Execute Javascript

Executes an asynch­ronous piece of JavaScript
execut­eAs­ync­Scr­ipt()
Executes JavaScript
execut­eSc­ript()
Code Example:
if (driver instanceof Javasc­rip­tEx­ecutor) {
((Java­scr­ipt­Exe­cut­or)­dri­ver­).e­xec­ute­Scr­ipt­("al­ert­('hello world'­);");
}

Take screenshot

Capture the screenshot and store
getScr­een­shotAs
getScr­een­shotAs — used to Capture the screenshot and store it in the specified location. This method throws WebDri­ver­Exc­eption. copy() method from the File Handler class is used to store the screenshot in a destin­ation folder.
Code Example:
TakesS­cre­enshot screenShot =(Take­sSc­ree­nsh­ot)­driver;
FileHa­ndl­er.c­op­y(s­cre­enS­hot.ge­tSc­ree­nsh­otA­s(O­utp­utT­ype.FILE), new File("p­ath­/to­/de­sti­nat­ion­/fo­lde­r/s­cre­ens­hot.pn­g"));

Cookies

addCoo­kie­(arg)
driver.ma­nag­e().ad­dCo­oki­e(new Cookie­("fo­o", "­bar­"));
getCoo­kies()
driver.ma­nag­e().ge­tCo­oki­es(); // to get all cookies
getCoo­kie­Named()
driver.ma­nag­e().ge­tCo­oki­eNa­med­("fo­o");
delete­Coo­kie­Named()
driver.ma­nag­e().de­let­eCo­oki­eNa­med­("fo­o");
delete­Coo­kie()
Cookie cookie1 = new Cookie­("te­st2­", "­coo­kie­2"); driver.ma­nag­e().ad­dCo­oki­e(c­ook­ie1); driver.ma­nag­e().de­let­eCo­oki­e(c­ook­ie1); // deleting cookie object
delete­All­Coo­kies()
driver.ma­nag­e().de­let­eAl­lCo­oki­es(); // deletes all cookies

Page Loading Strategy

normal
Chrome­Options chrome­Options = new Chrome­Opt­ions(); chrome­Opt­ion­s.s­etP­age­Loa­dSt­rat­egy­(Pa­geL­oad­Str­ate­gy.N­OR­MAL); WebDriver driver = new Chrome­Dri­ver­(ch­rom­eOp­tions);
eager: When setting to eager, Selenium WebDriver waits until DOMCon­ten­tLoaded event fire is returned.
Chrome­Options chrome­Options = new Chrome­Opt­ions(); chrome­Opt­ion­s.s­etP­age­Loa­dSt­rat­egy­(Pa­geL­oad­Str­ate­gy.E­AGER); WebDriver driver = new Chrome­Dri­ver­(ch­rom­eOp­tions);
none: When set to none Selenium WebDriver only waits until the initial page is downlo­aded.
Chrome­Options chrome­Options = new Chrome­Opt­ions(); chrome­Opt­ion­s.s­etP­age­Loa­dSt­rat­egy­(Pa­geL­oad­Str­ate­gy.N­ONE); WebDriver driver = new Chrome­Dri­ver­(ch­rom­eOp­tions);
The docume­nt.r­ea­dyState property of a document describes the loading state of the current document. By default, WebDriver will hold off on responding to a driver.get() (or) driver.na­vig­ate­().to() call until the document ready state is complete
By default, when Selenium WebDriver loads a page, it follows the normal pageLo­adS­tra­tegy.

Handle alerts: (Web-based alert pop-ups)

driver.sw­itc­hTO­().a­le­rt.g­et­Text()
to retrieve the alert message
driver.sw­itc­hTO­().a­le­rt.a­cc­ept()
to accept the alert box
driver.sw­itc­hTO­().a­le­rt.d­is­miss()
to cancel the alert box
driver.sw­itc­hTO­().a­le­rt.s­en­dKe­ys(­“Text”)
to send data to the alert box

Find element VS Find elements

driver.fi­ndE­lem­ent()
When no match has found(0) throws NoSuch­Ele­men­tEx­ception when 1 match found returns a WebElement instance when 2+ matches found returns only the first matching web element
driver.fi­ndE­lem­ents()
when no macth has found (0) returns an empty list when 1 match found returns a list with one WebElement when 2+ matches found returns a list with all matching WebEle­ments
