问题描述
我有一些在使用 cargo test
时想忽略的测试,并且仅在显式传递功能标志时运行.我知道这可以通过使用 #[ignore]
和 cargo test -- --ignored
来完成,但由于其他原因我想要多组被忽略的测试.
I have some tests that I would like to ignore when using cargo test
and only run when explicitly passed a feature flag. I know this can be done by using #[ignore]
and cargo test -- --ignored
, but I'd like to have multiple sets of ignored tests for other reasons.
我已经试过了:
#[test]
#[cfg_attr(not(feature = "online_tests"), ignore)]
fn get_github_sample() {}
当我根据需要运行 cargo test
时,这会被忽略,但我无法让它运行.
This is ignored when I run cargo test
as desired, but I can't get it to run.
我尝试了多种运行 Cargo 的方法,但测试仍然被忽略:
I have tried multiple ways of running Cargo but the tests continue to be ignored:
cargo test --features "online_tests"
cargo test --all-features
然后我按照 ,但它们继续被忽略.
I then added the feature definition into my Cargo.toml
as per this page, but they continue to be ignored.
我在 Cargo 中使用工作区.我尝试在两个 Cargo.toml
文件中添加功能定义,但没有任何区别.
I am using workspaces in Cargo. I tried adding the feature definition in both Cargo.toml
files with no difference.
推荐答案
没有工作区
Cargo.toml
[package]
name = "feature-tests"
version = "0.1.0"
authors = ["An Devloper <[email protected]>"]
[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");
}
输出
$ 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
test filesystem ... FAILED

虚拟清单不支持指定功能(货物问题 #4942).您需要从子项目中运行测试或指定适当 Cargo.toml 的路径
Virtual manifests do not support specifying features (Cargo issue #4942). You will need to run the tests from within the sub project or specify the path to the appropriate Cargo.toml
