Automate Rest GET Call using HTTP Client - Rest API Automation - Part-3

[@Abhi_AdventureAndFitnessFreak]

I was searching for quite a long time to learn and do hands on RestAPI, today i finally able to do everything from skretch and the way Naveen you explained is really awesome. My confidence has grown up now and i guess i will be ready for interview once i complete the whole couse. A tutor like you is a blessing for all of us.

[@raisawate2812]

I have Started my career very late in automation Testing Such videos with end to end explanation are helping hands for me thanks Naveen

[@sarojjha9243]

Thanks a lot, Naveen. In the end, you told its little difficult since differing from selenium concepts. My question is ... If one gets a trainer like you and a right attitude to learn like a small schoolboy ...no concept sounds difficult...

[@Anaris13]

Man, I love how you are explaining at a framework level!

[@naveenautomationlabs]

Glad it was helpful!

[@devrajukkingatti9748]

@@naveenautomationlabs very much

[@PoojaPanchal12]

I had no idea we could automate api testing in the above manner, thank you so much for enlightening all of us. You are right that one should manually try how api methods work and then it is easier to understand how it can be automated.

[@thaleshbhardwaz]

So much informative content, everything is covered in depth. Thanks a lot Naveen. God bless you for all this.

[@anandandy411]

Thank you sir for such a nice video and the beauty is explaining in very simple way that a non IT person will also able to get the concept very clearly. This will help us a lot. Once again thank you Naveen AutomationLabs👍

[@naveenautomationlabs]

It's my pleasure

[@AvinashRadhakrishnan-o2o]

Thanks Naveen.....The Session was Excellent and it helped me understand the concepts very well. Please keep up the excellent work. Big Salute.

[@harshpatel160]

You are doing really a great work for Students like me. But one thing if you can do, just increase font size and try to write coding part in full screen. So it make easy to watch specially code. Expecting this it's really amazing platform to learn.

[@raghavendraaroli2562]

[@desertstar7664]

I would recommend everyone to switch to IntelliJ as their IDE if you are following Naveen. It is much easier to follow his tutorial and practice it along with in IntelliJ as in comparison to Eclipse. IntelliJ intuitively fixes any error and suggests recommended changes. It is fast and easy to use IDE.

[@adityadeshmukh8927]

Thank you is small word for the effort that you are putting.

[@srivuttar]

Thanks a lot Naveen. I really enjoyed going through your videos. You have really very good content in Rest API. You explained in details by putting your hard efforts so that anyone can understand.

[@dwarakchandra5629]

@Here, sometimes the Json Object will throw an exception "JSON Text must begin with "{", when your response starts with "[", you can use the below code to overcome that jsonrespString = EntityUtils.toString(chresp.getEntity(),"UTF-8"); int i = jsonrespString.indexOf("{"); jsonrespString = jsonrespString.substring(i); JSONObject respJson = new JSONObject(jsonrespString);

Hi Naveen, Thank you for providing us with all the tutorials with simple and easiest way to learn. I have an issue to hit the GET call to the provided URL through eclipse. But when I try the same using the postman it is working fine. Im using a settings.xml for maven built. Is there anything that I have to do as proxy in the eclipse. I am getting error as timeout issue. Please help.

[@laeeqahmed1980]

I see that the videos are for accessing already developed APIs. Have you done videos on actual building APIs. e.g. with databases.

[@raghavendranithin895]

Need help, i get an error when i use the code -- " JSONObject responsejson = new JSONObject(reponseString); " -- it says the constructor JSONObject is undefined.. Please reply at the earliest.

[@PankajSharma-pl3nq]

Hello Naveen, Nice Explanation as always. I have one doubt. At 34:35 why did you had to extend the TestBase Class in your GetAPI Class? Is it just to inherit the prop object? We could have achieved same result without extending base class and by having the prop object as static ?

