Hello Everyone! Welcome back to another Fresh article of MODTECHSTUFF where you Learn Automation testing.In this article, we will talk about API Testing and open-source API Testing tools.
(API) Application Programming interface testing tools is more significant now than any other time in recent memory.
As we move towards progressively Agile move left programming development forms like continuous Integration, the need to rapidly give test analysis to our engineers is expanding.
One ruin to UI tests is they are moderate, settling on them a poor decision for telling developers rapidly if their code has broken the most recent form or not. Application Programming interface tests, then again, will in general be quicker and run more dependably than GUI tests.
That why I make this rundown of the best free API Testing Tools you should know.
What is API?
In simple terms, we can understand Application Programming Interfaces (API) as a medium of communication between two systems/computers/applications.
While most functional testing includes testing a UI like a site page or form, API testing includes bypassing a UI and discussing legitimately with an application by making calls to its APIs.
Application Programming interface testing permits you to test headless advances like JMS HTTP, databases, and Web administrations.
Application Programming interface testing is once in a while called "headless" testing
For Example-
API use is the "sign in utilizing Stackoverflow /Twitter/Google/Quora" usefulness you see on such a significant number of sites.
Rather than really signing in to clients' online networking accounts (which would represent a genuine security concern), applications with this usefulness influence these stages' APIs to confirm the client with each login. For instance, here's the Facebook Login API.
The manner in which it works is quite basic. Each time the application loads, it utilizes the API to check whether the client is now signed in by methods for whatever web-based social networking stage. If not, when the client taps the "Sign in Using Google/Facebook" button, a spring up opens where they are approached to affirm they really need to sign in with that web-based social networking profile. At the point when the client affirms, the API gives the application distinguishing proof data, so it knows who's signing in.
Here is the list of the top API testing tools that can be utilized for Rest and Soap Web Service Testing. Programming interface devices are extraordinary in light of the fact that multiple occasions you can use one test content to help with API load/stress performance testing, security testing.
1.Postman
Postman began with Chrome application extension however as of late came out with local adaptations for both Mac and Windows.
We can utilize it to send a post request to your web server and it gives you the reaction back. It permits you to set up all the headers and treats your API, and afterward check the response when it returns.
Postman used for both automated and exploratory testing, compatible with Mac, Windows, Linux Operating System.
2.Karate DSL
Karate permits you to make a test that can arrangement calls to any sort of web-services and attest that the reactions are true to form. Expand on Cucumber-JVM, run a test, and produce reports like any standard Java venture.
3. SoapUI
SoapUI is a headless useful testing tool from SmartBear programming. It comes in two versions: open-source form and Pro Version. Since the open-source, you can really access the full source code while the paid version gives you a lot more features.
4. HttpMaster
HttpMaster is a testing tool to automate testing of sites and applications. It very well may be utilized to test RESTful web administrations and API applications. HttpMaster additionally permits you to and screen API reactions.
HttpsMaster venture offers worldwide alternatives to modify your API demand Parameter abilities empower you to incorporate powerful information with your request.
5. Rest-Assured
Rest-Assured is an open-source Java Domain-explicit language (DSL) that makes testing REST administration basic. It improves things by taking out the need to utilize standard code to test and approve complex reactions. It additionally underpins XML and JSON Request/Responses. This is likely the most popular testing tool to test the rest API. Backing BDD Given/When/Then syntax structure
6. RestSharp
RestSharp is a straightforward REST and HTTP API Client for .NET compatible with .NET 3.5+, Silverlight 5, Windows Phone 8, Mono, MonoTouch, Mono for Android
Simple establishment utilizing NuGet for most .NET flavors GET, POST, PUT, PATCH, HEAD, OPTIONS, DELETE calls supported.
7.Rest Console
HTTP Client and Request Visualizer and testing tool enable engineers to manufacture, investigate, and test RESTful APIs. Rest Console is an HTTP Request Visualizer and Constructor instrument that enables designers to manufacture, investigate, and test RESTful APIs.
8. RoboHydra
RoboHydra is a testing device for HTTP-based customers. The thought is, rather than associating your customers under-test to the genuine server, you interface them to RoboHydra and make RoboHydra react with whatever you require for each request.
9. Hippie-swagger
Hippie-swagger is a tool for testing RESTful APIs. It's likewise an API testing apparatus with programmed strut affirmations. Notwithstanding approving API conduct, it will bomb tests when strut documentation is absent or off base.
Can approve All parts of the document approved; parameters, demand/reaction body, ways, and so on.
10. WebInject
WebInject is open-source testing tools for automated testing of web applications and services. It very well may be utilized to test singular framework parts that have HTTP interfaces like PHP, AJAX, Servlets, HTML Forms, XML/SOAP Web Services, REST, and so forth.
11. PyRestTest
PyRestTest is a python based REST testing and API small scale benchmarking API testing device
You can compose your tests in essential YAML or JSON config records, no code required.
12. Airborne
Airborne is an open-source testing tool based Ruby API testing structure.
13. Unirest
Unirest is well-known for API testing, lightweight HTTP demand customer libraries.
14. Mockbin
Mockbin testing tool permits you to create custom endpoints to test, counterfeit, and track HTTP demands and reactions between libraries, attachments, and APIs.
15. Citrus
Citrus is an open-source system that can assist you with automation reconciliation tests for all intents and purposes any informing convention or information group. It has decent test outcomes reports also.
16. ZeroCode
ZeroCode is a free and open-source, lightweight API testing device library based on JUnit center sprinters, for API endpoints, utilizing straightforward JSON steps. utilized in enormous endeavor organizations like swiss Bank.
17. Katalon studio
Essentially known as a GUI automation test tool Katalon studio additionally supports test situations that utilization web benefits and can be utilized as an API test apparatus. A few advantages of Katalon Studio are: It's not publicly released however it is free It's a finished bundle and structure. So it simple to introduce and get working.
18. JMeter
As you would definitely know JMeter was produced for load testing yet numerous tester likewise use it for API testing and as an API load testing instrument also.
A few advantages of JMeter are:
Can use one API test content for the two API and as an API Performance testing. Handily incorporated into CI/CD situations.
19. Tavern
The tavern is a pytest module, order line device, and API testing instruments Python library for automation testing of APIs.
20. Chakram
Chakram is a REST Javascript API testing tool structure that additionally has a BDD testing style and completely abusing guarantees.
Wrap-UP
I hope this article has helped to focus on why API Testing is important and with the details of open-source API testing tools.
