Explores how constants, variables, and operations are combined to form expressions that can be included in your tests. Through careful use of variables and expressions, your tests can be flexible, modular, powerful, and compact.

What you will learn:

How variables are used to store different types of data
How expressions are formed from numeric and string operations
How variables, by acting as placeholders for actual values, lend reusability to expressions and actions
How data can be converted from one type to another
How wildcards can be used to add flexibility to searches and comparisons

Prerequisites:

Audience: Testers, Automation engineers

Duration: 2 hours

Understanding variables and expressions
Action arguments can contain variables (symbols that hold actual values) or expressions, involving operations on variables and constants.
Using string expressions
Use the concatenation operation to manipulate text in action arguments.
Working with string variables
You can use variables to store text strings, which can be used in place of string constants in your cell expressions.
Performing numeric operations
Write numeric operations, such as addition and division, in your action arguments. Such operations can operate on both numeric constants and variables.
Mixing types
Text and numeric data types can be combined in cell expressions.
Working with mixed types
Combine numeric and string operations in single expressions, operating on both numeric and text values.
Using variables in mixed expressions
Use numeric and string variables, as well as constants, in your mixed expressions.
Wildcards
In strings that are used as expected values, and in searches, the wildcard substring is used to represent any character or group of characters.
Using wildcards
Use a wildcard to allow a check action to match a range of dates.
