/******************************************************************************
|
||
|
|
Child process that installs node-cleanup for testing zero, one, or multiple (two) concurrent cleanup handlers. It accepts a single argument of serialized JSON having the following (FlowType) structure:
|
||
|
|
|
||
|
|
{
|
||
|
|
handlers; number; // 0, 1, or 2 concurrent cleanup handlers
|
||
|
|
messages0: object|null; // messages argument for no-cleanup call, if any
|
||
|
|
messages1: object|null; // messages argument for 1st nodeCleanup() call
|
||
|
|
messages2: object|null; // messages argument for 2nd nodeCleanup() call
|
||
|
|
return1: boolean; // return value of 1st cleanup handler
|
||
|
|
return2: boolean; // return value of 2nd cleanup handler
|
||
|
|
uninstall: boolean; // whether to uninstall handlers before test
|
||
|
|
maxDuration: number; // max duration of process in millisecs
|
||
|
|
}
|
||
|
|
|
||
|
|
The process writes behavioral results to stdout for comparison with expectations. The output includes space-delimited strings from the following list, ordered in the string by their order of occurrence:
|
||
|
|
|
||
|
|
cleanup1 - the first cleanup handler ran
|
||
|
|
cleanup2 - the second cleanup handler ran
|
||
|
|
|
||
|
|
The process also writes to stderr for comparison with expectations.
