How can you best test APIs for Financial Technology?

3 Design and document test cases

Test cases are the instructions that tell you what to test, how to test, and what to expect from the APIs. You need to design and document test cases that cover all the possible scenarios and inputs that the APIs can encounter. You need to use clear and consistent naming conventions, descriptions, and formats for your test cases. You also need to use data-driven and parameterized testing techniques to reduce redundancy and increase coverage. You can use tools like Swagger, OpenAPI, or RAML to document your test cases and generate test scripts.

4 Execute and automate test cases

Once you have your test cases ready, you need to execute them and verify the results. You can use tools like Postman Runner, SoapUI TestRunner, or Rest-Assured TestNG to run your test cases manually or automatically. You can also use tools like Jenkins, Travis CI, or GitHub Actions to automate your test cases and integrate them with your continuous integration and delivery pipeline. Automating your test cases will help you save time, detect bugs early, and ensure consistency.

5 Analyze and report test results

The final step of testing APIs is to analyze and report the test results. You need to check if the APIs met the expected outcomes and performance indicators, as well as if they complied with the standards and regulations of the fintech industry. You also need to identify any errors, failures, or anomalies that occurred during the testing process. You can use tools like Postman Reports, SoapUI Reports, or Rest-Assured Reports to generate and visualize your test results. You can also use tools like Jira, Trello, or Slack to communicate and collaborate with your team and stakeholders.
