General conversation about the use and development of Tavern. We also have a Gitter chat for questions and If you have any feature requests or if you’ve found a bug you can raise an Better explanations of why a test failed.Validation function are more flexible and easier to use.Cleaner test syntax which is more intuitive, especially for non-developers.On top of MQTT testing, Tavern has several other advantages over PyRestTest which overall add up to a better developer experience: Pyresttest is a similar tool to Tavern for testing RESTful APIs, but is no longer actively developed. On the other hand, Tavern is free and open-source and is a more powerful tool for developers to automate tests. For example, Tavern does not have a GUI nor does it do API monitoring or mock servers. Tavern does not do many of the things Postman and Insomnia do. A simpler, less verbose and clearer testing language.Seamless integration with pytest to keep all your tests in one place.Testing of MQTT based systems in tandem with RESTful APIS.A full-featured Python environment for writing easily reusable custom validation functions.However, specifically with regards to automated testing, Tavern has several advantages over Postman: Postman and Insomnia are excellent tools which cover a wide range of use-cases for RESTful APIs, and indeed we use Tavern alongside Postman. Tavern is a focused tool which does one thing well: automated testing of APIs. Why not Postman, Insomnia or pyresttest etc? Interested in contributing to the project take a look at the Test MQTT, or you can mix MQTT commands inline with HTTP tests to test more Tavern is not just limited to testing HTTP APIs however - it can also be used to Test_::Get some fake data from the JSON placeholder API PASSED Rootdir: /home/taverntester/myproject, inifile: Platform linux - Python 3.5.2, pytest-3.4.2, py-1.5.2, pluggy-0.6.0 - /home/taverntester/.virtualenvs/tavernexample/bin/python3 Then figure out what I can do to augment the weaknesses with other tools.$ py.test test_ -v = test session starts = I try to identify the strengths of each tool, and the weaknesses. Proxy for capturing the traffic and helping me document my testing.Proxy for ’extreme’ payload manipulation and fuzzing.Exporting collections to insomnia for easier experimentation with requests through a proxy.Data Driven testing from data files in Postman with the Runner and csv files.I also find the JSON filtering of result payloads in Insomnia quite useful. Burpsuite and Owasp Zap have different filtering abilities and different Fuzzers, and I like the option of switching between them all without losing testing focus and restarting the app. Often when I’m exploratory testing I’ll want to use different proxies e.g. Postman will now route traffic through a system hook proxy like Charles or Fiddler, but it can be a little more troublesome to feed Postman through a proxy, and certainly is not as easy to toggle between proxies without exiting the Postman app. I use Insomnia because the preferences dialog allows me to easily feed Insomnia through an HTTP Debug proxy like Burpsuite or Owasp Zap. Insomnia makes working with API documentation easy as well since many of the API examples are presented in cURL I can copy and paste the examples into Insomnia for experimentation. I can then copy the cURL request from Postman and paste it into the URL bar in Insomnia which does a really good job of creating a request in Insomnia. Pros API penetration testing by Insomnia can be integrated into the CI/CD pipeline of projects. It is available for Windows, Mac, and Linux and has customizable API test flows. Kreya and BloomRPC are strictly working with gRPC. Plus, they have a lot of additional features for easy writing of API tests. HTTP API testing in both tools is the primary function. I either export my Postman collection and import it into Insomnia as a Workspace, or I convert a Request in Postman to a cURL request using the code generation facility in Postman. Insomnia This is an open-source tool available from Kong that is mainly for creating REST or SOAP APIs. For Postman and Insomnia, gRPC is just one of the many features. When I find a ’thing’ and need to explore in more detail I move over to Insomnia. In Postman I build a collection with my main requests and examples. In this post I’ll describe, and show, how I do that. Are you a QA/QE and using Postman/Pew/Insomnia for testing your Rest API.
