Scrittura di test unitari
Scrivere test utilizzando il framework di test unitario di MATLAB® per verificare che gli output degli script, delle funzioni o delle classi di MATLAB siano quelli previsti. Ad esempio, si può verificare che i valori di output effettivi corrispondano a quelli previsti, oppure che gli output abbiano le dimensioni previste e siano del tipo previsto.
Il framework di test unitario consente di scrivere test utilizzando script, funzioni o classi:
I test basati su script forniscono le funzionalità di base per la creazione dei test. È possibile eseguire qualifiche di base utilizzando la funzione
assertnegli script dei test.I test basati sulle funzioni seguono la filosofia dei test xUnit e forniscono ampie funzionalità per la creazione dei test. Ad esempio, è possibile utilizzare funzionalità di qualificazione avanzate, tra cui vincoli, tolleranze e diagnostica dei test.
I test basati sulle classi consentono di accedere a tutte le funzionalità del framework. Ad esempio, è possibile utilizzare impianti di test condivisi, parametrizzare i test e riutilizzare i contenuti dei test.
