We can stop the page loading in Firefox programmatically. This can be done by first setting page load time with the help of the pageLoadTimeout method.The time to wait for the page load is passed as a parameter to that method.Syntaxdriver.manage().timeouts().pageLoadTimeout(10, TimeUnit.MILLISECONDS);The page is forced to stop from loading with the help of the Javascript Executor. Selenium executes JavaScript command (window.stop() to stop page load) with the help of the executeScript method.Syntax((JavascriptExecutor)driver).executeScript("window.stop();");Exampleimport org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.firefox.FirefoxDriver; public class StopPageLdWait{ public static void main(String[] args) { System.setProperty("webdriver.gecko.driver", "C:\Users\ghs6kor\Desktop\Java\geckodriver.exe"); ...

Selenium RC is a key part in Selenium. It is a framework for testing that allows testers and developers to design test scripts in multiple languages to automate frontend UI test cases. It has a client library and a server that starts and quits the browser sessions by defaultServer injects Selenium core (a program in JavaScript) to the browser. The Selenium Core gets the commands from the RC server. Selenium Core executes the commands in JavaScript. Then the JavaScript commands provide instructions to the browser. Finally, the browser runs the instructions given by the Selenium Core and sends a complete ... Read More
Indexing is used to speed up query execution in PostgreSQL, and any relational database in general. PostgreSQL tables primarily support several index types. Let us discuss 3 frequently user index types in brief −HashThese indexes can only handle equality comparisons. In other words, if I want to check if itemA = itemB, then hash indexes are useful. It is not suited for other types of operations, like >, =, 40then this index will be useless, and PostgreSQL will organize the query plan assuming the index doesn’t exist.B-treeThis is the default index used by PostgreSQL. In other words, if you ... Read More

Simplify things, shift everything to one table!”So you decide to add the perc_marks column to the student_info table.ALTER TABLE student_info ADD COLUMN perc_marks integerNow, how will you populate this column? Will you manually add the marks for each column? That will leave the room open for a lot of errors and will also be very time-consuming. Instead, this is what you could do −UPDATE student_info ...

We can handle the situation in which the Firefox is not responding with the help of the Selenium webdriver in Python. This can be achieved with the help of the FirefoxProfile class.We shall create an object of this class and apply the set_preference method on it. Then pass these preferences − dom.max_script_run_time and dom.max_chrome_script_run_time with their values set to 0 as parameters to that method.Finally, this information shall be sent to the webdriver object.Syntaxf = webdriver.FirefoxProfile() f.set_preference("dom.max_chrome_script_run_time", 0) f.set_preference("dom.max_script_run_time", 0)We can get the above parameters of the browser by following the below steps −Open the Firefox browser.Type about:config in browser ...

The ability to define JSON columns in PostgreSQL makes it very powerful and helps PostgreSQL users experience the best of both worlds: SQL and NoSQL.Creating JSON columns is quite straightforward. You just have to create/ define it like any other column and use the data type as JSON.Let us create a new table in PostgreSQL, called json_test −CREATE TABLE json_test( serial_no SERIAL PRIMARY KEY, name VARCHAR, metadata JSON );Now, let us populate it with some data −INSERT INTO json_test(name, metadata) VALUES ('Yash', '{"marks_scored":{"science":50, "maths":65}}'), ('Isha', '{"marks_scored":{"science":70, "maths":45}}');As you can see, the JSON values are added within single ...
