Next to this PR #2712 I wanted to add test assertion on dispatchBrowserEvent and not only on emited event.
I reuse same logic as the ComponentWithEmit.php.

$this->assertComponentDispatchEvent($testComponent->render(), 'browserEvent')
    ->withPayload(['amount' => 2, 'unit' => 'kg'])
    ->withPayloadSubset(['amount' => 2]) ;

$this->assertComponentNotDispatchEvent($testComponent->render(), 'otherBrowserEvent');

I'm asking myself if it's better to create a dedicated component that only have one action that dispatch browser event rather than reuse ComponentWithEmit.php
