I wanted to take a moment to express my heartfelt gratitude for the incredible tutorial you provided on API testing. Your clear explanations and detailed examples have helped me gain a deeper understanding of this important aspect of software testing. I truly appreciate the effort you put into creating such informative and engaging content. Your teaching style is exceptional, making complex concepts easy to comprehend. The way you broke down the client-server architecture and explained the role of APIs as mediators between front-end and back-end applications was particularly enlightening. Thanks to your tutorial, I have learned so much and feel more confident in my ability to perform API testing. Your dedication to sharing knowledge and helping others is truly inspiring.

Hi, thank you so much sharing these valuable videos. i have a question, i tried validating the cookies but I don't see any cookies being generated and because of that my test failed. may i know why cookies are not getting populated in the field?

[@ankitkeshri7089]

For me also , Cookies are not getting generated in the Response after hitting the API ..

[@karthika8610]

Did you find an answer to it?

[@dslmusic]

Guys, where can i find the pdf file in the video?

[@Endrju91]

About the topic of asserting the data types. I have following issue. I have even literally rewrritten test API from last episode. No matter what I do, the assertions do not work, as my response is not treated as an object but as an array. I get the response embedded in the [ ] additionally and postman says that test is failed because i expect the array to be an object. As I say, I have even rewritten 1:1 whole json file and still get this error. For me to work, I must use the allocation of the array element to have assertions working >>> pm.expect(jsonData[0]).to.be.an('object'). Also, despite defining the ID and number as the numbers, they are converted by postman to strings. As a result, the schema test fails once i generate the schema where it says - response type = object and id type = integer. I have 1:1 same json file as you have... If i change obviously first one to array and id type to string - works perfectly then

[@SineQuaNon1]

Can JSON Schema validation be explained better? A big no! Thanks for this clear explanation.

[@ghaithalali8372]

Hello sir I extend my sincere thanks for your wonderful efforts on this great explanation You are truly a wonderful person. I rewrote the document you explain from, and I was wondering if you would allow me to share it with my fellow learners?

[@saisanthoshnaidu]

Thank you so much.. Can you please provide us the document on chai assertion library.

[@harishreddy3195]

Nice explanation sir. 👌👌

[@sdetpavan]

Thanks

[@reaperxvi967]

Hate to say in this way, but most of these things will be covered during unit testing...If you guys are going to do full QA testing then mostly you will be doing manual testing because normally QA testing will not consider the verification of status code or header, you need to go fetch some data from some shitty database and manual check it against the API response...So buckle up, if you are in API testing then you need to test mostly manually, hardly there is any automation.

Thank you so much ! you are amazing. I'd like to ask a question concerning Json schema please. Since, do we have to use data type validation and Json schema validation assertions in postman or only Json schema will be sufficient, since the latter is also validating the data type. Thank you

Hello Sir, Great work sirji by yoy Your teaching technique is truly awesome, I am actually from a non-technical background but after watching your video I feel I am a full technical and knowledgeable person now I am trying to learn the Postman tool for the last few days, I have created the API database on my local machine, and I used all assertions but I have a problem with the cookies assertion coz I did not get any cookies on my postman tool, then how can I verify or test the cookies?

You did it very well and its a best tutorial which I have ever come across so far, thank you so much and keep motivating us pls. I have one clarification pls, can we skip data type validation of the values in the response if we do schema validation? I believe this would do all the field type validation. Please confirm
