Trusted by Global Enterprises
The Platform

One platform. Every layer of Dynamics 365.

Horizon brings business users, QA teams, and technical teams together on a single enterprise validation platform. From APIs and data to user interfaces and AI agents, every layer is validated with confidence.

ENVIRONMENT INTELLIGENCE

Understand your Dynamics 365 environment instantly.

Horizon automatically discovers entities, customizations, ISVs, integrations, and business processes to build a complete picture of your environment before the first test executes.

  • Business processes and user workflows
  • Entities, metadata, and relationships
  • Custom fields and records
  • Validation coverage across every release
Instant test creation

Generate tests the way your business works.

Create production-ready tests with AI-powered intent-based authoring directly from real Dynamics 365 workflows. Business users define the process. Horizon handles the automation.

  • Create tests around real business workflows
  • Capture expected outcomes in business language
  • Reduce dependence on manual scripting
Headless Validation

Validate what users never see.

Query live Dynamics 365 APIs and OData services to validate data, business logic, and integrations before the UI is involved.

  • Query live production data
  • Validate values, ranges, and business rules
  • Pass variables seamlessly across workflows
End-to-end Workflow validation

Validate complete business processes.

Connect APIs, integrations, AI agents, and user workflows into a single deterministic validation that reflects how your business actually operates.

  • Connect UI, API, and integration steps
  • Validate across multiple systems
  • Share one source of truth across teams
  • Deploy every Microsoft update with confidence
ONE AUTHORING MODEL

One platform. Every team.

Business users define the process. Technical teams validate the implementation. Horizon brings both together in a single enterprise validation platform, so everyone works from the same source of truth.

✔ Business teams validate real business workflows

✔ QA teams expand regression coverage

✔ Technical teams validate APIs, data, and integrations

✔ One platform. One audit trail. One release process.

AI powered authoring

AI where it helps. Deterministic where it matters.

AI powers Instant Test Creation by capturing intent and generating production-ready tests in minutes. Every validation executes deterministically, with no AI in production runs, no per-execution AI fees, and predictable, repeatable results.

✔ AI-powered intent-based authoring

✔ Smart assertions generated automatically

✔ Deterministic execution every run

✔ No token costs or per-execution AI fees

Dynamics teams cut testing effort by up to 98%.

"It used to take seven people over two weeks to validate an upgrade. Now, one person can complete the update testing in just a few days."

“Automated testing is its one work cycle, and the tests must be maintained to remain effective. If you don’t have a dedicated testing team, you will want someone to help you maintain and update those tests. We are essentially outsourcing our testing to TheTestMart with their automated testing tool and Customer Care team. They maintain the tests for Reily Foods and ensure that everything keeps working for every update of Dynamics 365.”
IT Business Analyst, Reily Foods

Built specifically for Dynamics 365. Not adapted to it.

Approach
Where teams encounter friction
Manual testing
Slow to scale. Limited coverage. Results vary by tester and release.
RSAT
Built primarily for Finance & Operations. Task Recorder based. Support ends May 15, 2027.
Selenium / Playwright
Excellent developer frameworks, but require engineering resources and Dynamics-specific implementation.
Enterprise test platforms
Broad application coverage, but not purpose-built around Dynamics forms, metadata, APIs, and business processes.
Generic low-code testing
Easier to author, but lacks Dynamics-specific understanding of forms, OData, metadata, and business workflows.
Horizon
Built exclusively for Dynamics 365 with Instant Test Creation, Headless Validation, deterministic execution, and end-to-end workflow coverage.
