Class SamplingPerTestCoverage

java.lang.Object

com.atlassian.clover.recorder.BasePerTestCoverage

com.atlassian.clover.recorder.SamplingPerTestCoverage

All Implemented Interfaces:

PerTestCoverage, Serializable

public class SamplingPerTestCoverage
extends BasePerTestCoverage

This model of per-test coverage does not retain all coverage data in memory but rather keeps a reference to each per test coverage file on disk and loads on demand. A capacity LRU cache is used to reduce disk IO.

In order to maintain performance, it samples the first element (entry hit) of each method in each FileInfo for the tests that that hit it then groups this information at the file level. When coverage data for a range is requested, only the tests that hit the relelvent FileInfo are loaded and queried thus, in most situations, avoiding a full scan of all per-test coverage files for each query.
