With this test we POST the data related to our new album. We do that by creating a new JSONObject with the artist, title, and year of the new album. This object is then added to the body in the given section of the test.
To disable the shrinker, pass the `–no-shrink` flag to this command. With the use of the REST API the server has no status, we can restart the server between two calls, inspite of all the data is transferred to the server. REST uses different representation to define the resources like text, JSON and XML. The most popular representation of resources is JSON and XML.
POST method is used to send new information to the server, or to update already existing information, by entering the requested information in the request body before sending it. Most often, this method is used to create new entries in an existing database. Those were some basic curl HTTP calls with a few options. Now we will combine them and show examples against a production ready API. For the examples I will use the API running on localhost.
- Im my previous article we used publicly available REST endpoints for our tests.
- The 1st call is just getting all of the albums and extracts the json response to a Response object.
- It is a string of characters designed for unambiguous identification of resources and extensibility by the URI scheme.
- API testing allows the communication between two software systems.
- File which consist of the list of all APIs that are required to be activated and are activated for any particular program run.
- Development and API test automation can happen in parallel.
- All functional scenarios can be reused to perform load and stress testing.
With this strategy, the first call is used to extract valid test data so we can confirm the 2nd call is returning the correct data. Since we’re doing this with no hardcoded test data, changes to the underlying data will not cause the test to fail. The 1st call is just getting all of the albums and extracts the json response to a Response object.
Working With Rest Apis Using Serenity Screenplay
API or “Application Programming Interface” is an interface between two software systems, which provides interaction and data sharing. The basic principle of API is to send requests to a server and receive a response, indicating to the sender whether the request was successful or not. API testing is yet another way to test your project. It provides additional advantages, such as speedy test execution, or the ability to test even before the UI has been created. In this blog post we learned the basic principles of what an API is, what is it’s purpose, and how to use it to create simple requests using REST Assured, and some of the pros and cons of using it.
Both of these tests have hardcoded test data, which is typically not ideal. Easy to integrate with JUnit and TestNG frameworks, for greater added functionality. A bit more complex request is a POST request, which includes everything the GET method has, as well as a body containing input data. The level of complexity is determined by the user when creating test cases using REST Assured. Here are a few simple examples of basic calls using some of the most popular methods, starting with GET. Statement that can help me understand wether response data returned from server equals to expected data.
File which consist of the list of all APIs that are required to be activated and are activated for any particular program run. This is essential as every test run does not require all APIs. In Screenplay, tests describe behaviour in terms of actors, who achieve their business goals by performing tasks. These tasks usually involve interacting with the application in some way. And to perform these tasks, we give the actors various abilities.
All functional scenarios can be reused to perform load and stress testing. To start using Rest Assured, you will need to add REST Assured dependencies to your project, depending on if you are using Gradle or Maven with your project. Executing curl with no parameters on a URL will execute a GET.

Framework also includes code libraries, compiler and other programs used in the software development process. In this case, we use a jsonPath expression (data.first_name) that will return all of the first_name field values. The Hamcrest matcher hasItems will compare the collection of first names that the jsonPath query returns, and check that it contains the names “George”, “Janet” and “Emma”.
On the upside, we can now seamlessly integrate our REST Assured-tests in a larger TestNG-based test framework and profit from the automatic report generation that TestNG provides. Required a bean of type ‘org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder’ that could not be found. REST architecture treats any content as resource, which can be text files, HTML pages, images, videos or dynamic business information. REST server gives the functionality to access the resources and modifies them. We can identify the each resources by URIs/ global IDs. UI testing means the testing of the graphical user interface.
To do this I am going to quickly setup my own endpoints locally, using an open source tool called JSON server. API tests both manually and automated run much faster because the tester physically does not need to go through the UI, repost test data. All it takes is a single, or multiple, API calls to be performed to successfully test functionality. Photo by Markus Spiske / Unsplash REST Assured is an open source Java library that is used when building automated tests for REST endpoints.
It is enough to specify the desired data which needs to be updated. PUT method is used only to update existing data and returns a positive result only if the system contains already existing and updatable data. These response codes are designed so that the first number of each code corresponds to a certain informative group, which reflects the type of response it has. I am just scratching the surface in this blog post.

