Running jmeter scripts in FF & IE browser

FF:

windows:
Jmeter - bin folder - find out system.properties file and add below line

webdriver.gecko.driver=C:\\Users\\Kranthi\\Desktop\\AA-Perf\\new\\geckodriver.exe

yes you need to add Firefox config file in the Test plan of jmter - no modifications required!

for mac:

>> jmeter -Dwebdriver.gecko.driver=/path/to/geckodriver

----------------------------------

IE:

only one version driver works in IE:

IEDriver  2.53.1 version of 32 bit IE driver. No other versions will work.

Program - Given an array A[] and a number x, check for pair in A[] with sum as x

hasArrayTwoCandidates (A[], ar_size, sum)
1) Sort the array in non-decreasing order.
2) Initialize two index variables to find the candidate 
   elements in the sorted array.
       (a) Initialize first to the leftmost index: l = 0
       (b) Initialize second  the rightmost index:  r = ar_size-1
3) Loop while l < r.

Why WebDriver driver = new ChromeDriver() ?

Below is WebDriver Interface & Respective class implementation architecture.

ChromeDriver driver = new ChromeDriver(); // Lot of methods from parent calss RemoteWebDriver

vs

WebDriver driver = new ChromeDriver(); // we can access only few methods from WebDriver Interface & SerchContext Interface

Ex: Advantage of interface

Public List getList(){
       return new ArrayList<String>()
}

We can return any implemented class for any method which has return type as interface
