Generate Playwright Tests from Real User Sessions

You already have the real user flow. Why write the same test from scratch?

Playwright is a browser automation framework for testing web apps. https://playwright.dev/

This guide shows how to turn live behavior into tests with Gasoline Agentic Devtools.

Quick Terms

• Playwright test: Automated browser test script.
• Session: Recorded sequence of actions and browser state.
• Regression test: Test that protects against bugs returning later.

The Problem You Are Solving

You want to go from:

“Quality Assurance found a bug in this exact flow”

to:

“Now we have a repeatable test for it.”

Step-by-Step with Gasoline Agentic Devtools

Step 1. Record the real flow

configure({what: "recording_start"})
// perform the real user path
configure({what: "recording_stop", recording_id: "rec-checkout"})

Step 2. Generate a test artifact

generate({
  what: "test",
  test_name: "checkout-happy-path",
  assert_network: true,
  assert_no_errors: true,
  assert_response_shape: true
})

Step 3. Save output and run in your pipeline

generate({what: "test", output_format: "file", save_to: "./tests/checkout.spec.ts"})

Step 4. Heal broken selectors when UI changes

generate({what: "test_heal", action: "analyze", test_file: "./tests/checkout.spec.ts"})

Why This Helps New Teams

• Less manual scripting.
• More tests based on actual user behavior.
• Faster conversion of bugs into long-term protection.

You’re Building Durable Quality

When every major bug becomes a test, your product gets stronger every week. Gasoline Agentic Devtools makes that transition much easier.
