Selenium : How to Create Xpath


Selenium : How to Create Xpath

https://www.w3.org/TR/xpath/#path-abbrev
Target URL: www.mouthshut.com
Target Web element: Signup button, Login Button
Tools used:
·         FireBug : To formulate Xpath
·         Selenium Ide : To Test the formulated Xpath
Things to remember:-
1.       Target page should be open is FireFox
2.       Selenium ide and Firebug  should be open
3.       The formulated Xpath will go into “Target” field of Selenium IDE.
4.       All Xpath which go into IDE start with “xpath=//”
5.       The page usually start with <body> , therefore the foremost parent will always be “//Body” while writing Full Path
6.       Html Page may be like :
<body id=”aaaaa”>

   <div id=”bbbbb”>

   <div id=”cccc”>

          <a id=”dddd” class=”1111”>

          <ul id=”eeee”  target=”2222” href=”5555”>

  <div id=”ffff”>
               
Syntax in IDE:
Xpath=//branch/branch [ @property=’value’ or contains ( @property, “value”) ]
In the above example :
1.   Branch or Node – body , div , a , ul ,img
Note : Each Node value will have  many properties and many values .Therefore always start with a node value or "*" along with its relate property and value (Ex ://a[@target='_new']  or //*[@target='_new']  )
2.   Property – id , class , target
3.   Value – aaaa , bbbb , cccc , dddd , 1111 , 2222 , eeee , ffff ,5555

Syntax in Selenium (Eclipse Java):  
   ( Note -"Syntax in Selenium IDE" is only used to create Xpath and the below syntax is the usage of Xpath created using IDE )
Syntax :
WebElement oObject_Name=Driver_Object.findElement(By.xpath("Created Xpath Goes here ,starting from '//'"));
Example : 
oDriver=new FirefoxDriver();
oDriver.get("https://URL_Here");
WebElement oObject=oDriver.findElement(By.xpath("//branch/branch [ @property=’value’ or contains ( @property, “value”) ]"));

1.     Using Full Path
 xpath=//body/form/div[7]/div/div[2]/div/div[2]/ul/li/a
(The page usually start with <body> , therefore the foremost parent will always be “//Body” while writing Full Path )
Selenium Code :
 oDriver=new FirefoxDriver();
oDriver.get("https://www.mouthshut.com");
oTitle=oDriver.findElement(By.xpath("//body/form/div[7]/div/div[2]/div/div[2]/ul/li/a"));
2.     Using Last()
xpath=//body/form/div[7]/div/div[2]/div/div[last()]/ul/li/a
3.     Using Full Path+ @ attribute
·         xpath=//body/form/div[7]/div/div[2]/div/div[last()]/ul/li/a[@class='']
·         xpath=//body/form/div[7]/div/div[2]/div/div[last()]/ul/li/a[@style='background-color: transparent;']
(For Login Button)
xpath=//body/form/div[7]/div/div[2]/div/div[last()]/ul/li[2]/a[@target='_new']
4.      Using only @ attribute      (For Login Button)
xpath=//a[@target='_new']
(Which is equivalent to
xpath=//body/form/div[7]/div/div[2]/div/div[last()]/ul/li[2]/a[@target='_new']    )
5.     Using Descendants
xpath=//div[@class='new-menu']/descendant::div[@class='fr']
6.     Using keywords
xpath=//a[contains(@href, "javascript:__doPostBack(")]
xpath=//a[contains(@id, "ctl00_ctl00_ctl00_ContentPlaceHolderHeader_ContentPlaceHolderFooter_litSignUp")]



7.     And Operation
xpath=//a[contains(@id, "ctl00") and contains(@href,"javascript:_")]


8.     using position()
xpath=//div[@class='tdltaln']/div[position()=2]/ul/li


9.     Using starts-with keyword
xpath=//a[starts-with(@href, "https://graph.facebook.com")]
10. OR (|) condition
xpath=//a[@id='ctl00_ctl00_ctl00_ContentPlaceHolderHeader_ContentPlaceHolderFooter_litSignUpLink' or contains(@href,"javascript:__doPostBack")]

 xpath=//a[contains(@id,"ctl00_ctl00_ctl00_") or contains(@href,"javascript:__doPostBack") ]
 xpath=//a[contains(@href,"javascript:__doPostBack") or contains(@id,"ctl00_ctl00_ctl00_")]

11. Going 1 step back  
     Traversing from child to parent use    "/.."
12. Going back multiple steps or reverse tracing ( ancestor:: )
Ex :If user "ancestor::div" , then all the ancestor elements are highlighted with "div" node

  Back Trace to first occurrence of div element 
 //*[text()='Biological Sciences']/ancestor::div[1]
13. Going to specfic child element from parent node:( child:: )
Simialr to just "/ut[1]"
//*[text()='Biological Sciences']/ancestor::div[1]/child::ul[1]
 
14. Wild Card “*”
xpath=//*[@id="ctl00_ctl00_ctl00_ContentPlaceHolderHeader_ContentPlaceHolderFooter_litSignUpLink"]
15. Nth element
xpath=//ul[@class='login']/*[1]


16. No child
xpath=//img[count(*)=0]  

17. Last Second or Last But one 
xpath=//div[@class='dvaligncenter']/div[last()-1]//a

Examples for Xpath
xpath=xpathExpression: Locate an element using an XPath expression.

