# Swift 测试
|
||
|
||
> 本文档在 [common/testing.md](../common/testing.md) 的基础上扩展了 Swift 特定的内容。
|
||
|
||
## 框架
|
||
|
||
对于新测试,使用 **Swift Testing** (`import Testing`)。使用 `@Test` 和 `#expect`:
|
||
|
||
```swift
|
||
@Test("User creation validates email")
|
||
func userCreationValidatesEmail() throws {
|
||
#expect(throws: ValidationError.invalidEmail) {
|
||
try User(email: "not-an-email")
|
||
}
|
||
}
|
||
```
|
||
|
||
## 测试隔离
|
||
|
||
每个测试都会获得一个全新的实例 —— 在 `init` 中设置,在 `deinit` 中拆卸。测试之间没有共享的可变状态。
|
||
|
||
## 参数化测试
|
||
|
||
```swift
|
||
@Test("Validates formats", arguments: ["json", "xml", "csv"])
|
||
func validatesFormat(format: String) throws {
|
||
let parser = try Parser(format: format)
|
||
#expect(parser.isValid)
|
||
}
|
||
```
|
||
|
||
## 覆盖率
|
||
|
||
```bash
|
||
swift test --enable-code-coverage
|
||
```
|
||
|
||
