A system-on-a-chip (SoC) is an integrated circuit that combines multiple components, such as a microprocessor, memory, and I/O interfaces, onto a single chip. SoCs are used in many applications, such as smartphones, tablets, and embedded systems. Boxing Test-driven development (TDD) is a software development approach where developers write automated tests before writing the code. TDD can help to improve code quality, reduce the number of bugs, and improve development efficiency. Popular TDD platforms include JUnit, NUnit, and PHPUnit.
