What is Keploy

Keploy is an open-source, AI-powered tool designed to automate API, integration, and unit testing. It generates test cases and mocks/stubs from real API traffic, enabling developers to achieve up to 90% test coverage in minutes. Unlike traditional testing methods that require manual test creation and maintenance, Keploy leverages AI to record and replay API interactions, ensuring deterministic and reliable tests. This approach reduces testing time, improves code quality, and simplifies testing workflows. Keploy's unique value lies in its ability to automatically create and maintain tests, making it ideal for developers and teams seeking efficient and comprehensive testing solutions.

Keploy 's Core features

AI-Powered Test Generation

Keploy uses AI to automatically generate test cases and mocks from real API traffic. This eliminates the need for manual test creation, significantly reducing the time and effort required for comprehensive testing. The AI analyzes API interactions to create relevant test scenarios, ensuring high test coverage and accuracy.

Record and Replay API Traffic

Keploy records API traffic and replays it to create deterministic tests. This ensures that tests are repeatable and reliable, regardless of external dependencies or environmental factors. The replay feature allows developers to isolate and test specific API interactions in a controlled environment.

High Test Coverage

Keploy helps developers achieve up to 90% test coverage in minutes. This high coverage is achieved through automated test case generation and the ability to capture and replay a wide range of API interactions. This ensures that a significant portion of the codebase is tested thoroughly.

Open Source and Free

Keploy is an open-source tool, available under the Apache 2.0 license. This allows developers to use, modify, and distribute the software freely. The open-source nature promotes community contributions and transparency, ensuring the tool's continuous improvement and accessibility.

Integration with CI/CD

Keploy seamlessly integrates with CI/CD pipelines, enabling automated testing as part of the software development lifecycle. This integration allows developers to run tests automatically after code changes, ensuring that new code does not break existing functionality. This improves the overall quality and reliability of the software.

Deterministic Testing

Keploy's ability to record and replay API traffic creates deterministic tests. This means that tests produce the same results every time they are run, regardless of external factors. This consistency is crucial for reliable testing and accurate identification of bugs.

How to use Keploy

Install Keploy: Choose your preferred method (e.g., Docker, Kubernetes, or direct installation based on your OS) following the instructions on the Keploy website.,2. Integrate Keploy into your application: Add Keploy as a dependency to your project and configure it to intercept API traffic. This typically involves adding a few lines of code or configuration files.,3. Run your application: Start your application as you normally would. Keploy will automatically record API interactions and generate test cases and mocks.,4. Generate tests: Use the Keploy CLI or dashboard to generate test cases based on the recorded API traffic. You can specify parameters such as test coverage targets.,5. Execute tests: Run the generated tests within your CI/CD pipeline or locally to ensure your application's functionality is validated against the recorded API traffic.,6. Analyze results: Review the test results and use Keploy's reporting features to identify any issues or areas for improvement in your application's testing coverage.

Use cases of Keploy

API Testing Automation

Software developers use Keploy to automate API testing. They record API traffic, generate test cases, and integrate them into their CI/CD pipelines. This ensures that every API endpoint is thoroughly tested, reducing the risk of bugs and improving software reliability.

Integration Testing

Development teams use Keploy to perform integration testing. They record interactions between different components of their application, generate tests, and replay them to verify that the components work together correctly. This helps identify integration issues early in the development cycle.

Unit Testing

Developers use Keploy to create unit tests for individual components of their software. They record the interactions of a component with its dependencies, generate mocks, and use these mocks to isolate and test the component's functionality. This ensures that each unit of code functions as expected.

Regression Testing

QA engineers and developers use Keploy for regression testing. They record API traffic from previous versions of the software, generate tests, and run them after code changes. This ensures that new code does not introduce regressions and that existing functionality remains intact.
