Build ignores problems in test modules

Environment

• org.rust.lang (0.4.183.5026-222)

• Rust toolchain version:

• rustc 1.67.0-nightly (b833ad56f 2022-11-18)

• IDE name and version:

• GoLand 2022.2.4

• Operating system:

• Linux 5.4.0-128-generic #144-Ubuntu x86_64 x86_64 x86_64 GNU/Linux

Problem description

• How to get build to show errors in test modules?
• CTRL+F9 seems to only build & show issues for "non-test" modules

Steps to reproduce

1. create 1 rust file with a any syntax bug in a test module (eg. referenced an non-existent identifier)
2. IDE should show red underline to indicate the problem
3. close that file (imagine you have hundreds of *.rs files and don't know where the issue is)
4. run cargo build, it passes (correctly)
5. run cargo test, it fails (correctly)
6. use rust plugin to build (CTRL+F9), it passes (somewhat correctly, but not helpful)
7. Open Problems view, no errors appear

Is there a way to get "build" to show problems in test modules?

What command (highlighted line) does the plugin show when performing a build in your case?

Here's an MWE:

in main.rs

mod erase;

fn main() {
    println!("hi");
}

in erase.rs (same directory as main.rs)

struct A {}

#[cfg(test)]
mod tests {
    use super::*;

    #[test]
    fn foo() {
        nothing; // <-- this is not defined anywhere, so fails on cargo test, but succeeds on cargo build
    }
}

Console output after CTRL+F9:

/home/wcarmon/.cargo/bin/cargo build --message-format=json-diagnostic-rendered-ansi --color=always --bin my-project --manifest-path /path/to/my-project/Cargo.toml
   Compiling my-project v0.0.1 (/path/to/my-project)
    Finished dev [unoptimized + debuginfo] target(s) in 0.51s
Process finished with exit code 0

it looks like your build command runs cargo build with --all and --all-targets. How do I get that behavior for CTRL+F9?
