[hdorgeval]

Context:

• GOOD Playwright Version: [0.10.0]
• BAD Playwright Version: [0.11.0]
• Operating System: [Linux]
• Extra: [Travis]

Code Snippet

// this a Jest test
test('should close webkit - playwright issue v0.11.0', async (): Promise<void> => {
    // Given
    const browser = await webkit.launch({ headless: false });
    const browserContext = await browser.newContext({ viewport: null });
    const page = await browserContext.newPage();
    await page.goto('https://google.com');

    // When
    await sleep(1000);
    const previousConnectedStatus = browser.isConnected();
    await browser.close();
    await sleep(1000);
    const afterCloseConnectedStatus = browser.isConnected();

    // Then
    expect(browser).toBeDefined();
    expect(previousConnectedStatus).toBe(true);
    expect(afterCloseConnectedStatus).toBe(false);
  });

Describe the bug

Error message, for all tests that launch a webkit browser, is:

Thanks! New webkit requires libvpx5 to be installed in the environment; we've updated our .travis.yml
