When parallel testing is +enabled, tests in the test set will be run in descending order of cost. +Projects can explicitly define the cost of a test by setting this property +to a floating point value. + +When the cost of a test is not defined by the project, +:manual:`ctest <ctest(1)>` will initially use a default cost of ``0``. +It computes a weighted average of the cost each time a test is run and +uses that as an improved estimate of the cost for the next run. The more +a test is re-run in the same build directory, the more representative the +cost should become. |
