API Testing
About API Testing
A software application is
made of three essential parts:
1.Database Layer: Where all the data is
retrieved or stored in a database/file system.
2.Logic Layer: All the logic is stored in this
layer. This caters to processing the data between the front end
and the back-end. All this logic is written in form of
Application Programming Interface (APIs).
3.User Interface Layer: This is the front end
of the application through which the users interact and all
their actions are converted into instructions that are
understandable to the software or vice versa.
Api
Testing focuses on business logic layer of the software
architecture.
Why Is API Testing Important?
Continuous testing is very
important to make sure that the incremental software product
works as per the requirements and nothing gets broken. In many
of the organizations, the user interface is formed quite late
for testing through the user interface and hence product
testing comes quite late during the SDLC. The risk of putting a
bad, and potentially insecure, product on the market is greater
than the cost to test it.
Hence
API testing is one of the best mechanism for the quick
turnaround and providing the feedback to the developers on
their code. A bad product released to the end users is
catastrophic. API testing is one of the most challenging parts
of the chain of software because QA team has to create an
interface or framework to test both individual functionalities
and a series or chain of functionalities, discovering how they
work together from end to end. It is essential to test the APIs
to make sure that:
Save Functional Testing Time
Integrate GUI Tests Easily
Access to Application without User Interface
Check Overall Build Strength
Agiloworks API Testing methodology
Included the following steps :-
1. API Specification Review
2. Test Case Development
3. Test Framework Development
4. Test Script Development
5. Test Execution and Reporting
Why Us?
With strong development background, our team is highly capable to build complex frameworks for catering to the customer’s needs very quickly
We build our own scripts and frameworks in addition to using industry known tools and frameowrks like SoapUI, Postman, PACT etc
We are quite capable in setting up the test environments for doing API Testing , considering it many times becomes a complex task due to no GUI availability and customer’s needs from both provider and consumer’s point of view
Our engineers understand the functionality of the API program and clearly define the scope of the program
Various testing techniques such as equivalence classes, boundary value analysis and error guessing are applied based on which the test cases are written for the API
Based on our expertise, we are able to unearth various issues around error handling, unused flags, duplicate functionalities, multi threading issues, API performance , unstructured response output etc. This has helped our customers to get a quick feedback at the earlier phase of the development cycle
Performance and Load Testing
Performance testing is a
form of software testing that focuses on how a system behaves
under a particular load. In today’s scenario, the client
server applications are working in varying loads ranging from
hundreds of thousands of simultaneous users and hence are
expected to work successfully. Therefore, performance and load
testing are very important aspects of testing done for any
such application in order to predict the load it can sustain.
Performance testing should
give developers the diagnostic information they need to
eliminate bottlenecks.
AgiloWorks has a dedicated
team which is expert in in developing the performance tests for
applications. We have a strong expertise around licensed tools
like Load Runner and open source like J-Meter and others . Our
team with a strong development background has also customized
the tests with different modules and scripts that provide lot of
customized reports helpful for the customers.
