Top 50 C# Interview Questions And Answers For Experience & Freshers 2022 Update

It creates a connectivity between Java Programming Language and the database. Some of the best continuous testing softwares to use in your project. Some of the continuous integration tools are Jenkins, TeamCity, Bamboo, Travis, Circle Ci, Bitbucket. In simple words, continuous integration is a process of verifying the correctness of a software.

Here, each resource is identified by URIs or global IDs, and REST uses multiple ways to represent a resource, such as text, JSON, and XML. XML and JSON are nowadays the most popular representations of QA Automation Engineer C# job resources. API enables communication between two separate software systems. A software system implementing an API contains functions or subroutines that can be executed by another software system.

As a multi-paradigm programming language, C# also has some features of functional programming that takes its usefulness and versatility to a step further. Keep implicit wait at starting and explicit wait on a specific condition. You could create explicit wait as a function and call whenever you want that explicit wait. Hi Neeraj, explain all the components of your framework as I mentioned in this post.

As per the official Selenium documentation, it is suggested not to mix both Implicit waits and Explicit Waits. Mixing both of them can cause unpredictable wait times. Stale Element means an old element or no longer available element. Assume there is an element that is found on a web page referenced as a WebElement in WebDriver.

By automating the process, you can eliminate human error and ensure that your tests are always carried out the same way. This can be particularly important when testing complex applications where there is a greater risk of errors. Well, the whole concept of Captcha is to ensure that bots and automated programs don’t access sensitive information – which is why, Selenium cannot automate it. The automation test engineer has to manually type the captcha while other fields can be filled automatically. The grid was designed to distribute commands to different machines simultaneously. It allows the parallel execution of tests on different browsers and different operating systems.

What Are Major Challenges Faced In Api Testing?

RESTful web services use the HTTP protocol as a communication tool between the client and the server. The technique that when the client sends a message in the form of an HTTP Request, the server sends back the HTTP reply is called Messaging. These messages comprise message data and metadata, that is, information on the message itself.

Finally, let’s move to the element and execute the action. Understanding locators and thesendKeys()methods in Selenium play an essential role in automating test cases that interact with forms. Since this is one of the most common use cases, it is foundational knowledge for any QA Engineer. Once you’ve located the element, you can use thesendKeysfunction to send a string to the input box.

The following set of questions test a candidate’s hands-on experience with writing Selenium tests. Candidates should be able to answer 6 of the 10 questions below at a minimum. Test automation scripts are often asynchronous, so understanding the different types of waits and when to use them are essential.

  • Provide an example of a time when you identified and reported a flaw in a product or service.
  • TestNG listeners are used to configure reports and logging.
  • Both sleep() and setSpeed() are used to delay the execution speed.
  • The page class is responsible for finding the WebElements in web pages and then perform operations on WebElements.
  • These messages comprise message data and metadata, that is, information on the message itself.

The web driver implementation HTML Unit Driver is the fastest of all. This is because this driver does not execute the tests in the browser but rather, executes only the plain HTTP which is quick faster as expected. Encoding and Serialization in the AJAX applications make it difficult in developing the automation test case scenarios. A driver instance should be created for a particular browser which we need to work upon.

What Is The Procedure To Perform Api Testing?

As a value type, an unitialized DateTime variable is set to a default value of midnight of 1/1/1 (yup, that’s the year 1 A.D.), not null. Salient features of QTP include Business Process Testing, keyword driven framework, XML support, robust checkpoints, test results. Preparing Grant Chart of Project timelines for test script development & execution.

In this framework, the functionality of the test scenarios is documented in the table step by step. It also uses the given locating mechanism to find all the elements within the current page and return the list of all web elements. It’s only to specify whether the given condition is true or false. The test fails and gets terminated whenever there is a fail in the check. This path starts from any node in between and to the desired elements node. This path starts from the root node and ends with the desired elements node.

The tests then use the methods of this page object class whenever they need to interact with the User Interface of that page. Object Repository is used to store element locator values in a centralized location instead of hard coding them within the scripts. We do create a property file (.properties) to store all the element locators and these property files act as an object repository in Selenium WebDriver. Sometimes web controls don’t react well against selenium commands and we may face issues with the above statement (click()). To overcome such kind of situation, we use JavaScriptExecutor interface.

What Are The Differences Between Soap And Rest?

Even though there is no default one still we could create our own. One of the ways to create Object Repository is to place all the locators in a separate file (i.e., properties file). In the Page Object Model Design Pattern, each web page is represented as a class.

These fields are listed in CSV files, excel files, text files, XML files, etc. These files are then fed to the automation tool for execution, which compares the expected and actual data. Then the obtained results are documented in the result field. Selenium webdriver is an object oriented tool which consists of various classes and namespaces with which we can perform various actions on the web elements or controls.

Interview Questions For Test Automation Engineers:

Whenever you run a program in C#, the main thread runs automatically. Here, we created an instance of the Rectangle class and then called the two different methods. Now a single delegate will invoke these two methods Area and Perimeter.

Apauseon an exception is a feature in the Selenium IDE debugger to pause test script execution when a runtime error is thrown. This allows the developer to inspect the page to better debug the exception in real time. To type text into an inbox box using Selenium WebDriver, you’ll first need to locate the element usingfindElement(). You can locate the input using a locator,,By.path(),By.CSSSelector().

Lists of top 10 used automation testing tools for Functional Automation are as follows. A list of most frequently asked Selenium interview questions, and their answers are given below. When using WebDriver, you can launch applications by either calling the “get” method on the driver instance, or by using the “navigate” method.

Functional testing – Functional Testing involves the verification of every function of the application with the required specification. Regression testing – It is a full or partial selection of already executed test cases that are re-executed to ensure existing functionalities work fine. In C#, the type-safety feature prevents one type of object from interfering or peeking into the memory of another type of object. Initializing a Parameter Value in Calling Method – It is a compulsion to initialize a parameter value within the calling method while using out. However, the same is optional while using the ref parameter. The memory allocated for the value type content or assigned value is stored on the stack.
