# Testing

bazel test //speller/greeting:greeting-test

# Usually most convenient to see output errors inline
bazel test --test_output=errors '...'

# Keep an eye on test execution speed

# --cache_test_results=no

# Execute the output

# This works, but leaves the data file in the sandbox

# Query examples:

bazel query --notool_deps --noimplicit_deps "deps(//speller/main)" --output graph

# To explore interactively
# apt install graphviz xdot
# brew install graphviz xdot
# xdot <(bazel query --notool_deps --noimplicit_deps "deps(//speller/main)"  --output graph)

# Queries to consider:
# What files depend on external dep X?
# what files are referenced by the integration tests?
