Introduction To TOSCA Testing Tool

About Testing Tool:
Software Testing tools are creating our lives easier and higher each day. Tools for defect management, Test case management have been already very popular, as far as the functional testing is concerned. Now comes the era of automation. Tools like QTP (UFT), RFT and Selenium were always a part of a hot discussion. To give these tools a tougher competition, the latest tool that is in very demanding nowadays and a hot topic of discussion is the TOSCA test suite by Tricentis.

  • Tricentis TOSCA is an automation tool for functional and regression testing of various software products. It also includes GUI, CLI (command line interface), integrated test management, and API. This tool was developed by TRICENTIS Technology & Consulting GmbH, the Austrian company. The tool is created in VB6, C#, and Java.

In today’s age of highly responsive and interactive software methodologies and processes where many organizations are utilizing some form of Agile methodology, test automation is evolving as a major requirement for most software projects. Test automation implies utilizing a software tool to run repeatable tests against the application that is to be tested. Selenium testing is an open-source testing tool used for automating the tests cases which carried out on web browsers. The major advantage for selenium over other testing tools is that there is no licensing cost (free) required for it.  

Tricentis Tosca is an agile enterprise software testing tool used to automate all the stages involved in test cases and offer comprehensive test management for software applications. This tool is based on the LinearQ(sm) methodology. The one feature of this tool which makes it gain an advantage over others is the model-based technique where an Application Under Test(AUT) model is created instead of scripts for test automation. The Tosca platform accelerates testing to keep pace with DevOps and Agile.

The company Tricentis took into consideration many ideas before building the right product. That outlook included Test script design, Test automation strategy, Test data design, and its generation and of course analytics. These aspects/idea’s help in thorough and rigorous testing of APIs and GUIs from a business perspective.

  • The most significant technologies which make it ahead from its peers include Model-based test technique and Risk-based test technique.
  • Model-based test Technique: One of the major features where this tool is gaining grip over other automation tools is due to its model-based technique where a model of AUT (application under test) is created instead of scripts for test automation. All the technical details about AUT i.e( application under test), test script logic and test data are separately saved and merged together at the time of test case execution. The central model gets updated at any moment, so change is done across all over in element of the application. This central model helps in removing ambiguity and a larger effort so that the test scripts that are responsible to test the updated element need not be recreated manually to reflect the change.
  • Risk-based test technique: This one is used to assess risk with respect to test cases and help in identifying the right set of test scripts and the risk impacted by them. Various black-box test techniques such as Equivalence Partitioning, Decision Box, boundary value testing and other methodology such as linear expansion, etc. are used to minimize the test script count while chances to increase the functional risk coverage. Once the test execution is completed, the reports related to technical, functional, business and compliance are collated and risks are measured based upon risk coverage.

This tool is used to test functionality as well as regression test scenarios and automate them without using test scripts. In addition, with the testing of automation functions, this tool includes integrated test management, a GUI (Graphical user interface), a CLI (Command Line interface) and API (application programming interface). This product or tool is developed by the Austrian company Tricentis Technology and  GmbH consulting based in Vienna. Tosca provides a one-stop solution to automate 30+ technologies in one time. Supported technology for Tosca on Tricentis website can be referred to find all the supported technology stack. Some of the common automation platforms include Web-based, Desktop based, Mobile based, Web services and Microservices, Database, Mainframes, SAP, etc.

Following is the difference between Selenium and Tosca by studying their features and comparing them.


  1. Selenium is an open-source automation testing tool. 
  2. It can be scripted in both Java and Python. 
  3. It has the support of some of the biggest software vendors who are taking or have taken steps to make selenium an intrinsic component of their browser. 
  4. Almost all your queries can be answered regarding the usage of selenium as it consists of a huge online open-source community. 
  5. You can write tests in the most recent languages as it is programming agnostic. It helps users to finish tests in less time and this will not be possible using manual testing. 
  6. Most of the mainstream browsers such as IE, Firefox, Chrome, etc, are supported by Selenium. It is free to use and there is no need to pay for the license as well.



  1. Tricentis Tosca breaks the barriers that are experienced with traditional software testing tools with the help of the industry’s most innovative functional testing methodologies. 
  2. Leading companies such as UBS, Orange, Lexmark, Deutsche Bank, Starbucks, BMW, Allianz, Toyota, Whole Foods, and HBO attain more than 90 percent test automation rates.
  3. It is recognized as the Industry Leader by top analysts.
  4. It reduces regression testing to minutes from weeks.
  5. With the help of model-based test automation, it maximizes maintainability and reuse.
  6. You can obtain insights into the risk of your release candidates with the help of Tricentis Tosca.
  7. You can achieve sustainable automation with the help of market-leading, proven methodology.
  8. Tosca is a paid tool but it’s user-friendly. You need not write any scripts if you use Tosca.

Key Features:

  • Business dynamic steering: The main aim of the TOSCA commander is to create an entire test dynamic and not just the input data. Without scripting test cases are created using drag and drop feature and after carefully adding validations. The test cases which are then made of dynamically provide for the business based description for manual and automated test cases. Because of this dynamic steering, the test cases can be designed, documented, automated so that it can be maintained by non-technical functional testers too.
  • One of the primary/essential features of TOSCA is the generation of dynamic, synthetic test data, automated business dynamic test case generation steering. Unified handling and executing test cases of functional and automated, GUI and CLI based test cases.
  • Test cases can be prioritized and weighted based on their importance and criticality. Hence, this feature enhances the reporting mechanism which impacts of technical weak points by trying to meet with the requirements.
