What is shift-left testing?
In short
Shift-left testing moves testing earlier in the development lifecycle — into design, code review and CI — so defects are caught before they cost money.
Short answer
Shift-left testing moves testing earlier in the development lifecycle — into design, code review and CI — so defects are caught before they cost money.
What this actually means in practice
Practical shift-left: contract tests on every PR, security scans in CI, fast E2E on critical journeys, accessibility checks pre-merge. The point is shorter feedback loops, not 'more testing'.
The most common pitfall
Shifting left without shrinking the suite — and getting a 90-minute PR pipeline nobody waits for.
What to do next
Time your PR pipeline and trim every step that doesn't earn its place.
