Ans: Protractor is a wrapper around Selenium Webdriver that offers Automation; take a look at the framework, which simulates user interaction with an Angular web application for a number of browsers and mobile devices.
It presents all functions of Selenium WebDriver alongside Angular-particular functions for seamless end-to-give-up testing.
Ans: Here are the simple factors of variations among Selenium and Protractor:
|Supported Front End Technology-Based Web Application||Supports all the front stop generation||Specially designed for Angular and AngularJS packages|
|Browser support||Chrome, Firefox, Internet Explorer ( IE), Microsoft Edge, Opera, Safari, HtmlUnitDriver||Chrome, Firefox, Internet Explorer ( IE), Microsoft Edge, Safari|
|Synchronization or Waiting||Synchronization or Waiting Does now no longer assist automated synchronization among exams and applications. Instead, it desires to be explicitly synchronized with the use of one-of-a-kind waits.||Supports Automatic look forward to Angular packages; however, they're no longer relevant for Non-angular packages. But you may explicitly synchronize waits in Protractor.|
|Supported Locators Strategies||Supports not unusual place locator techniques like Id, className, name, linkText, tagName, partial hyperlink text, XPath, and CSS for all internet packages||Supports not unusual place locator techniques like Id, className, name, linkText, tagName, partial hyperlink text, XPath, and CSS for all internet packages plus it additionally helps angular precise locator techniques consisting of version, repeater, binding, buttonText, option, etc. additionally allows the introduction of custom locators.|
|Supported test frames||
Based on language binding, it helps diverse Test Frameworks C#- NUnit,
Java- JUnit, TestNG
|The rapporteur helps Jasmine and Moka. The Protractor is supplied with Jasmine as a default framework.|
|Support for BDD||Yes. (Serenity, Cucumber, JBehave, etc.).||Yes. Mocha, Jasmine, Cucumber, and Serenity/JS|
|Managing browser drivers||Requires third-celebration equipment like Webdriver Manager to sync browser model and driving force.||Requires internet driving force-supervisor CLI to automated sync among browser models and driving force for Chrome and Firefox.|
|Parallel Testing||Parallel testing Requires third-party equipment such as TestNG.||Supports parallel testing.|
|Ease to automate Angular Applications||Not easy; a number of sync problems, and hard to discover actual wait conditions.||It is made for angular packages; for this reason, it is simple to automate Angular Applications|
|Test Execution Speed||Slower||Faster|
ElementFinder: The ElementFinder practically shows a single Element Array Finder (and similar to a single object). To build up a chain of locators, we can use ElementFinder.
ElementArrayFinder: For an array elements, you can use ElementArrayFinder(alternately a single detail). For example, the ElementArrayFinder helps to install the sequential terms belonging to an array of elements.
Jasmine: This represents a substructure, for example, Junit (Java) and Unit Test (Python). This is a mix of various functions, and it's a far better default framework while executing in Protractor.
Ans: You can use the following commands to install Protractor on windows:
Use npm to install Protractor globally with:
npm install -g Protractor
Ans: You can easily set up a project in Protractor, so your machine must have node.Js runtime mounted. The npm helps node.Js which you can use easily.
npm i -g protractor or
npm deploy -g Protractor
This command installs each Protractor and Web cause force-Manager. Once Protractor is established, you can test the version using
Once Protractor runs, we can use Chrome Driver or the Gecko Driver for running the browser.
After completion, you can start the software setup for your project. The related process needs to note down- create a file using the spec.Js document and for config use the conf.Js file.
Ans: You can use this syntax to select a checkbox-
element(by. model('attribute.name')). click();

