Question 1

The principle of early testing is sometimes referred to as s… because it is an approach where testing is performed “ “ in the “S…”.

Answer 1

shift left
earlier
SDLC.

Question 2

Shift left basically suggests that testing should be done “e…” (e.g. not waiting for code to be “ “ or for “c…” to be “ “), but it doesn’t mean that testing later in the “S…” should be “ “.

Answer 2

earlier
implemented
components
integrated
SDLC
neglected

Question 3

There are some good practices that illustrate how to achieve a “shift left” in testing, which include:
