Testers consider API testing to be one of the most challenging aspects of software and QA testing. APIs can be tricky as often I focus the tests on protocols and specifications that we rarely find in other testing forms.
Communication between various aspects of the program, application or the website can affect overall communication efficiency, i.e., the interface must also be checked, tested, and confirmed. Hence, global businesses have adopted API testing.
Since API is essential, it is evenly tough for applications where CI is routinely tracked, but it is crucial to go through tests.
What is an Interface or Interface Testing?
The interface is essentially a program that consists of a series of commands, messages, and other attributes that allow communication between both the device and the user. We refer to the relation that combines two components as the interface.
This interface in the computer world could be things like APIs, online services, etc. Checking these linking services or interfaces is referred to as Interface Testing.
Interface Testing gets characterized as software testing that verifies whether communication between two separate software systems is carried out correctly, as intended.
To Do Interface Tests..
Interface testing involves testing two significant segments; a web server and an application server interface, second is an application server and a database server interface.
In these cases, the interface checking gets performed to ensure if the servers are operating correctly or not. It is often performed so that errors get treated correctly. It also maintains track of the effects when the link to a web server is reset.
Types of Tests for Interface Checking
API testing mostly gets discussed in brief, but there are broad and varying API tests. There are several ways to verify API performance and protection, from functional testing to non-functional testing. It’s a topic that carries an explanation. So, let’s go through it.
We measure the functionality of each operation (in the function). The testing of every unit provides a clear vision and role of every part of the interface.
Functional testing is about checking the features of larger scenarios involving the development, validation, regression, etc. (of test cases). It usually helps in testing the efficiency of the interface.
Load testing consists of the validation of load output using practical test cases. The testing of the load output tells about the ability of the interface to cope with the load.
It checks the authentication framework, which involves penetration checking and confirmation of access protection, encryption, etc. Security testing is indeed an essential part of the interface testing procedure.
Runtime Error Detection
Runtime error detecting means tracking an application for problems like runtime, resource leakage, etc.
This type of testing ensures that the interface engine handles the workflow well enough and controls the workflow as intended. It helps in determining the manageable workflow on the interface.
Individual systems carry these tests out to check each system’s independence, such as the payment system and the inventory control system, which should function individually.
Interface testing or API testing is complicated and not straightforward enough for anyone except a professional to do it manually, so we should plan a suitable strategy to execute this test.
Often it is advised to take feedback from the production team as they understand the code better. The simplest & fastest way to run these tests is to simplify and merge the test suite into the CI so that a great deal of time gets saved and results get faster.
