This should not be a member variable if you move it. Instead it should be a
local variable (original code before comment by marq was correct). Can you fix
as a followup?

Correct code should be:

  ToolsMediatorTest()
      : consumer_(OCMProtocolMock(@protocol(ToolsConsumer))),
        configuration_(
            [[ToolsMenuConfiguration alloc] initWithDisplayView:nil]) {
    auto navigation_manager = base::MakeUnique<ToolbarTestNavigationManager>();
    test_web_state_.SetNavigationManager(std::move(navigation_manager));
  }

  ToolbarTestNavigationManager* navigation_manager() {
    return static_cast<ToolbarTestNavigationManager*>(
        test_web_state_.GetNavigationManager());
  }

Then change the code to access the navigation manager via the accessor instead
of the local raw pointer (and remove the navigation_manager_ and
navigation_manager member fields).

+    navigation_manager_ = navigation_manager.get();
+    test_web_state_.SetNavigationManager(std::move(navigation_manager));
+  }
+
  protected:
   ToolsMediator* mediator_;
+  id consumer_;
+  ToolsMenuConfiguration* configuration_;
+  ToolbarTestWebState test_web_state_;
+  ToolbarTestNavigationManager* navigation_manager_;
+
+ private:
+  std::unique_ptr<ToolbarTestNavigationManager> navigation_manager;
 };
