Swift Testing默认并行运行测试函数,无论其是同步还是异步,测试函数可根据需要隔离到全局actor。 处理依赖问题:转换旧测试代码时,可能存在隐藏依赖,可先将代码转换为Swift Testing,再解决问题。可使用.serialized trait指示测试套件或参数化测试函数的测试需要串行运行,但应尽量重构测试代码以并行运行。 等待异步条件的技术:...
Swift Testing 还为此提供了一个特定的宏@Suite。属于测试套件的所有测试函数都继承套件的相同 trait,包括tags(_:)或disabled(_:sourceLocation:)。 为了校验测试结果,Swift Testing 提供了两个宏expect(_:_:sourceLocation:)和require(_:_:sourceLocation:)。require会在不满足条件时抛出异常停止测试的执行,而expect...

Learn how to write a sweet set of (test) suites using Swift Testing's baked-in features. Discover how to take the building blocks further and use them to help expand tests to cover more scenarios, organize your tests across different suites, and optimize your tests to run in parallel....
Swift Testing has a clear and expressive API built using macros, so you can declare complex behaviors with a small amount of code. The #expect API uses Swift expressions and operators, and captures the evaluated values so you can quickly understand what went wrong when a test fails. @Test ...
Having trait like functionality is one of the most interesting aspects that Swift has given us. Swift iOS Development Interesting talks in ReactEurope 2016 8 June 2016 I’m always interested in knowing what is going on in other communities, it helps me a lot to understand how others ...
Description: A trait for syntax nodes that have an optional code block, such asFunctionDeclSyntaxandInitializerDeclSyntax. Pull Request:#2359 CodeBlockSyntax Description:CodeBlockSyntaxis nowSyntaxParseable, so it can be used with string interpolations. ...
使用thiserror crate 来定义错误类型,并实现 From trait 以便在函数中使用 Result。 在Cargo.toml 文件中添加 thiserror 依赖: [dependencies] thiserror = "1.0" 在src/lib.rs 中定义错误类型和函数: use thiserror::Error; #[derive(Debug, Error)] pub enum MyError { #[error("Invalid input: {0}")...
Build configuration import testing Swift 4.1 implemented SE-0075, which introduced a new canImport condition that lets us check whether a specific module can be imported when our code is compiled. This is particularly important for cross-platform code: if you had a Swift file that implemented one...
With Swift Testing, time limits are set by adding an extra trait to the @Test macro called .timeLimit(). This lets you specify how many minutes – yes, minutes –the test should be allowed to run for before it's considered a failure....
