Selenium RC is a main selenium project which is sustained for a longer period of time before the selenium WebDriver which came into existence. The Selenium RC will be in use as webDriver provides strong features and continue to develop the scripting using the RC. It provides to code the command for automated web application UI tests supports full power of programming languages like java, C#, perl and python create more complex tests read write operations on files, querying a database and emailing test results.
Selenium RC Architecture
Selenium RC will work in such a way that the client libraries will communicate with all the selenium RC Server that is passing with each Selenium command to the browser using Selenium core is JavaScript commands.
The browser will run the selenium commands using its JavaScript interpreter
Selenium RC will come into the parts:
- The Selenium Server will launch and kills browsers. It interprets and executes the selenese commands. There are properties of HTTP proxy by intercepting and validating HTTP messages forwarded between the browser and application which is under test.
- There are client libraries has interface between one programming languages and the other as Selenium RC server.
RC scripting:
Consider a sample script using Selenium Remote Control. When we use http://www.calculator.net/ for knowing Selenium RC. We can calculate using ‘Percent calculator’ the present under the ‘Math Calculators’ module.
Step 1: Start selenium Remote control.
Step 2: When launching Selenium RC, we have to open Eclipse and create a “New Project” as
Step 3: We have to enter the project name and click “Next” button.
Step 4: Verify the source project,libraries and output folder and click “finish”.
Step 5: By right clicking on the project we choose to “Configure build path”
Step 6: Properties for ‘selrcdemo’can be used up. These transfer to ‘Libraries’ tab and click ‘Add external JARs. Select the selenium RC jar file we have downloaded and it would appear.
Step 7: The referenced Libraries which are shown
Step 8: It is used to create new class file by performing a ‘right click’ on ‘src’ folder and select ‘New’>>’class’.
Step 9: We enter the name of the class file and also enable ‘public static void main’.
Step 10: It has Class is created under the folder structure.
Step 11: Now it is time for coding. The following code has comments that are embedded in it to make the readers understand has been put forth.
Package selrcdemo;
Import com.thoughtworks.selenium.DefaultSelenium;
Import com.thoughtworks.selenium.Selenium;
public class rcdemo {
public static void main(String[] args) throws InterruptedException // This is Main function
{
Selenium selenium1 = new DefaultSelenium(“localhost”, 4444 , “Mozilla Firefox”, “http://www.Calculator.net”); // Instatiate the RC Server
selenium1.start(); // Start
selenium1.open(“/”); // Open the URL
selenium1.windowMaximize();
// Click on Link Math Calculator
selenium1.click(“xpath = .//*[@id = ‘menu’]/div[3]/a”);
Thread.sleep(2500); // Wait for page load
// Click on Link Percent Calculator
selenium1.click(“xpath = .//*[@id = ‘menu’]/div[4]/div[3]/a”);
Thread.sleep(4000); // Wait for page load
// Focus on text Box
selenium1.focus(“name = cpar1”);
// enter input in Text box 1
selenium1.type(“css=input[name = \”cpar1\”]”, “10”);
// enter a input Text box 2
selenium1.focus(“name = cpar2”);
selenium1.type(“css = input[name = \”cpar2\”]”, “50”);
// Click Calculate button
selenium1.click(“xpath = .//*[@id = ‘content’]/table/tbody/tr/td[2]/input”);
// By verify if the result is 5
String result = selenium1.getText(“.//*[@id = ‘content’]/p[2]”);
if (result == “5”) {
System.out.println(“Pass”);
} else {
System.out.println(“Fail”);
}
}
}
Step 12 – We will execute the script by clicking ‘Run’ Button.
Step 13: Here the script will be starting to run and the user will be able to see that the command history under the ‘Command History’ Tab.
Step 14: The final state of the application is shown. The percentage will be calculated and it is displayed the result on screen.
Step 15: The output is tested will be printed on the Eclipse console as shown below as we have printed output to console.In real time the output to an HTML file or a simple Text file.
