# Run tests, upload the coverage report, and build bundles.
#
# We have to run a quick build (for the current platform only) before running
# tests because the tests rely on the agent bundle being available. We may need
# to switch this to a testing build (or add some custom build mode for singular
# cross-compilation) if we start invoking Docker from macOS with Linux
# containers. We don't want to do a full build to start with though because that
# can take a while.
#
# We run a few different testing cycles. The first is our primary test cycle for
# behavior and coverage reports. The second test cycle enables race detection,
# but we use a smaller synchronization root for integration tests in this case
# because the tests incur about an order-of-magnitude slowdown due to the race
# detector. The third test cycle (which occurs only on Linux and Windows) is for
# the 386 architecture (where race detection isn't available anyway).
#
# Finally, our build mode depends on what platform we're on. Only macOS is
# capable of building release bundles.

# TODO: We may want to add SSH teardown in here.
# HACK: We have to use a non-standard Codecov invocation because Bash on Windows
# doesn't seem to support process substitution, at least not on Travis.
# NOTE: This actually runs after before_deploy, but it's more logical to have it
# at this point in the file. See

# HACK: If we're doing a release deployment, convert the Windows bundles to zip
