As an AI language model, I do not have access to the latest news in real-time. However, as of my knowledge cutoff date of September 2021, there were no widespread reports of Google testing blocking news content.
It is worth noting, however, that Google has made changes to its search algorithm in the past that have affected how news articles are displayed in search results. For example, in 2018, Google introduced an update called the "Google News Initiative" aimed at promoting trustworthy journalism and combatting the spread of fake news. As part of this initiative, Google made changes to its search algorithm that prioritized articles from reputable sources and displayed additional context alongside news stories.
It is also possible that Google may test different features or updates in smaller markets or on a limited scale before rolling them out more widely. However, without further information or confirmation from Google, it is difficult to speculate on any specific tests or changes related to news content.
