# 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).
