Data mining is the procedure of finding useful new correlations, patterns, and trends by sharing through a high amount of data saved in repositories, using pattern recognition technologies including statistical and mathematical techniques. It is the analysis of factual datasets to discover unsuspected relationships and to summarize the records in novel methods that are both logical and helpful to the data owner.It is the procedure of selection, exploration, and modeling of high quantities of information to find regularities or relations that are at first unknown to obtain clear and beneficial results for the owner of the database.It is not limited ...

The data mining system is integrated with a database or data warehouse system so that it can do its tasks in an effective presence. A data mining system operates in an environment that needed it to communicate with other data systems like a database system. There are the possible integration schemes that can integrate these systems which are as follows −No coupling − No coupling defines that a data mining system will not use any function of a database or data warehouse system. It can retrieve data from a specific source (including a file system), process data using some data ... Read More
We can use regular expressions in a CSS locator. We can identify elements by matching their attributes partially with the help of regular expressions. In CSS, there are multiple methods to achieve this. They are listed below −Using the wild character *. This means the string contains our given text.Syntax− driver.find_element_by_css_selector("input[name*='sel']")It will search the input tag which contains the 'name' attribute containing 'sel' text.Using the wild character ^. This means the string starts with our given text.Syntax− driver.find_element_by_css_selector("input[name^='Tut']")It will search the input tag which contains the 'name' attribute starting with 'Tut' text.Using the wild character $. This means the string ... Read More
Data mining defines extracting or mining knowledge from huge amounts of data. Data mining is generally used in places where a huge amount of data is saved and processed. For example, the banking system uses data mining to save huge amounts of data which is processed constantly.In Data mining, hidden patterns of data are considering according to the multiple categories into a piece of useful data. This data is assembled in an area including data warehouses for analyzing it, and data mining algorithms are performed. This data facilitates in creating effective decisions which cut value and increase revenue.There are various ... Read More
We can click on a link using Selenium webdriver in Python. A link is represented by the anchor tag. A link can be identified with the help of the locators like - link text and partial link text.We can use the link text attribute for an element for its identification and utilize the method find_element_by_link_text. With this, the first element with the matching value of the given link text is returned.Syntaxdriver.find_element_by_link_text("value of link text")We can also use the partial link text attribute for an element for its identification and utilize the method find_element_by_partial_link_text. With this, the first element with the ... Read More
We can select an option in a static dropdown in Selenium webdriver. Selenium can handle static dropdowns with the help of the Select class. A dropdown is identified with select tagname and its options are represented with the tagname option. The statement - from selenium.webdriver.support.select import Select should be added to work with Select class.Methods under the Select class are listed below −select_by_visible_text (arg) – it shall select all the options which displayed text matches with the argument.Syntax−sel = Select (driver.find_element_by_id ("name")) sel.select_by_visible_text ('Visible Text')select_by_value (arg) – it shall select all the options having a value that matches with the ...

Selenium supports headless execution. In the Chrome browser, the headless execution can be implemented with the help of the ChromeOptions class. We have to create an object of this class and apply the add_arguments method to it. Finally, pass the parameter --headless to this method.Let us obtain the title - About Careers at Tutorials Point - Tutorialspoint of the page launched in a headless mode −ExampleCode Implementationfrom selenium import webdriver from selenium.webdriver.chrome.options import Options #object of Options class c = Options() #passing headless parameter c.add_argument("--headless") #adding headless parameter to webdriver object driver = webdriver.Chrome(executable_path='../drivers/chromedriver', options=c) # implicit wait time driver.implicitly_wait(5) ...

We can work with the id locator in WebdriverIO. Once we navigate to a webpage, we have to interact with the web elements available on the page like clicking a link/button, entering text within an edit box, and so on to complete our automation test case.For this, our first job is to identify the element. We can use the id attribute for an element for its identification. It is a very useful locator and speeds up the execution of automation tests in comparison to all the locators.In the WebdriverIO code, we have the option to specify the value of the ... Read More
WebdriverIO can perform mouse operations like drag and drop using the dragAndDrop method. With this, we execute clicking and holding events on the present object(source), then pass the object to the target element. Finally, release the mouse.Syntaxlet p = $('#loc') let t = $('#target') p.dragAndDrop(t)Here, p is the source locator and t is the destination locator.Let us perform the drag and drop functionality for the below elements −In the above image, the element with the name - Drag me to my target has to be dragged and dropped on the element - Dropped!.ExampleCode Implementation// test suite name describe('Tutorialspoint application', function(){ ...

We can implement tags in Cypress. Cypress has tags - .only and .skip. While the .only tag is utilized to execute the it block to which it is tagged, the .skip tag is utilized to exclude the it block to which it is tagged.ExampleImplementation with .onlydescribe('Tutorialspoint', function() //it block with tag .only it.only('First Test', function() { cy.log("First Test") }) //it block with tag .only It.only('Second Test', function() { cy.log("Second Test") }) it('Third Test', function() { cy.log("Third Test") }) })Execution ResultsThe output ...
