In the modern design experience, UiPath offers a range of UI synchronization activities. These activities include:

Check App State Activity

This activity allows you to check the state of an application, ensuring that it is in the expected state before proceeding with further actions.

The Check App State activity in UiPath verifies the state of an application or web browser by monitoring the appearance or disappearance of a specific element. It allows for executing different sets of activities based on whether the element is found or not.

This activity extends beyond checking a single UI element and can observe the entire application for changes.

We can also use this as a condition within the Retry Scope activity, enabling retries based on the application's state.

Additionally, the Check App State activity can be used independently of the Use Application/Browser activity. This provides the flexibility to monitor and control the application or web browser state throughout your automation process.

By leveraging the Check App State activity, you can create dynamic and robust automation workflows that adapt to the evolving states of applications and browsers, and enhancing the reliability and effectiveness

Verify Execution Feature

With this feature, you can verify that a specific action or activity has been successfully executed before moving on to the next step.

The Verify Execution feature in UiPath is used to validate the correctness of actions performed by activities at runtime. It verifies the desired outcomes by checking and confirming the appearance or disappearance of specified elements after the activity is executed.

The Verify Execution feature is a property available for the Click, Type Into, and Hover activities.

By leveraging the Verify Execution feature, you can enhance the accuracy and reliability of automation processes. It helps validate and verify the expected changes and states in UI elements, making sure the correct execution of actions.

The key features of this feature are:

Expected Text Verification: with Verify Execution, you can specify the expected text to be verified for the Type Into activity. This makes sure that the correct text is entered into the defined field.

Retry Mechanism: the Verify Execution feature provides a retry mechanism that allows for automatic retries of the activities if the expected outcome isn't initially achieved. This increases the chances of a successful execution.

Element State Verification: the feature enables the verification of element states such as appearance, disappearance, changes in text, or changes in image. This makes sure the desired states are achieved after the activity execution.

Pick Branch Activity

The Pick Branch activity provides a flexible way to synchronize and execute different branches of activities based on specific conditions or events.

Please note that in the classic design, there were several synchronization activities, but in the modern design, they have been consolidated into the Check App State activity for improved efficiency and simplicity.

The Pick activity is like having someone who can keep an eye on multiple things at once and knows what to do when something happens. It tracks different events or conditions happening simultaneously and determines the appropriate action based on the first event that occurs.

The Pick Branch activity is like a group of tasks connected to a specific thing being watched. When that thing happens or changes, the tasks in that group are executed. These activities help in efficiently managing and responding to different situations, making sure the right actions are taken at the right time.

The Pick activity is a container activity in workflow automation that allows you to monitor multiple input sources simultaneously and execute the appropriate branch of activities based on the first available input.
The main component of the Pick activity is the Pick Branch activity.
Pick Branch represents a specific branch or path of activities within the Pick activity.
Each Pick Branch contains a set of activities that'll be executed when the associated trigger becomes true or the event occurs.
The main components of the Pick Branch activity are Triggers and Actions.
Triggers are conditions or events that determine when the branch should be executed. They can be created using variables, expressions, or invoking other workflows.
Actions are the activities or tasks that are performed when the trigger condition is met.
Multiple branches can be defined within the Pick activity, allowing you to handle different conditions or events simultaneously.
Each branch can have its own trigger condition and a set of actions to be executed.

Asynchronous Activities

Asynchronous activities in UiPath Studio enable parallel execution and non-blocking operations, enhancing the performance and flexibility of automation workflows. These activities allow tasks to run independently, reducing waiting times and increasing efficiency.

Here are some use cases where asynchronous activities can be beneficial in automation workflows:

Data Retrieval and Processing

When fetching data from multiple sources or APIs, asynchronous activities can be used to make concurrent requests, speeding up the data retrieval and processing tasks.

File Operations

When performing operations like copying, moving, or deleting files in bulk, using asynchronous activities can help improve the overall speed and efficiency of the file handling process.

Web Scraping

Asynchronous activities can be employed for scraping data from multiple web pages simultaneously, reducing the overall execution time of the scraping task.

Database Operations

When executing database operations such as querying, updating, or inserting data into multiple tables or databases, asynchronous activities can be used to parallelize the tasks and improve overall database performance.

API Integrations

Asynchronous activities are valuable in scenarios where multiple API calls need to be made concurrently, enabling efficient integration with external systems and reducing response time.

Long-Running Tasks

For tasks that require substantial processing time, such as large-scale data transformations or complex calculations, asynchronous activities can be utilized to perform the operations in the background while allowing the workflow to continue with other tasks.

Distributed Processing

In scenarios where automation processes need to be executed across multiple machines or robots, asynchronous activities enable parallel execution, maximizing resource utilization and reducing the overall execution time.

 

Parallel Activities

The Parallel Activity in workflow design allows for the simultaneous execution of multiple independent tasks within a workflow. It acts as a container for activities, facilitating coordinated and concurrent execution.

In UiPath Studio, the Parallel activity can be found in the Activities panel, under Workflow > Control > Parallel.

The Parallel activity finishes only after all child activities are complete or when its Completion Condition property evaluates to true.

Why is it important?

The parallel allows these tasks to be done at the same time, without waiting for each other.

Where do I use it?

It's ideal for scenarios involving parallel processing, multitasking, or handling multiple events or conditions simultaneously.

For Example:

You have a requirement to monitor multiple folders in a system, and you want to implement a solution that can handle the monitoring of these folders concurrently. By using Parallel Activity, you can streamline the process and achieve efficient monitoring.

The Parallel Activity allows developers to create workflows that can execute multiple activities concurrently. This enables efficient parallel processing and can greatly enhance the performance of complex workflows.
Drag and drop activities onto parallel branches. These branches represent separate threads of execution that can run simultaneously.  
Each parallel branch operates independently of the others, enabling the execution of activities concurrently without dependencies. This is especially beneficial when dealing with tasks that can be performed in parallel and do not rely on the outcomes of activities from other branches. 
The Parallel Activity also provides synchronization mechanisms to coordinate the execution of activities across parallel branches.
