  Faker is an Open Source Python package that generates synthetic data that could be used for many things such as populating a database, do load testing or anonymize production data for development or ML purposes. Generating fully random data isn't a good choice: with Faker you can drive the generation process and tailor the generated data to your specific needs: this is the greatest value provided by Faker. This package comes with 23 built-in data providers, some other providers are available from the community. The available data providers cover majority of data types and cases, but it is possible any way make the generated data more meaningful by implementing a custom provider. Faker supports Python 3.6+ and it is available for installation through PyPI or Anaconda.  Here's a code example that shows how to implement a custom provider to generate synthetic data following the structure and constraints as for this Kaggle  dataset related to a restaurant data with consumer...

If you want to learn about the basics of creating a load testing plan for an InfluxDB instance using Apache JMeter please read my step-by-step walkthrough on DZone. Enjoy it!

Apache JMeter ( http://jmeter.apache.org/ ) added support for MongoDB since its 2.10 release. In this post I am referring to the latest JMeter release (2.13). A preliminary JMeter setup is needed before starting your first test plan for MongoDB. It uses Groovy as scripting reference language, so Groovy needs to be set up for our favorite load testing tool. Follow these steps to complete the set up: Download Groovy from the official website ( http://www.groovy-lang.org/download.html ). In this post I am referring to the Groovy release 2.4.4, but using later versions is fine. Copy the groovy-all-2.4.4.jar to the $JMETER_HOME/lib folder. Restart JMeter if it was running while adding the Groovy JAR file. Now you can start creating a test plan for MongoDB load testing. From the UI select the MongoDB template ( File -> Templates... ). The new test plan has a MongoDB Source Config element. Here you have to setup the connection details for the database to be tested: The Threa...

Starting from today I want to share part of my knowledge about SoapUI (as promised at the end of the post http://googlielmo.blogspot.ie/2013/12/dance-into-groovy.html ). I used this tool for some years in order to perform load testing and integration testing and I found it really helpful. SoapUI is a tool that allows any kind of functional and not functional testing. Despite its name it is not limited to the SOAP protocol and to web services only: you can perform tests for different protocols (HTTP/S, REST, JDBC, AMF, etc.) and application layers. It was born to be used for SOAP web services testing, but then it evolved to be a general purpose testing tool. It comes in two editions, Open Source and Pro. The first one is free to use and you can modifiy the source code too, according to the LGPL license. The second one is commercial and closed source. In this post and the following I will refer to the Open Source edition. The companies I worked for in the last years didn't want to ...
