8/8/2023 0 Comments Save postman collection![]() REST is a common pattern for making requests to and getting responses from an API (a server's or app's programming interface) over the web. Integrate Tableau management tasks into your existing workflows, and more. That means you can automate repetitive tasks, create automated workflows that behave differently based on the condition of your Tableau resources, The Tableau Server REST API enables you to create a script or program that performs the same actions you can take through the server UI. This should keep things more in-sync.Why would I want to use the REST API to manage my Tableau Server and resources? This way you can make sure that that API test payload/response bodies are in-sync with what's tested in the unit tests. Write a decorator or util that you can add to jest tests that registers an API test.Create the OpenAPI JSON Schema from /package/class-validator-jsonschema and extend it with examples and more validations.There's a lot that could be done to extend this. This doesn't fully automate our API testing (yet), but it does ensure that our API tests are in sync with the OpenAPI Spec file AND we don't have to touch a line of yaml. this file could contain some secrets so it's. You can take this file and import it into actual Postman and run the tests / hit the APIs in there:ĭepending on your level of customization. The newman library also has the option of exporting the new collection with all the tests. If the full API test is run, the output will look like this: I talk about some strategies at the bottom of this article for how to potentially make this more robust. This only protects against basic endpoint changes such as renames. This will make sure the extended Postman Collection is in sync with the generated OpenAPI spec. □ Notice how much faster npm run test is thanks to esbuild? □īut what if we don't want to deploy the API first? No problem! Instead of npm run newman:test use npm run newman:pr. Since the previous project automatically generated the OpenAPI spec, we just need to add two more commands to test the deployed API: npm run test ![]() For example you could check specific items in a json response using dot notation since they are simply evaluated directly. The src/newman/checks.ts file has the generators for those tests, and it's easy to see how these could be extended. The test interface's status and response values get turned into the string arrays used by newman/postman. How many times have you some string? 12 times.' The benefit of this is that all we need to do is have a bunch of string generators to produce the tests we want to run.Įach endpoint test we run is defined by the ApiTestConfig interface: export interface ApiTestConfig Postman tests are a little unnerving in that they just execute a list of strings as javascript for their test. This would break a PR's CI prior to getting merged anywhere. ![]() If that doesn't exist (for example if you rename an endpoint) the generator will return an error: > ts-node src/newman/newman.tsĮrror: Misconfigured test: Advanced Hello Check - /other/:hello/advanced It uses the test's path and method to find the corresponding test from the OpenAPI-generated file. This file uses a list of tests that it iterates through to generate the customized postman collection. □ Note: None of this has us editing json/yaml by hand! Everything is generated via code! □ Code Walkthrough
