Mocking not working when used with rayon::join #121
Description
Hello together,
with version 0.4.0 tests ran all fine when I mocked functions that were run in parallel with rayon.
With the update to 0.5.0 the same tests don't run any more.
Here is a code snippet that works with 0.4.0 but not with 0.5.0.
#![allow(unused)]
fn some_string() -> String {
"some test".into()
}
fn some_other_string() -> String {
"some other test".into()
}
fn join_both_function_with_rayon() -> (String, String) {
rayon::join(some_string, some_other_string)
}
#[cfg(test)]
mod tests {
use super::*;
use injectorpp::interface::injector::{CallCountVerifier, FuncPtr, InjectorPP};
#[test]
fn test_join_both_function() {
let mut injector = InjectorPP::new();
injector
.when_called(injectorpp::func!(fn (super::some_other_string)() -> String))
.will_execute(injectorpp::fake!(
func_type: fn() -> String,
returns: "test".into()
));
injector
.when_called(injectorpp::func!(fn (super::some_string)() -> String))
.will_execute(injectorpp::fake!(
func_type: fn() -> String,
returns: "test".into()
));
let var = join_both_function_with_rayon();
assert_eq!(var, ("test".to_string(), "test".to_string()));
}
}Steps to reproduce
cargo new injectorpp-test --lib; cd injectorpp-test
cargo add injectorpp rayon
// add snippet from above to lib.rs
cargo testErrors with version 0.5.0
