The field of electronic testing has evolved significantly alongside the rapid advancements in electronics technology. Early electronic testing methods were rudimentary, primarily relying on manual inspection and basic measurements. As electronic devices became more complex, the need for sophisticated testing techniques grew exponentially.

Early Days (Pre-1950s):

• Manual Testing: Initial testing involved visual inspection and simple measurements using basic instruments like voltmeters and ammeters.
• Vacuum Tubes: Testing focused on the characteristics and performance of vacuum tubes, which were the primary active components in early electronic circuits.

Transistor Era (1950s-1960s):

• Transistor Testing: The introduction of transistors brought new challenges, requiring more precise measurements and characterization techniques.
• Automated Test Equipment (ATE): The first ATE systems were developed to automate repetitive testing tasks and improve efficiency.

Integrated Circuit (IC) Era (1970s-1980s):

• IC Testing: The advent of integrated circuits demanded more complex testing methodologies to verify the functionality and performance of these miniature devices.
• Functional Testing: Functional testing became prevalent, focusing on verifying the logical operation of ICs.
• Memory Testing: Specialized testing techniques were developed for memory devices, such as RAM and ROM.

VLSI and System-on-Chip (SoC) Era (1990s-Present):

• Advanced Testing Techniques: Very-large-scale integration (VLSI) and system-on-chip (SoC) technologies required advanced testing techniques, including built-in self-test (BIST) and scan-based testing.
• Boundary Scan: Boundary scan testing was introduced to improve the testability of complex circuit boards.
• High-Speed Testing: The increasing speed of electronic devices necessitated high-speed testing techniques and equipment.

Modern Trends:

• Artificial Intelligence (AI) in Testing: AI and machine learning are being used to optimize test processes, predict failures, and improve test coverage.
