Robot Framework vs behave: What are the differences?

Introduction In this article, we will compare and highlight the key differences between Robot Framework and behave. Both Robot Framework and behave are popular automation testing frameworks that support behavior-driven development (BDD) approach. While they share some similarities, there are notable differences in terms of syntax, language support, and flexibility.

1. Syntax: One of the main differences between Robot Framework and behave is their syntax. Robot Framework uses a keyword-driven syntax, which is easy to read and understand for both technical and non-technical users. On the other hand, behave uses Gherkin syntax, which is a natural language style syntax that is quite popular in BDD frameworks. This makes behave more suitable for collaborative work with stakeholders who may not have a technical background.

2. Language Support: Another key difference between Robot Framework and behave is the language support they provide. Robot Framework supports a wide range of programming languages including Python, Java, C#, and others. This allows users to write test cases in their preferred programming language. On the other hand, behave is primarily designed for Python, and its language support is limited to Python only.

3. Flexibility: Robot Framework is known for its flexibility and extensibility. It provides a rich set of libraries, plugins, and integrations that allow users to enhance its functionality and customize it according to their needs. This makes Robot Framework suitable for various types of testing scenarios and automation needs. In contrast, behave is a more focused framework that is specifically designed for BDD. It provides a set of built-in features and predefined steps for BDD, but it may lack the flexibility and customization options compared to Robot Framework.

4. Reporting: Robot Framework has a built-in reporting feature that provides detailed and customizable reports for test execution. It offers various reporting options such as HTML, XML, and text reports, which can be easily integrated into CI/CD pipelines. On the other hand, behave does not provide a built-in reporting feature. Users need to rely on third-party libraries or plugins to generate reports for test execution.

5. Test Case Structure: Robot Framework organizes test cases into test suites, test cases, and keywords. Test suites can contain multiple test cases, and test cases can contain multiple keywords. This hierarchical structure provides a clear organization of test cases and easy maintenance. In contrast, behave organizes test cases into feature files, scenarios, and steps. Feature files contain scenarios, and scenarios contain steps. This structure allows users to write test cases in a more narrative style, but it may be less flexible compared to Robot Framework's structure.

6. Community Support: Robot Framework has a large and active community of users and contributors. It has been around for many years and has a wide range of resources, documentation, and community forums available to users. This makes it easy to find help and support when needed. On the other hand, behave has a smaller community compared to Robot Framework. While it still has resources and documentation available, the community support may be relatively limited.

In summary, Robot Framework and behave are both powerful automation testing frameworks that support behavior-driven development. However, Robot Framework's keyword-driven syntax, wide language support, flexibility, built-in reporting, hierarchical test case structure, and large community support make it a more versatile choice compared to behave.
