Top 10 Integration Testing Tools to Write Integration Tests

Overview of the best Integration Testing Tools and Frameworks:

There are different levels of testing and one most important level is “Integration Testing” which combines different units or modules and tested as a group. It also tests the interface between modules and identifies critical defects which are caused due to the integration of different modules.

The goal of integration testing is to ensure that individual modules are working as expected after combining them with other modules. Many organizations either use combined unit tests or end to end functional workflow tests used for Integration Testing.

It is always good to perform frequent integration testing so that it ensures that after combining modules the integration works perfectly. In the current market, various Integration Testing tools are available which assists the organization to create a framework to build integration testing suites.

Top Integration Testing Tools to Write Integration Tests

Let’s begin with top integration test tools!

#1) VectorCAST/C++

VectorCAST C++

Vector Software’s VectorCAST tool popular for performing both unit and Integration Testing. Here, each unit or module is tested independently to ensure that individual components are working as expected without any dependency. Later during Integration Testing these components are combined together and verified that all integrated modules are working properly as a full combination.

Vector’s tools operate based on the idea that unit tests are executed as single components and integration tests are a combination of unit tests into a logical module and then executed as a group.


  • VectorCAST/C++ tool is used by developers who are creating their embedded software using C or C++ programming language
  • It is used to streamline the test procedure and used to automate unit and Integration testing
  • VectorCAST/C++ provides highly effective unit and integrated test solution
  • It validates safety and business critical embedded systems
  • The test solution provided by VectorCAST/C++ is widely used in financial industries, medical devices, industrial controls, railways.

#2) VectorCAST/Ada

Vector Software has another popular tool VectorCAST/Ada used by developers for developing a project using Ada programming language. It also provides automated test solution for the unit and Integration testing and used for validating the safety and critical embedded systems.

With the help of VectoCAST/Ada, unit testing can be performed locally or use target simulator. Individual components or modules are created and a code is generated. Drivers are used to simulating the functions of the code which is being tested and stubs are used in the function which is called by code which is being tested.


  • It can be integrated with multiple other tools like IBM Rational, Green Hills
  • Stubs and drivers created automatically using VectorCAST/Ada’s code generator
  • Existing test cases are utilized to automate regression testing
  • For automatic test case creation, decision path technique is used
  • High-risk code can be highlighted using code complexity analysis

#3) Citrus


Citrus is a test framework written in Java that assists in automated integration testing of message based application and data formats. Citrus validates for JSON, XML and plain text messaging request and response data.

Consider an example in which application under test is available on the application server. This application interacts with Citrus using various message transports like SOAP, HTTP, and JMS. In this case, Citrus acts as a both client and server side and simulate the request and response messages.


  • Citrus is open source and licensed under Apache License 2.0
  • Set sequence of messages
  • Create error messages
  • Message Header Validation
  • Sending and receiving messages
  • Wait for message and trigger another message
  • Supports integration testing for message transport connectivity
  • Validation of XML response
  • Validate existence of data

Now a day’s many organizations are adopting business-oriented architecture. The traditional integration testing method like bottom-up approach requires huge efforts to create test data.

Wipro’s Smart Integration Test Accelerator (SITA) helps you to overcome these challenges. This tool helps to accelerate the generation of Test Data and Test Design.


  • Test data and Test Design activities gets automated
  • Automated test data covers many other critical business scenarios which in turns reduces the defects in production or UAT
  • Cost effective due to reusability of Test Data and Test Cases
  • This tool can be integrated with other tools such as IBM Rational, HP ALM etc

#6) FitNesse


It is fully integrated standalone which makes it an excellent tool to collaborate with business stakeholder. FitNesse is an open source project and the code base is neither own the company nor by any individual. A lot of information shared by the FitNesse community as it’s an open source tool.


  • FitNesse is an Open Source
  • FitNesse does not require separate installation, only download the java jar file and its ready to use
  • It provides support to variety of languages like Java, C#, Python
  • For any software project, FitNesse allows validating the requirements with actual software implementation

#7) Rational Integration Tester

Rational Integration Tester

Rational Integration Tester is an Integration Testing Tool which was earlier known as Green Hat. IBM has acquired Green Hat in 2012.

With IBM’s Rational Integration Tester you will get a scripting free environment and development is possible for SOA messaging tests and integration projects. Rational Integration Tester prevents integration problems with the help of iterative and agile development processes. The tool is now a part of Rational Test Workbench.


  • It creates code-free, reusable stubs so testing still continue even if some components are missing
  • Rational Integration Tester provides Functional, Regression and Integration testing to move integration testing earlier in the development lifecycle
