## Demo Test Run

Watch this test execute in a real sandbox environment:

{/* assert.test.mjs output */}
<iframe 
  src="https://api-test.testdriver.ai/api/v1/testdriver/testcase/69c5d038058ffe89003c6adc/replay"

## Source Code

```javascript title="assert.test.mjs" {22-24}
/**
 * TestDriver SDK - Assert Test (Vitest)
 * Converted from: testdriver/acceptance/assert.yaml
 */

import { describe, expect, it } from "vitest";
import { TestDriver } from "testdriverai/vitest/hooks";

describe("Assert Test", () => {
  it("should assert the testdriver login page shows", async (context) => {
    const testdriver = TestDriver(context, { ip: context.ip || process.env.TD_IP,
    });
    
    // provision.chrome() automatically calls ready() and starts dashcam
    await testdriver.provision.chrome({
      url: 'http://testdriver-sandbox.vercel.app/login',
    });

    // Take a screenshot
    await testdriver.screenshot();

    // Assert the TestDriver.ai Sandbox login page is displayed
    const result = await testdriver.assert(
      "the TestDriver.ai Sandbox login page is displayed",
    );

    expect(result).toBeTruthy();
  });
  // it("should assert the testdriver login page shows 2", async (context) => {
  //   const testdriver = TestDriver(context);
    
  //   // provision.chrome() automatically calls ready() and starts dashcam
  //   await testdriver.provision.chrome({
  //     url: 'http://testdriver-sandbox.vercel.app/login',
  //   });

  //   // Assert the TestDriver.ai Sandbox login page is displayed
  //   const result = await testdriver.assert(
  //     "the TestDriver.ai Sandbox login page is displayed",
  //   );

  //   expect(result).toBeTruthy();
  // });
});
```
