How can I specify a different default target for building and testing in the Cargo config?

I'm cross-compiling a Rust bare metal application for AArch64 target and I need to run unit tests on x86_64 target (my PC).

I created the file .cargo/config:

[build]
target = "aarch64-unknown-none"

I'd like to build for AArch64 but to run the tests for x86_64. If I change the build to x86_64-unknown-linux-gnu then the tests compile and execute. Is there a section where I could specify this? I have to swap these manually now.

I checked cargo guide but found no reference about test configuration.

You can achieve similar functionality by creating an alias in your .cargo/config file

[alias]
test_pc = "test --target=x86_64-unknown-linux-gnu"

then, you just just call

cargo test_pc

You cannot.

According to issue#6874, cargo doesn't have the feature to specify different target for cargo test.

FYI: you might have another solution for this issue if you use nightly, though I haven't made it work. The following links are about custom test framework, the issue opener says 'the solution'.
