            <title>[SERVER-62396] Add a non-deterministic variant for `ThreadPoolTaskExecutor` tests</title>
                <link>https://jira.mongodb.org/browse/SERVER-62396</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Add a new variant to &lt;tt&gt;ThreadPoolTaskExecutor&lt;/tt&gt; tests, similar to &lt;a href=&quot;https://github.com/mongodb/mongo/blob/8e681e80447e5859f79296e10911ffec39f31efa/src/mongo/executor/thread_pool_task_executor_test.cpp#L52-L56&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;ThreadPoolExecutorCommonTests&lt;/tt&gt;&lt;/a&gt;, that uses a non-synchronized mocked &lt;tt&gt;NetworkInterface&lt;/tt&gt; to allow races to occur in our testing environment.&lt;/p&gt;

&lt;p&gt;Existing tests use &lt;tt&gt;NetworkInterfaceMockinterface&lt;/tt&gt;, which synchronizes with the executor threads for deterministic execution of tests:&lt;/p&gt;

&lt;blockquote&gt;
&lt;p&gt;The thread acting as the &quot;network&quot; and the executor run thread are highly synchronized by this code, allowing for deterministic control of operation interleaving.&lt;/p&gt;&lt;/blockquote&gt;

&lt;p&gt;This synchronization does not allow data-races to show up in our testing environment, in particular under TSAN variants.&lt;/p&gt;</description>
