Unit Testing - Reading Assignment

  1. What is Unit Testing?
    Testing smaller modules or compartments of a large 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 there could be unintended consequences that may not present itself on the surface.
  3. How does Unit Testing help the bottom-up testing approach?
    Testing the compartments or smallest building blocks and then the integration testing helps insure that problems may be caught in timely and acceptable manner before it snowballs into a bigger problem later on down the line

  1. What is Unit Testing?

Allows units or portions of the source code to be tested to determine if it’s ready to perform.

Because refactoring can always be done in the future.

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

You’re able to test units or parts of a program first and then test the sum of its parts to integration testing is simplified.

1;Unit testing is testing individual parts of the code to ensure they work.
2; Unit testing is important for refactoring since you can focus on just a small part of the code without worry of breaking it.
3: Unit testing helps the bottom up testing to see the source code work and then the entire application.

  1. It is testing the smaller components of a software individually or different source code individually
    2.As it permit the developer to have tests ready to test each function therefore allowing the identification of eventual problem in the source code
    3.It allows the identification of eventual problem at the beginning so the application can be up and running and not revisited multiple number of time before it is functional

  1. A unit test tests the functionality of individual units of source code.
  2. Individual units isolate where refactoring is required. Whenever a change causes a fault it can be identified and fixed.
  3. Unit testing from the bottom-up ensures the integrity of the lower hierarchy elements, positively affecting the components that rely upon them.

1- unit testing is about isolating each part of a program (code) and show that the individual parts are correct
2- It is impprtant because it allows to introduce changes in the program in advanced stages and still assure that the programm works properly
3- Because by testing the lower units of the program first in some way assures that the next upper level works too.

1.)
In computer programming, 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, 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.)
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- It is a method in which individual parts of the code are tested in order to know if they are ready to use.
2- To have a high degree of certainty that the unit works properly.
3- It is more efficient finding the problem at the specific unit that is happening.

  1. Unit tests are usualy created by programmers and it is meant to test each individual unit of source code is tested to determine if they are fit for use. Unit is the smallest testable part of an app.

  2. Because we need to ensure an “app” will work fine without errors like before update.

  3. Unit testing is needed because with integration test you won’t know where the errors are coming from unlike with where you know exactly where they are when doing unit testing/testing seperate parts individualy.

  1. What is Unit Testing?
    It means testing the smallest possible part of a program in isolation in order to ensure it is working correctly.

  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 the unit tests can be run while and after refactoring to catch bugs early and verify that the refactoring didn’t break anything in the application.

  3. How does Unit Testing help the bottom-up testing approach?
    It makes the developers trust in the units. And it makes integration testing easier.

    The best way to refactor is to do it in small steps. Unit testing means testing the smallest test-possible pieces/sections of code. Code refactoring should not change anything about how the product behaves so the less you change/refactor at once, the better.

  3. How does Unit Testing help the bottom-up testing approach?
    Bottom - up testing is an approach to integrated testing where the lowest level components are tested first, then used to facilitate the testing of higher level components. By testing the parts of a program first and then testing the sum of its parts, integration testing becomes much easier.

1: unit testing is testing the code itself and the individual parts.

2: To make sure your code still works as it was before without errors as it was beforehand.

3: It helps simplify integration. seeing how the programs work beforehand can give you a clear guide if something goes wrong later.

Refactoring still leaves the possibility for game-breaking errors. Unit Testing is the priority in order to prevent crashes.

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

Because testing each and every bit of the system reduces uncertainty.

  1. Unit Testing is a procedure to test that all individual source codes are fit for use. they are run by software developers to ensure that code meets is design and behaves as intended.
  2. unit testing is important for refactoring to make it easy for the programmer to check whether the piece of code is still working properly.
  3. Unit testing helps the bottom-up testing approach by testing part of of a program first, then the sum of the parts so integration becomes easier.

  1. Testing (new) parts of the code separately
  2. If the new parts (units) of the code are tested then it is possible to upgrade without altering the user experience
    3 the best way unit testing helps is that it documents the code changes

    First, a unit is the smallest testable part of an application. Unit testing is done on individual units to determine if they are fit for use. The goals is to ensure the code meets design and behavior intent.

    Unit testing also provides a sort of living documentation of the system and this can be a great reference to have for future upgrades/changes/modifications or to spur ideas for different projects.

  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 still need to ensure all units/modules work correctly. You would begin by write test cases for all functions/methods so that when a change results in a fault or bug, it can quickly be identified and readily corrected.

  3. How does Unit Testing help the bottom-up testing approach?
    Integration becomes easier and faster because you are testing the parts of the program first and then testing the sum of the parts.

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 assures that the code still works after the refactoring. Automatic unit testing makes it easy to identify faults caused by a change in the code.

  3. How does Unit Testing help the bottom-up testing approach?
    Because every unit ist tested itselft before testing the integrated units.
