# Validate
The Validate command is used to confirm the presence, visibility or correctness of UI elements, screen states, text or application responses. Drizz identifies the target using visible labels, contextual hints or screen-level structure. Manual inspection steps or screenshot matching are not required, as Drizz intelligently verifies the specified UI state using Vision AI.
## 1. Basic Validate
### 1.1 Validating directly visible text or elements
Used when the target is clearly identifiable on the screen.
**Examples:**
Validate Home is visible
Validate Order Placed tag is visible
Validate Login CTA is visible
Drizz confirms the presence of the exact label on the visible screen.
## 2. Validate With Contextual Field or Section Reference
When multiple identical labels exist, providing context ensures precise targeting.
### 2.1 Using section-level context
Validate Active tag is visible in subscription section
Validate Apply CTA is enabled in the coupon area
### 2.2 Using header or parent section
Validate Address is present under Profile
Validate Total in the order summary section
### 2.3 Using nearby or associated element
Validate In Stock tag near product title
Validate ₹499 next to MRP is present
## 3. Validating Multiple Similar Texts or Repeated Elements
Used when the same text appears multiple times on screen. In case of presence of multiple UI with similar tags, use more context for better execution of command.
Example:
Validate Apply CTA is present beside the first coupon
Validate cancel CTA is disabled beside Apply coupon of first coupon
### 3.1 Distinguishing by position
Validate the first "Add" CTA
Validate the last "Remove" CTA
### 3.2 Distinguishing by element grouping
Validate "Edit" is present inside personal details section
Validate "Select" is enabled in delivery options
### 3.3 Tables, lists, and repeated list-items
Validate "Delivered" tag is visible in order history list
Validate "Pending" is visible in task row
## 4. Advanced Calculation Validation Using Drizz MCP
Drizz includes an in-house Mathematical MCP that performs advanced arithmetic and multi-field validations directly from the UI. No formulas or scripting are required, simply describe the calculation to validate.
Examples:
1. Validating Summations:
1. Validate that total equals sum of item prices
2. Validate that cart value equals sum of all product costs
2. Validating Discounts & Percentage Logic
1. Validate that discount equals 10% of subtotal
2. Validate that final price reflects applied coupon discount
3. Validating Price Details & Final Amount
1. Validate that final amount equals subtotal + tax + delivery charges
2. Validate that payable amount equals total - discount
4. Validating Savings & Differences
1. Validate that savings equal MRP minus selling price
2. Validate that cashback equals 5% of total amount
5. Validating List or Table-Based Totals
1. Validate that invoice total equals sum of all row items
2. Validate that line item amount equals unit price multiplied by quantity
6. Multiple Calculations in One Command (Single Line)
1. Validate the following calculations: 1. Subtotal+Tax=Total 2. Total-Discount=Final Amount
## 5. Validate Dynamic, Changing or Auto-Updated UI States
Used when validating screens that update content dynamically (checkout totals, search results, recommendations).
#### 5.1 Text expected after dynamic data load
Drizz waits until the UI is loaded and attempts three validation attempts.
#### 5.2 Auto-updated total or computed values
Validate "₹999" in summary section
Validate discount displayed is correct
### 6. URL-based validation
Validate URL contains "/checkout"
Validate URL is ""
### 7. Edge Cases
#### 7.1 Validation attempted during loading or transition
Drizz waits until the UI is loaded and attempts three validation attempts.
#### 7.2 Validating dynamic labels with partial matches
Validate text contains "Success"
Validate text starts with "Order"
