throwsFileSystemException function

Matcher throwsFileSystemException([
  1. dynamic osErrorCode
])

Returns a matcher that successfully matches against a future or function that throws a FileSystemException.

If osErrorCode is specified, matches will be limited to exceptions whose osError.errorCode also match the specified matcher.

osErrorCode may be an int, a predicate function, or a Matcher. If it is an int, it will be wrapped in an equality matcher.

Implementation

Matcher throwsFileSystemException([dynamic osErrorCode]) =>
    throwsA(isFileSystemException(osErrorCode));
