Operators

The match operator determines the type of comparison that is made between the message characteristic and the test expression. The match operator determines the nature of the data that should be entered as the test expression.

The available match operators are either strings and lists or numerical expressions, depending on the nature of the message characteristic being tested. For example, if the test analyzes the size of a message component, the operator list contains numerical expressions. If the test analyzes the text of a message, the operator list contains string and list expressions.

Depending on the selected operator, different types of text boxes are displayed for entering test expressions. For example, selecting the Is a member of match operator causes the display of a drop-down list from which you can select a policy test expression list. Selecting Matches regex reveals a text box where a regular expression is entered as the test expression. Selecting Is under reveals a text box where a number can be entered.

Match Operators - Strings and Lists

Match Operators - Numbers

Numerical operators compare the numerical value of the specified message characteristic to the number entered in the expression text box. The numerical operators are greater than (>), greater than or equals to (>=), less than (<), and less than or equals to (<=).

When analyzing the size of message components, the default unit of measure is bytes. To analyze size based on a different unit of measure, append "K" (kilobytes), "M" (megabytes) or "G" (gigabytes) to the number entered in the test expression text box.
