Fintech API Testing: From 40 Tests to 600 in Six Weeks with BotGauge

Background

A fintech startup runs dozens of microservices handling transfers, KYC, and ledger updates.

Challenge

• Only 40 API tests covered a rapidly growing surface
• Edge cases such as failed transfers and duplicate requests went untested
• Every missed bug carried financial and compliance risk

Solution

Using BotGauge, the team generated and maintained API test suites that covered happy paths, error responses, and boundary values. Tests ran automatically in the CI pipeline on every pull request.

Results

• Test coverage grew from 40 to 600+ tests in six weeks
• Critical API defects were caught before merge
• Audit preparation time dropped by roughly half

Key Takeaway

In fintech, coverage is a safety net. BotGauge helped the team scale coverage without growing headcount.
