Selenium

traverse from first sibling to, second sibling

("first sibling's locator/following-sibling::div")

when we have two items with same locator, how tell selenium to choose the second one?

(locator)[2]

to store the result in a list in stream:

.collect(Collectors.toList())

to take a screenshot

1. convert your driver object to screenshot object 2. use method: getScreenshotAs() File src= ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);

how to sum up the values in a table exp.

1. create an integer variable and initialize with 0. 2. make a for loop to iterate through all items you want to sum up

how to make a hub:

1. download selenium server jar 2. invoke it in command prompt and assign the hub role to it: C:\>java -jar file's name.java -role hub 3. cmd gives you an IP address with port number: "Nodes should register to http://10.1.1.21:4444/grid/register/" 4.copy this address and paste it to browser and add /console at its end: http://10.1.1.21:4444/grid/console

connect a node to HUB

1. using Remote desktop, connect(login) to remote device that you want to register as node 2. download selenium server.jar file in the node machine, as well. 3. open the command prompt of the node machine and write the command to register to the hub: 4. location:\>java -jar file's name.jar -role webdriver -hub http://10.1.1.21:4444/grid/register -port 5566 5. to execute test cases, Download chromedriver or geckodriver on node machine and place in the path where exactly selenium server file is located 6. add this part to cmd: Java -Dwebdriver.chrome.driver="C:\chromedriver.exe" -jar selenium ...

we have a list of strings, create an object of it's arraylist

ArrayList<String> names=new ArrayList<String>();

convert an array to arraylist

Arrays.asList(array) - example: List<String>names=Arrays.asList("hk","hm","jyfu","ghg");

how to compare two lists?

Assert.assertTrue(firstList.equal(secondList))

class used to chrome browser

ChromeOptions

class to customize the Chrome browser

DesiredCapabilities

tell chrome browser certificates (2)

DesiredCapabilities ch=DesiredCapabilities.chrome(); ch.setCapability(CapabilityType.ACCEPT_INSECURE_CERTS, true); ch.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true); ChromeOptions c=new ChromeOptions(); c.merge(ch); System.setProperty("webdriver.chrme.driver", "C:\\chromedriver.exe"); WebDriver driver=new ChromeDriver(c);

take screenshot

File src= ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE); FileUtils.copyFile(src,new File("C:\\Users\\Mary\\screenshot.png"));

method to store the source object to our local machine

FileUtils().copyFile(source,target)

convert string to integer

Integer.parsInt(string variable name)

Assert.assertTrue(condition, message) :-

It takes one boolean argument and String message. It Asserts that a condition is true. If it isn't, an AssertionError, with the given message, is thrown.

Assert.assertFalse(condition) :-

It takes one boolean arguments and checks that a condition is false, If it isn't, an AssertionError is thrown.

how to see dynamic elements in page(usage of javascript )

JavascriptExecutor js = (JavascriptExecutor)driver; String script = "return document.getElementById(\"autocomplete\").value;"; String text = (String) js.executeScript(script); System.out.println(text);

how to enter javascript to your code?

JavascriptExecutor js=(JavascriptExecutor)driver; String mum="return document.getElementById(\"fromCity\").value;"; String text=(String) js.executeScript(mum); System.out.println(text);

make the equal expression fo this" ArrayList<String> names2=new ArrayList<String>(); names2.add("Abhijeet"); names2.add("Don"); names2.add("Alekhya"); names2.add("Adam"); names2.add("Rama");

List<String> names2=Arrays.asList("Abhijeet","Don","Alekheya","Adam","Rama");

when you want to click many links and open in separate tabs

List<WebElement> links=firstColumn.findElements(By.tagName("a")); String clicker=Keys.chord(Keys.CONTROL,Keys.ENTER); for (int a=1;a<links.size();a++){ links.get(a).sendKeys(clicker); }

open each of several links in a new tab

List<webElements> tabs=driver.findElements(By.tagName("a")); String clickByTab=Key.chord(Keys.CONTROL,Keys.ENTER); for (int i=1,i<tabs.size(),i++) { tabs.get(i).sendKeys(clickByTab);

to give the HUB role to a machine:

Location:\>java -jar file's name -role hub

what is a dropdown class in selenium?

Select

select "H" from dropdown list (static dropdown)

Select s=new Select(driver.findElement(By.id("dropdown's id"))); s.selectByValue("H"); if in html the item has value="H"

switch selenium to child tabs

Set<String> abc=driver.getWindowHandles(); Iterator<String> it=abc.iterator(); String parentWindow=it.next(); String childWindow=it.next(); driver.switchTo().window(parentWindow); driver.switchTo().window(childWindow);

sending selenium to different tabs

Set<String> abc=driver.getWindowHandles(); Iterator<String> itt=abc.iterator(); while (itt.hasNext()) { driver.switchTo().window(itt.next()); System.out.println(driver.getTitle());

directly create a stream

Stream.of("hcb","whch","hjegdh","hbc")

when we have two " in a line

String jscode="document.getElementById(\"fromCity\"); add \ before each "

how to grab an element's value?

how to switch back to the parent window after closing the child window

SwitchTo(). Window(driver. WindowHandles[0])

see an element's value

what .jar is needed to support Assert

TestNG

choose a desired text from a dropdown

WebElement dropdown=driver.findElement(By.id("dropdown-class-example")); Select s=new Select(dropdown); s.selectByVisibleText("text");

how to place a package in java project

go to eclipse and right click on your project/ properties/ java build path/ click on Add external jars button/ choose the files you unzipped

assertion will stop your script if

it reaches: fail

.map()

let us modify stream filter results

names is an arraylist write a code to display only the items that are more than 4 characters

names.Stream().filter(s->s.length>4).forEach(s->System.out.println(s));

names is an arraylist write a code to display only the first item that is more than 4 characters

names.Stream().filter(s->s.length>4).limit(1).forEach(s->System.out.println(s));

how to identify the second item with same locator, instead of writing index?

parent child addressing: parentLocator childLocator

move one step forward in eclipse debugging mode

press F6

choose opt from a dropdown

s.selectByVisibleText(opt);

what is stream

stream is a collection of strings

names2.stream().filter(s->s.startsWith("A")).limit(1).forEach(s->System.out.println(s)); what does "limit(1)" do here?

the sentence will only return one answer (the first one)

to retrieve a value

use "return": String script="return document.getElementById(\"fromCity\").value;";

when to use filter() method in streams?

when we want to apply conditions

go down through a list option until you reach: BENGAlURU INTERNATIONAL AIRPORT

while(!text.equalsIgnoreCase("BENGALURU INTERNATIONAL AIRPORT")) { driver.findElement(By.id("fromPlaceName")).sendKeys(Keys.DOWN); }
