[英]Run additional tests by using a feature flag to “cargo test”
I have some tests that I would like to ignore when using cargo test
and only run when explicitly passed a feature flag. 我有一些在使用cargo test
时要忽略的cargo test
,只有在明确通过功能标志时才运行。 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. 我知道这可以通过使用#[ignore]
和cargo test -- --ignored
ignored来完成,但是出于其他原因,我想拥有多组被忽略的测试。
I have tried this: 我已经试过了:
#[test]
#[cfg_attr(not(feature = "online_tests"), ignore)]
fn get_github_sample() {}
This is ignored when I run cargo test
as desired, but I can't get it to run. 当我根据需要运行cargo test
时,将忽略此操作,但是我无法使其运行。
I have tried multiple ways of running Cargo but the tests continue to be ignored: 我尝试了多种运行Cargo的方法,但测试仍然被忽略:
cargo test --features "online_tests"
cargo test --all-features
I then added the feature definition into my Cargo.toml
as per this page , but they continue to be ignored. 然后,按照该页面的说明 ,将功能定义添加到我的Cargo.toml
中,但它们仍然被忽略。
I am using workspaces in Cargo. 我在Cargo中使用工作区。 I tried adding the feature definition in both Cargo.toml
files with no difference. 我尝试在两个Cargo.toml
文件中添加功能定义,没有区别。

Virtual manifests do not support specifying features (Cargo issue #4942) . 虚拟清单 不支持指定功能(货运问题#4942) 。 You will need to run the tests from within the sub project or specify the path to the appropriate Cargo.toml 您将需要在子项目中运行测试,或指定适当的Cargo.toml的路径。
