Assertible vs. Cerberus Testing vs. Postman vs. Python Comparison Chart

The easiest way to test and monitor your web services. Gain confidence in critical infrastructure by using Assertible's automated QA tools to test and monitor your web services across deployments and environments. Assertible provides a reliable first line of defense against web service failures by providing simple and powerful assertions to test and monitor your APIs and websites. Lower the number of false positives in your automated QA tests and be confident your APIs are healthy. Keeping your tests up to date can be a burden, but with Assertible you can automatically sync your API tests with the latest changes in your specification. As you add and update responses, parameters, headers, and more, updating your Assertible API tests is as easy as clicking sync. Assertible integrates with the tools you're already using and lets you do things like execute your web app tests when you push code to GitHub, or send alerts to Slack if failures happen.

The collaboration platform for API development. Simplify each step of building an API and streamline collaboration so you can create better APIs—faster. Postman is a collaboration platform for API development. Postman's features simplify each step of building an API and streamline collaboration so you can create better APIs—faster. Quickly and easily send REST, SOAP, and GraphQL requests directly within Postman. Automate manual tests and integrate them into your CI/CD pipeline to ensure that any code changes won't break the API in production. Communicate the expected behavior of an API by simulating endpoints and their responses without having to set up a backend server. Generate and publish beautiful, machine-readable documentation to make your API easier to consume. Stay up-to-date on the health of your API by checking performance and response times at scheduled intervals. Provide a shared context for building and consuming APIs, and collaborate in real-time.
