Overview

This example demonstrates the “Exec Log Streaming” test suite. Specifically, it shows how to should stream exec logs every second for 20 seconds. Review the source code below to understand the implementation details and patterns used.

​
Live Test Run

A live test recording will be available after the next CI run.

Source Code

exec-stream-logs.test.mjs
import { describe, expect, it } from "vitest";
import { TestDriver } from "testdriverai/vitest/hooks";

describe("Exec Log Streaming", () => {
  it("should stream exec logs every second for 20 seconds", async (context) => {
    const testdriver = TestDriver(context, { ip: context.ip || process.env.TD_IP, headless: true });
    await testdriver.provision.chrome({ url: "about:blank" });

    const code = `for i in $(seq 1 20); do echo "log line $i at $(date +%T)"; sleep 1; done`;

    const result = await testdriver.exec({
      language: "sh",
      code,
      timeout: 30000,
    });

    console.log("exec result:", result);

    // Verify we got all 20 log lines
    for (let i = 1; i <= 20; i++) {
      expect(result).toContain(`log line ${i}`);
    }
  });
});
