REST Assured API testing With sample requests and tests for by Chaya Thilakumara Chaya Thilakumara

On our project we are using jMeter for some REST API backend tests. But when the number of jMeter scripts had reached into the hundreds we started to face those possible issues listed above. Below are the various response code, one might encounter while API Testing. As you can see above, our response body is inside an array and we need to access the value of the ‘title’ key, hence we are using $ title. Resusablity of code, as same step defintion can be used across various scenarios.

RobotFramework is an automation framework which is actually a wrapper for selenium 2 library. It is a Keyword driven development automation framework implemented in Python. You could write Python or Java functions and import them into the project and use them as keywords.

The two ways used for testing Rest APIs are Manual Testing and Automation Testing. The most commonly used method is Automation testing for REST APIs as it helps interpret results effectively. It eliminates the aspect of writing complex codes that are required to set up an HTTP connection, send or receive a request, and parse a response. It supports100+ data sourcesand loads the data onto the desired Data Warehouse, enriches the data, and transforms it into an analysis-ready form without writing a single line of code. Data is exchanged in API Testing through XML and JSON, where XML and JSON are known to have Structured/Semi-Structured data. As XML and JSON can accept any programming language, automating the tests becomes easy.

Once those tests do what you expect them to, you can then schedule them. Tests can be ‘chained’ together for scenarios that require authentication. For example, you can have a test that make an OAuth request to Twitter, and creates a shared token that can then be used by any other test. Tests can also have validation criteria attached to ensure http status codes, or even detailed inspection of the responses using javascript or schema validation. Once tests are scheduled, you can then have alerts notify you as soon as a particular test fails validation, or is behaving out of established ranges for response time or response size.

Maven Java Project Structure:

Using this style to create basic tests of a few core pieces of functionality is a powerful way to validate your live service. Doing so may require some careful attention to setup and teardown to ensure that the tests run in a way that they do not directly affect customer data. Although JMeter api testing best practices was purposely created for load testing, it is a fantastic tool for functional API testing. It comes with a plethora of API testing functionalities and extra features to make the process more efficient. The general tendency of developers is to develop features and write test code later.

Choosing jMeter as the principal automation framework is a good choice if you have a small project. In the case you work on a big project, with a lot of endpoints, a lot of testing environments and also a CI tool to run the scripts, all of these could cause some issues. SOAPSonar is an API testing and diagnostics platform for SOAP, XML, REST-based web services. Use external sources like Excel, MS SQL, Oracle or any ODBC Database for automated tests.

# Make all requests in the context of a logged in session. REST has become quite a popular style for building APIs nowadays, it has become equally important to automate REST API test cases along with UI test cases. It covers all possible test cases for the fund transfer module and can be easily modified to accommodate more. Also, it more like writing documentation for the fund transfer module. The free tier of Runscope supports up to 10K requests per month. Frisby is easy to get started with and powerful enough to test even advanced API flows.

The test API that we are using has 10 users in its database, and with this request we pulled the information for all of them. In the output section of the test log we have the information for all ten users, but we displayed an example of two out of those ten. Robot Framework is hosted on GitHub where you can find further documentation, source code, and issue tracker. Also you can find an excellent introduction to Robot Framework API testing from my colleague Stefan by clicking here and visiting his blog post. So, let’s begin with the process of rest API testing using Robot Framework. You have probably heard about Postman, Robot Framework SoapUI, JMeter, Rest-Assured and several others that you have read about in the top 10 lists when you Google “JSON API testing tools”.

REST Assured Java Library – API Testing

If you are using api testing toolkit which is not on this list, let us know – we aim to maintain this list up to date. Chakram – JavaScript / Nodejs based end to end api testing framework. Hippie – JavaScript / Nodejs based library which adds layer of functionality and assertions for creating http api tests. Image SourceAPI Testing involves assessing the Functionality, Performance, Security, and reliability of sophisticated applications.

• The login method functions exactly as it does with Django’s regular Client class.
• JUnit is very powerful, but it has pros and cons on using it as a principal automation framework.It has HTTP requests embedded in it’s framework.
• # Make all requests in the context of a logged in session.
• For example, setting .token directly will have no effect, and setting .user directly will only work if session authentication is being used.
• Beside these simple requests we can also perform PUT, PATCH and DELETE requests, which you can find how to execute on the Robot Framework API testing GitHub site for the RESTinstance library.
• API testing is done before GUI testing, due to which fixing minute errors while enhancing the core functionalities is effortless.
• Hence the above demo represents the completion of design using CRUD pattern, wherein we can modularize and separate the data layer, API calls, test codes.

