Generating an HTML Data-Digest Verification Function

The WebVerifyDataDigest function calculates a Web page digest and then subsequently verifies content against the precalculated digest. In the case of HTML or XML source code, a digest consists of a character-frequency table, which is calculated for certain characters in a page-response body.

In the menu tree, select the Web page that you want to verify.
Open Source view.
Perform one of the following steps:
- Choose Script > Verify Page Digest .
- Click Add Verifications and then click Verify digest on the Workflow - Add Verifications dialog box.
A name for the digest is displayed in the Constant name text box.
Optional: Edit the Constant name text box.
In the Verify group box, specify how the verification should be applied:
- All characters
- Printable characters
- Alphanumeric characters
In the Severity group box, specify the severity that should be raised if the verification returns a negative result.
Click OK. The function is then added to your test script.

Code Example

The following sample code (in bold) is generated automatically for data digest verifications:

const 
  DATA_DIGEST_1     :=
