EQS - Early Quality Score
Beyond Coverage: The New Standard for Real Test Quality
Software is accelerating — especially with AI-generated code.
Coverage shows what ran. EQS shows what works.
A unified metric for real test quality in human- and AI-generated code.
Why Test Coverage Isn’t Enough
Coverage ≠ Quality
What EQS Measures
Code Coverage
How much of the code tests execute
Mutation Score
How well tests catch real faults
Method-Scope Coverage (Early’s metric)
How many public methods have full, direct test coverage
A Real Example From Our Backend
We applied EQS to one of our backend files.
Before: only 2 out of 6 methods had tests (Method-scope is 2/6 = 33%
After: adding tests for the additional 4 methods.
EQS reached 100%

How Early Uses EQS
We use EQS to validate and benchmark our technology in a normalized way.
It’s how we measure the quality of tests our autonomous agent generates.
Why Engineering Leaders Choose Early
As Al and autonomous agents generate more of your code and tests, you need to know:
- Are these tests good?
- Do they catch real bugs?
- Which methods remain untested?
- Where should agents focus next?
