You are the most amazing faculty one can have ❤ undoubtedly you must be receiving alot of blessings and especially from those who can't afford but really want to learn. You are blessing for all !! Cant thank enough for your efforts and knowledge you are sharing.
My pleasure
Hi Soniabajaj
I never knew APIs but after watching this series, I have learned so much I can now start doing tests for APIs
So far you are the best teacher for all different technology on You Tube that I found. Thank you so much for what you do.
Welcome
The flow from start to end describes how much you are expert on Testing
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.
Best regards,
jalal Khan
I don't exact about the testing and postman after watching your videos, now am sure don't want another Channel for same course. This is enough for everything , Thank you so much , uploaded great videos ❤
All your lectures are highly informative. Great job.
Thanks
where do i find the document shown in this video, checked on site didnt find it
Thank you sir, I watched several videos about Postman, but this one is the best. Clear and very informative.
Welcome
You're a saviour honestly. Thankyou so much for explaining everything so clearly😇
You’re welcome
👍 thank you again to teach us validation section in very easy way..we ll oblised to you always.🙏

You are most welcome
Thank you sir from bottom of my heart you and your videos help me to get job on testing 😢
Every points and details are so precise thank you sir ❤❤❤❤
It's my pleasure
Hi sir currently I am working candidate in it this video's are very helpful to me. I pray to god to give much more healthy life for long time. thank you so much for giving this wonderful teaching stuff.
Welcome
One of the best tutorial available so far.
Glad it was helpful!
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
Hands off sir 🙌
I haven't seen this kind of teaching in my career so far. Thanks a lot for the free knowledge-sharing ❤
Sir, can you please provide us material or documents PDFs it helps a lot in practicing

Welcome
Thank you so much sir It's Amazing teaching Style ❤🙏🏽💐💐
Welcome
Hi sir. Your explanation is very easy to understand.
Thanks
thank you sir for such amazing lecture on postman , may lord bless you with abundance of health and wealth
sir one question why i didn't get ant cookies in my postman tool for testing them, please tell us as some of the students are not getting cookies.
Thank you Sir☺🙏
Same Here. I too didn't get any cookies in my Postman.
Sir, you provide excellent content for free on CZcams. However, when I start watching, I often feel irritated and find it challenging to learn new things, even though my intentions are to learn. How can I stay motivated and remain focused while using my laptop?
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.
Your class is great！thank you sir！
You are welcome
Learned some thing new . Thanks Sir
Glad to hear that
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?
For me also , Cookies are not getting generated in the Response after hitting the API ..
Did you find an answer to it?
good explanation sir it is very helpful for me
Glad to hear that
Respected sir, Thank you for your entire series.. It really helps alot.... Request you to please provide download link for the file.
Hello sir! Thanks for the course! I would like to ask you, how will we know which one to use?? (pm.response or pm.expect)
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

