feat: Assert no console messages at given level(s)

[biinari]

Add assertNoConsoleMessages(array|string $levels)

Check page for console messages at specified levels:

'debug': console.debug() calls (not checked by default)
'error': console.error() calls
'info': console.info() calls
'warning': console.warn() calls (can also specify level as 'warn')

Usage:

// assert no console messages have been made at any level
$page->assertNoConsoleMessages(['debug', 'error', 'info', 'warning']);

// assert no console.warn() calls have been made
$page->assertNoConsoleMessages('warning');

// get list of console.warn() and console.error() calls made on page
$page->consoleMessages(['error', 'warning']);

Note: I have not added this assertion to assertNoSmoke() as it may not be desired by every project.
