Class MaxCore

java.lang.Object
  extended by org.junit.experimental.max.MaxCore

public class MaxCore
extends Object

A replacement for JUnitCore, which keeps track of runtime and failure history, and reorders tests to maximize the chances that a failing test occurs early in the test run. The rules for sorting are:

  1. Never-run tests first, in arbitrary order
  2. Group remaining tests by the date at which they most recently failed.
  3. Sort groups such that the most recent failure date is first, and never-failing tests are at the end.
  4. Within a group, run the fastest tests first.
