Expression Builder allows you to build numeric and text based expressions. You can access this from the Statement menu in action logic editor.
Expressions are helpful in building concatenated strings or for performing numeric calculations for verification in test logic.
String expressions allow any arbitrary string or parameters to be combined together.
Numeric expressions allow mathematical calculations involving either hard coded numbers or parameters. You can also specify the decimal precision to be used in the result of the calculation. Following operations are supported:
Plus (+), minus (-), multiplication (*), division (/), parenthesis (())
Parameters are indicated with angle brackets around the name of the parameter.
The value of an expression is always assigned to a local or action output parameter. Once you save and close the parameter, you specify the assignment parameter, just like you do in regular statement creation process.
Note: In case you need to insert a "<" or ">" character as a literal in the expression, prefix with "\".
