Selenium supports Functional Testing and Regression Testing.

Selenium grid is the functionality that lets you distribute your tests simultaneously across multiple machines. Selenium Grid helps in reducing the time taken for test execution and provides instant feedback to stack holders.
Selenium Grid could be used to execute the same or different test scripts on multiple platforms and browsers in parallel. It helps achieve distributed test execution, testing under different environments and saving execution timelines.
Setting up a grid with all required browsers and operating systems is a challenge. For this, there are multiple online platforms that provide an online Selenium Grid that you can access to run your selenium automation scripts. For example, you can use LambdaTest. It has more than 2000 browser environments over which you can run your tests and truly automate cross-browser testing.
The Assert command checks is a particular condition is true or false. If the condition is true, the program control will execute the next test step. If the condition is false, the execution would stop and no further tests would be executed.
The Verify command also checks if a particular condition is true or false. Irrespective of the condition being true or false, the program execution doesn’t stop.
Xpath is a locater that is used to locate a web element based on its XML path. XML stands for Extensible Markup Language and is used to store, organize and transport arbitrary data. It stores data in a key-value, similar to HTML tags.
A single slash ( / ) begins selection from the document node, while a double slash ( // ) begins selection matching anywhere in the document.
Verification and Assertion are two Check functionalities. Verification allows test execution to continue even when Check fails, while assertion stops the test execution.

In Selenium, the Implicit Wait function sets a timeout for all successive web element searches.

WebElement el = driver.findElement(By.id(“ElementID”)); el.submit();
String title = (String) js.executeScript(“pass your java scripts”);
String title = driver.getTitle()
String currentURL = driver.getCurrentUrl()
