The system test fails to install joomla on my Windows machine. The test fails to find the next button on the page with the language select.

I see that in the test we have this

 // Select a random language to force reloading of the lang strings after selecting English
$I->selectOptionInChosen('#jform_language', 'Danish (DK)');
$I->selectOptionInChosen('#jform_language', 'English (United Kingdom)');

In my case I end up with danish, instead of english. Tried with waiting 2 sec between the selection, but this didn't help either. The only way to go around this is to just select english.

I'm also not sure that I understand the logic of the comment? Force reloading of the lang strings? The default language is english? Why do we need to reload it?
