20. What is the significance of 'shift-left testing' in the software development life cycle?

Shift-left testing is irrelevant in the software development life cycle.

Shift-left testing involves testing code at the end of the development cycle.

Shift-left testing emphasizes early testing in the software development life cycle, detecting and addressing issues as early as possible.

Shift-left testing only applies to specific programming languages.
