What's Wrong?

When asking claude code web to do something like 'add a new feature in rust, and make sure all unittests are passed', then claude code tries to add new codes, fixes bug with cargo build, and runs cargo test for testing.
And when trying cargo test with bash tool, for some reason, it just stucks and do nothing (and nothing change forever until I interrupt the bash tool via 'stop' button)..

What Should Happen?

The bash tool should be able to run the cargo test command properly, and should print out output messages even when all unittests fail.
