verification & parsing
9 In the Severity portion of the dialog box, specify the severity that is to be
raised if the verification returns a negative result (Error, Warning,
Informational, or Custom).
10 Click OK.
11 A confirmation dialog appears. Click OK to add the OCR verification
function to your Citrix test script.
Procedure To generate an OCR parsing function:
1 From SilkPerformer record a Citix session as described in the “Creating
a Load Test Script” section of this chapter.
2 Run a TryScript run, with the Animation checkbox selected on the
TryScript dialog. This opens TrueLog Explorer.
3 When the TryScript run is complete, select the API node that includes the
bitmap screengrab of the screen on which you’d like to parse text.
4 Click and drag your cursor onscreen to select the screen region that
includes the text you would like to parse.
5 Right-click in the selected area and select Parse Text from the context
menu.
6 The Insert Parsing Function dialog offers parameters by which the
parsing function can be configured. Though the default settings will
likely be correct, you can adjust:
- Parameter name - Enter the name of the parameter that is to receive
the result of the parsing function.
- Informational statement insertion - Select Print statement to insert
an informational Print statement into the script after the Web page
call. This writes the result of the parsing function to SilkPerformer's
Virtual User Output window.
Select Writeln statement (“write line” statement) to write the parsed
value to an output file to facilitate debugging (in addition to writing
the value to the Virtual User Output window as a Print statement
does). Because generating output files alters load-test time
measurements, these files should only be used for debugging
purposes and should not be generated for full load tests.
7 Click OK.
8 A confirmation dialog appears. Click OK to add the OCR parsing
function to your Citrix test script.
String verification via optical character recognition (OCR) is achieved using
CitrixVerifyText API calls. These functions are inserted via TrueLog Explorer
