A unit is the smallest testable part -
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?
Even if one unit works does not mean that the system as a whole works. It makes it possible to implement on later date. -
How does Unit Testing help the bottom-up testing approach?
If you know that the small parts work on their own it is easier to find more systematic errors on a bigger picture

Individual units of Source Code that are tested to determine if they are fit for use. Unit tests are created by programmers or occasionally by white box testers. Each tesT case is independent from the others. Method stubs mock objects fake and test Hardnesses can be used to assist testing a module in isolation. They are written and run by software developers to ensure that code meets its design and behaves as intended. It can be manual or formalized.

Unit testing allows the programmer to refactor code at a later date, and make sure the module still works correctly in regression testing.
It can be later faulty and this makes it easier to find and fix at a later date.
- It’s reduces uncertainty. By testing the parts of a program first and then testing the sum of its parts, integration testing becomes much easier.

It is a method where you test pieces of source code to determine if they are fit for use. A unit is the smallest testable part of an application.

After a refactoring you need to make sure the new piece of code is running correctly. It makes it easier to identify errors in the code.

How does Unit Testing help the bottom-up testing approach? Creates small test cases first that can then be built upon when introducing more complex testing.

What is Unit Testing?
A method by which individual units (smallest testable parts, like function or procedure) of source code are tested. Examples of unit testing frameworks include open source solutions such as the various code-driven testing frameworks known collectively as xUnit, and proprietary/commercial solutions such as TBrun, Testwell CTA++ and VectorCAST/C++.
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?
Refactoring can help with improved code readability and reduced complexity, without changing its external behavior. Unit testing is important to make sure the modules work correctly with the refactored code.
How does Unit Testing help the bottom-up testing approach?
Unit testing with the bottom-up approach makes sure each unit of a program/app works properly by itself. This can prepare the team to then do integration testing and know that individual parts function properly.

It is important to perform unit tests because it allows to have efficiency when you need to check that no bugs or issues are being introduced to the codebase during the refactoring process.
- How does Unit Testing help the bottom-up testing approach?
Unit Testing helps because you can ensure from the beginning that all the individual pieces of software are functional and correct so that they are more likely to work well together.

This is a testing of the smallest part of an application or function/process(in procedural programming) to see if the source code is fit for use. -

Having tested the smallest part first before testing all the integral part uncertainty will be eliminated in each unit and thus help to simplify integration testing of the combine Units all together.

- You test if specific source code works
- Unit testing is the foundation. Refactoring is just trying to make shortcuts.
- Bottom-up testing always starts with specific Unit testing before you can ensure the protocol is working as a whole.

- This is a test of the functionality of the smallest possible parts of a program. This can be a procedure, function or similar.
- The procedure or function will execute a task. However this task can be executed in several ways. If we wish to make the execution as fast as possible, we might try different codes with the same intentions. We must now be able to verify if the output is identical and if the execution is faster, else we discard the “new code”. In order to verify we need unit testing.
- By assessing the functionality of the parts prior to the finished product you may find and debug more efficient. Assume you have a lego construction containing 10 pieces. If you evaluate the pieces prior to assembling, you are more probable to be successful in assembling the construction.

Also modifying code only to be executed in a faster way or more readable can cause errors. As unit testing makes it easier to find errors in the code more easily, it is important also for refactoring.

the definition of bottom-up testing (found here: https://www.tutorialspoint.com/software_testing_dictionary/bottom_up_testing.htm): “Each component at lower hierarchy is tested individually and then the components that rely upon these components are tested.”.
Seems like unit testing is a part (the solid basement) of the bottom-up testing approach.

Unit testing is important for refactoring because refactoring can be done after writing several tests, or after each test. It is the act of changing a piece of code without changing its functionality.

The main purpose of the bottom-up testing is to expose faults in the interactions between integrated units where individual units are combined and tested as groups.
