Existing browser context must be closed before creating a new one k6 0.46

Grafana k6 k6-browser

Hi @qaengineer,

Sorry for my late reply. I was out of the office.

The problem is the test script creates concurrent browser contexts, which is not allowed:

export async function firstTest() {
  const page = browser.newPage();
  // ...
}

export async function secondTest(context) {
  const page = context.newPage();
  // ...
}

See the migration guide and documentation for more details:

  1. Migrating to k6 v0.46
  2. newPage([options])
  3. context()

So, the solution is to close the browser context when a test finishes:

export async function firstTest() {
  const page = browser.newPage();

  try {
    // ... same
  } finally {
    page.close();
    browser.context().close(); // <--
  }
}

export async function secondTest() {
  const page = browser.newPage();

  try {
    // ... same
  } finally {
    page.close();
    browser.context().close(); // <--
  }
}

browser.newPage creates a new page in a new context. That’s why we should close the other context before calling newPage. The first test will create a new page in a new context and then close the context when it’s done. Then the second test will run and do the same.

Hope this helps.
