 * @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 same parameters as ProcessResult received after
 * completion Process.run method and stderrEncoding was null for completed
 * Process.run method, the [stderr] returns List<int> value.
