  1. A method by which individual units of source code are revised to see if they fit the use case.
  2. This is because if a change to the code causes a fault, it can be quickly identified and fixed.
  3. Testing source code units and then testing the sum of the parts that make the application, integration test can become easier.

  1. What is Unit Testing?
    Ability to test a unit of code designed to perform one particular action or set of actions
  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 ensure that the change in the code does not negatively affect how it works for the user/client
  3. How does Unit Testing help the bottom-up testing approach?
    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

  1. coded test-apps for the smallest component of the application to make sure that those parts look fine and work correct
    2)thanks to all the unit-test apps, it is easier and quicker to identify, if and where a new code-element causes problems
    3)because the single components of the application are first tested and then the sum; like if you construct a car, you first test breaks, motor, steering-functions and don’t build all and try do test-drive the whole car immediately/first without knowing, if the single parts work as they should

  1. What is Unit Testing?
    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 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?
    A: it helps find problems early in the deveolpment cycle and fix them. easy for the programmer to check whether a piece of code is still working properly

  3. How does Unit Testing help the bottom-up testing approach?
    A: it helps to make sure any mistakes that may occur are taken care of, helps with intergration and allows you to see the whole project before it goes to the client

  1. Running a test program, in isolation of the rest of the code, for each of the smallest testable parts of tan application to see if that part of the code acts how it should or returns the correct and required result.

  2. Unit testing allows refactoring easier, quality controlled and quicker because the result of the change can be immediately tested (against the original test program) to see if the same correct output is still achieved and that the code didn’t effect anything else in that unit.

  3. Unit testing helps bottom-up testing by picking up bugs early in the development cycle and this modular approach to testing typically also isolates bugs in one unit, making it easier and quicker to Find and fix , when debugging. In turn integration testing later in overall will make things easier and more predictable.

1- is a method by which individual units of source code are tested to determine if they are fit for use.
2- To ensure the refactoring actually works without any errors
3- By testing parts of a program first then test the sum of the parts it makes it easier for integration testing.

  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 allows the programmer to refactor code at a later date, making 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. Unit testing may reduce uncertainty in the units themselves and can be used in a bottom-up testing style approach. Testing the parts of a program first and then testing the sum of its elements makes integration testing easier.

  1. What is Unit Testing? It’s when you test small unit of code. Ideally during unit testing one documents expected rules prior to running the test. After the test is executed one should document the results and compare.
  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? - You should be able to repeat unit test even after refactoring and the same results.
  3. How does Unit Testing help the bottom-up testing approach? It reduces uncertainty going into integration testing. Because you’ve tested and hopefully document subsystems during the unit test.

  1. Unit testing is a way to test individual units of code to see if they are accurate, and functioning in the way that they should.

  2. Unit testing allows the programmer to refactor code at a later date, and 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. It helps because first individual units of the code is being tested, and then, those units are tested together as a collective. This is a much more efficient way of doing things.

1 What is Unit Testing?
Unit testing allows for bugs or any problems to be identified early on in the development cycle of a software application and provides developers with a detailed documentation of the application.

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?
Bug fixes can be found quickly and refactor code at a later date.

3 How does Unit Testing help the bottom-up testing approach?
Unit testing helps the bottom-up testing as it tests the parts of a program and then the sum of those parts leading to thorough testing and detailed documentation.

  1. Unit Testing makes sure that units of source code are tested to see if they are a good fit to use and they are created by programmers.

  2. Unit testing allows the programmer to refactor code anytime and make sure the module still works correctly (no bugs or problems). The approach is creating test cases for all functions and methods so that a problem can be quickly identified and solved.

  3. The Bottom-up approach helps testing the parts of a program first and then testing the sum of its parts, integration testing becomes much easier.

  1. The Unit Testing is a method required to assess the units of a source code whether its fit for use in Server app, API app and Clients app.
  2. It is important to unit refactoring in terms of managing any fault caused by changes in the code to immediately identify and fix. Makes it easier for programmer to check code whether is worked properly.
  3. It helps the bottom-up testing style to test some of the program parts first, review if input components and output are correct, before testing as a group known as integration testing.

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 each unit is the smallest testable part… each unit test is done separately and independently making problems to be easily located and up to the minute accuracy can be maintained.
3.How does Unit Testing help the bottom-up testing approach?
by being able to test the units (parts of the program) first and then testing the sum of its parts, making integration testing easier

  1. Unit Testing is testing of the smallest executable unit of code or development e.g. a function, a routine and is normally done by the developer to ensure that the unit conforms with the design specification and generates the expected output
  2. This unit testing after refactoring enables the developer (development team) ensure that the singular unit isolated from all other units still outputs the expected result with no new error introduced solely by it. It does not necessitate testing all other units
  3. Unit testing helps the Bottom Up testing approach by ensuring the first all individual sub components are working as expected prior to integration and integration testing thus making it easier to isolate problematic spots during integration testing and reducing time of for resolution. This approach also helps makes resolution and regression testing easier because the each function is typically developed as a unit.
