# XCTSkipUnless(_:_:file:line:)

Skips remaining tests in a test method unless the specified condition is met.

## Declaration

```swift
func XCTSkipUnless(_ expression: @autoclosure () throws -> Bool, _ message: @autoclosure () -> String? = nil, file: StaticString = #filePath, line: UInt = #line) throws
```

## Parameters

- `expression`: A Boolean expression.
- `message`: An optional description of the skip.
- `file`: The file where the skip occurs. The default is the filename of the test case where you call this function.
- `line`: The line number where the skip occurs. The default is the line number where you call this function.

## Discussion

Call this method to skip any remaining code and assertions in the test method when `expression` evaluates to `false`, and mark the test method as skipped. If a test failure occurs in the test method before the skip, the test runner marks the test method as failed.
