What's on the platform
Jump to any area—import specs, generate tests, run them, and track results.
Import API to Project
Bring your API definitions into the platform in one step—projects, features, and endpoints are created automatically.
In practice: upload a file or paste a URL; the platform parses your spec and builds the structure so you can start testing immediately.
- Choose REST API with OpenAPI/Swagger specification.
- Import from URL or upload a file (.json, .yaml, .yml).
- Projects, features, and endpoints are created automatically so you can start generating tests right away.
Accepted formats
OpenAPI 3.0, Swagger 2.0 — .json, .yaml, .yml or URL
AI-powered test generation and coverage
Reach 100% functional and production-grade coverage with one-click generation and gap-fill suggestions.
The AI analyzes your OpenAPI/Swagger schemas and suggests tests for happy paths, edge cases, and missing parameters.
- Generate initial tests for any endpoint to get coverage started.
- Overall coverage = status codes, parameters, request body.
- Production-grade coverage = schema, headers, auth, routing, performance, data integrity, error body.
- See a clear coverage verdict and use Generate tests for gaps to reach 100%.
Run tests your way
Execute API tests on the server for CI/CD and scheduled runs, or run them locally for development and private APIs.
Same test packs run in both modes—choose backend for pipelines or local runner for private APIs.
- Backend execution—trigger test packs via REST API from GitHub Actions, GitLab CI, Jenkins, Azure DevOps.
- Local runner—run the same tests on your machine for fast feedback and private endpoints.
Two ways to run
Backend execution
Best for CI/CD and scheduled runs. Always available.
Local runner
Best for development and private APIs. Start when you need it.
How AI-Powered No-Code API Testing Works
Total Shift Left turns your OpenAPI, Swagger, and Postman collections into executable API regression and contract tests—enabling shift-left API testing in your CI/CD pipeline.
How it works
One platform for API testing and automation.
Chain APIs into workflows
Run end-to-end integration scenarios with full visibility. Define multi-step API flows and validate behavior across services.
- Define workflow steps
- Execute and monitor runs
- Full visibility and reporting
Endpoint and test management
Organize projects, features, and endpoints with full test visibility and coverage at a glance.
Navigate by project → features → endpoints; view test cases and coverage % per endpoint.
- Navigate by project → features → endpoints with search.
- View test cases and coverage % per endpoint.
- Add tests manually or use Generate tests for AI-generated suites.
API mocks for development and testing
Create static or dynamic mock responses so frontend and backend teams can work in parallel without live backends.
Run mocks as a standalone server or use them automatically during test execution with condition-based responses.
- Static and dynamic responses—fixed JSON or templates with variables.
- Run mocks as a standalone server for external testing.
- Test integration—mocks are used automatically during test execution.
- Condition-based responses and endpoint linking.
Analytics and reporting
Track total tests, success rate, response time, and coverage so you can ship with confidence.
See average response time, 95th percentile, throughput, and test case creation over time.
- Total tests, success rate, failed tests, and coverage %.
- Average response time, 95th percentile, and throughput.
- Test case creation over time and most active users.

What API formats can I import?
Total Shift Left supports OpenAPI 3.0 and Swagger 2.0 specifications in JSON, YAML, or .yml format. You can import from a URL or by uploading a file. Once imported, the platform discovers all endpoints and organizes them into projects and features.How does AI test generation work?
The platform analyzes your OpenAPI/Swagger specs and endpoint schemas to suggest test cases. You can generate initial tests for an endpoint or use "Generate tests for gaps" to add tests that cover missing parameters, status codes, or request-body scenarios. Coverage is tracked as overall (functional) and production-grade (schema, headers, auth, routing, performance, data integrity, error body).How do I run tests in CI/CD?
Use Backend Execution for CI/CD and scheduled runs—it is always available. The platform exposes a REST API (Swagger-documented) to trigger test packs, check status, and retrieve results so you can integrate with GitHub Actions, GitLab CI, Jenkins, Azure DevOps, and other pipelines.What are API mocks used for?
API mocks let you create static or dynamic mock responses for your endpoints. You can run mocks as a standalone server for external testing or use them automatically during test execution. Mocks are linked to your existing endpoints and support condition-based responses.How is coverage calculated?
Overall coverage reflects functional coverage: status codes, parameters, and request body. Production-grade coverage adds schema/contract validation, HTTP semantics, routing and methods, data integrity, auth depth, performance/SLA, and error body validation. The platform shows a coverage verdict and identifies gaps so you can generate tests to reach 100%.
