load_workspace_at() looks at parent directories. If rust-analyzer is
in a directory (e.g. a monorepo) where a parent directory contains a
rust-project.json, that configuration wins over the Cargo.toml and the
test fails.
One easy way of testing this is deliberately writing an invalid JSON
file to the parent directory.
```
$ echo '{' > ../rust-project.json
$ cargo t -p load-cargo
---- tests::test_loading_rust_analyzer stdout ----
thread 'tests::test_loading_rust_analyzer' (38576150) panicked at crates/load-cargo/src/lib.rs:756:81:
called `Result::unwrap()` on an `Err` value: Failed to load the project at /Users/wilfred/src/rust-project.json
Caused by:
0: Failed to deserialize json file /Users/wilfred/src/rust-project.json
1: EOF while parsing an object at line 2 column 0
```
Instead, explicitly load the cargo workspace so the presence of a
rust-project.json never changes the result of the test.
