TestMesh is a modern TypeScript testing library with support for dependency graphs, visualization, and parallel execution.

Features

• Dependency Graph - Tests can depend on each other
• Visualization - Real-time web interface for monitoring execution
• Parallel Execution - Automatic optimization of execution order
• Convenient DSL - Intuitive API for creating tests
• TypeScript - Full type safety out of the box
• CLI - Convenient command-line interface

Quick Start

Installation

Creating Tests

import { TestMesh, mesh, expect } from "testmesh";

const suite = mesh()
  .suite("My tests")
  .test("basic test")
  .run(async () => {
    expect(2 + 2).toBe(4);
  })
  .test("test with dependency")
  .dependsOn("basic test")
  .run(async () => {
    expect("hello").toBe("hello");
  })
  .build();

const testMesh = new TestMesh({
  parallel: true,
  visualization: { autoOpen: true },
});

testMesh.addSuite(suite);
await testMesh.run();

Running via CLI

# Create a template
npx testmesh init

# Run tests
npx testmesh run -f tests.ts

# Run only the visualizer
npx testmesh visualize
