Run additional tests using function flag for “load test”

Question

I have some tests that I would like to ignore when using cargo testand run only when the function flag is explicitly skipped. I know this can be done using #[ignore]and cargo test -- --ignored, but I would like to have several sets of ignored tests for other reasons.

I tried this:

#[test]
#[cfg_attr(not(feature = "online_tests"), ignore)]
fn get_github_sample() {}

This is ignored when I run cargo testas desired, but I cannot get it to work.

I tried several ways to launch Cargo, but the tests continue to be ignored:

cargo test --features "online_tests"

cargo test --all-features

Then I added a function definition to Cargo.toml this page , but they continue to be ignored.

Cargo. Cargo.toml .

Cargo.toml

[package]
name = "feature-tests"
version = "0.1.0"
authors = ["An Devloper <[e-mail]>"]

[features]
network = []
filesystem = []

[dependencies]

SRC/lib.rs

#[test]
#[cfg_attr(not(feature = "network"), ignore)]
fn network() {
    panic!("Touched the network");
}

#[test]
#[cfg_attr(not(feature = "filesystem"), ignore)]
fn filesystem() {
    panic!("Touched the filesystem");
}

$ cargo test

running 2 tests
test filesystem ... ignored
test network ... ignored

$ cargo test --features network

running 2 tests
test filesystem ... ignored
test network ... FAILED

$ cargo test --features filesystem

running 2 tests
test network ... ignored
