Question

Respond to this paragraph with your own thoughts, only needs to be a few sentences:

Unit testing being shown through each step with "step 1: write logic" that the example from the video showed that "double calculateLoan" with float interestRate and int amount. Step 2: writing the tests with examples like "calculateLoan (2000,60,5.0)" with the result being 382.02. While for Test-Driven Development (TDD) Step 1 is to write out the tests first and then step 2 writing out the logic. Test-Driven Development allows to combine both building and testing together it mainly focuses on iterative development cycle where emphasis is on a written test case before any actual function is written in. All the steps together in TDD are adding a test, running the test and seeing if tests failed, writing in some code, run tests/code, and repeat from the first step. For Unit testing is the process of the smallest testable part of an application (units) and are independently placed in proper operation. When performing unit testing the user will write out a piece of code and continue to verify that piece of code by testing over and over again until it is correct. Unit testing comes in two different types: automation and manual. Both types are used on different components of the system that is being tested.

Answer 1

Unit Testing and Test-Driven Development (TDD) are methodologies used to ensure software quality. Unit Testing involves testing written code, while TDD begins with test creation before developing the code. The iterative process of testing and refinement enhances the final software design.

Step-by-step explanation:

The paragraph you've provided discusses two methodologies for ensuring that software functions correctly: Unit Testing and Test-Driven Development (TDD). In Unit Testing, the typical approach is to write the logic first and then create tests to check that the code works as intended. Conversely, TDD reverses this order, emphasizing the creation of tests before writing the actual code. The TDD cycle involves an iterative process where the developer writes a test, runs it (expecting it to fail), writes the code to make the test pass, and then refines the code while repetitively running tests. Ultimately, both approaches aim to deliver high-quality software by catching bugs early in the development process. Unit Testing can be either automated or manual and targets the smallest testable parts of an application. The process of testing and refinement is crucial, as it helps to unearth design issues and improve the overall software design based on the test outcomes.
