The Enterprise Validation Platform for Microsoft Dynamics 365.

Generate production-ready tests with AI-powered intent-based authoring. Validate APIs, integrations, and end-to-end business processes with deterministic execution built for every Microsoft release.

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 your Dynamics 365 entities, customizations, ISVs, integrations, and business processes. Its five-layer self-healing engine then adapts validations as forms, fields, and metadata change, preserving coverage through every Microsoft release.

Business processes and user workflows

  • Business processes, entities, metadata, and relationships
  • Customizations, ISVs, and connected integrations
  • Five-layer self-healing through Dynamics 365 updates
  • Every adjustment logged for audit and review
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 platform

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 workflows defined in plain language
  • APIs, data, and integrations validated together
  • One audit trail across every release

AI powered authoring

AI where it helps. Deterministic where it matters.

AI captures intent and generates production-ready tests. Every validation executes deterministically for predictable, repeatable, and auditable results.

  • Intent-based test creation
  • Assertions generated automatically
  • No AI decisions during execution
  • No token 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.”

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.
