UiPath Interview Questions and Answers

Ans:

Uipath is a process Automation vendor through that tool we can automate any type of process.

8.What is the difference between Test Automation & Process Automation?

Ans:

Test Automation –For testing purpose we automate the application & getting the result that how many test cases is pass & fail

Process Automation –Automating the process without human intervention is called Process automation.

9.How many types of variables & direction of argument you have used till now?

Ans:

Mostly used variable are:-

• String, Int32, Double, Data Table, Array, List ,Generic Value ,Boolean
• For more variables you can click browse for types in the variable panel.

Direction of Argument:-

• In ,Out, In/Out

10.Difference between Array, List & Enumeration?

Ans:

1. 1. Array : The array variable is a type of variable which enables you to store multiple values of the same type. UiPath Studio supports as many types of arrays as it does types of variables. This means that you can create an array of numbers, one of strings, one of Boolean values and so on.
2. 2. List : If you want to work with a collection that doesn’t have fixed number of elements ,you can use a list instead of any array.
3. 3. Enumeration : It is fixed data type.

11.What is the value & type of scope used in UiPath?

Ans:

Value –It is an input method where we provide the input.

12.What is the difference between Sequences, Flowchart & State Machine?

Ans:

• Sequence:-The sequence is actually the small type of projects which are suitable mainly for linear processes & will enable you to switch from one activity to another seamlessly. It actually acts as a single activity block. We can reuse them many times.
• Flowchart –It helps in large jobs as well as in small projects & you can also use them in different projects Flowcharts help in presenting multiple branching of logical operators, helps in building complex business & for connecting the activities in many ways. Flow Switch & flow decisions are the same things but it has one difference & that is in the flow switch each branch of flow switch is known as flow step & it is not just restricted to true or false.
• State machine-when a machine is using a certain number of states for automation during the execution it is known as the state machine. it will only switch from one state to another if any action is triggered.

13.What are properties in UiPath?

Ans:

There are multiple activities that can be used to automate apps or web-apps and you can find them in the Activities panel, under the UI Automation category.

All of these activities have multiple properties in common:

• ContinueOnError – If the ContinueOnError field of an activity inside a Try Catch is set to True, no error is caught when the project is executed.
• DelayAfter – adds a pause after the activity, in milliseconds.
• DelayBefore – adds a pause before the activity, in milliseconds.
• TimeoutMS – specifies the amount of time (in milliseconds) to wait for a specified element to be found before an error is thrown. The default value is 30000 milliseconds (30 seconds).
• WaitForReady – Before performing the actions, wait for the target to become ready.

14.What is branching in Uipath?

Ans:

For connecting the activities we are using the branch in Flowchart.

15.What is Selector & types of selector?

Ans:

To automate specific actions in the user interface, you are required to interact with various windows, buttons, drop-down lists and many others. Most RPA products do this by relying on the screen position of UI elements, a method that is not at all dependable. To overcome this problem, UiPath Studio uses what we call selectors.

Wildcards are symbols that enable you to replace zero or multiple characters in a string.

16.Types of Wildcards in UiPath?

Ans:

• Asterisk (*) – replaces zero or more characters
• Question mark (?) – replaces a single character

17.Difference between Full & partial Selector.

Ans:

Full selectors:

• Contain all the elements needed to identify a UI element, including the top-level window
• Generated by the Basic recorder
• Recommended when switching between multiple windows

Partial selectors:

• Generated by the Desktop recorder
• Do not contain information about the top-level window
• Activities containing partial selectors are enclosed in a container (Attach Browser or Attach Window) that contains a full selector of the top-level window
• Recommended when performing multiple actions in the same window
• Example of a partial selector for the editable panel in Notepad

18.What is Uipath Explorer?

Ans:

UI Explorer is an advanced tool that enables you to create a custom selector for a specific UI element. It is available only if the UiPath.UIAutomation.Activities package is installed as a dependency to the project.

To open the UI Explorer window, click the button in the Selectors section, in the Design tab.

19.What is Automatic Recording in UiPath?

Ans:

Automatic recording is very useful and time-saving as it can provide you with a skeleton for your business processes, and can be easily customized and parameterized.

20.Types of recordings available in Uipath?

