Below are the various response code, one might encounter while API Testing. REST API Test Tool. JMeter; Advanced REST client (for google chrome- select app from a list). An API or Application Programming Interface is a set of programming instructions for accessing a web-based software.
Contents.API testing overview API testing involves testing APIs directly (in isolation) and as part of the end-to-end transactions exercised during integration testing. Beyond, these transactions include multiple types of endpoints such as,. API testing is performed on APIs that the development team produces as well as APIs that the team consumes within their application (including third-party APIs).API testing is used to determine whether APIs return the correct response (in the expected format) for a broad range of feasible requests, react properly to such as failures and unexpected/extreme inputs, deliver responses in an, and respond securely to potential. Is used in conjunction with API testing to isolate the services under test as well as expand test environment access by simulating APIs/services that are not accessible for testing.API testing commonly includes testing APIs or with or being sent over,. It can also include message formats such as, and similar fixed-length formats, and being sent oversuch as,.
API testing, GUI testing, and test automation API Testing is recognised as being more suitable for and (especially the automation used with and ) than GUI testing. Reasons cited include:. System complexity: GUI tests can't sufficiently verify functional paths and back-end APIs/services associated with multitier architectures. APIs are considered the most stable interface to the system under test.
Short release cycles with fast feedback loops: Agile and DevOps teams working with short iterations and fast feedback loops find that GUI tests require considerable rework to keep pace with frequent change. Tests at the API layer are less brittle and easier to maintain.For these reasons, it is recommended that teams increase their level of API testing while decreasing their reliance on GUI testing. API testing is recommended for the vast majority of test automation efforts and as much edge testing as possible. GUI testing is then reserved for validating typical use cases at the system level, mobile testing, and usability testing. Types of API testing API testing typically involves the following practices:. Testing the functionality of individual operations. Testing the functionality of broader scenarios, often using unit tests as building blocks for end-to-end tests.

List of the best free online API Testing Tools for Testing REST and SOAP APIs and Web Services:Application Programming Interfaces (API) testing is a type of software testing where testing cannot be done at a front-end since there’s no GUI.API testing has mainly performed the testing on message layer and includes testing REST API’s, SOAP Web services, which could be sent over HTTP, HTTPS, JMS, and MQ. This now forms an integral component for any Automation Testing.Due to the nature of API testing, it cannot be tested manually, and we need to opt for some API test tools for testing APIs. In this article, I have covered a list of some top API testing tools. Importance of API testing through a test pyramid:The ROI for the API testing will be higher when compared to the other testing types which are performed by the testers.The below figure will give you the exact information on how much we need to focus on API Testing. As API tests are in the second layer, these are important and it needs 20% of testing efforts.image While testing an API, the focus should be on using the software in such a way in which the API will be called.Hence, during testing, we need to check if the API will return the correct output under different conditions. The output which the API returns is generally the pass or fail status, data, or a call to another API. For more accuracy and in API testing, data-driven testing should be performed.In order to test the API, the testers prefer when compared to. This is because manual testing of API includes writing of a code to test it.

API testing is conducted at the message layer as there is an absence of GUI.Before you start API testing, you need to set up the test environment with a set of parameters. Configure the database and server as per the requirement. Then just like we perform smoke testing for an application, check the API by making an API call.
This step will ensure you that nothing is broken and you can continue for the thorough testing.The various levels of testing that you can perform for testing an API are Functionality Testing, Load Testing, Reliability Testing, API documentation Testing, and Proficiency Testing.Points you should consider for an API testing are as follows:. Target Audience or API consumer. The environment in which the API is going to be used. Testing aspects. Test for normal conditions. Tests for abnormal conditions or negative tests.= to suggest your listing here. It is an open source framework for API testing.
This framework is based on cucumber library. With this tool, a tester can test web services by writing tests in domain specific language.This tool is specially designed for automated API testing and is released by Intuit. To use this tool there is no need to have a programming language. But the basic understanding of HTTP, JSON, XML, XPath, and JsonPath will be an added advantage.Features:.
