Adding dependencies to maven for selenium

To add dependencies in maven project for running selenium tests, we can add dependencies under dependencies section as shown below:

1. Go to https://mvnrepository.com

2. Add Below dependencies:

a. TestNG

<dependency>
    <groupId>org.testng</groupId>
    <artifactId>testng</artifactId>
    <version>6.13.1</version>
    <scope>test</scope>
</dependency>

b. Selenium-java

<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-java</artifactId>
    <version>3.8.1</version>
</dependency>

c. Selenium chrome driver

<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-chrome-driver</artifactId>
    <version>3.8.1</version>
</dependency>

3. All the other dependencies related to selenium can be found at:
http://www.mvnrepository.com/artifact/org.seleniumhq.selenium

4. The dependencies are associated with the tests and downloaded at m2 folder in users folder

Sending keys in selenium

In Selenium, we are send specific keys from the keyboard like Enter or F2 on WebElement using import org.openqa.selenium.Keys as shown below:

import org.openqa.selenium.Keys

WebElement.sendKeys(Keys.ENTER)

Below is the list of enum constants defined for enum Keys, which we can send on an element in selenium:

ADD 
ALT 
ARROW_DOWN 
ARROW_LEFT 
ARROW_RIGHT 
ARROW_UP 
BACK_SPACE 
CANCEL 
CLEAR 
COMMAND 
CONTROL 
DECIMAL 
DELETE 
DIVIDE 
DOWN 
END 
ENTER 
EQUALS 
ESCAPE

Arrays in Java basics for selenium

1. We can assign value to an element in array as shown below:

testing[3] = 43; or all the elements can be defined in a go like shown below:
int[] testing1= {10,20,30,40,50,60,70,80,90,100};

2. We can extract all the values in an array using for each loop as shown below:

 int[] testing1 = { 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 };
 for (int test : testing1) {
     System.out.println(test);
 }

3. The same information can be extracted using for loop can be found as shown below:

for (int i = 0; i < testing1.length; i++) {
     System.out.println(testing1[i]);
 }

4. Using length property, we can find the size of any array


e.g. System.out.println(testing1.length)

4. We can pass an array as a parameter to a method, and also return value from a method:

5. We can sort an array in ascending order using sort();

Arrays.sort(testing1);

6. We can fill values in all the array elements using fill() menthod 
Arrays.fill(testing1, 385);

7. We can compare two arrays using arrays.equals

boolean isArrSame = Arrays.equals(testing1, testing);
System.out.println(isArrSame);
