Different types of testing exist because software can fail in many ways—functionally, technically, or from a user’s perspective. Each testing type ensures quality from a different perspective, targeting different risks.
| Type | Description | Purpose |
|---|---|---|
| Unit Testing | Tests individual components | Catch early defects in code logic |
| Configuration Testing | Verifies SaaS configuration, feature toggles, roles, and workflows | Ensures SaaS setup supports business processes |
| Integration Testing | Tests interaction between modules and/or data flow between systems | Ensure modules work together and/or data flows accurately between systems (e.g., ERP, HR, CRM, data warehouses) |
| System Testing | End-to-end testing of the system | Verify overall functionality |
| Regression Testing | Re-test after changes | Ensure existing features are not adversely affected by new changes |
| User Acceptance Testing (UAT) | Business-focused validation | Ensure software meets user needs |
| Usability Testing | Evaluate ease of use | Improve adoption and efficiency |
| Performance Testing | Test responsiveness and stability | Confirm system can handle expected load |
| Security Testing | Identify vulnerabilities | Protect data and meet compliance standards |
