SaaS testing challenges addressed by DeviQA

DeviQA turns SaaS workflows, tenant permissions, subscription rules, and workload expectations into tests that help teams validate releases, protect customer data, and assess scalability.

Faster development creates testing backlogs

Challenge

55% of respondents in DeviQA’s 2026 survey reported growing QA queues as AI-assisted development accelerated delivery.

Solution

We automate regression checks for onboarding, subscriptions, billing, and core workflows, integrating prioritized suites into CI/CD to support frequent releases.

Access-control failures put customer data at risk

Challenge

Broken Access Control ranks #1 in the OWASP Top 10:2025, highlighting the importance of verifying who can access data and perform actions.

Solution

We test tenant isolation, role-based permissions, and API authorization to identify cross-account data exposure and unauthorized actions.

API changes can break connected workflows

Challenge

Only 17% of respondents in Postman’s 2025 State of the API Report reported using contract testing.

Solution

We validate API contracts and test workflows involving payment providers, identity services, and CRM integrations, including retries, duplicate events, and failed requests.

Growth puts service reliability under pressure

Challenge

Uptime Institute’s 2026 outage analysis reports that 57% of respondents to its 2025 annual survey put the cost of their most recent major outage above $100,000.

Solution

We simulate concurrent tenant activity, traffic spikes, and sustained workloads to identify capacity limits, resource contention, and recovery issues before production deployment.
