Selenium: Open Source Automation Tool

Selenium

As I have mentioned I am trying to explore the selenium. So I will more talk about selenium web driver or selenium 2.0.

Other topics like Selenium history and RC, touch and go manner!!

Let’s start....

Selenium is an open source test automation suite used for automating web-based applications. It supports automation across different browsers, platforms and programming languages.

Benefits:

Selenium is open source, there is no licensing cost for its usage.
Scripting can be done in most of the widely used programming languages like Java, C#, Ruby and Python
It supports most of the popular browsers like Chrome, FireFox, Internet Explorer, Opera and Safari.
Selenium IDE component of Selenium suite provides record and playback feature using which non-programmers can also write automation scripts.
Selenium Grid helps in parallel and distributed testing.

Limitations:

Selenium does not provide desktop application automation support.
Web Services - REST or SOAP cannot be automated using selenium.
Selenium webDriver requires programming language requirement for script creation.
For performing common tasks required in automation like logging, reading-writing to external files we have to rely on external libraries.

Components of Selenium Suite:

Selenium is basically suite which has multiple testing tools/Component->

Selenium IDE - Selenium IDE is an add-on of Firefox browser that provides record and play back functionality.

Selenium RC - Selenium Remote Control (RC) is officially deprecated by Selenium. It used to require an additional server for running the automation scripts and had many limitations.

Selenium WebDriver - By far the most important component of Selenium Suite. It provides different drivers for different browsers and supports multiple programming languages.

Selenium Grid - Selenium Grid is also an important part of Selenium Suite. It helps in distributed running of selenium tests in parallel across multiple remote machines.

“Selenium RC and WebDriver” combined are popularly known as Selenium 2.

Selenium RC alone is also referred to as Selenium 1.

Selenium RC and Web driver interfaces where we can plug-in different browser drivers like the Internet Explorer and Chrome to support cross-browser testing.

Eclipse and Selenium IDE help us for creating automation scripts

Selenium 3

Selenium 3 is an advanced version of Selenium 2. It is a tool which is focused on automation of mobile and web applications. Stating that it supports mobile testing, we mean to say that the WebDriver API has been extended to address the needs of mobile application testing.

Next, now we move to Selenium WebDriver, Setup and script creation.

Happy Testing!!!

Pacing Calculation in Load runner

Today i will share my understanding on “Pacing”. Usually people take pacing as think time only. I will try to explain both terms first Think time and Pacing, both are a kind of “wait” or “delay” in terms of time but still both differ from each other. Think time: Think Time is the time or delay which user can take between two actions For example, User opens a URL by pressing “Enter” and login page appears but to enter user name or password user is taking some time like copying from other place or remembering it or something like that. This wait or delay we can term as think time in load runner. Think time can be inserted by user in script or captured by tool itself Whereas, Pacing is the delay between two iterations of test. We can give pacing time by using “Runtime Settings” of load runner tool. We can calculate Pacing/Think...

MI Listener in LoadRunner

In a regular LoadRunner load test scenario (not over a firewall), The Controller has direct access to the LoadRunner agents running on remote machines. This enables the Controller to connect directly to those machines. When running Vusers or monitoring applications over a firewall, this direct connection is blocked by the firewall. The connection cannot be established by the Controller, because it does not have permissions to open the firewall. LoadRunner solves this problem by using a communication configuration based on HTTPS or secured TCP/IP. This configuration uses the standard SSL port on the firewall (port 443). The MI Listener is a component that serves as router between the Controller and the LoadRunner agent. When the LoadRunner agent connects to the MI Listener, the MI Listener keeps a listing of the connection to the agent using a symbolic name that the agent passed to it. When the Controller connects to the MI Listener, it communicates to the MI Li...

Mobile Web(Http/HTML) Protocol IN Loadrunner

Today i will share my learning on performance testing performed on mobile application. We can use Load runner tool for mobile based applications. HP LoadRunner 11.50 has two new protocols for helping to record mobile applications: · Mobile Application – HTTP/HTML : recording scripts at the transport level for both browser-based mobile applications and native mobile applications, that communicate with their servers over HTTP · Mobile TruClient: recording scripts for browser-based mobile applications through the browser-based user interface. This protocol is based on Ajax TruClient, using a browser modified to emulate the mobile browser. These protocols are independent of mobile operating systems, so will work on different versions of iOS, Android, Windows Mobile, WebOs (Palm), Blackberry, etc. Let’s see the picture behind the scene: We can run the p...

Performance Testing of Documentum

Before starting details of how to do performance testing on Documentum I will try share a basic of Documentum so you can get an idea why we need a different approach while doing performance testing on it. What is Documentum? Documentum is content management software that provides management of document content and attributes. Documentum product is a three-tier, client-server system built on top of a relational database. Documentum components comprise the following: · Content Server - Manage access to the metadata stored in the relational database and the Content files, usually stored in the file system · Webtop/Wdk Server - J2EE-based web application framework Behavior behind the scene: An applet is invoked at the client side when a file within the docbase is accessed and while files are imported into a docbase. Applet/UCF client being client side Java applic...

Run Vugen script using command prompt

We can also run or replay our Vugen script using Dos Command Prompt (CMD) " LoadRunner install dir" \bin\mmdrv.exe -usr "path to .usr file" Note: LoadRunner install dir: Path of directory where Loadrunner has installed Hope this will help you guys. Happy Exploring!!!!

Heap Dump : how to generate heap dump

Heap dump is important when it’s come to performance testing. Let’s start with what is heap in an application. Heap: Heap is dynamically collective amount of data /memory in partially binary sorted tree structure. But we need to loop up on heap in term of memory. Heap is part of memory where memory for objects assigned dynamically. Heap dump : Heap Dump is snapshot of memory at certain point which contains below mentioned information: -information of java objects -information of java classes or we can define as A heap dump is a textual or binary representation of the Java heap which is usually written to a file. Heap dump is always helpful to analyze memory leak or high usage of memory of java application. There are various tools which help us to generate the heap dump. We can also generate heap dump without using tools. What we require is JVM (Java Virtual Machine)on system. There are various vendors for JVM but let’s concentrate on Sun JVM. ...

Record scripts on mobile applications in LoadRunner

Record scripts on mobile applications in LoadRunner : As LoadRunner 11 in Patch 3, Mobile App (HTTP/HTML) protocol added which can help us to record scripts of mobile apps. There are three recording options in the recording Wizard: 1.Record and Analyze Traffic - Use mobile sniffer agent to capture traffic and then analyze. This allows Vugen to connect to the mobile agent on the server or localhost and carry out the business process for recording. 2. Analyze Traffic - Analyze traffic using existing capture file to generate script. This allows Vugen to scan a pre-captured network traffic (WinPcap) file and generate the code based on the traffic. 3. Record Emulator - Record script using a mobile device emulator. This allows Vugen to record an emulator installed on the Vugen machine. With this option, you need to verify that you are able to bring up the emulator and navigate to a URL outside of Vugen to make sure the emulator settings are correct.