1. xpath=//img[@alt='The image alt text']
2. xpath=//table[@id='table1']//tr[4]/td[2]
3. xpath=//a[contains(@href,'#id1')]
4. xpath=//a[contains(@href,'#id1')]/@class
5. xpath=(//table[@class='stylee'])//th[text()='theHeaderText']/../td
6. xpath=//input[@name='name2' and @value='yes']
7. xpath=//*[text()="right"]
8. xpath=//*[@id='view']/*[not(@selected='selected')][1]
9. xpath=//*[text()='Biological Sciences']/ancestor::div[1]
10. xpath=.//*[local-name(.)='th' or local-name(.)='td']
Xpath summary
1.Path
    1. Full
    2. Full+attribute
    3. Attribute
    4. Wild Card(*)
    5. Recent ancestor "/.. "
    6. //a[6]
    7. div[3][contains(@id,'dvheader')] -goto 3rd element and fetch if it has dvheader similar to AND
    2.Functions
    1.  position
    1. [Last()]  //[Last[]-1]
    2. [Position()= 42]
    3. count
    1. text
    1. [starts-with(@,””)] -- Used For Dynamic Elements
    2. [contains(@,””)] -- Used For Dynamic Elements
    3. [text()=””] --text
    3.Logical
    1. And
    2. or
    3. not


  1. Navigation
  2.  Descendants::div[1]



  3. ancestor::div[1]

    Gradle : Debugging Gradle Project

    Gradle : Debugging Gradle Project



    Since my last Analysis I found fairly less information on Debugging Gradle in my line of work which is specifically on Automation .

    So the most convenient way was Debug using TestNG rather than Gradle .As I prefer using TestNg as my Automation Framework over Junit so there will be Testng.xml in the project folder (or similar xml file ).


    One can directly Start debugging  by :Rt ck on testng.xml > Debug As >TestNg


    If you are getting any error make sure you do these.Assuming you are using Eclispe
    1. Make sure you have plugin TestNg installed to eclipse .If not then goto Help>Market Place>Enter "testng" and search.
    2. Select testNG for Eclipse and click on Install >Select all options > restart Eclipse after installing
    3. goto  Project (title bar) > Clean
    4. Rt ck on Project > Properties >Java Build Path>Add Library > Select TestNG >Ck on OK

    Now user should be able to Debug for Gradle projects using Testng as well using Rt ck on testng.xml > Debug As >TestNg .

    Java : Exceptions (try catch)


    Java : Exceptions (try catch)



    1. Creating and Catching an Exception
        public void crossFingers()
        (
            try{
                Object.takeRisk();
            ) catch (BadException ex) // "ex" can be any variable
                System. out.println ("Aaarqh! ") ;
                ex .printStackTrace () ;
            }
        }

        public void takeRisk () throws BadException {
            if (abandonAllHope) {
                throw new BadException();
            }
        }
    ---------------------
    2. A finally block - runs regardless of an exception or even if the catch has a return statement
       
        try (
            turnOvenOn();
            x.bake () ;
        }catch (BakingException ex)
            ex.printStackTrace();
        }finally { //    runs regardless of an exception or even if the catch has a return statement        
    turnOvenOff();
        }
       
    3. Multiple try catch

        try {
            throw new IOException();
            }catch (FileNotFoundException f){
               
            }catch (IOException  e){
                System.out.println(e);     //output :     java.lang.NullPointerException
                e.printStackTrace;        //output :    java.io.IOException at package.Test.main(Test.java:74)
                                       
            }catch (Exception e){        //Catches all sorts of Exception should be placed LAST
                                        //If passed 1st any catch block belowing will be skipped
            }finally{
            }
           
    4. Multiple catch Using OR (|)
            try {
            do something ;
            }catch (FileNotFoundException | IOException e){ //Catch executes when either of the 2 exception occur
           
            }
           
    5. What you can do inside catch block ?
        -    e.printStackTrace()
        -    e.getmessage();
        -     log.error("Ops!", e); //Using logging framework like logback or log4j
        -     "USER CAN DO ANY OPERATIONS"
       
    6. What is Throwable t ?
        -    In normal cases we should always catch sub-classes of Exception.
       
        Example :
            try {
            do something ;
            catch(throwable t){ //"throwable" is super class of exception
               
            }
