![]() ![]() The test automation suite can be developed in any language. Language-Independent: The data transfer between the test platform to the applications is done utilizing XML or JSON and is completely independent of the languages used in developing the systems.It also results in effective cost savings for the project. It also requires less code for testing the functionalities thereby making it easier to set up and get faster access to test coverage. Time and Cost Effectiveness: This is usually less time-consuming when compared to GUI testing.The functionalities of the application would be evaluated end-to-end without the need for GUI (Graphical User Interface) which helps in detecting issues that can prove to be bigger at the time of GUI testing. Core Functionality Testing: This kind of testing provides access to the entire system without the need for a user interface.Some of the most significant advantages are as follows: There are various advantages of API testing. The developers who work on developing unit test cases have access to the source code as they need to ensure the modules developed are passed before delivery.Ĩ. In this testing, the testers do not have access to the internal source code and it focuses only on the functionality of the API. This belongs to the category of black box testing.įull system functionality is considered in API testing as the API would be used by external developers.Īs the name indicates, this testing verifies whether the unit of code works as expected or not in isolation. This testing is owned by the developers working on the corresponding modules. This testing is owned by the Quality Analyst team. What are the differences between API Testing and Unit Testing? API testing Apart from this, there are different tools like JMeter, Parasoft SOAtest, SoapUI, Apigee, API fortress, JUnit, etc. This tool helps to create manual and automated test cases for testing the APIs in a well-designed manner. The most popularly used tool in the market is PostMan. What are the most commonly used tools for API testing? What protocols can be tested using API Testing?ĪPI testing can be used for testing the following protocols:Ħ. Interoperability and WS compliance Testingĥ.There are various types of API testing, they are: What are the different types of API testing? APIs provide an abstraction to the internal business logic as they are not exposed to the world.Įxamples of APIs: Amazon API, Google Map API, Twitter API, etc.Ĥ. The general workflow of API is that it takes a request, processes it which might involve data validation, database interaction, data processing, and then the resultant of this is sent back to the source. They are nothing but a collection of functions that are executable by other functions of the software application. It facilitates data exchange between systems located in different remote places. What is API?ĪPI stands for Application Programming Interface that is useful for communication between different software systems. It deals with checking if the APIs developed work as expected in terms of reliability, functionality, security, and performance of the business logic covered by the applications. What is API testing ?ĪPI testing is a category of software integration testing that deals with the testing of Application Programming Interfaces (APIs) directly.
