Integration testing is focused on detecting defects while there is an interaction taking place between integrated components or units. In unit testing, the modules are used for testing purposes and then these modules are tested and combined in integration testing. Integration testing tools take the integration testing process a notch higher thus improving the overall efficacy of the testing process. In this article, you will get to know the ten best integration testing tools.

What is Integration testing?

It is a testing method where individual modules of a software program are combined and tested as a group.

Following are the 10 best Integration Testing tools:

1. Rational Integration Tester: This tool provides a scripting free environment and development is possible for integration projects and SOA messaging tests. Integration related issues are resolved by this tool with the help of agile development and iterative processes. Code-free, reusable stubs can be created by this tool and testing can go on even if some components are being missed.

2. Protractor: This tool is specifically used for Angular and AngularJS applications. On top of WebDriverJS, this tool is built. WebDriverJS uses specific drivers, native browsers to interact with the application. Protractor has an open-source automation framework.

3. FitNesse: It is a fully integrated standalone tool and can be used to collaborate with business stakeholders. It is an open-source project. Separate installation is not required for this tool, only the java jar file can be downloaded.

4. TESSY: This tool is used to perform integration and unit testing of embedded software. The code coverage for an application can also be identified with this tool. The interface of the function is analysed and thus the variable used for that function is determined.

5. Validata MSG: It provides an automation testing framework and is used for the testing of SOA, ATM, SWIFT and Generic Interface. The integration testing is simplified and efforts are reduced by this tool. Real world business scenarios can be simulated by this tool.

6. LDRA: Code analysis for critical applications can be automated by this tool. This tool can also be used for compliance standard verification for different organizations. It is an open platform and by using the LDRA tool suite, integration tools can be built. It also provides dynamic analysis and static analysis over different platforms.

7. VectorCAST/C++: By using this tool, each module or unit is independently tested to ensure that individual components are working as expected. At a later stage of the integration testing process, these components are combined and verified to know whether all the integrated modules are working properly.

8. VectorCAST/Ada: It can be easily integrated with other tools such as Green Hills, IBM Rational etc. By using VectorCAST/Ada’s code generator, drivers and stubs are automatically created. For automation of regression testing, the existing test cases can be utilized.

9. Smart Integration Test Accelerator (SITA): The generation of test data and test design can be accelerated by this tool. It is a cost-effective tool because test data and test cases can be reused. It can be easily integrated with other tools such as HP ALM, IBM Rational etc.

10. Citrus: This tool provides the necessary validation for XML, JSON, response data and plain text messaging requests. It is an open-source tool through which a sequence of messages can be set. Error messages can be easily created and also messages can be easily received and sent.

Conclusion: If you are looking forward to strategic advice on integration testing from an implementation perspective and also want to know what are the tools that can best suit your project needs, then just get connected with a top-notch software testing services company and expect feasible solutions that work.
