Introduction to Selenium

Hi Friends................ :)

 Today we are going to look a famous testing tool Selenium. Selenium is a popular open-source web based automation tool. It is used fir automating web-based applications.

 It consists of,
1. Selenium Integrated Development Environment (IDE)
2. Selenium Remote Control (RC)
3. WebDriver
4. Selenium Grid
Advantages
Selenium is a suite of tools that helps in automating only web applications. You should have a basic understanding of Java or any other object-oriented programming language for using Selenium.It has capabilities to operate across different browsers and operating systems.
Selenium IDE -a Firefox plugin that lets testers to record their actions as they follow the workflow that they need to test.

 Selenium RC-was the flagship testing framework that allowed more than simple browser actions and linear execution. It makes use of the full power of programming languages such as Java, C#, PHP, Python, Ruby and PERL to create more complex tests.
Selenium WebDriver-is the successor to Selenium RC which sends commands directly to the browser and retrieves results.
Selenium Grid-is a tool used to run parallel tests across different machines and different browsers simultaneously which results in minimized execution time.

 Disadvantages
Supports only web based applications.
No IDE, so the script development won't be fast
Cannot access controls within the browser.
No default test report generation.

Hashing... First Step to Secure Software Programming

Image
Where it all started? Anyone in the field of programming wouldn't have missed the chance of implementing a login page. This login page might look very simple and straightforward. But in reality, it is not. What most of us would have done for our first login page is a simple string comparison for both username and password which might have already been hard-coded in the program. Some might have retrieved the username and password from the database and compared it with the user entering credentials based on roles. If we think about this scenario in a real-world enterprise or corporate level applications, the authentication procedure will not take place as simple as that. Authentication Authentication is all about ensuring that the system is being accessed by the correct user. Authentication plays a very important role in most of the systems or applications. The reason is to prevent the system from unauthorized access. Authentication methodologies 1. Username Password authentic...

Encryption to take secure programming a step forward

Image
[http://blog.trendmicro.com/wp-content/uploads/2012/03/Cartoon-2.jpg] What is "Encryption"? Why is it associated with secure programming? What are the benefits of encryption? These are questions to be evaluated in this blog post along with some interesting facts about encryption. As we all know hashing is a one-way process in which the plain text/input cannot be retrieved from the hash value. What if we want to get the plain-text from the hash value? What could be the solution? The solution is Encryption . Encryption Encryption is a technique used to convert a plain text into an encoded format or cipher-text which could be reversed back to the original plain text. Unlike hashing, encryption is a two-way technique. Fig 1: The flow of encryption Fig 2: Encryption/Decryption related details for the Fig 1 Since encryption is a two-way process it allows the users to retrieve the encrypted value back to its original text. This is very useful in terms...

RMI - Weather station

Image
Hi friends !!!! :) Today I like to share one of my projects with you..... It's basically a weather station  where weather readings are gathered and updated using RMI technology, Java Remote Method Invocation. The Java Remote Method Invocation (RMI) system allows an object running in one Java virtual machine to invoke methods on an object running in another Java virtual machine. RMI provides for remote communication between programs written in the Java programming language. Fig 1: RMI method invocation Since we have the theory background of RMI I thought of sharing my project in which I have implemented a very basic client-server program using RMI to pass information from server to the monitoring station. As we all know in a weather forecasting station we have to gather the weather readings and send them in a periodic manner to all the stations connected to the server. Through this we can invoke methods running in one Java virtual machine through an object running in a...
