Grinder and soapUI

Java based testing tools

What is Grinder?• The Grinder, a Java Load Testing Framework• It easy to run a distributed test using many load injector

machines• It is a open source and easily available

•Originally developed by Paco Gómez and Peter Zadrozny•Philip Aston took ownership of the code, reworked it to create The Grinder 2•Shortly after began work on The Grinder 3

Key features•Generic Approach•Flexible Scripting Tests•Distributed Framework•Mature HTTP Support

Capabilities

• Load Testing • Capacity Testing• Functional Testing • Stress Testing

Getting started

• The Grinder processes • Tests and test scripts • Network communication • Output

The Grinder processes

The Grinder processes (cont…)– Worker processes

• Interpret Jython test scripts and perform tests using a number of worker threads

– Agent processes • Manage worker processes

– The console • Coordinate the other processes • Collate and display statistics • Script editing and distribution

Buzz Words Used• Test – is a unit of work against which statistics are

recorded. Tests are uniquely defined by a test number and also have a description

• Thread – Each worker process has a number of worker threads we can define thread as number simultaneous instances requesting the server.

• Run – A single execution of a test script is called a run.

How do I start The Grinder?• Create a grinder.properties file• Start the console• Start the agent process• Set the Script directory in Console• Distribute Script files across agent processes• Run the test• Analyze the results

What is soapUI?• soapUI is a free and open source desktop

application.• Used for inspecting, invoking, developing,

simulating/mocking and functional/load/compliance testing of web services over HTTP.

•soapUI was initially released to Sourceforge during September 2005.•Since the initial release, soapUI has been downloaded more than 950,000 times •The soapUI project is currently headed by a Swedish company Eviware Software AB since 2006

Key features• inspecting Web Services• invoking Web Services• developing Web Services• Web Services Simulation and Mocking• Functional, Load and Compliance testing of Web Services• Uses Groovy as scripting language

Capabilities• Functional Testing• Load testing• Web service mocking

What is mocking?• Rapid Web Services Prototyping• Client testing/development• Test Driven Development

Getting Started

• Download the latest soapUI tool from http://www.soapui.org• Install it according to the instructions on your system. • Create WSDL file describing the service• Create and Run the test case with different steps

Groovy• Agile and Dynamic model• Builds upon strengths of Java• Inspired by languages like Python, Ruby and Smalltalk• Almost zero-learning curve for Java developers• Increases developer productivity• Simplifies testing • Integrated with java • Generates Java bytecode

Groovy and soapUI• Groovy is an essential part of soapUI• Groovy is used in soapUI primarily as a control step• Groovy can access test steps through the testRunner instance.

def request = testRunner.testCase.getTestStepByName( “LoginProperties" );def property = request.getProperty( “UserName" );println property.value
