Selenium is designed in a way to support and encourage automation testing of functional aspects of web based applications and a wide range of browsers and platforms. Due to its existence in the open source community, it has become one of the most accepted tools amongst the testing professionals.
Selenium supports a broad range of browsers, technologies and platforms. Selenium RC alone is also referred as Selenium 1. Being responsible for the testing of an internal Time and Expenses application, he realized the need for an automation testing tool so as to get rid of repetitive manual tasks without compromising with the quality and accuracy.
This IDE was capable of recording and playing back the user actions on a Firefox instance to which it was plugged-in. The tool turned out a great value and potential to the community. Its record and playback feature makes it exceptionally easy to learn with minimal acquaintances to any programming language.
With several advantages, a few disadvantages accompanied Selenium IDE, thus making it inappropriate to be used in cases of more advanced test scripts. Loopholes and restrictions which were imposed while using Selenium Core made it difficult for the user to leverage the benefits of the tool to its totality.
Thus it made the testing process a cumbersome and a far reaching task. Problem of same origin policy: The problem of same origin policy disallows to access the DOM of a document from an origin that is different from the origin we are trying to access the document.
So, In order to govern the same origin policy without the need of making a separate copy of Application under test on the Selenium Core, Selenium Remote Control was introduced.
While Jason Huggins was demoing Selenium, another fellow colleague at ThoughtWorks named Paul Hammant suggested a work around of same origin policy and a tool that can be wired up with a programming language of our choice. Thus Selenium RC came into existence.
Browser executes the commands using selenium core and sends results back to the selenium server Selenium server delivers the test results to the client library.
Click on image for enlarged view Selenium Grid With selenium RC, life of a tester has always been positive and favorable until the emerging trends raised a demand to execute same or different test scripts on multiple platforms and browsers concurrently so as to achieve distributed test execution, testing under different environments and saving execution time remarkably.
Thus, catering these requirements selenium grid was brought into the picture. Selenium Grid was introduced by Pat Lightbody in order to address the need for executing the test suites on multiple platforms simultaneously.
Step 2 In this step, Search for "pydev" in search box and then Click install In my system it is already installed. Step 3 Select the checkbox button. It says 'PyDev. After marking the checkbox, press 'Next'. Step 4 Now, in this step you will set preferences. With the help of preference option, you can use Python as per the project need. Click on "OK" button.
A new window will open when you click on 'OK' button. In this window, follow the following steps. Under interpreter dropdown, you select the option Interpreter-Python.
It helps in running Python scripts.
Also, set workbench time interval. When a build is performed, the workbench will automatically save all resources that is changed since the last build. Click on 'OK' button. When you click on"OK" button, it sets the default Python Interpreter.
It is just like you need to set java compiler for running a Java code. To change the interpreter name, double click on Python Tab.
Step 5 In this step, give the "interpreter name" and the "exe file name" of Python. Click on 'Browse' and find python. Click 'OK' button.
Step 6 Make a New Project in Python. You can see the new Python PyDev project is created. Step 8 Create a new Python package. After entering the name, click on "Finish" button. If you see in below screenshot, a new package is created. After creating a new package, the next step is to createPyDev Module. The module contains somePython files for initialization.
These files or functions from the module can be imported into other module. So, there will be no need to re-write the program again.