Ans:

• Basic:- generates a full selector for each activity and no container, the resulting automation is slower than one that uses containers and is suitable for single activities.
• Desktop:  suitable for all types of desktop apps and multiple actions; it is faster than the Basic recorder, and generates a container (with the selector of the top-level window) in which activities are enclosed, and partial selectors for each activity.
• Web:-designed for recording in web apps and browsers (supported: Internet Explorer, Google Chrome), generates containers and uses the Simulate Type/Click input method by default.
• Citrix :-  used to record virtualized environments (VNC, virtual machines, Citrix, etc.) or SAP, permits only image, text and keyboard automation, and requires explicit positioning.

21.What is a managed package in UiPath?

Ans:

The package manager functionality enables you to download activity packages, libraries, frameworks, wrappers and others, view the ones already installed on your computer and update them, as well as add and remove your own.

These features are available through the Manage Packages window that you can open by clicking the Manage Packages button on the Activities panel.

22.How to publish any project in UiPath?

Ans:

• Publishing an automation project means archiving the workflow and all the other files in the folder so that it can be sent to Robots and then executed.
• Additionally, automation projects may be published to a custom NuGet feed, with the option to also add an API key if the feed requires authentication.
• Publishing projects locally requires you to provide a path on the local machine, different from the location where process packages are published. From here, you can later manually send the packages to the Robots, so they can be executed. The default local publish location is %ProgramData%\\UiPath\\Packages

23.How to run bot through robots?

Ans:

If development is completed, we will deploy bot to the orchestrator, So that’s why we will publish that & connect orchestrator through robot, we will provide all the data in the uipath robot setting.

24.How to run bot through command prompt & create shortcut of robot?

Ans:

First we have to publish that from the design panel, then we have to take that publish nuget package location & -file your .xaml location.

25.How to save credentials in windows & use through Uipath?

Ans:

First we have to install system credential from Uipath manage package then we will save all credentials in credential manager. We will take secure credential activity & will fetch that user id & password in two variables & pass into web application or whatever process we want to automate.

26.How to automate databases?

Ans:

For database automation you have to install Uipath.database activity from Manage package,

& You have to provide all the details of whatever database you are using in activity properties.

27.How to create a database connection with Uipath & take the data from the database?

Thick client: It is an application that we get a pretty handful of attribute features using RPA tool e.g. calculator, Internet Explorer.

32.Have you automated a virtual machine?

Ans:

A virtual machine(VM) is an emulation of a computer System. Virtual machines are based on computer Architecture & provide functionality of a physical computer. Examples such as citrix,RDP, Microsoft Azure etc.

As the click activity is not reliable it is not very reliable in virtualized environments.

33.What is debugging in Uipath?

Ans:

Debugging is the process of identifying and removing errors from a given project. Coupled with logging, it becomes a powerful functionality that offers  information about your project and step-by-step highlighting, so that you can be sure that it is error-free. Logging enables you to display details about what is happening in your project in the Output panel. This, in turn, makes it easier for you to debug an automation. Breakpoints enable you to pause the execution of a project so that you can check its state at a given point.

34.Difference between Step into & Step over in Uipath?

Ans:

Step into we use step by step running the program & step over for fast execution.

35.What are arguments in Uipath & directions of Argument?

Ans:

Argumenteds are used to pass data from a workflow to another Workflow. They have specific directions In/Out/InOut.Arguments are used to pass data from a project to another. Additionally, arguments have specific directions (In, Out, In/Out, Property)

IN – Which means they are passed in and not returned.

OUT – A parameter marked OUT usually means that the value of the parameter when it is being passed to the function is not of any importance.

In fact, if it is being passed by pointer, it may even be required to be NULL, and the function will allocate memory and pass a value back to you. Assign activity is required for this type of argument otherwise this argument will not take any value.

An IN/OUT parameter usually indicates something where both the input and output values are meaningful.

36.What is Switch & flow switch In Uipath?

Ans:

The Switch activity enables you to select one choice out of multiple, based on the value of a specified expression.

A FlowSwitch activity works like a FlowDecision except instead of being restricted to a True and False branch. Each branch of a FlowSwitch activity is called a FlowStep. 

37.What is the difference between for each, for each row & parallel For each?

Ans:

• For Each– allow you to iterate through a collection of items. It can be an array, a list, a datatable etc.
• For each row-When using For each you need to specify the data type and because you might need to iterate through a datatable more often you have the specific Activities for Data tables.
• Parallel for Each-Asynchronous executes a series of activities on each element of an enumeration, in parallel. 

