# Tests the build step timing facilities.

# TODO: Missing tests:
# 1. 'time' target with a source target representing more than one virtual
#    target. This happens in practice, e.g. when using the time rule on a msvc
#    exe target whose generator actually constructs an EXE and a PDB target.
#    When this is done - only the main virtual target's constructing action
#    should be timed.
# 2. 'time' target with a source target representing a virtual target that
#    actually gets built by multiple actions run in sequence. In that case a
#    separate timing result should be reported for each of those actions. This
#    happens in practice, e.g. when using the time rule on a msvc exe target
#    which first gets created as a result of some link action and then its
#    manifest gets embedded inside it as a resource using a separate action
#    (assuming an appropriate property has been set for this target - see the
#    msvc module for details).
