/**
 * Test the flow run, especially with embedded flows.
 *
 * This test uses executions/embedded2. It also mainly uses the flow named jobf. The test is
 * designed to control success/failures explicitly so we don't have to time the flow exactly.
 *
 * Flow jobf looks like the following:
 *
 * <pre>
 *       joba       joba1
 *      /  |  \      |
 *     /   |   \     |
 *  jobb  jobd jobc  |
 *     \   |   /    /
 *      \  |  /    /
 *        jobe    /
 *         |     /
 *         |    /
 *        jobf
 * </pre>
 *
 * The job 'jobb' is an embedded flow:
 *
 * jobb:innerFlow
 *
 * <pre>
 *        innerJobA
 *        /       \
 *   innerJobB   innerJobC
 *        \       /
 *        innerFlow
 *
 * </pre>
 *
 * The job 'jobd' is a simple embedded flow:
 *
 * jobd:innerFlow2
 *
 * <pre>
 *       innerJobA
 *           |
 *       innerFlow2
 * </pre>
 *
 * The following tests checks each stage of the flow run by forcing jobs to succeed or fail.
