Introduction

Automation scripts fail for one main reason.
The application moves faster or slower than the script expects.

This is where synchronization issues appear.

In Quick Test Pro, QuickTest Professional, and HP QTP, synchronization problems cause flaky tests, false failures, and wasted debugging time. A script clicks a button before it loads. A validation runs before data appears. A test fails even when the application works correctly.

Real-world UFT projects face this issue daily.

Modern applications load data dynamically. Pages use AJAX. Objects appear late. Network speed changes. Backend responses vary. If scripts do not wait correctly, automation loses reliability.

This guide explains how to handle synchronization issues in UFT scripts step by step. You will learn concepts, methods, real project examples, and best practices used in enterprise testing teams.

What Is Synchronization in UFT?

Synchronization in UFT means aligning test execution with application behavior.

The script must wait until:

• The object exists
  
  

• The object becomes visible
  
  

• The page finishes loading
  
  

• The data appears
  
  

• The process completes
  
  

If the script moves ahead early, it fails.

In Quick Test Pro, synchronization ensures the script interacts with the application only when it is ready.

Why Synchronization Issues Occur in Real Projects

Synchronization issues happen due to several common reasons:

1. Dynamic Object Loading

Web elements load after page refresh or API response.

2. AJAX and Asynchronous Calls

Data loads without full page refresh.

3. Network and Server Delays

Response time changes based on load.

4. Heavy UI Components

Charts, grids, and reports load slowly.

5. Fixed Delays in Scripts

Hard waits do not match real execution time.

In HP QTP, handling these challenges correctly separates stable automation from fragile scripts.

Impact of Poor Synchronization on Automation

Poor synchronization leads to:

• High test failure rates
  
  

• Increased maintenance cost
  
  

• Reduced trust in automation
  
  

• Delayed releases
  
  

• Manual retesting
  
  

Industry studies show that over 35% of automation failures come from timing and synchronization problems in UI tests.

Strong synchronization strategies improve test stability and execution speed.

Default Synchronization in UFT

UFT has built-in synchronization, but it is limited.

How Default Synchronization Works

UFT waits for:

• Browser readiness
  
  

• Page load completion
  
  

• Object existence (basic level)
  
  

This works only for static pages.

Dynamic applications require explicit synchronization methods.

Common Synchronization Techniques in UFT

Overview of Techniques

UFT provides multiple ways to handle synchronization:

• Wait statements
  
  

• Exist property
  
  

• WaitProperty method
  
  

• Sync method
  
  

• Smart Synchronization
  
  

• Object state validation
  
  

• Custom reusable functions
  
  

Each technique serves a different purpose.

Using Wait Statement in Quick Test Pro

What Is the Wait Statement?

The Wait statement pauses script execution for a fixed time.

Wait 5

This pauses execution for 5 seconds.

When to Use Wait

• Temporary debugging
  
  

• Small delays
  
  

• Non-critical validations
  
  

Why Fixed Wait Is Risky

Fixed waits slow execution and fail if loading time changes.

Best practice: Avoid using Wait as a primary solution.

Using Exist Property for Synchronization

What Is Exist?

The Exist method checks whether an object exists within a given time.

If Browser("App").Page("Home").WebButton("Submit").Exist(10) Then

    Browser("App").Page("Home").WebButton("Submit").Click

End If

Why Exist Works Well

• Waits until object appears
  
  

• Avoids unnecessary delays
  
  

• Improves stability
  
  

In QuickTest Professional, Exist is one of the safest synchronization methods.

Using WaitProperty Method in HP QTP

What Is WaitProperty?

WaitProperty waits until an object reaches a specific state.

Browser("App").Page("Login").WebEdit("Username").WaitProperty "enabled", True, 15

Key Benefits

• Waits for actual condition
  
  

• More reliable than fixed waits
  
  

• Ideal for dynamic UI elements
  
  

This method is widely used in real-time HP QTP projects.

Using Sync Method for Browser Synchronization

What Is Browser.Sync?

The Sync method waits until the browser finishes loading.

Browser("App").Sync

Best Use Cases

• Page navigation
  
  

• Form submission
  
  

• Page refresh
  
  

Note: It does not wait for AJAX calls.

Smart Synchronization in UFT

What Is Smart Synchronization?

Smart Synchronization waits for:

• Browser loading
  
  

• Page ready state
  
  

It is enabled by default.

Why It Is Not Enough

Modern apps load content after page ready state. Smart Sync alone cannot handle dynamic data.

Always combine Smart Sync with explicit waits.

Handling AJAX Synchronization in UFT

Problem with AJAX

AJAX loads data without refreshing the page.

Solution: Wait for Object State

Browser("App").Page("Dashboard").WebTable("Results").WaitProperty "rows", 5, 20

This waits until data loads.

Synchronizing Using Object Properties

Property-Based Validation

Check properties like:

• visible
  
  

• enabled
  
  

• text
  
  

• innertext
  
  

Example:

Browser("App").Page("Home").WebButton("Save").WaitProperty "visible", True, 15

This ensures UI readiness.

Creating Reusable Synchronization Functions

Reusable functions reduce duplication and errors.

Example Function

Function WaitForObject(obj, timeOut)

    If obj.Exist(timeOut) Then

        WaitForObject = True

    Else

        WaitForObject = False

    End If

End Function

This improves maintainability in large Quick Test Pro frameworks.

Real-World Project Example

Scenario

A banking dashboard loads account details after login using AJAX.

Problem

Script validates balance before data loads.

Solution

Browser("Bank").Page("Dashboard").WebElement("Balance").WaitProperty "innertext", "", 20

Result

• Reduced failures
  
  

• Stable execution
  
  

• Faster debugging

Synchronization in Keyword-Driven Frameworks

In keyword frameworks, synchronization logic sits in utility functions.

Benefits:

• Central control
  
  

• Easy updates
  
  

• Consistent behavior
  
  

Every HP QTP framework should include synchronization utilities.

Synchronization in Data-Driven Testing

Data-driven tests run multiple iterations.

Without synchronization:

• First iteration passes
  
  

• Next iteration fails
  
  

Solution:

• Reset application state
  
  

• Apply waits between iterations

Debugging Synchronization Issues

Common Debugging Steps

1. Use step-by-step execution
   
   

2. Highlight objects
   
   

3. Print timestamps
   
   

4. Log execution time
   
   

5. Validate object states
   
   

Debugging helps identify where the application lags.

Best Practices for Handling Synchronization

Follow These Rules

• Avoid fixed waits
  
  

• Use WaitProperty over Wait
  
  

• Validate object states
  
  

• Build reusable sync functions
  
  

• Handle AJAX explicitly
  
  

• Keep sync logic separate
  
  

• Monitor execution logs
  
  

These practices improve automation success rates.
