I would like to know how to run a subset of tests using tarpaulin.
https://github.com/xd009642/tarpaulin - The documentation lists one argument --tests but that doesn't really provide a usage.
Using cargo, one can run tests such as:
cargo test <test_prefix> -- --nocapture
I would like to know how we can achieve the same using tarpaulin.
The command line
cargo test <test_prefix> -- --nocapture
is actually the same as
cargo test -- <test_prefix> --nocapture
because Cargo has a special exception that if you are passing one argument that doesn't begin with - (usually a test filter), you don't need to bother writing -- too.
tarpaulin doesn't have that same special one-argument feature, but it does have -- <args> — so just use that.
cargo tarpaulin -- <test_prefix> --nocapture
Or perhaps the more conventional/universal ordering with options first
cargo tarpaulin -- --nocapture <test_prefix>
In general, all the options to tarpaulin go before the --, and all the options to the test binary (typically the built-in Rust test harness) go after it.
