Your reputation ships with every Microsoft update.

Horizon is the enterprise validation platform built exclusively for Microsoft Dynamics 365. Instant Test Creation, deterministic execution, and autonomous maintenance help enterprises deploy every Microsoft update with confidence.

Built Exclusively for Microsoft Dynamics 365
Why TestMart

The rules of ERP quality have changed.

Quarterly Dynamics 365 releases and AI-driven business processes demand a new approach.

Traditional, script-based testing was never designed for this pace of change.

Horizon delivers Instant Test Creation, autonomous maintenance, and deterministic validation so enterprises can deploy every Microsoft update with confidence.

01
Microsoft sets the cadence.

One Version. Two major waves a year. Quarterly minor releases. Continuous Lifecycle Update Policy. Manual testing cannot keep up, and generic automation approaches no longer produce verified results.

02  
AI agents are changing ERP.

Copilot Studio agents run inside Sales, Service, Finance, Supply Chain, and Commerce. They take actions on enterprise data. They need validation. So do the workflows that surround them. Every new AI-powered workflow increases the need for deterministic validation.

03
Testing entered the AI era

Gartner's first AI-Augmented Software Testing Magic Quadrant arrived October 2025. Forrester's Autonomous Testing Platforms Wave followed in Q4. The frameworks are established. Buyer questions are sharper. Vague "AI-powered" claims do not survive procurement review anymore.

Horizon was built for the future of enterprise software.

THE FIVE REASONS

Built for Dynamics 365. Not adapted to it.

Designed for enterprise ERP. Engineered for continuous change.

Complete Dynamics 365 Coverage

Purpose-built for Finance & Operations, Business Central, Sales, Customer Service, Commerce, Field Service, Power Platform, and connected ISVs. Every architectural decision starts with Dynamics 365.

No per-execution AI fees

AI powers intent-based authoring. Test execution remains deterministic with no token costs, no per-execution fees, and predictable enterprise licensing.

Instant Test Creation

Generate production-ready tests in minutes with AI-powered intent-based authoring. Eliminate manual scripting and expand coverage from the first day of onboarding.

Modernize beyond RSAT

Import existing Task Recorder assets, preserve your investment, and expand coverage with Instant Test Creation. Most customers begin migrating in days, not weeks.

Trusted by Global Enterprises

Trusted by manufacturers, retailers, distributors, financial services organizations, professional services firms, and highly regulated enterprises worldwide.

PLATFORM INTELLIGENCE

Two testing modes. One platform. Built for Dynamics 365.

Visual Intent Engine

Record by walking through the application. AI vision captures intent during authoring. Tests are created instantly. Execution is deterministic. Works on Dynamics, custom apps, third-party SaaS, and Power Apps.

Headless Validation

Validate Dynamics 365 APIs and OData services directly to verify integrations, business logic, and data integrity without a browser. Zero infrastructure. Zero extensions.

Environment Scan

Automatically discover entities, customizations, ISVs, and business processes so Horizon understands your Dynamics 365 environment before the first test runs.Three discovery layers and progressive enrichment mean the platform learns your specific environment.

End-to-End Workflows

Combine headless API validation with UI automation to test complete workflows across Dynamics 365 and connected applications with deterministic execution.

NEW  ·  AGENT VALIDATION

Your Copilot agents need validation too.

Microsoft 365 Copilot and Copilot Studio agents are becoming part of everyday work across Dynamics 365 Sales, Customer Service, Finance, Supply Chain, and Commerce.

They take actions, make decisions, and influence critical business processes. Those actions require the same level of validation as every other enterprise workflow.

Horizon validates Copilot agents with deterministic execution and a complete audit trail using the same enterprise validation platform that protects your Dynamics 365 environment. Validate agent inputs, outputs, decisions, and end-to-end business processes with confidence.

“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
