/**
 * @assertion dynamic stderr
 *
 * Standard error from the process. The value used for the stderrEncoding
 * argument to Process.run determines the type. If null was used this value is
 * of type List<int> otherwise it is of type String.
 *
 * @description Checks that if constructor [ProcessResult] creates a new object
 * of type ProcessResult with the same parameters as ProcessResult received
 * after completion Process.run method and stdoutEncoding was not set to null
 * for completed Process.run method, the [stderr] returns String value.
