It is beneficial to put Rust integration tests (those standalone tests in /tests
) folder into a single crate.
In other word, instead of doing
tests/
foo.rs
bar.rs
do
tests/
integration/
foo.rs
bar.rs
instead.
There are two advantage of that:
- Faster build time since Rust compiler don’t need to link for each individual test crates
- Fast run time since Rust can run all tests in parallel, but cargo can only run executables sequentially
