Prime 5 Instruments for Testing REST APIs and RESTful Net Providers in 2023

Whats up guys, In case you are a Java or net developer engaged on REST APIs and RESTful net companies and on the lookout for some instruments to check your APIs and net companies then you could have come to the suitable place. Earlier, I’ve shared the greatest books and programs for RESTful net companies and on this article, I’m going to share 5 superior however simply accessible and free instruments to check your REST APIs. These REST API testing instruments will allow you to to check your APIs as you construct, ranging from unit testing to integration testing after which totally automating your resting to create a regression pack. You can even use these instruments to work together together with your REST API through the growth part for fast checks. 

A few of you would possibly already accustomed to these instruments, instructions, and library in that case simply chip in and share your expertise in order that we are able to all study from one another. 

For those who ask me, I typically used the curl command for easy testing wish to see what information a specific REST endpoint return however for extra subtle testing I typically use instruments like Postman, RESTAssured, or SOAPUI. 

Anyway, with none additional ado, listed below are some instruments you should utilize to check your REST APIs or RESTful net companies, as we Java developer calls them. I may even add extra instruments and their examples as and after I discover them, however for now I’ve shared the instruments and assets for additional studying them. 

5 Greatest REST API Testing Instruments for Java Programmers in 2023

1. Curl 

That is my favourite software and nearly 50% of the time I exploit this. The primary motive for that’s as a result of I really like Linux instructions. The curl or cURL command lets you ship various kinds of HTTP requests e.g. GET, POST, PUT, and DELETE which you should utilize to check fundamental functionalities of your REST APIs as proven in my earlier article about testing REST APIs utilizing the curl command in Linux.

It additionally lets you set HTTP headers which implies you’ll be able to set Content material-Kind or Settle for header to check content material negotiation like I typically set Content material-Kind=”utility/json” to get a JSON response from the REST API.

For those who do not curl but then you’re lacking out huge time, not simply REST APIs the software lets you ship any utility which relies upon HTTP.

I’ve used curl previously to put in writing well being verify scripts that pings our net service, await a while, and report if it does not obtain any response. Basically, realizing Linux command helps lots and if you wish to study them, then the Linux for Freshmen course by Bogdan Staschuk on Udemy is an efficient place to begin with.

It is also feature-rich and helps each stage of the REST API lifecycle. By design, testing, and full manufacturing, Postman is there for quicker, simpler API growth—with out the chaos.

If you wish to study extra about Postman instruments for REST API Testing, I extremely suggest you be a part of Postman: The Full Information – REST API Testing course by Valentine Despa on Udemy. It is an incredible useful resource to successfully use the Postman software. 

3. RESTAssured [Best for Automation Testing]

As a Java developer, that is my most well-liked option to check REST APIs routinely. If I not doing any handbook testing utilizing curl or Postman then I exploit REST Assured to put in writing checks in Java for our REST APIs. It is like JUnit for REST APIs however a lot better.

In case you have labored in dynamic languages like Ruby, PHP, and Python then you already know that writing one thing in Java entails lots of ceremonies however RESTAssured handles that for you and it lets you write check in a transparent, descriptive language like whenever you name this relaxation service you anticipate this response code, this information, and so forth.

I strongly suggest to Java developer and automation tester to study RESTAssured for automation testing and if you happen to want assets then Relaxation API Testing (Automation) from Scratch -RestAssured Java course by Rahul Shetty on Udemy is an efficient place to begin with.

4. Resty

That is one other command-line software to check your REST APIs. It is nothing however a small script wrapper round curl that focuses on testing REST APIs. Simply set up this little software and supply and you can begin testing your REST APIs from the command line.

It’s carried out as features in your shell which implies you’ll be able to mix Resty with different highly effective shell instruments, reminiscent of Perl, awk, grep, sed, and so forth.

Httpie is one other command-line software that you should utilize to check your REST APIs. It is nothing however an HTTP shopper with an intuitive UI, JSON help, syntax highlighting, wget-like downloads, plugins, which makes testing REST APIs simpler and enjoyable.

HTTPie consists of a single http command designed for painless debugging and interplay with HTTP servers, RESTful APIs, and net companies, the built-in JSON help makes sending JSON requests like in POST and PUT command simpler whereas testing REST APIs.

That is all about among the greatest instruments to check your REST APIs and RESTful Net companies.  As a Java developer, I like to recommend you to put in writing your check in code utilizing RESTAssured however in order for you interactive testing, curl is your greatest buddy, significantly in case you are in Linux. In case you are a Home windows-based GUI lover developer then Postman is your greatest buddy.
