Use the Verification Point Comparator to compare verification point data after you play
back a script with a verification point and to update the baseline file. If the verification point
failed, the Comparator shows both the expected and actual values, so you can analyze the
differences. You can then load the baseline file and update it with the values from the actual
file.
To open the Comparator, click the View Results link in the IBM® DevOps Test UI (Test UI) HTML log. For information, see the
related topic about viewing results in the log. The Comparator banner displays the name of your
verification point.
- Play back the script that contains the verification point
on a new build of the application under test.
The
log for the playback is displayed. For information about setting the
option that makes the log open automatically after playback, see Logging
Preferences Page.
- Open the log for the verification point.
- If you are using the HTML log, click the View Results link.
(Note that if you experience an error regarding the Java™ plug-in
when trying to start the Comparator from the View Results link
in the HTML log, verify that your plug-in is configured properly.
- Open the Comparator from the log.
- If one verification point failed, select the log in the Projects view, right-click the log, and click Failed Verification
Points.
- If you have more than one failed verification points the Results
for Verification Points wizard opens. Click a failed verification
point in the list and click View Results or
Finish.
The Verification Point Comparator opens to
display that verification point. The Comparator includes the expected
and actual data values. The expected values were tested. The actual
values were captured in the application during playback. If the verification
point failed, the differences are shown in red.
For the data verification
point types list, table and text, the expected values are displayed
on the left and the actual values are displayed on the right. The
differences are shown in red. For the data (menu hierarchy) and data
(tree hierarchy) verification points, the expected and actual values
are shown contiguously. The expected values of the differences are
shown in red, and the actual values of the differences are shown underneath
them in green.
- Look at the two data files to compare any differences between
the expected and actual files. By analyzing differences in the Comparator,
you can determine if they are intentional changes to the application
or defects.
To navigate through the differences, use the
navigation buttons on the toolbar above the data display.
- If you want to edit the baseline file to update the information
for future playbacks, you must load the baseline file. Click File
> Baseline or click the Load Baseline to Edit toolbar
button
.
The baseline file replaces the expected file on the left side
of the display.
- To edit individual items in the data, edit them in the
baseline (left) column of the display. When you finish editing the
data, click Save.
For a Data
(Text) verification point, click Edit Text 
to start a text editor to make your edits. For
other verification point types, you can edit directly in the baseline
data display.
- For a Properties verification point, if you determine that
the baseline value and actual value for a specific property are different,
you can update the baseline value. In the Verification Point Comparator,
right-click the property where the values are different, and click
Replace Baseline on Current Selection.
- If you determine that all the differences reflect intentional
changes to the application under test, and you want to update the
baseline to reflect the changes, you can use the Replace
Baseline with Actual Value toolbar button
to replace the entire baseline
file. - If you have made any individual changes to the baseline
data file (not by using the Replace Baseline with Actual
Value command), click File> Save to
save the changes.
- When you finish comparing and updating verification point
data, click to exit the Verification Point Comparator.
