  1. What is Unit Testing?
    Testing every singular part of an applications to isolate possible faults.
  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 that the app runs smother as before.
  3. How does Unit Testing help the bottom-up testing approach?
    It tests all the units singularly before doing an integration test.

1) What is Unit Testing?
Unit testing is when a computer program is tested in functional or procedural portions (units) fit 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?
Refactoring is a good method of making changes to the code. The method is meant to review to see which method of the reprogramming is a better fit for the overall programming project.

3) How does Unit Testing help the bottom-up testing approach?
This helps with the integration of the programming, the portions are tested and finding errors becomes easier in the overall testing phases or the project.

  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?
    Unit testing is important for refactoring because it ensures that all components of the code are working properly after a change has been implemented.
  3. How does Unit Testing help the bottom-up testing approach?
    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.

  1. What is Unit Testing?
    With unit testing, you test the functionality of the units themselves which results in testing the smallest parts of a code.

  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 with unit testing you go thru all the little units/parts of the code and check it step by step if everything is running if not you can change/tweak the little parts first if needed and work your way up to the bigger parts of the code.

  3. How does Unit Testing help the bottom-up testing approach?
    Because you go from testing one little part to testing a few little parts, to testing more few little parts. This way you integration testing becomes much easier.

  1. Unit testing is individual parts of a source code that are being tested to determine if they are fit for use.
    2.Whenever there’s change in source code, unit testing allows for bugs to be spotted in a particular part of the source code and quickly be fixed by the programmer.
    3.Before testing the source code all at once you are able to test parts to make sure they work. Reduces uncertainty of different parts.

  1. Unit testing is a method of testing individual units of source code in order to determine if they are fit for use.
  2. It is important for refracting because without it, a developer could change the source code and not realize that it is broken down the line. Hence the importance of unit testing.
  3. It helps it because it allows you to find individual sections fo the source code that may be broken

Reading Assignment: Unit Testing

  1. What is unit testing?
    It is the method by which individual units of source code are tested to determine if they are fit for use.
  2. Why is unit testing important for refactoring?
    Unit testing allows the programmer to refactor code later, and make sure the module still works correctly.
  3. How does unit testing help the bottom-up testing approach?
    It helps identifying and solving issues quicker in units before integration testing.

  1. A method used by software developers to test individual units of source code to determine if they’re a good fit.

  2. It is important because it allows the code to be tested after any implemented changes to ensure the effectiveness and security of the code.

  3. Unit testing provides an easier path for integration testing because the individual parts are looked at for any faults or defects beforehand.

  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. The goal of unit testing is to isolate each part of the program and show that the individual parts are correct

  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, 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.

  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.

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 allows you to re-test the same module once it has been refactored, at a later date - without having to rewrite the testing. The same testing works for the refactored code.

Unit Testing - Questions

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. 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. Each test case is independent of the others and substitutes like method stubs, mock objects, fakes, and test harnesses can be used to assist testing a module in isolation.”

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 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, 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, upstream and downstream impacts can be quickly identified and fixed.”

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

“It helps simplify 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.”

  1. Testing individual units of source code.
  2. It facilitates refactoring and ensures the code works
  3. By eliminating risk of the whole system not working, in unit testing we can just approach each unit of code separately and build bottom up.

  1. Unit testing is a method by which individual units of source code are tested to determine if they are fit for use, i.e. testing of new IS by parts.

  2. It allows to build IS and test them piece by piece logically, without having to alter or test the whole thing if something does not work or a new feature is created. It makes future development and testing more efficient, less complex, less resources are needed. It is a smarter way of doing things - piece by piece rather than huge chunks.

  3. It allows to test the first steps or basic components of a system, and then gradually test additional and extra features.

1. What is Unit Testing?
It is a method by which individual units of source code are tested to determine their fitness for 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 allows the programmer to quickly identify or isolate those functions or units that may have suffered a performance change as a result of the refactoring and attend to those units specifically rather than scouring the whole code

  1. How does Unit Testing help the bottom-up testing approach?**
    BY testing the parts of the code first and then testing the combined sum of all the parts (units), integration testing becomes easier. Unit testing also helps by providing a “living documentation” of the system and functionality of the code.

  1. What is Unit Testing?
    unit testing is for testing individuals parts of the code. Like testing a module, function: the smallest testable unit of a development.

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?
    From 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.