Nice Explanation 🙏
One request please cover the concept of mocking the api’s using mock server with as much as negative status codes.
Thanks in advance
Thank you Sir, God bless you and your family!!!
Welcome
Pls share the ppt, for future reference. Thanks a lot, you are an amazing teacher.
hello sir,where are you uploading the document and how to access it can you please tell? i have attained your java -selenium batch and going through the Api series now.
ya I have same query , did u find those ppts which he is explaining in the lecture ?
No@@snehalraut821
thank you sir
@sdetpavan sir I am facing similar errors for other validations as well. Even if the syntax is correctly given and Json file also correct.
Array contains the value test | AssertionError: the given combination of arguments (undefined and string) is invalid for this assertion. You can use an array, a map, an object, a set, a string, or a weakset instead of a string
Value of the fields test | AssertionError: expected undefined to deeply equal 1
Schema Valiation Test | AssertionError: expected false to be true
I'm so glad I found your CZcams channel. You are amazing teacher. Thank you very much for your work🙂
You're very welcome!
Your Videos are really helpful. I have a doubt... When testing cookies, I didn't get any cookies value under Cookies . Please clarify why? and when the cookies value are empty, then what kind of validations should we need to do Sir.. thank you so much
same issue
same issue any updates ?
@@hamzaniazi9186
Same issue. Any answer to it?
Sir hello. Can you send that document involved in 3rd class
Thanks for all your effort in training on testing field. Could you please provide video to clear ISTQB exam
Great explanation sir
Thanks
Sir thank you so much for your time and efforts its really easy to gain knowledge by just going through your playlist.
But for this API series you have given link in description to access related documents but while opening that it says content are no longer present.
Can you or anyone from here please share documents again or any other available link ?
I want to know how I will validate my response value which is changed on every api call. Like how can I write a test case for that? It will be really helpful if you try to explain it in your next video.
I am having this below assertion error. AssertionError: expected undefined to be an object while running the test script for testing response body. What will be the solution for this?
Guys, where can i find the pdf file in the video?
Thanks for detailed descriptions of postman tests .
Welcome
How to find postman documents ? which you used in this video sir? I am from pakistan.
sir file is just an Image not pdf to download? plz provide pdf for same
Sir..nice teaching..
But please add documents in description page 😭
I want to do complete ecommerce domain project with end to end testing practically...can you tell how much fess is there for that
awesom teaching sir waiting for other courses . Please do many videos on python frmae works and AWS as well sir.
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
Please share the pdf if possible
Also how many more session will be coming?
Pls share the document sir whatever you shown in the session, it would be very helpful to learn .
Thanks for your time sir❤❤❤❤
Always welcome
Amazing!!! Thank you❤
You're welcome
Hi Sir, Thanks for providing so much detailed understanding of API testing . Please can you share the link from where we can get all the documentation from POSTMAN
i am also looking a link for download document
Hello SIr, I have a query like, When there is a huge data while getting response back, I'm getting 500 status code. Is there is any solution for it, like can we increase response waiting time for that?
Nice explanation sir.

hello Sir, where I can find documents, I am not able to find in description.
Hello sir. Thank u so much for ur sessions and classes. I am incredibly happy with wat i am learning from dis platform. I have recently completed the course sessions on manual testing for beginners..i am a complete new to it world. I am also preparing all the possible expected interview queries.
My main fear is , i am an engineering student who passed out a decade ago exactly. Presently being a home maker and a mother of kid can I expect any company dat can really hire me or PPL like me. I have been hesitating to apply anywhr becoz of did reason.. what i am expecting from u sir , is to plz guide me if der is any kind of break through from dis situation. Can I really work in dis field can i axpect if der is a company out der u recive and give opportunity to PPL like us..
I really want to start my career now after a decade . Is it possible and how and from whr can i pursue???
Thank u sir

Hi Sir,
I am not able to get the notes of the video. I have clicked on the document link, it is showing uploaded content does not exists.. Can you please guide me if there are any other ways of accessing it.
Hello Sir, Where can we have the documentation used in the API videos ? Can you make videos on C# and Selenium C# using Visual Studio ? I really like your videos.
when I run json-server students.json it says file students.json not found, even though the file is present in the same directory
Sir, do we have to do any changes under students.json file for Cookies? As i am unable to get options under Cookies.
add your own
1.- below the send button click on cookies
2.-add your domain (URL) to the add domain field and click Add domain
3.-change the name and value to what you want
Thank you so much for your time and efforts sir.
But for this API series I am not able to find the documents can you please share it ?
Hi Sir,
I am Kranthi from Hyderabad, I am following your channel for API testing. I am unable to find API testing material, Could you please provide me the material if possible. It would be very helpful for me.
Thankyou for the video... one thing I'm trying to understand is that when you have more records in your response (e.g you have 5 students returned in the response) and you want to validate the contents of the courses array, but the values are different for each student... one student has java & selenium, and another student has only java... is postman just validating the first record?
Thank you so much sir for API serias.
I have to add some API points in my resume which API points should I mention in my resume .
Where can i download the notes from of these lectures ? Pls share.
I'm from madhya pradesh ❤❤❤❤ love you sir
