will testng initiate as many webdriver instance as test cases? - selenium

Question

I am facing a problem of Selenium Grid and TestNG. My test scripts will NOT quite the browser until all the test class are executed.
I've configed 5 Chrome instance running on my Selenium Grid, then below is my xml file
<suite name="BrowserTest">
<test name="Test1" >
<parameter name="browserName" value="chrome"/>
<classes>
<class name= "Pagetest" />
</classes>
</test>
<test name="Test2" >
<parameter name="browserName" value="firefox"/>
<classes>
<class name= "Pagetest" />
</classes>
</test>
<test name="Overview Page Test on ie, English" >
<parameter name="browserName" value="ie"/>
<classes>
<class name= "Pagetest" />
</classes>
</test>
</suite>
Here is my test scripts
public class Pagetest {
private WebDriver browser;
public PateTest( String browser){
// create a browser instance.
}
#AfterClass (or #afterTest)
public void afterTest() throws Exception {
System.out.println("this test is done");
this.browser.quit();
}
#Test
public void test1(){
this.browser.get("www.google.com");
// doing some login stuff
}
}
Now when I am running my test, testNG will create 3 chrome webdirver instance one by one (with running the test). but after the 1st test is done, the browser instance of 1st test is not quited until all 3 tests are done, then all the 3 chrome instance are quited almost at the same time. What I want is after the 1st test is done, it's browser instance is quited, then the 2nd test case is started, did I do something wrong or how should I change my code?

Try using threadlocal it would help when you are even running tests in parallel
public ThreadLocal<WebDriver> driver=null;
#beformethod()
public void setUp
{
driver = new ThreadLocal<WebDriver>();
driver.set(new ChromeDriver());
return driver.get();
}
#AfterMethod
public void closeBrowser() {
{
driver.get().quit();
}
