Unit Testing - Reading Assignment

[CryptoDance]

1. What is Unit Testing?
   Unit testing is testing the code at the smallest level to make sure each function serves it’s purpose.
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 determines if a code still performs its function after refactoring.
3. How does Unit Testing help the bottom-up testing approach?
   Unit testing all the small components before assembling the machine increases the chances of finding any issues earlier and more efficiently. If you wait until it is all built, it may be more difficult to pinpoint the issue.

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

2. So developers ensure that the code in question meets its design and behaves as intended.

3. By testing individual units of the source code of a program first before testing the whole program. In this way, we can identify bugs faster and more efficient and effectively and tackle them before they become greater issues.
   Integration testing is much easier to do in this way too.

1. A way of testing so that the source code is fit to use

2. Because you want to make sure it’ll keep working

3. It helps integrating

• 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. A unit is the smallest testable part of an application. In procedural programming a unit may be an individual function or procedure.

• Refactoring means that you change and (hopefully) improve the internal structure of the code without changing the behaviour of the code.

It makes the program more efficient. It also helps with integration.

Integration testing becomes much easier.

1. Unit testing is the process of testing the smallest part of your application possible and making the changes to the final app. In procedural programming, a unit may be an individual function or procedure. Unit tests are created by programmers or occasionally by white box testers.
2. Unit testing is extremely important for refactoring because of the fact that making big changes while refactoring can mess up the large source code which can harm the app functionality.
3. It helps simplifiy integration. 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.

[Jaakko_K]

1. Unit testing is a method of testing the smallest individual testable parts of an applications aka units. Unit testing isolates each part of the program and tests that these individual parts are correct.

2. Refactored code can be tested with unit testing after the changes to the code are made to be sure that the unit or part of a program still works as it should.

3. Unit testing enables the bottom-up testing approach for that testing can begin from the smallest testable parts of a program and then move to testing the sum of these parts or a set of units.

[JasonM]

1. What is Unit Testing?
   This is the testing of a specific piece of code with a known expected result.

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 developers to identify issues across the code base for issues, straight after a change has been made.

3. How does Unit Testing help the bottom-up testing approach?
   This allows testing of the isolated functionality of an application, which will then be integrated to other units to ultimately form the final product. Unit testing allows granularity to isolate an issue before troubleshooting could be come complex and time consuming.

[TeknoMu]

1. What is Unit Testing?
   Unit testing refers to a methodology which test the single basic unit of programming. The basic unit corresponds to a 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?
   Because having a test case for each function (unit test) make it quicker to identify issues when changes are applied.
3. How does Unit Testing help the bottom-up testing approach?
   It helps because you test each unit first and the sum of the parts later it makes easier to identify issues

Unit Testing - Reading Assignment:

Q1: What is Unit Testing?
A: 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.

Q2: 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: Unit testing is important for refactoring as it allows the programmer to refactor code at a later date, and make sure that the module still works correctly.

Q3: How does Unit Testing help the bottom-up testing approach?
A: Unit testing helps the bottom-up approach by reducing uncertainty in the units themselves.

1. Unit testing is the process of testing individual units of source code to determine if they work effectively.
2. Unit testing allows the programmer to refactor code at a later date, and make sure the module still works correctly (e.g., in regression testing). 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.
   Readily-available unit tests make it easy for the programmer to check whether a piece of code is still working properly.
3. Unit testing reduces uncertainty and simplify the testing process.

[dsutter]

1. Unit testing is a method to test individual units of source code, and can be run automatically as a part of the build process.

2. Unit testing is important for refactoring, because it reduces the risk if a programmer decides to change how the code works (e.g. to make it more efficient), and it will help determine if the change still produces the expected results.

3. Unit testing helps the bottom-up testing approach because you are testing the smaller functional parts first to discover problems, and this makes integration testing easier.

[gravity]

1. A unit is the smallest functional part of a software. So a unit test is to test the individual units of the source code.
2. Because you need to make sure the code still performs as it should. Otherwise the whole programme will crash or will become unreliable.
3. With unit tests written for every unit of the programme, we can check “bottom up” all the parts of it from the smallest part up to the rest of the software.

[LukeS]

1. A method of testing where you test individual units of source code to see if they operate as designed.
2. unit testing after refactoring is necessary to make sure that the code not only runs as it should but to make sure it hasn’t affected how any other parts of the program run.
3. By testing units of code you can test each section before running the whole code, this allows errors to be found easier.

	○ 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. Unit tests are created by programmers or occasionally by white box testers.  The goal of unit testing is to isolate each part of the program and show that the individual parts are correct.[2] A unit test provides a strict, written contract that the piece of code must satisfy. As a result, it affords several benefits. Unit tests find problems early in the development cycle.

1. Unit testing is when you test the smallest testable unit of your code to see if it reacts as expected.
2. Unit testing is important for refactoring as it allows you to test just the part of the code you are changing to see if you get the expected result, it allows your to spot test parts of your code later on.
3. Unit testing assists the “bottom-up” approach to testing as it helps you isolate and more easily identify issues. rather then getting an error after testing a large section of code and not knowing where the issues is, testing the small sections of codes allows you to isolate the issue.

[Oliver73]

• What is Unit Testing?
  Unit testing is for testing individual parts of the code. Like testing a module, function; the smallest testable unit of a 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?
  To ensure it still works like before without errors

• How does Unit Testing help the bottom-up testing approach?
  Starting with an integration test without doing the unit test first can lead to complications as one does not know what part of a program an error is coming from.

[vegas316]

1. Unit Testing is the practice of building programmatic tests which supply specific inputs and specific outputs and then assert whether the function worked as expected. It is a practice which quickly can identify any new errors introduced to the code.
2. Refactoring code can introduce errors. Unit testing can quickly identify those errors so they can be corrected.
3. All program functionality is built upon different classes, methods, and functions. Unit testing ensures that the foundational components are working correctly, before they are assimilated into larger processes.

[bbss]

1. Unit Testing is the approach of writing tests for specific units of code.

2. Unit testing is important for refactoring, because by running the unit tests after the refactor you can be sure that you didn’t introduced bugs during refactoring.

3. Unit Testing tests the smallest components in a rigorous way.

[Denis_Petitclerc]

1. Unit testing is a method by which individual units of source code are tested to determine if they are fit for use and it’s the smallest testable part of an application.

2. In continuous unit testing environments, through the inherent practice of sustained maintenance, more importantly, unit tests will continue to accurately reflect the intended use of the executable and code in the face of any change.

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