API Testing

What is API testing in software testing?

Application Programming Interface (API)

is a pack of code that acts as an interface between two computers. APIs offer auditing services from external software that we can set up into our own programs. API Testing is the stage in software testing where we test the functionality, working, reliability, performance, and other condition of an API.

Why is API testing essential?

As definite above, we implement API in a program to accomplish connection between two components of a software application.

We charge API testing to accept whether the output approved from the first application or database is proper, well-structured, and useful to another application.

API testing also adjust the feedback of an API. There is a set of specific rules that check how the data should act, based on the following:

• The type of input
• The mandatory authentication parameters
• Regardless of whether delicate information is sent safely over the network
• How long an API takes to return the value

Layers in a software / application

Generally, applications have several layers. Frequently, they have these three layers:

1. Data layer
2. Service layer (API)
3. Presentation layer

The service layer where the APIs consist is also known as a business layer. API testing is involved at this phase of an application, and is the most urgent part in programming testing.

How to perform API testing

We can plan API testing on a software application manually or through online tools applicable in both free and paid versions. API testing associate some types that are helpful in certain different condition of API.

1. Functionality testing
2. Load testing
3. Reliability testing
4. Security testing
5. Validation testing, and few more

These categories differ from software to software. Large scale software’s contain in-depth testing of an API, while small-scale ones do not desire much testing.

Postman, SoapUI, RapidAPI, and Katalon Studio are a few extensively used API testing tools accessible for developers and testers.

Advantages of API testing

API testing is very useful in a software application, and it includes various advantages, such as the following:

• API testing enhances our test coverage.
• It eases our load by creating quick releases of products.
• It benefits us with clear test maintenance of work.
• Automated API testing lower testing cost as compared to manual testing of an API.
• Previous testing helps the tester to complete those errors that could appear during GUI testing.

Learning from a scratch in a short period is also very important in the learning process. Best Automation testing tools training in Kochi or any other places helps you to understand more in right way. In depth knowledge of syllabus and practical gives more confidence.
