Cucumber vs Detox: What are the differences?

Introduction

Cucumber and Detox are both popular testing frameworks used for testing the behavior of software applications. While they serve a similar purpose, there are key differences between the two.

1. Test Language: One of the main differences between Cucumber and Detox is the test language they use. Cucumber is primarily used for behavior-driven development (BDD) and supports writing tests in a natural language format called Gherkin. Gherkin allows for easy collaboration between technical and non-technical team members. On the other hand, Detox is mainly used for end-to-end testing and supports writing tests in JavaScript or TypeScript.

2. Test Automation: Cucumber focuses on testing the behavior of an application by using a set of predefined step definitions that can be customized as per the requirements. It allows for the creation of reusable steps that can be combined to create test scenarios. Detox, on the other hand, provides a set of out-of-the-box testing functionalities specifically designed for mobile applications. It has built-in mechanisms for interacting with native mobile elements and supports gestures like tapping, swiping, and scrolling.

3. Platform Support: Cucumber is a cross-platform testing framework and can be used for testing applications on various platforms like web, mobile, and desktop. It supports multiple programming languages and has integrations with different testing tools and frameworks. Detox, on the other hand, is primarily focused on testing mobile applications and provides extensive support for both iOS and Android platforms. It integrates well with popular JavaScript testing frameworks and tools like Jest and Mocha.

4. Accessibility Testing: Detox offers built-in support for accessibility testing, which allows for evaluating the accessibility of mobile applications. It provides APIs and utilities to simulate accessibility features like voiceover, accessibility font scaling, and inverted colors. Cucumber, on the other hand, does not have built-in support for accessibility testing and would require additional tools or libraries for performing such tests.

5. Parallel Execution: Detox provides functionality for parallel execution of tests, allowing for faster test execution and reduced testing time. It supports running tests in parallel on multiple devices or simulators simultaneously. Cucumber, on the other hand, does not have built-in support for parallel execution but can be integrated with other tools or frameworks to achieve parallel test execution.

6. Integration with Continuous Integration (CI) Tools: Both Cucumber and Detox can be integrated with popular CI tools like Jenkins, Travis CI, and CircleCI for running automated tests as part of a continuous integration and delivery pipeline. However, Cucumber has been around for a longer time and has established integrations with a wider range of CI tools compared to Detox.

In summary, Cucumber is a behavior-driven testing framework that supports natural language testing, works across multiple platforms, and provides extensive integrations. Detox, on the other hand, is a mobile-focused testing framework that offers out-of-the-box support for mobile gestures, accessibility testing, parallel execution, and seamless integration with JavaScript testing frameworks.
