Use the FilePath class (base/files/file_path.h) to append directories with the
right separator rather than an ifdef.

+#if defined(OS_WIN)
+  file_dir = "accessibility\\event";
+#endif
+  base::FilePath test_path(dir_test_data.AppendASCII(file_dir));

It might be easiest to rewrite the code to append "accessibility" and then
append "event"

-  RunTest(event_file, "accessibility/event");
+  RunTest(event_file, file_dir);
 }
