I'm trying to run my tests with nightly Rust using Windows Powershell. I run cargo test in the directory, and I get

Compiling rustcraft v0.1.0 (file:///C:/Users/Phoenix/Desktop/Rust/rustcraft)
error[E0554]: #![feature] may not be used on the stable release channel
 --> C:\Users\Phoenix\Desktop\Rust\rustcraft\src\main.rs:1:1
  |
1 | #![feature(integer_atomics)]
  | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^

error[E0554]: #![feature] may not be used on the stable release channel
 --> C:\Users\Phoenix\Desktop\Rust\rustcraft\src\main.rs:2:1
  |
2 | #![feature(collections)]
  | ^^^^^^^^^^^^^^^^^^^^^^^^

Obviously, I have to tell Cargo to compile it on the nightly channel, but how? I can't find any reference to specifying a channel in the help section, or any website I've found.

The command line solution may help you to configure your IDE: 

cargo +nightly test

Provided, of course, that you have the nightly channel installed. If not, perhaps install it with rustup install nightly (no need to switch to it, but check you're still on stable: rustup show).
