/**
 * apply_ops_errors.js
 *
 * This file tests the output of the applyOps command when an exception occurs.
 * This test checks two scenarios, one where the only command fails, and one where
 * the second of three commands fails.
 * The expected outcome is that applyOps terminates and returns the error code,
 * the error message, and a list of booleans specifying which operations succeeded
 * and which ones failed. In the first case the one operation's result returns
 * false in the results array. In the second case the first operation should return
 * true, the second should return false, and the third should not be run.
 * This is all in accordance with SERVER-10771.
