How Test-driven development or TDD works? Explained with examples
Test-driven development Test-driven development or TDD is a software development approach where tests are written before the code is even created. The process encourages simple designs and inspires confidence because developers know that their code meets the requirements defined by the tests. So the tests are written before the actual feature or functionality exists. This may sound a little backward, so I'll provide an example. How TDD works? Imagine a mobile app designed to enhance security for various services like banking or secure entry systems. It does this by adding a facial recognition feature to verify users. The test you write first would check to see if the app can accurately verify a user's identity using facial recognition. For example, the test might simulate submitting a user's photo and then checking to see if the app recognizes the person correctly or denies access if the face doesn't match the user's stored facial data.
