      • write

        public void write​(int i)
        Specified by:
        write in class java.io.OutputStream

      • write

        public final void write​(byte[] b,
                        int off,

        write in class java.io.OutputStream

      • capturedString

        public java.lang.String capturedString()
        Returns:
        the string that was written to System.out or System.err

      • capturedLines

        public java.lang.String[] capturedLines()
        The capturedString(), divided on the line separator.

        This includes leading, inner, and trailing empty lines but does not include the potential empty string that comes after a trailing line separator. (The exact algorithm is based on but behaves differently from String.split(String).)

        Because the return value does not include a trailing empty line that comes from a trailing line separator, it can't be used to distinguish the cases where the last line was created by a print or a println. For more details and examples on this, see the documentation on standard input/output.

        Returns:
        the lines that were written to System.out or System.err
