In which testing methodology are tests typically automated along with the development of the software?

The selected answer, which is Test-driven development (TDD), is indeed the correct choice because TDD is a software development approach where tests are written before the actual code. In this methodology, the process starts by defining a test for the functionality that needs to be developed. Once the test is created, the development team writes just enough code to make that test pass. This cycle of writing a test, implementing the minimum code required, and refactoring occurs repeatedly.

By automating the tests as they are being developed, TDD encourages maintaining a robust suite of automated tests that verify the functionality continuously. This leads to immediate feedback on the code, ensuring that any changes made during development do not break existing functionality. TDD not only supports the development of code but also enhances the quality of the software being built as tests become an integral part of the coding process.

In contrast, options like the test-first approach may refer to similar principles but are not necessarily tied to the rigid structure and cycle of TDD that emphasizes the automation of tests during the development phase. Test design specification is focused on the planning aspect of tests rather than their direct implementation alongside development. Lastly, test scripts refer to the scripts used to execute tests but do not relate to the methodology of
