by the entire program to ensure less uncertainty, allows the developers to spot errors easily and allow for better integration.

[Selim]

hi everyone,

1. Testing individual units separately to check they work correctly.
2. That enables to check you got the benefit of your change without adding any new error or changing the behaviour of the code
3. It makes sense to test the individual parts separately before the sum. If you check the sum first and see it does not work: you don’t know if it is due to an individual unit having an issue or if it is due to the way you put the units together.

[Mroman]

1. It is method by testing individual source of code, to see if they run without errors.
2. To make sure the change that we have done is working properly, does not affect other parts.
3. It simlpify the task, by unit testing it can easily identify the single parts or functions not working. Once unit testing is sucessfull run an integration testing to prove all parts work together.

[gunnarseay]

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” in software testing refers to the smallest testable part of an application.
2.) Unit testing is important for refactoring because it ensures that the base code isn’t affected and testing classes don’t become mixed. In addition, unit testing will help refactoring by not changing the use case of the code/overall behavior; programmers can test individual pieces without affecting the code overall.
3.) Unit testing helps the bottom-up testing approach by making integration testing easier. Parts of a program can be tested first and then the sum of all those parts can be tested as a whole (units may reduce uncertainty in themselves in program creation).

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. It allows them to write test cases for functions and methods and if there is an issue within a certain part of the code it’s easy to go back and determine what caused the issue and fix it.
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.

[DesireeC]

1 Is a test made from the smallest part of the code, to ensure it is working correct.

2 It is important to developers to execute unit testing because they can find easily any errors, and what they should be specifically improving.

3 Unit testing helps to simplify the process by reducing the possibilities of error on each code line.

• What is Unit Testing?
  Testing of a smallest part of source code (for example, function, procedure).

• 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 required to check the correct functioning of the code at later date, after new changes to the code to make sure they do not impact the original purpose of the code.

• How does Unit Testing help the bottom-up testing approach?
  Unit testing reassures that each component works as intended and if bugs occur dev can easily fix it; and move on to test bigger parts of source code.
