# Swift Testing
|
||
|
|
|
||
|
|
> This file extends [common/testing.md](../common/testing.md) with Swift specific content.
|
||
|
|
|
||
|
|
## Framework
|
||
|
|
|
||
|
|
Use **Swift Testing** (`import Testing`) for new tests. Use `@Test` and `#expect`:
|
||
|
|
|
||
|
|
```swift
|
||
|
|
@Test("User creation validates email")
|
||
|
|
func userCreationValidatesEmail() throws {
|
||
|
|
#expect(throws: ValidationError.invalidEmail) {
|
||
|
|
try User(email: "not-an-email")
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## Test Isolation
|
||
|
|
|
||
|
|
Each test gets a fresh instance — set up in `init`, tear down in `deinit`. No shared mutable state between tests.
|
||
|
|
|
||
|
|
## Parameterized Tests
|
||
|
|
|
||
|
|
```swift
|
||
|
|
@Test("Validates formats", arguments: ["json", "xml", "csv"])
|
||
|
|
func validatesFormat(format: String) throws {
|
||
|
|
let parser = try Parser(format: format)
|
||
|
|
#expect(parser.isValid)
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## Coverage
|
||
|
|
|
||
|
|
```bash
|
||
|
|
swift test --enable-code-coverage
|
||
|
|
```
|
||
|
|
|
||
|
|
