Unit Testing - Reading Assignment

[R_G]

1. Unit testing is a method of testing individual unit of source code to see that it is working correctly.

2. Because unit testing ensure that ,after refactoring ,the code still runs without any errors.

3. By testing the parts of the code first and testing the sum of its parts, integration testing is much easier.

1.unit testing: is a method by which individual units of source code are tested to determine if they are fit for use.
2. to check if it works correctly after you made a change.
3.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.

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?
   Unit testing is important for establishing that the code the was refactored is having the same results as it did previously.

3. How does Unit Testing help the bottom-up testing approach?
   By knowing that the individual smaller parts of the program/App work you are more confident and usually greatly improves integration testing of the whole project.

1. a method by which individual units of source code are tested to determine if they are fit for use.
2. Unit testing manes sure that the code does the intended job after the code change.
3. Integration testing becomes easier when unit testing was done in the first place.

[Estefano_Debernardi]

1.- It is how a part of the source code is tested to determine if it is fit for use.
2.- Because it helps them see if the task has improvements or if the change has made soemthing else different.
3.- It helps simplify integration.

1. Unit testing is a programmable way of testing each component of an application in every state possible. Unit testing is initialised by preceding development by writing the function of each unit, and how it should behave. When the developer builds the application, they must make sure that the unit satisfies the behaviour set out in the testing documentation.

2. When changes are made to codebases, it is difficult to predict the flow-on effects of such changes across the application. Where there is a living unit-testing document about how each unit should operate, errors caused by refactoring will quickly alert the developer of behavioural changes across the application. The unit testing document will easily monitor behavioural changes where there shouldn’t be. If refactoring is successful, each unit test should pass without changes to the output. If refactoring fails, the unit testing document will efficiently locate a bug, and the developer may continue working to resolve them such that each unit test passes.

3. Unit testing tests will assure that each unit of an application behaves according to specified instructions. When a developer can be assured that each unit test passes without changes to output behaviour, it assists massively when testing for the sum of all parts. If an individual component does not behave correctly, then it’s highly unlikely that the sum of the parts will behave correctly. Usually, this will amplify bugs.

1 - Unit testing is testing the individual units of source code to ensure that the code behaves as designed/expected. This allows for bugs/issues to be identified prior to combining the “units” into the application.

2 - Unit testing helps identify areas for refactoring. Speed/performance testing at the unit level may identify areas for optimization. Unit testing also helps confirm that any changes to the code do not impact the output/desired behavior.

3 - Unit-testing is a bottoms up approach that has you test the pieces before testing the whole and the thought is that this will make integration tests easier as any issues with the individual components should have already been identified.

[Zenkic]

1.It is the individual testing of separate elements of source code with a view to finding problems in functionality.
2.it is to make sure the refactoring actually achieved its goal and that the code works better
3.Unit testing makes integration testing easier as each part on it’s own is tested before trying to connect pieces of code.

[blockchainbrain]

1. Testing individual units of code to see that they work. A unit can be just a procedure or a function.
2. Because code can cause bugs all over the place with unit testing you can stay on top of all bugs and fix them as soon as possible.
3. Because you are able to test all the parts so you make sure the parts work before you put them all together and test the whole thing.

1. Unit testing:

• is a computer programming method,
• individual units of source code are tested:
  • these are smallest testable parts of an application (e.g. a function)
• extracting units / isolating them is important to verify single functionality, identify bugs, that prevent proper functionality & the their sooner as possible correction / fix from the developers that developed them
• in simple words this is done to assess that the code is functioning down to the smallests piece as it should

2. Unit testing is important for refactoring as it facilitates change at a later date. Writing test cases procedure for all functions & methods is helpful in such a way that we can find exactly which change causes a certain malfunctioning that is due to be corrected.

3. Unit testing helps the bottom-up testing approach in such a way that it reduces uncertainty in the units themselves. Integration testing becomes much easier.

[Ryan_Jackson]

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 so that the programmer can upgrade the code in the future without effecting the functionality.

