Why this program matters
Without mastering mocking, your automated tests depend critically on external services, generating false positives and chronic instability.
A team loses 30% of its time in CI/CD on fragile tests, or 40 000 € wasted annually for 5 developers, not counting delivery delays.
70% of production incidents stem from poorly mocked tests, exposing the company to revenue losses and regulatory sanctions.
Your career stalls as projects derail, while competitors deploy reliably and fast.