Advanced features, along with simplicity in implementation, make it a must for any testers to ensure quality in the end product. Image SourceAs seen in the above code, the status code is 200 which means it has passed the test. Similarly, other HTTP methods can be used to perform API testing using the RestAssured Framework.

Deploying a Dash App on Heroku; My First Time Experience

Go is a statically typed open-source programming language created by Google engineers with the sole purpose of simplifying complex software development processes and architectures. https://globalcloudteam.com/ Its key features include high-performance networking, concurrency and ease of use. A Goroutine is a function that runs alongside other goroutines in a program.

HTTP methods and these methods can be mapped to CRUD operations. After creating your maven project add dependencies in pom.xml. You can contribute any number of in-depth posts on all things data. Launch the app Advanced REST client , once it is installed successfully.

Java Connect to Microsoft SQL Server: 4 Easy Steps

Owing to the hundreds of testing software in the market, we have taken our time to compile a list of the best API testing tools in the market. I would like to write an automated testing suite for a REST API. As we complete new services, we’d like to check to make sure all the previously created services are working as expected. Any suggestions on the best tools to use to accomplish this? I know tools like Apigee exist that allow you to test 1 service at a time, but we’d like for a way to test all services with the click of a button.

API testing is done before GUI testing, due to which fixing minute errors while enhancing the core functionalities is effortless. If you are starting an automation project and you are new in this type of testing this is the easiest framework to use. GET– The GET method is used to extract information from the given server using a given URI. While using GET request, it should only extract data and should have no other effect on the data. Status Should Be 200 $ – Status Should be is coming from RequestsLibrary.

SOAtest efficiently transforms your API testing artifacts into security and performance tests, increasing reusability and reducing redundancy. Parasoft’s API testing platform is widely recognized as best-in-class, with innovative tooling and broad support for over 120 message formats and protocols. JMeter is used for functional API testing which includes needed to test an API. It is one of the best api testing tools which has features which help to boost the performance of API testing.

Rest Console

The main advantage of Gin is that it allows developers to create scalable and efficient applications without having to write a lot of boilerplate code. It includes built-in routing, middleware for handling functionality, a logger, and a web server. Ping-API is API testing allows to write test script in JavaScript and CoffeeScript to test your APIs. It is one of the best api testing tools which allows inspecting HTTP API call with a complete request and response data.

In our case the length of the user name is 16 characters, thus the response reported an error because the minimum length required for the name parameter is 20 characters. We can also make JSON schemas that will validate our requests and expand even further and make JSON schemas that will validate invalid requests and responses . As we can see we get the response with status 201 which means that our test was successful and all of the information we requested are posted to the server under the user with an ID of 11. When we open RIDE and we create a new test suite we just have to import the RESTinstance library in the settings section. The RequestsClient class is useful if you want to write tests that solely interact with the service interface.

Another pro for jMeter is the “modularization.” You could create jMeter test fragments and reuse them in other suites using “Include module” controller. Using this style of creating your test framework you could parameterize every test case and you could run which test case you want, not all the tests at a time. So there were a couple of challenges to integrate each of them with our custom solution. But these challenges are the beauty of building and implementing a new software architecture. • Validating status code to check whether the service is working or not, before every test run, using BACKGROUND in BDD feature file. An API or Application programming interface is a collection of software functions and procedures through which other software applications can be accessed or executed.

REST API Test Tool

If your main programming language is Java, then RestAssured is the best automation framework for REST APIs. It is an architectural style and an approach for communication used in the development of Web Services. It enables users to connect and interact with cloud services efficiently. The karate API testing tool allows re-use of payload-data and user-defined functions across tests.

Open Source Partner Resources

The most widely popular tool for API testing in the world, SoapUI allows you to test REST and SOAP APIs with ease – as it has been built specifically for API testing. Supports all types of REST, SOAP requests, SSL client certificate. Supports parallel execution of functional tests and job queuing.

If you’re using SessionAuthentication then you’ll need to include a CSRF token for any POST, PUT, PATCH or DELETE requests. To forcibly authenticate a request, use the force_authenticate() method. To support a wider set of request formats, or change the default format, see the configuration section.
