Replace XPath with Css selector

If you know css selectors, those are much more easier (and will work fine with IE without any problem ) than xpath even though they can't replace entire xpath.


Consider below HTML tags

 <div id="firstDiv">This div tag has static id </div>

 <p id="paragraps_dynamic_1234">This p tag has dynamic id</p>

 <a onclick="doThat()" title="doThatOperation">This a tag has multiple attributes</a>

 <h1 name="heading1" value="headName">This is heading</h1>


<div>
<input type="text" id="username" name="username"> 
<input type="password" id="password" name="pwd"> 
</div>

<h2 id="propertyUserData">This tag is for starts-with example</h2>

Tag	XPATH	CSS SELECTOR
div	"//div[@id='firstDiv']"	"div[id='firstDiv']"
p	"//p[contains(@id,'paragraps_dynamic_')]"	"p[id*='paragraps_dynamic_']"
a	"//a[contains(@onclick,'doThat') and @tile='doThatOperation']"	"a[onclick*='doThat'][tile='doThatOperation']"
h1	"//h1[@name='heading1' and @value='headName']"	"h1[name='heading1'][value='headName']"
input	"//div/input[@id='username']"	"div > input[id='username']"
input	"//h2[starts-with(@id,'propertyUser')]"	"h2[id^='propertyUser']"

By seeing above locators we can conclude some points regarding css selectors

• Using css selector we can access particular node or immediate child of any node
• Can combine as many conditions as we want for single node.
• Can achieve starts-with, contains functionality using ^,* symbols respectively. 
• We can't traverse back using css selector.
• We can't go to  the siblings also (preceding as well as following)

For running Junit 3.x test cases from command prompt you need use below command

java -cp /usr/java/lib/junit.jar junit.textui.TestRunner [test class name]

Example Program

TestCaseA.java

package test;

import org.junit.Test;
import org.junit.After;
import org.junit.Before;


public class TestCaseA
{
   @Before
   public void beforeMethod()
   {
       System.out.println("Before method..");
   }
 
   @Test
   public void JUnit4Test()
   {
      System.out.println("In test method");
   }
 
   @After
   public void afterMethod()
   {
      System.out.println("after method");
   }
}

Execution from command prompt

java -cp junit-4.10.jar;test\TestCaseA.class; org.junit.runner.JUnitCore test.TestCaseA
