Methodology
This ranking is based on an independent evaluation of global QA-focused vendors using transparent, verifiable criteria. The goal was to identify companies where software testing is the core business, not an add-on service, and whose performance is validated by real client outcomes.
1. Vendor selection criteria
Only companies meeting all of the following were considered:
QA and software testing as a primary service line
Independent service provider (not a product/tool company)
Minimum team size of ~40+ QA engineers
Global or nearshore delivery capability
Public client reviews and documented case studies
Demonstrated long-term service reliability
2. Review & reputation analysis
Public, verified client feedback was analyzed across:
Clutch
G2
GoodFirms
Trustpilot
Gartner Peer Insights (when applicable)
For each vendor, we assessed:
Average rating
Number of verified reviews
Quality and specificity of feedback
Recurring client praise and recurring complaints
Presence of enterprise or high-complexity engagements
Direct quotes illustrating sentiment and delivery quality
3. Technical & delivery maturity
