August 8, 2018 liesbeek Leave a comment

If you are using Java maven project below are steps.

1. Open pom.xml file and add below dependencies.

<dependency>
	<groupId>com.googlecode.json-simple</groupId>
	<artifactId>json-simple</artifactId>
	<version>1.1.1</version>
</dependency>

<groupId>com.googlecode.json-simple</groupId>

<artifactId>json-simple</artifactId>

</dependency>

2. Create a java class and use below code

package helper;

import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;

import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
import org.json.simple.parser.ParseException;

public class JSONReadFile {


	public static void main(String args[])
	{
		JSONReadFile jsonReadFile = new JSONReadFile();
		jsonReadFile.getJSONUsingFileName("json/example1.json");
	}
	
	public void getJSONUsingFileName(String fileName) 
	{
	 String path = "src/test/resources/";
	 JSONParser parser = new JSONParser();
	 try {
         Object obj = parser.parse(new FileReader(path+fileName));

         JSONObject jsonObject = (JSONObject) obj;
         System.out.println(jsonObject);

         

     } catch (Exception e) {
         e.printStackTrace();
     } 
	}
	
 }

package helper;

import java.io.FileNotFoundException;

import java.io.FileReader;

import java.io.IOException;

import org.json.simple.JSONObject;

import org.json.simple.parser.JSONParser;

import org.json.simple.parser.ParseException;

public class JSONReadFile {

public static void main(String args[])

{

JSONReadFile jsonReadFile = new JSONReadFile();

jsonReadFile.getJSONUsingFileName("json/example1.json");

}

public void getJSONUsingFileName(String fileName)

{

String path = "src/test/resources/";

JSONParser parser = new JSONParser();

try {

Object obj = parser.parse(new FileReader(path+fileName));

JSONObject jsonObject = (JSONObject) obj;

System.out.println(jsonObject);

} catch (Exception e) {

e.printStackTrace();

}

3. Run the Java class.

1. How to open another tab and switch to it.

JavascriptExecutor js = (JavascriptExecutor) session.driver;
js.executeScript("window.open('https://www.google.com','_blank');");
ArrayList<String> tabs2 = new ArrayList<String>(session.driver.getWindowHandles());
session.driver.switchTo().window(tabs2.get(1));

JavascriptExecutor js = (JavascriptExecutor) session.driver;

js.executeScript("window.open('https://www.google.com','_blank');");

ArrayList<String> tabs2 = new ArrayList<String>(session.driver.getWindowHandles());

session.driver.switchTo().window(tabs2.get(1));

2. How to get the value of CSS locator from a DOM in the console

$("input[name='first_name']").value

1	$("input[name='first_name']").value

3. How to run any CSS or XPTH locator on the console using querySelector

var element = document.querySelector("button[value='180']")
element.click()

JavascriptExecutor js = (JavascriptExecutor) session.driver;
js.executeScript("document.querySelector(\"button[value='180']\").click()");

var element = document.querySelector("button[value='180']")

element.click()

JavascriptExecutor js = (JavascriptExecutor) session.driver;

js.executeScript("document.querySelector(\"button[value='180']\").click()");

How to get the YAML data and use it in Java

August 5, 2018 liesbeek Leave a comment

1. Create a YAML file. Below is the example

OnBoardingActivity:
getStartedButton: getStarted_btn

GetStartedActivity:
phoneNumberEditText: phone_number_layout
continueButton: send_sms

android: studio

2. Download snakeyaml jar file.
3. Create a java file.

import java.io.FileReader;
import java.io.IOException;
import java.io.Reader;
import java.util.Map;

import org.yaml.snakeyaml.Yaml;

public class YamlConfigRunner {

    public static void main(String[] args) throws IOException {
    		Yaml yaml = new Yaml();
    	    Reader yamlFile = new FileReader("./locators/Elements.yml");

    	    Map<String , Object> yamlMaps = (Map<String, Object>) yaml.load(yamlFile);

    	    System.out.println(yamlMaps.get("android"));
    	    System.out.println(yamlMaps.get("OnBoardingActivity"));
    	    
    	    Map<String, Object> map = (Map<String, Object>) yamlMaps.get("OnBoardingActivity");
    	    System.out.println(map.get("getStartedButton"));           
}
}

import java.io.FileReader;

import java.io.IOException;

import java.io.Reader;

import java.util.Map;

import org.yaml.snakeyaml.Yaml;

public class YamlConfigRunner {

public static void main(String[] args) throws IOException {

Yaml yaml = new Yaml();

Reader yamlFile = new FileReader("./locators/Elements.yml");

Map<String , Object> yamlMaps = (Map<String, Object>) yaml.load(yamlFile);

System.out.println(yamlMaps.get("android"));

System.out.println(yamlMaps.get("OnBoardingActivity"));

Map<String, Object> map = (Map<String, Object>) yamlMaps.get("OnBoardingActivity");

System.out.println(map.get("getStartedButton"));

}

Run the program. Below is the output
studio
{getStartedButton=getStarted_btn}
getStarted_btn
