如何定义仅测试依赖项? [英] How to define test-only dependencies?

问题描述

我有一个实现 lint 插件的 Rust 库.我想包含 compiletest，但在测试之外不需要它.指定依赖项仅用于测试的正确方法是什么?

I have a Rust library that implements a lint plugin. I want to include compiletest, but not require it outside of testing. What is the correct way to specify that the dependency is for testing only?

推荐答案

是的.使用 dev-dependencies.来自 货物文档:

Yes. Use dev-dependencies. From the Cargo docs:

您可以将 [dev-dependencies] 部分添加到您的 Cargo.toml 中，其格式等同于 [dependencies]:

You can add a [dev-dependencies] section to your Cargo.toml whose format is equivalent to [dependencies]:

[dev-dependencies]
tempdir = "0.3"

在编译用于构建的包时不使用开发依赖项，但用于编译测试、示例和基准.

Dev-dependencies are not used when compiling a package for building, but are used for compiling tests, examples, and benchmarks.

如果可能，您还应该使用 Cargo 的 resolver version 2 更好地处理复杂的开发依赖情况.

When possible, you should also use Cargo's resolver version 2 to better handle complicated dev-dependency cases.