3. Unit testing helps the bottom-up testing approach by reducing uncertainty in the units themselves, and by testing the parts of a program first, then testing the sum of its parts, integration testing becomes easier.

[dazzles]

Unit testing tests small parts of code to check for problems and make sure its functioning properly.

It makes sure that all the code works, small changes in one code can change everything rendering everything useless this insures that any and all small changes don’t have any significant changes to the source code.

it will help find problems before they become problems, a more efficient way of working you don’t want to build a billion dollar fighter jet from scratch and find all the problems at the end of production when you try to fly it.

Unit testing is important for refactoring in order to facilitate changes to the code, simplify integration, and provide living documentation.

3. Unit Testing helps the bottom-up testing approach by embodying characteristics that are critical to the unit’s success.

• What is Unit Testing?
  Unit Testing is the process of testing every unit in the source code and determine if they fit their use case properly. A unit represents the smallest testable part of an app.

• 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 it might yield unwanted results after making the code run faster. For example, when refactoring a unit code to execute faster, its execution process might be changed and some parts might get executed first and yield unwanted results. Unit testing allows the dev to find these bugs quickly and thus be able to fix them.

• How does Unit Testing help the bottom-up testing approach?
  By testing each unit of code first, this would make it easier to test the whole application or program as a whole, and if something’s not working properly, it could be the code structure, but the dev would be sure that all of his codes function well because of unit testing.

1. What is Unit Testing? Unit Test is a method by which individual units (a unit is the smallest testable part of an application ) of source code are tested to determine if they are fit for use. Ensures that the code meets its design and behaves 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? Ensures that all units of the code remain functioning as intended after the refactoring

3. How does Unit Testing help the bottom-up testing approach? by testing the parts of the program first, and then the sum of its parts, one can more easily determine which part is not functioning as planned.

What is Unit Testing?

Unit testing represents a method of testing individual parts of the code, isolated and ideally independent from other parts. It is the most granular level of testing that can be made.

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 because it might find flaws and issues when running the code. For example, the entire code might be running faster, but some individual parts of the code might be running sooner than they should (or used to do) making the final result different to what it was.

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

Unit Testing helps the bottom-up testing approach by reducing the uncertainty in the units themselves; also, by testing the individual parts of a code first and then testing the sum of its parts, making integration testing easier.

[Lehigr2]

1. What is Unit Testing?
   Unit testing is a method of testing individual sections of code to see if they are useable for production.
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 helps identify the errors early and then the developer can come back to it and fix the changes.
3. How does Unit Testing help the bottom-up testing approach?
   Because you test the individual smaller parts first before you put it all together and test the whole application.

[deniselbs]

1. What is Unit Testing?
In a unit test, each individual unit of source code will be tested. A unit is the smallest testable part of an application. Unit tests find problems early in the development cycle.

Unit tests are typically written and run by software developers to ensure that code meets its design and behaves 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?
To make sure the module still works correctly. 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.

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.

Unit Testing - Reading Assignment Answers

1. A unit is the smallest testable part of your application, by isolating and testing each unit of the program we can assert that individual parts are working correctly using a strict, written code for each unit that each unit must satisfy.

2. Unit testing is important for refactoring because it allows us to write test cases for each unit’s functions and methods so that if any breaking changes occur as a result of our refactoring these errors can quickly be identified, and fixed. While also alerting the developer who contributed the implementation.

3. Because testing each unit of the program first and then testing the sum of its units, allows for much easier integration testing.

[Nathan_Burkiewicz]

1. What is Unit Testing?
   Unit testing is a method used to test the individual code modules that make up a program or application to ensure they work 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?
   Unit testing is important when refactoring because it ensures that the internal changes made to the code do not affect the output and/or specified behaviour of the code. Refactoring code that has unit tests is easier and safer because the tests provide immediate feedback to the developers.

3. How does Unit Testing help the bottom-up testing approach?
   Unit testing helps the bottom-up testing approach since ensuring that the indiviual units of code work as expected simplifies the integration testing of the entire application or program - the sum of the units.
