     4 /* Test inclusion of previous build ID in telemetry pings when build ID changes.

     5  * bug 841028

     6  *

     7  * Cases to cover:

     8  * 1) Run with no "previousBuildID" stored in prefs:

     9  *     -> no previousBuildID in telemetry system info, new value set in prefs.

    10  * 2) previousBuildID in prefs, equal to current build ID:

    11  *     -> no previousBuildID in telemetry, prefs not updated.

    12  * 3) previousBuildID in prefs, not equal to current build ID:

    13  *     -> previousBuildID in telemetry, new value set in prefs.
