Creating Expressions in the Expression Builder
The Expression Builder is a software component of TestComposer that is used for creating conditional expressions contained in looping and flow control steps such as For, While, Do...While, and For. The Expression Builder can also be used for creating and editing simple or multi-line Tcl code fragments and Tcl expressions as part of Composer test steps.
The Expression Builder GUI used for defining the conditional expression has two working modes that you can use interchangeably, a Basic mode—which uses a natural-like expression format based on mathematical operators and Composer variables—and an Advanced mode, which permits the creation of more complex conditional expressions that include variables and Tcl commands, operators and even Tcl code portions.
The Expression Builder working mode Basic or Advanced that is selected by default when creating or editing conditional expressions is determined by the Default expression editor for conditional steps option configured in the Appearance page of the Options window (Tools | Options...).