This message consists message data and Meta data i.e. information on the message itself. REST API is a set of function helps the developers performing requests when the response is receiving. Through HTTP protocol interaction is made in REST API. API framework is defined by configuration file which consists the rest api testing list of all APIs that is required to be activated and activated for a particular program run. Framework is similar to an Application Programming Interface, technically framework includes API. Framework serves foundation for programming while API provides access to the elements supported by the framework.
In API testing, we send a request to API with the known data and then analysis the response. API helps in communication and data exchange between two software systems. API act as an interface between two applications and allows the two software systems communicate with one another.
API is a part of integration testing to check whether the API meets expectations in terms of functionality, reliability, performance, and security of applications. In API testing, our primary focus is on Business Logic Layer of the software architecture. For those of you wanting to add the possibility to validate RESTful web services to your test automation framework, REST Assured can be a very useful way to do just that. In this post, I want to show you how to perform some basic tests on both JSON and XML-based REST services. The whole purpose of API testing is end to end testing of the functionality.Unit testing is done by the developer.
What Are The Advantages Of Api Testing?
As mentioned, I will be using curl to simulate HEAD, GET, POST, PUT and DELETE request calls against a REST API. Your requirements could not be resolved to an installable set of packages. Add an instance variable of type Safe to the class Room. This instance variable should be initialised in the constructor of Room, and an appropriate query should be defined to get it. The shrinker may have failed to optimize the Java bytecode.
All you need to do is invoke the service using get() and then perform the required checks using assertThat() and the equalTo() matcher . Identifying the response elements to be checked is done using a dot notation. For example, customer.id identifies the id element that is a child of the customer element, which is the root element of the response message. Installing and https://globalcloudteam.com/ configuring REST Assured is easy, just download the latest version from the website and add the relevant .jar files to your testing project and you’re good to go. It is a string of characters designed for unambiguous identification of resources and extensibility by the URI scheme. The purpose of URI is to locate the resource on the server hosting of the web service.
In addition to providing an endpoint to retrieve your data, JSON Server allows you to make POST, PUT, PATCH or DELETE requests, making it an ideal solution for mocking endpoints. Ability to combine all other command line tool executions and unit tests into test scenarios with additional assertions and data extractions between system command steps. We at TestDevLab are working with various API testing tools on a daily basis and have vast experience with them.
What Protocol Is Used By The Restful Web Services?
In a REST API, GET requests are used to query a REST resource. Let’s see how we can do this using Serenity Screenplay. You can find the complete code for this series of blog posts in my Github project. In the then section we are validating the data was successfully posted.
What Are The Differences Between Soap And Rest Api?
In unit testing every functionality is separately tested. Im my previous article we used publicly available REST endpoints for our tests. For this article I want build tests for endpoints that I create and define.
In my previous REST Assured post I covered how to get your environment setup and how to run a couple basic REST Assured tests. REST Assured is a Java language library for testing and validating REST web services, based on HTTP. This DSL or “Domain-Specific Language” went into development in 2010. Unlike other competitors, REST Assured is open source, which makes it easily accessible to everyone, therefore, becoming one of the most popular REST API validation tools. REST or “Representational State Transfer” is a type of architecture created as a guideline for computer systems.
But Screenplay is also a great fit for API or web service tests. In particular, Screenplay is ideal when we want to include API and UI activities in the same test. For example, we might have an API task to set up some test data, a UI task to illustrate how a user interacts with this data, then another API task to check the new state of the database. In addition to testing GET endpoints, we can also test POSTs and DELETEs.
We can use SOAP API to perform the operation on records like create, retrieve, update or delete. We can use API to manage password, perform searches etc. It remains in the browser history and has length restriction.
What Is Resource In Rest?
In this case, we use the Get interaction class, which comes bundled with serenity-screenplay-rest. With this article you should have a good start on using REST Assured for testing API endpoints. Of course there is a lot more to it than the basics I’ve described, so go ahead and do some more research on your own at the official REST Assured website.
You can easily mock the expected responses and once the API is implemented, your tests can point to that implementation instead of JSON Server. Development and API test automation can happen in parallel. You have reached the blog of TestDevLab – your partner in software quality assurance. Here you can get to know us better and join discussions about software testing, test automation and development. Not an open source tool, though customer support will be available for upcoming community version. Option to create test sets, based on functionality and level of severity.
