After Verify is completed, the tree in the Extractor Verification tab will show extractors' values.  There is a status image showing whether an exception in handling the extractor was encountered next to every extractor. One of 4 statuses can be assigned to an extractor:

a. The extractor is OK.

b. The extractor is not found in the response.

c. The recorded and replayed token extractors are the same.

d. The recorded and replayed extractors are the same.

The status (e) is displayed when mouse-over the extractor.


The autocorrelation process creates extractors and parameters to avoid test execution errors. However, some of these parameters may be unnecessary. If the test machine is overloaded, you can reduce performance overhead by deleting unnecessary parameters.  The extractors with statuses b, c, and d are automatically selected for easy removal. To remove them, click Delete (f) on the toolbar.

To search the Extractor Verification tree, use search control (g).

The value returned by a  selected extractor is displayed in the property grid (h).

If the value is a long string, notice the replayed and recorded value length (i). If the lengths are really different, then the extracted value may not be accurate.

If recorded and replayed token extractors are the same, it may indicate an incomplete token correlation.


Troubleshooting script by comparing  extractor's sessions

Comparing recorded sessions where an extractor was created with the same session on playback can be helpful for script troubleshooting. For example, if the extractor was not found on playback, then such comparison can expose the root cause of the issue that may be a consequence of an issue in the previous session.

To use this troubleshooting methodology, right-click on the extractor node and select Compare Extractor's Sessions. After that, a new tab will display Compare Sessions Inspector for the extractor's session.
