What is Keploy?

Keploy creates backend API tests with built-in-mocks or stubs by recording your application network calls making your testing process not only faster than unit tests but also incredibly efficient.

To kick things off, let's dive into the fundamentals:

📽️ Record-Replay Complex API Flows

Turn API Calls into Test-Cases and Mocks

With Keploy, you can effortlessly record and replay intricate, distributed API flows as mocks and stubs. It's like having a time machine for your tests! ⏳

Keploy will record all API calls and their subsequent network traffic served by the application. You can utilize your favorite API management tools like Postman, Hoppscotch, or even Curl to generate test cases.

Keploy automatically mocks network/external dependencies for all CRUD operations with correct responses.

Once recorded, you have the flexibility to replay and simulate the same flow with mutations/write calls locally or within your CI environment without needing to connect to external services/dependencies.

No more data dumps, stubs, or mocks for dependencies like DBs, internal services, or third-party services like twilio, shopify, or stripe are required anymore. 💡

Idempotency guarantees are also not required in the application. Multiple Reads after write operations can be replicated automatically too. 🔄

🧩 Combined Test Coverage:

Run Tests with Mocks Anywhere You Like

Keploy has native integrations with your unit-testing libraries like go-test, jUnit, jest, pyTest. Keploy gives combined test-coverage and can also be integrated in existing CI pipelines easily within go-test, jUnit, jest, pyTest workflows.

Run tests with mocks anywhere you like—locally on the CLI, in your CI pipeline, or even across a Kubernetes cluster. It's testing wherever you want it! 🌍

♻️ Multi-Purpose Mocks

Re-Use Mocks for Testing Servers

Keploy generated dependency mocks can also be used as test case for the server. These tests can be used for use-cases like chaos testing, e2e testing, integration testing, api and regression testing. 🌟

🌐 Code-less EBPF Instrumentation

Network Layer Integration makes it Light-Weight

Keploy uses EBPF like a secret sauce to make integration code-less, language agnostic, and oh-so-lightweight. 🍲

🔍 Accurate Noise Detection

Eliminates random fields for Assertion

Keploy identifies noisy fields in the responses accurately like (timestamps, random values) to ensure high quality tests.

As the application serves the API, Keploy re-run that API request with the captured dependency mocks.

Keploy identifies differences in API responses, marking them as random/noisy fields. 🧐✅
