Usage

To query for code coverage, specify an Apex class, test class, or both. 

The returned JSON or XML object will contain two lists of integers: one for covered and one for uncovered lines.

The following example SOQL query retrieves code coverage results for a specific class or trigger covered by a specific test class:

SELECT Coverage

FROM ApexCodeCoverage 

WHERE ApexClassOrTrigger = ‘01pd0000000xxxx’ 

AND ApexTestClass = ‘01pD0000000xxxx’

For per-class code coverage, the query would be:

SELECT Coverage

FROM ApexCodeCoverage 

WHERE ApexClassOrTrigger = ‘01pd0000000xxxx’
