Graphical Text Diff Utility

A graphical XML diff engine and visualizer are available to compare XML files and graphically display their differences.

Start the Graphical Text Diff Utility

Follow these steps:

  1. Select Actions, Graphical Text Diff from the main menu.

    The Graphical Text Diff window opens. From this panel, you can compare the contents of two XML files.

  2. Click Compare Icon right arrow to start the compare.

    The following window opens, which shows the actual comparison. The Diff Viewer tab shows the comparison.

    Graphical Text Diff - Diff Viewer tab

 

To start the Graphical Text Diff utility from the Interactive Test Run (ITR) utility:

  1. Select the Test Events tab in the ITR.
  2. Right-click a table row and select Select Left Text to Compare.
  3. Right-click a table row to compare with and select Compare To.

    The Graphical Text Diff utility opens for comparison.

 

While in the Graphical Text Diff utility, you can also load the contents by selecting a file.

Follow these steps:

  1. Click the Select Contents tab in the Graphical Text Diff window.
  2. To load the file, click Load from File.

    The results of the diff are then displayed in the global tray panel component.

Note: You can also set the compare options in the Settings tab. For more information about the compare options, see Graphical XML Side-by-Side Comparison in Using CA Application Test.

Graphical Text Diff Utility Properties

The Graphical XML diff utility uses the following properties. These properties can be overridden in local.properties or at run time.

lisa.graphical.xml.diff.engine.max.differences

This property configures the maximum number of differences that are detected before the XML diff algorithm stops. Set to -1 to compute all differences. When there are many differences, this setting causes the XML diff algorithm to finish faster.

Default: 100

lisa.graphical.xml.diff.report.max.linewidth

This property configures the maximum width of a line of text in the XML diff results report. If the input XML has long lines of text, this property causes the XML diff results report to consume less memory.

Default: 80

lisa.graphical.xml.diff.report.max.numberoflines

This property configures the maximum number of context lines for a difference in the XML diff results report. If the XML that is being compared has different elements that are large, this property causes the XML diff results report to consume less memory.

Default: 5

Note: In most cases, these values should not be changed. Changing the default values for these properties could result in the Graphical XML diff engine using more CPU or running out of memory, or both.
