when cargo test is run, it creates five binaries as we can see in target/debug/deps directory.
In addition to the src binary target/debug/deps/meow, we can see four more binaries, which are test binaries:
- unit tests ---> target/debug/deps/meow-ea5c5b8b2cf3b544
- tests/foo.rs ---> target/debug/deps/foo-8706df6ba36b6e2f
