ICE when misusing test_case::test_case macro #134093
Description
I forgot the use test_case::test_case, and used the macro incorrectly. That got me an ICE:
Code
#[cfg(test)]
mod test {
type Result = std::result::Result<(), Box<dyn std::error::Error>>;
#[test_case(true, "ooops")]
#[tokio::test(flavor = "multi_thread", worker_threads = 1)]
async fn repro(_tracing: bool) -> Result {
Ok(())
}
}
fn main() {
println!("Hello, world!");
}With the following Cargo.toml file:
[package]
name = "repro-ice-2024-12"
version = "0.1.0"
edition = "2021"
[dev-dependencies]
test-case = "3.3.1"
tokio = { version = "1.42", features = ["full", "macros"] }Meta
