+# In order to test the CleanupProjectsWithMissingNamespace migration, we need
+#  to first create an orphaned project (one with an invalid namespace_id)
+#  and then run the migration to check that the project was properly cleaned up
+#
+# The problem is that the CleanupProjectsWithMissingNamespace migration comes
+#  after the FK has been added with a previous migration (AddProjectsForeignKeyToNamespaces)
+# That means that while testing the current class we can not insert projects with an
+#  invalid namespace_id as the existing FK is correctly blocking us from doing so
+#
+# The approach that solves that problem is to:
+# - Set the schema of this test to the one prior to AddProjectsForeignKeyToNamespaces
+# - We could hardcode it to `20200508091106` (which currently is the previous
+#   migration before adding the FK) but that would mean that this test depends
+#   on migration 20200508091106 not being reverted or deleted
+# - So, we use SchemaVersionFinder that finds the previous migration and returns
+#   its schema, which we then use in the describe
+#
+# That means that we lock the schema version to the one returned by
+#  SchemaVersionFinder.previous_migration and only test the cleanup migration
+#  *without* the migration that adds the Foreign Key ever running
+# That's acceptable as the cleanup script should not be affected in any way
