Should we handle API testing internally or outsource it?
Whether to handle API testing internally or outsource it depends on various factors, including your organization’s resources, expertise, and project requirements. While some companies prefer to conduct API testing internally, outsourcing it to a specialized testing provider like us offers several benefits, such as access to experienced testers, specialized tools, and efficient testing processes. Outsourcing API testing allows you to focus on your core business while ensuring thorough and reliable testing.
How do I know if my APIs are being tested effectively?
To determine if your APIs are being tested effectively, several metrics can be considered:
- Defect detection rate: This metric measures the effectiveness of the testing process in identifying defects or vulnerabilities. A higher defect detection rate indicates a more thorough testing approach.
- Test automation percentage: The percentage of automated tests in your API testing process indicates efficiency and scalability. Higher test automation percentages streamline testing efforts and ensure faster feedback on API performance.
- Mean time to repair (MTTR): MTTR measures the average time it takes to resolve issues or vulnerabilities identified during testing. A lower MTTR signifies a quicker response to fix API issues and ensure faster turnaround times.
