How write API Tests with Postman in 3 easy steps

[@thomasfranz4826]

Very smart guy, this is how it should be. He speaks normaly, you can learn something because his speech has beginning and end with idea inside. Thumbs up!

[@geryvanegas1]

Your videos are a blessing, thank you VERY MUCH. I'm gonna be the first one to answer the challenge on the video: pm.expect(jsonData.headers["Cache-Control"]).to.eql("no-cache"); I had a hard time finding out why a dash was not accepted as a JSON variable, even that challenge was very instructive. thanks again.

[@pogothemonkey7461]

Valentin, could you please comment on this? I would like to know where I can find the information/theory that explains what to do in this case, meaning, the logic behind putting the [square brackets] because without looking for the answer I would never have guessed my way past the error message (due to my parameter not being "accepted").

[@amanpathania]

@@pogothemonkey7461 "Cache-Control" has a "-" and in order to pass cache control as a single value, you would have to use ["Cache-Control"]

[@bolexi7902]

Thank You for this one, I never needed to search elsewhere :)

[@anna-iz5op]

It doesn't work for me. "headers" is faded and I get an answer: Your test name | AssertionError: expected undefined to deeply equal 'no-cache'.

Thanks for the detailed explanation. Can we write a pre request script to upload an image file as binary in the Body of the request? I have an api in which I upload the image binary in the body before sending the request. I'm trying to validate this through script. Could you please guide me how to write the script for this. Thank You.

You're welcome! You can't access the filesystem from scripts.

do you have to use JavaScript for your test or can you use other languages?

[@vdespa]

Great question. With Postman you can only use JavaScript.

[@randy7425]

@@vdespa Are there other API testing tools/platforms that you know of that do not use JavaScript? I myself, am use to using python for automation tests, and would rather not have to learn a new language...thoughts?

[@randy7425]

If you don't want to learn JavaScript, forget about Postman. You need to use another tool. Writing API tests in Postman is rather easy. You can learn really fast.

I like postman but still don't see the value in the javascript testing. If i e.g. write my api in Golan, why shouldn't i test it using Golang native testing libraries like Ginkgo? When i gave the postman testing i try i stumbled upon very basic scenarios where the testing from the app is not working for me. Imagine testing an endpoint that creates a user. If i fill in my test with a demo user name and run it twice, the API will respond the second time with an error code because this user is already existing. I am not able to run a setup or teardown functions that actually cleanups my test database for every unit test.
