This property describes the cost of a test. 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.