[@subhamthemusicalguy8851]

Awesome tutorial. Please make some tutorial on rest api automation with python and pytest. This is very much demanded in marcket

[@amolnawale2177]

Hi Naveen, I am following your tutorial to build the RestClient using HTTP Client for API testing. I am getting SSLHandshakeException while running my API tests. We have 3 environments QA, Demo and Prod. Demo and Prod are using https protocol whereas QA was previously using http and now has been upgraded to use https protocol. My API tests are working fine on the Demo and Prod environment, but failing on the QA environment giving the below exception: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target at sun.security.ssl.Alerts.getSSLException(Unknown Source) at sun.security.ssl.SSLSocketImpl.fatal(Unknown Source) Our DevOps team has updated the SSL certs on the QA server, but it didnt help either. Have you ever encountered such SSL Exception and if you are aware of any solution for the same.

Hi Naveen I tried executing the code but after running it is showing "java.io.FileNotFoundException: C:\Users\lps02\eclipse-workspace estapi\src\main\java\com\qa\config (Access is denied)" error. Can u please help here?

[@rajesho9772]

Awesome bro 😇

[@SuyashNande]

As you are using TestNG, can't we assert the response instead of printing it into console. I think, then the validation is also automated. it will be justified with the automated testing.

[@naveenautomationlabs]

obviously we have to validate JSON object also. It's there in the next video, I have explained how to validate JSON response using Json API. here u go: kzbin.info/www/bejne/o5S4oXucm75nbaM

Hello Naveen this is great tutorial, how do we get the code means your all class file is there any location where we can get and use it very easily.

Thank You!!

[@pushkarnagarkar1006]

Hi Naveen, Thanks for this video. I am getting null in the responseString. Can you help here?

[@pavangupta5417]

Hi Naveen, I have a question Why we automate API using JAVA Code or others ,if we have already tools like Postman, SOAP UI, We can use those tools and automate the API with very less time.

[@RajChahalNsit]

Hi Pavan , tools can be helpful for manual testing , or might even have features to run multiple API call in a batch . but when we talk about a framework JAVA usage will always be required. We cant be having a separate framework for API and other front end.

[@jkheaven7117]

@Naveen for API Automation , rest Assured or HTTP client which one is good?

[@naveenautomationlabs]

Jk Heaven both are good. Httpclient APIs are easy to implement. Restassured is more like a bdd approach

[@jkheaven7117]

Naveen AutomationLabs , but in interviews they are asking about Rest API testing.

[@jkheaven7117]

What should we tell to the interviewer?

[@naveenautomationlabs]

you can mention both http client and rest assured. tell some other tools like postman, rest client etc.

[@jkheaven7117]

Naveen AutomationLabs please add post, delete and put request

[@ajinkyakholkute8203]

Same issue occurring to me as well

[@yasaswipara6912]

Using rest assured client, api automating is very easy.. Then why don't we go for rest assured Instead of httpclient??

[@ramki8973]

Hello Naveen. I am getting "javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure" from line "httpClient.execute.." in RestClient.get method. I am using jre1.8.0_251 and httpclient -4.5.12 and httpcore-4.4.13. I have even tried to ignore the SSL error by "creating the HttpClient using HttpClient factory methods and assign the ssl socket factory(TrustSelfSignedStrategy)". would be great if you can guide in this step. Unable to proceed with next episodes due to this error. Thanks!.

[@ramki8973]

Found the solution and thought it might help the others currently. SSLHandshakeException is solved by downgrading JDK/JRE version from 1.8.0_231 to 1.8.0_171. Now the connection is made successfully and the response is received.

[@vishantsworld9843]

I am getting the below error on executing the code, could any please help. org.testng.TestNGException: TestNG by default disables loading DTD from unsecured Urls.

Make sure you are using the same annotations as well, beforemethod and test should come from TestNg, maybe you have used Junit in the test.

Hi @Naveen AutomationLabs I followed the same code and i see that when i implement the same in my project one API gives 200 and the next get API gives 404.. i tried with several APIs but no use. Can you help?

in this case, u r doing some mistake. need to check ur APIs. it must also work in ur case. have u hit these apis manually using postman? can u share these apis with me?
