            <title>[SERVER-50972] Make tenant migration donor startup recovery more likely to cover all the 4 possible states</title>
                <link>https://jira.mongodb.org/browse/SERVER-50972</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The existing non-deterministic test theoretically should cover all the possible states, but it&apos;s tending to mostly cover the node shutting down after the migration has already committed.&lt;/p&gt;

&lt;p&gt;This ticket is to either:&lt;/p&gt;

&lt;p&gt;1) Make the test &lt;b&gt;randomly&lt;/b&gt; set one of three failpoints before starting the migration thread:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;A failpoint to make the migration hang in the dataSync state. This failpoint doesn&apos;t exist yet and could be added &lt;a href=&quot;https://github.com/mongodb/mongo/blob/cc248c4286d45eee06e2d66cdd52cd7cbae5b593/src/mongo/db/repl/tenant_migration_donor_service.cpp#L113&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;.&lt;/li&gt;
	&lt;li&gt;A failpoint to make the migration hang in the blocking state (already &lt;a href=&quot;https://github.com/mongodb/mongo/blob/cc248c4286d45eee06e2d66cdd52cd7cbae5b593/src/mongo/db/repl/tenant_migration_donor_service.cpp#L332&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;exists&lt;/a&gt;)&lt;/li&gt;
	&lt;li&gt;A failpoint to make the migration abort (already &lt;a href=&quot;https://github.com/mongodb/mongo/blob/cc248c4286d45eee06e2d66cdd52cd7cbae5b593/src/mongo/db/repl/tenant_migration_donor_service.cpp#L334&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;exists&lt;/a&gt;)&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;or&lt;/p&gt;

&lt;p&gt;2) Split the test into 4 cases, one for each failpoint (to cover kDataSync, kBlocking, and kAborted) plus one without any failpoints (to cover kCommitted).&lt;/p&gt;</description>
