Test automation is all about get and set, which means get from web and set into web.
Talking more specifically-
What I meant from get is, reading a webobject property e.g. Reading a label value of web, which is using findelement.
What I meant by set is, setting values in web for e.g. Inserting values in a text box, clicking a button, selecting a radio button, again using findelement method.
So findelement is a method which helps in interaction with a web page.
How it’s represented and does it work-
It’s written as –
Driver. Findelement(By. Id("")). Click().
WebDriver object allows access to findelement and with help of web object property is finds the designated object and perform operation.
There is another method which is known as findelements.
What is findelements()?
If a web object returns multiple values then findelements are used.
There should be some list, set or array variable be mentioned on the left side which can contain/store returned values-
It’s represented as-
List <WebElement> list= driver. Findelements(By. Id() ) ;
If you can compare with findelement method there is no click or get text method called. Same is done while in list object by iterating it Inside a loop.
el. Gettext() ;
