Expressions

Panaya test automation enables creating and using a variety of data types and to support adding logic, dynamic parameter values, and conditional behavior into your automated scripts. These expressions help you calculate values, compare fields, and control flow using operators, functions and parameters.

Whenever your data includes something which is more than just a simple “string”, you can use Expressions to -

• Validate expected results.

• Perform conditional checks.

• Reference field values dynamically.

• Apply simple formulas or transformations.

When using functions, parameters, operators and integers, make sure to check the Expression checkbox. In that case, a string should always be entered inside single quotes e.g. ‘string’.

You can also use the following operators to implement more sophisticated logic to your script:

Basic Operators

You can perform calculations or comparisons.

• Math: +, -, *, /
  Example: {Amount} * 0.15

• Comparisons: =, <>, <, >, <=, >=, !=
  Example -
  {Status} = ‘Approved’

Note

To validate whether a field is empty, compare it to an empty value.

Example -

{Status} = ''

Logical Operators

Combine multiple conditions.

• AND, OR, NOT
  Example -
  {Amount} > 1000 AND {Region} = ‘EU’

Note

1. Comparison Operators

To compare a field or variable against a specific value, use standard comparison operators (e.g., >, <, =).

• Example: {x} > 5

• Example: {y} < {z}

2. Logical Operators

The system supports the primary boolean operators: And, Or, and Not.
Operator:                                     Usage Requirement:                                                                                                            Example:

  And                       Must have a boolean expression on both sides.                                                                    {x} > 5 And {y} < {z}

   Or                       Must have a boolean expression on both sides.                                                                    ({x} = 4) Or ({y} = 8)

  Not                       Must have a boolean expression on the right side.                                                                    Not ({x} > 5)

3. Working with Multiple Values (In Function)

When checking if a single field matches one of several possible values, you can use the In function. This is often more concise than using multiple Or statements.

• Standard Syntax (Or):
  ({x} = 4) Or ({y} = 8)

• Shorthand Syntax (In):
  In({x}, 4, 8)

---

4. Best Practices

• Parentheses: Always use parentheses when using the Not operator or when nesting And/Or conditions to ensure the correct order of evaluation.

• Field References: Ensure all fields are enclosed in curly braces (e.g., {FieldName}).

• Case Sensitivity: Logical operators (And, Or, Not, In) are typically treated as keywords; ensure they are formatted correctly to avoid issues.
