Unit Testing - Reading Assignment

1.What is Unit Testing?
It is the testing of individual units of source code to find functionality problems in order to make corrections and improvements…

  1. Why is unit testing important for refactoring?
    Because you can correct problems in small units ensuring with these tests that they do not alter other functions of the entire system.

3.How does Unit Testing help the bottom-up testing approach?
The parts are tested before their integration so that everything works correctly.

  1. What is Unit Testing?
    individual units of source code are tested to determine if they are suitable 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?
    To make sure the behavior of the code is not changed, and still works.

  3. How does Unit Testing help the bottom-up testing approach?
    By testing the parts of a program first and then testing the sum of its parts. More efficient at finding issues.

->It is way of development by creating a test for each small part of the project and make sure its works.

->To make sure that the change does not decrease or brake the function of the entire app or system.

3.How does Unit Testing help the bottom-up testing approach?**
->You make sure the small part works as it was planned and check the bigger structure after that. And this increases the efficiency of the production process.

1 The unit is the smallest executable part of a program; a procedure, a function etc. So the unit testing is an (exhaustive) testing (app) of the unit component. As you know what output a given input must render, you test the unit by feeding it with all possible inputs and if all is ok, all outputs are correct.
2 You may create bugs that affect different parts of the program. The larger the parts being tested the harder to debug the code. If you use unit testing you can almost run a new test after every line of code changed.
3. If all parts are ok, the probability of the whole working is better.

1 is used to test the source code
2 because when you are going to improve the structure of the source code it has already been tested, it did not make sense to improve the structure and test later
3 A developer writes a section of code in the application just to test the function. They would later comment out and finally remove the test code when the application is deployed.
A developer could also isolate the function to test it more rigorously. This is a more thorough unit testing practice that involves copy and paste of code to its own testing environment than its natural environment. Isolating the code helps in revealing unnecessary dependencies between the code being tested and other units or data spaces in the product. These dependencies can then be eliminated.
A coder generally uses a UnitTest Framework to develop automated test cases. Using an automation framework, the developer codes criteria into the test to verify the correctness of the code. During execution of the test cases, the framework logs failing test cases. Many frameworks will also automatically flag and report, in summary, these failed test cases. Depending on the severity of a failure, the framework may halt subsequent testing.

    Why is unit testing important for refactoring?

Answer:If you make a change during integration testing and something goes wrong (fault) you can more easily determine which unit is the problem if you have been unit testing.

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

Answer: 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 of by which certain units of source code are being tested to see if they are fit for use. Testing of separate elements of the source 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?

That it can be identified quickly and fixed. Unit testing is important since it allow developers to have ready-made tests for each function which can be easily identified quickly and fixed. If it not function, it is easy to identify and change in the source code.

  1. Unit testing is a method that software developers use to ensure the proper functionality of a certain part/module of code, and that such parts/modules are error-free.

  2. Unit testing benefits refactoring - improving code efficiency whilst keeping code functionality the same - as it lets developers know whether or not their code modifications have had an effect on the functionality of the code.

  3. Unit testing helps with bottom-up testing by testing each individual module when it is initially built. Then when other tests down the road are implemented, namely integration testing, it is less complicated to find future errors.

  1. Unit testing is testing small, individual pieces of code and seeing how it effects the overall application.
  2. Unit testing is important for refactoring because you want to see how the changes impacted the rest of the code in the application. You want to make sure the updates to the code didn’t cause any errors anywhere else in the application.
  3. Testing individual parts of the program first before testing the overall program. Starting from the bottom-up can identify exactly where errors occur more accurately.

  1. A unit is the smallest part of an app that can be tested. Therefore unit testing is testing individual units of source code to determine if they work or are in some way “broken”
  2. Every time you change one component of code, it could have negative consequences and influence the functionality of some other part of the code base that you didn’t account for. Therefore, any refactoring needs to be retested for use again.
  3. If yout test the individual units first, and then the sum of the parts, integration testing is easier (even though integration still involves human testing to some extent).

  • What is Unit Testing?
    Unit testing is a process by which individual units of source code are tested to determine if they are good for use.

  • 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 will allow developers to make changes to test software in different environments or circumstances to identify if it will perform under those circumstances.

  • How does Unit Testing help the bottom-up testing approach?
    Unit testing allows for testing of the individual components, which is integral in the bottoms up style of testing, which also seen i some circles as backward testing.

1.What is Unit Testing?
A method to test individual units (smallest testable application parts) of source code to determine if they work as expected.

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?
Since unit testing is implemented on the smallest testable parts on an application, faults caused by some change in the expected functions of the code can quickly be identified and fixed, without having to go through the entire application code.

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

  1. Unit testing a computer programming technique were each unit of code has specific test written for it to ensure it is functioning as expected.

  2. Unit testing is important in refactoring as it ensures that the components of the refactored code are still functioning as intended. Any bug in the code should cause one or multiple tests to fail highlighting the issue.

3.Unit Testing helps the bottom-up testing approach as it tests each component individually and independently prior to testing the solution as a whole.

Its easier to troubleshoot code back end, API and front end changes. Analogy is like building a house of cards, each layer in the program ecosystem has to keep working with as little rework in mind, otherwise the house of cards will keep crumbling which will require the build to start over.
3. How does Unit Testing help the bottom-up testing approach?
Test each program layer seperately then test the whole program together to ensure testing is complete and working upon any changes made.
