Issue Description

PowerShell extension reports global variables as assigned but not used when they are not used from within a .psm1 module file. However, global variables may be used by scripts outside that module importing it.

Expected Behaviour

Global variables should never be reported as being unused.

Actual Behaviour

PowerShell extension reports global variables as assigned but not used when they are not used from within a .psm1 module file.

Non vengono indicati file sorgente, test o punti di ingresso. Inizia individuando la logica dell’analizzatore che segnala le variabili assegnate ma non utilizzate e i test che coprono l’ambito dei moduli o delle variabili globali. Conferma il comportamento attuale, quindi aggiorna le aspettative dei test pertinenti in modo che le variabili globali non vengano segnalate come inutilizzate ed esegui i test dell’analizzatore interessati.
