Application Programming Interfaces (APIs) are the next frontier of software development, the pillar on which modern architecture of cloud services and mobile rest, enabling exchange of data between two systems. Their performance, functionality, and security are as critical and need to be tested as comprehensively.
Indium Software assesses and validates the quality of API by verifying the code and finding defects using its unique, process-oriented approach to testing gained from almost two decades of experience. Our experience in API testing includes working with:
Complex enterprises application
Configuring the database and server as per the applications requirements
Validating the quality of API for errors
Automated API testing for faster and more accurate tests using custom developed iSAFE framework.
Indium Software's Approach for API Testing
iSAFE is a customizable framework, which can be integrated with both commercial and open source tools. It helps in automating the API testing process to eliminate the chance of human errors where possible and covers the following.
Poorly designed APIs can be vulnerable to malicious attacks. Therefore, Indium Software’s Security testing includes:
– Testing the security of APIs carrying sensitive data
– Checking the authentication and data encryption over HTTP for any security threats
– Adding security scans to the existing functional tests to help achieve the task.
Check the performance and scalability of the APIs through rigorous testing.
Create and execute REST APIs, and automate the process to reduce the complexity.
– Measure the SOAP or REST web service covered by client’s Mock Services, Mock Clients and Functional tests.
– Test the functions and source lines during unit test runs.
Indium Software overcomes the challenges faced during test coverage in API such as API call sequencing, schema updates, request data combination and parameter combination.
Test the robustness of the system under non-standard circumstances such as stressful environments and exceptional conditions, simulating all possible scenarios in which a system could crash. Determine the robustness of server-side and client-side. Make repeated API calls and measure the response times.
