API Testing Services | API Testing Company

API testing can be one of the most challenging parts of software and QA testing because APIs can be complicated, they are often based on protocols and standards that we often do no encounter in other kinds of testing. While developers tend to test only the basic functionality they are working on, testers are in charge of testing functionality, performance and security of APIs, discovering how all components work together from end to end.

APIs are what gives value to an application. It’s what makes our phones “smart”, and it’s what streamlines business processes. If an API doesn’t work efficiently and effectively, it will never be adopted, regardless if it is a free or not. Also, if an API breaks because errors weren’t detected, there is the threat of not only breaking a single application, but an entire chain of business processes hinged to it

Our API Testing Services

Load Testing

We ensure that an API can handle large amount of calls.

Reliability Testing

Ensure that API can be consistently connected to and lead to consistent results.

Functionality Testing

Ensure that the API works and does exactly what it’s supposed to do.

Security Testing

The API has defined security requirements including authentication, permissions and access controls. See some API security tips for protecting vital data.

Negative Testing

This is for checking every kind of wrong input the user can possibly supply.

API Documentation Testing

Also called discovery testing, the API documentation easily guides the user.

Types of API’s we Test

REST

REST stands for REpresentational State Transfer which is new on the block as compared to SOAP which means it must overcome all the problems with SOAP. REST is a lightweight protocol which uses URL for all the needed information. It uses four HTTP methods to perform task-

Get- To get the information. For example getting longitude and latitude in case of location mapping API.
Post- To insert some data in resource.
Put- To update the resource.
Delete- To delete from resource.

SOAP

SOAP API- Stands for Simple Object Access Protocol. It uses XML for message exchanging. All the information which is required to perform this task is given in its WSDL which is Web Service Description Language. SOAP is heavy weight due to its extensive used standards and XML. The main advantages of SOAP over Rest is that it has built in error handling and it can be used with other protocols like SMTP

Our Approach for API Testing

Test for the typical or expected results first

Add stress to the system through a series of API load tests

Test for failure. Make sure you understand how your API will fail. Just make sure the API fails consistently and gracefully

Group test cases by test category

Prioritize API function calls so that it will be easy for testers to test quickly and easily

Limit the tests from as many variables as possible by keeping it as isolated as possible

See how it handles unforeseen problems and loads by throwing as much as you can at it

Perform well-planned call sequencing

For complete test coverage, create test cases for all possible API input combinations

Automate wherever we can
