Summary0005603: MaxStringLength test problem (Base Info Server Capabilities/006.js)
Description

In Step 1, CTT attempts to write a string of length MaxStringLength and expects the string to be accepted.
In Step 2, CTT is supposed to attempt to write a string of length MaxStringLength + 1, and expects the server to report the "OperationResults: BadOutOfRange" error. However, in reality, the length of the string CTT attempts to write in this test is different from MaxStringLength + 1 (typically shorter, thus the server accepts such string).

Steps To Reproduce
  1. The OPC UA Server under test has MaxStringLength = 1000.
  2. CTT attempts to write a string of length 1000, the Server accepts it.
  3. CTT attempts to write a string of length 5 (althought it is supposed to attempt to write a string of lenght 1001), and the Server accepts it too.
  4. CTT complains that the Server did not report the OperationResults: BadOutOfRange error

The read Value of the ServerCapabilities.MaxStringLength variable is not interpreted as a number and therefore the generation of the longer string in WriteService.GenerateString( 1 + stringLen ) does a ( 1 + stringLen.length) and therefore generates a string which has the number of characters of the length (e.g. 4 when having the limit set to 4096) + 1 which results in a string length of 5 in the generated string.
Now the limit is interpreted as a Number and the generation of the string works.