38.What is Exception Handling?

Ans:

Exception Handling mainly deals with handling errors with respect to various activities in UiPath. The Error Handling activity offers four options: Rethrow, Terminate Workflow, Throw, Try Catch. 

39.What is the difference between Throw, Rethrow & terminate workflow?

Ans:

Rethrow is used when you want activities to occur before the exception is thrown.

Terminate workflow is used to terminate the workflow the moment the task encounters an error.

Throw activity is used when you want to throw an error before the execution of the step.

40.What Is Value And Scope Of Data Types In Uipath?

Ans:

Variable is used for storing data. You can also change the value of the variable. When some data is stored within some variable then that value can be of many types. In uipath, there is a huge number of data types starting from text number, generic value, time, date and data tables. 

41.What Are Arguments In Uipath?

Ans:

Argument helps the program to create some arguments where you can also make some changes. In arguments, you have to mention the name which is mandatory. Write about the direction and select the argument type whether they are a string, object, Int 32 or array.

42.What Are Selectors And Wildcards In Uipath?

Ans:

Wildcrafts help in replacing the strings. It is helpful when you will deal with the attributes which are changing dynamically in the selector. And the selector helps in automatically generating the selection by using the wildcraft.

43.Why Do You Perform Data Scraping In Uipath?

Ans:

Data scraping helps in enabling the extraction of structured data, document or application. Structured data is a group of information that is organized and presented in a predictable pattern.

44.What Is The Assign Activity In Uipath?

Ans:

We need the assign activity because it helps in assigning values to the variables. Mostly they are used when there is a need for incrementing the variable’s value when there is a loop. You can add the value and then store them to another variable or it helps in assigning the value to some array. 

45.What Is The Delay Activity In Uipath?

Ans:

Uipath uses the delay activity for making you pause or stop the automation for some period. This is mainly used in projects where you need good timing like waiting and then starting some particular applications or waiting for information processing which you can use in the different activity.

46.What Is The Do While Activity In Uipath?

Ans:

Do while helps in enabling the programme to execute the specific part of an automation when the condition will be true. If the condition is not true then the loop won’t be executed. This activity is used to step through the element present in the array or it also helps in executing any particular activity for many times. You can use counters for keeping track of the increment. 

47.What Is The Activity In Uipath?

Ans:

If activity is used when you will deal with two conditions where the first statement will get executed if the condition is true while the second one will get executed when the statement will be false. When the variable will have values then the if statement is basically used. 

48.What Is a Package Manager In Uipath?

Ans:

With the help of the package manager, you can easily download the activity packages, frameworks, libraries, wrappers etc and you can also check the ones which are already present in the container and you can also update them or add or remove them. All these features are only possible because of the manage packages window which you can easily open by clicking the package manager button by pressing on the activity panel.

49.What Is Project Debugging In Uipath?

Ans:

Debugging is used for identifying as well as showing the error for a particular project. It has breakpoints and logging and it is a type of powerful functionality which will help you to gather information about the project and will highlight the errors step by step. Logging helps you to know what your projects are going through when the programming is done and is shown in the output panel. Which helps in making the process of debugging easier. Whereas breakpoints help in pausing the execution of your project to helps you check the state of the program at a particular point. 

50.How Can You Enable Image And Text-based Process Automation?

Ans:

If you want to enable the image and text-based process automation, you will have to see that the uipath has some features that will simulate the keyboard or mouse input, like hovering, clicking, text recognition, OCR activities etc that helps for identifying UI elements by screen scraping. Image or text automation is basically used in the situations where the UI automation won’t work like in the environment of the virtual machine or in the places where finding selectors by using the normal methods is not easy.

53.Is Robotic Automation Like Screen Scraping Or Macros?

Ans:

No, managerial Robotic Automation is a generation ahead from old technologies like screen scratching or macros.

Differences:

Robots are universal application orchestrators – any application that can be used by a man can be used by a present day robot, whether mainframe, bespoke application, legacy, web service enabled or even a close 3rd party API hosted service.
Robots assemble procedural knowledge, which after some time, joins a shared library that can be re-used by some other robot or device.
Applications are “read” by the robot, either through submitted APIs where they exist, through the OS before application appears, or through the screen with respect to the native application. In this last case, the modern robot “reads” an application screen in context and in the same way a user does. As part of the robot training it is shown how to read the application’s display much like a user.
