`-p package_name` not working as it tests all packages

[gitmalong]

Hi!

I tried the following commands to make tarpaulin only test a certain package of my workspace.

• cargo tarpaulin --skip-clean -p myapp-import --workspace
• cargo tarpaulin --skip-clean -p myapp-import
• cd import && cargo tarpaulin --skip-clean -p myapp-import --exclude-files ../*

Output:

user@Air-von-user myapp % cargo tarpaulin --skip-clean -p myapp-import --workspace

i think maybe try

cargo tarpaulin --skip-clean -- -p myapp-import

[xd009642]

So I've tested out cargo tarpaulin --skip-clean -p myapp-import with a project with your configuration and it works fine. Maybe check for something like a tarpaulin.config that may interfere or rerun and report back if it's still an issue.

--workspace will always cause all tests in a workspace to be ran so you don't want that! Also, if your workspace crate uses other crates in the workspace as dependencies you may see them pop up in results but it still shouldn't run their tests.
