# Expressions

Panaya test automation enables creating and using a variety of data types and to support adding logic, dynamic [parameter](/v1/docs/parameters) values, and conditional behavior into your automated scripts. These expressions help you calculate values, compare fields, and control flow using operators, [functions](/v1/docs/automation-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’. ![](https://cdn.document360.io/f404076c-de23-4609-848e-2dfd4ef701b0/Images/Documentation/image-ZXIV45BK.png)

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]
> 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’

> 1. Comparison Operators
> 
> To compare a field or variable against a specific value, use standard comparison operators (e.g., `&gt;`, `&lt;`, `=`).
> 
> - **Example:** `{x} &gt; 5`
> - **Example:** `{y} &lt; {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.