Ans: Few locators available in Protractor are as follows:
Ans: To get a text on an input in the Protractor, you can use:
Ans: You can use cucumber by updating the framework with the path.
Ans: You can select an option from the dropdown in Protractor e2e testing with the following step:
Ans: You can use the following code to set the default window size in
Protractor/WebdriverJs: browser.executeScript('window.moveTo(0,0);' + 'window.resizeTo(screen.width, screen.height);');
Ans: The current URL will come in Protractor by using this syntax:
browser.getCurrentUrl() as follows: expect(browser.getCurrentUrl()).toEqual("expectedUrl");
Ans: We can use the syntax; sendKeys() command
Ans: With the help of the following syntax, you can create a promise in Protractor:
var deferred = protractor.promise.defer();
var promise = deferred.promise;
Ans: MaxInstances in Protractor is the number of browser instances that can run in parallel for the set of capabilities.
Ans: We need two files to run:
Configuration file: The configuration file is the only one that tells Protractor where to discover the check files (specs)/which browser to pick/which framework to use (Jasmine/Mocha)/where to speak for your Selenium browser and other configurations. If any configuration isn't described in configuration files, it'll use defaults.
Spec file: Spec file is the only where we write our real code. All of our purposeful flow/assertions might be on this particular report. There are probably numerous spec files primarily based totally on the wide variety of taking a look at instances; however, simply one spec report might be capable of running the complete take a look at the suite of numerous specs.
Ans: If you set direct connect: true in your config file, your test script will communicate directly with Chrome Driver or Firefox Driver. The use of directly connecting to browser drivers is that your test scripts may begin to run faster.
Ans: Mouse actions that can be performed using Protractor are:
Ans: You can verify tooltip text using Protractor; we need to fetch the value of the 'title' attribute.
Ans: The timeout test is the time allotted for performing unit testing. The protractor discontinues further testing if the unit test fails to meet the specified time limit and marks it as a failure.
Ans: To extract the CSS attribute of an element in Protractor, grtCSSValue can be used.

Ans: To have your web driver script switch between different frames, you can use the following code:
Ans: Get method loads a page or gets the page source or gets a text.
On the other hand, navigate method allows functions like refresh, back, and forward.
Ans: It is possible to set global variables using parameters present in the config file that can be accessed in the specs using:
Ans: GeckoDriver location finds the geckodriver.exe file. This gets passed to the Selenium jar as the system property.webdriver.gecko.driver.
Ans: XPath is one of those locators that are supported by Protractor and is a query language for selecting nodes from XML documents.
A headless browser mode means running web applications without a graphical user interface. Instead, the applications will get executed through commands via a command-line interface. In headless browser mode, the Protractor executes the tests in the background.
Ans: When we search for an element with the XPath index, we might get more than one element that is under different parents. The group index places all the resulting element matches into a list and gives indexes for them. The group index numbers start with 1.
Ans: Yes, we can implement drag and drop in Protractor using actions(). Here is the code for it. Syntax:
Ans: In Protractor, while running tests, this is a common problem when the Protractor execution starts, but the Angular code is still trying to synchronize the $http or $timeout requests. So set the browser. Ignoring synchronization actually means that we're telling Protractor not to wait for the Angular promises to be resolved.

Ans: Since Protractor tests are asynchronous and it relies on a lot of components, there are various reasons for which timeouts can occur in Protractor tests.
This may include:
Ans: The best reporter is Chercher-tech-jasmine-reporter is a more suitable report for the Protractor and Jasmine jointly.
Ans: Textarea doesn't have much difference from the text bar, so we can handle it like a normal text box/text bar element.
Ans: There are different attributes in web components like 'title.' If we bring the data from this attribute, By fetching the value of the 'title' attribute, then need to check the tooltip text in Protractor.
Ans: The Protractor can be used easily with the default framework, named Jasmine 2.0. However, anyone can also use frameworks like mocha, Cucumber JS, Serenity, etc.
Ans: Absolutely Yes. It can be used with TypeScript.
Ans: You can use the upload Locator to insert the custom locator in Protractor.
Ans: The perquisites are JDK, Web Driver (selenium standalone jar record), and browser.
Ans: Apart from the standard locator mechanism that is Selenium, Protractor also has a few Angular JS locators.
Ans: Definitely, you can go with Protractor. Protractors may be used for finding out non-Angularjs or non-Angular apps.
Ans: In general, most of the e2e implementation is in default Jasmine 2.0. You can use this e2e implementation to insert something in Protractor.
Ans: The Protractor does not come with any signaling device as a reporter. So, for example, you can use Allure with Jasmine 2.0 with Protractor and Mocha with Cucumber, particularly for reporting.
Ans: By default, any spec in Protractor will fail after 30 seconds. Yes, this timeout duration can be configured to be superior or changed.
Ans: In order to run more than one spec document in Protractor, you need to do it in the spec flag in an array. E.g., say you've given particular spec files test1_spec.Js and test2_spec.Js so that you can do that like this-
Specs: ['. /test/test1_spec.Js','./test/test2_spec.Js']
This will make Protractor run more than one spec file.
Protractor is an open-source testing framework that provides the following benefits:
For testers to keep up with the increased demands for faster delivery and maximum software quality, test automation is essential.
