Ατομικές δοκιμές (Unit tests)

Η σουίτα λογισμικού του Bluechain SSI συνοδεύεται από μια πλειάδα unit tests για να επιτυγχάνεται η διαρκής ορθότητα του κώδικα. Σκοπός των unit tests είναι οι βασικές λειτουργίες του συστήματος να συνεχίζουν να λειτουργούν ορθά και με τον ίδιο τρόπο, καθ'όσο αυτό αναπτύσσεται και επεκτείνεται πέραν της έκδοσης 0.3.0 (όπου βρισκόμαστε τώρα).
Συμπεριλαμβάνουμε 4 unit tests (μορφής it()) σε μορφή Javascript Promise. Καθένα από αυτά, έχει φτιαχτεί για να ελέγχει ενδελεχώς μία εκ των 4 βασικών λειτουργιών του Bluechain (βλέπε επόμενη ενότητα - 📕 Αναλυτική λίστα μεθόδων & μεταβλητών (Reference))
Στις τελευταίες εκδόσεις της Truffle, πλέον προτείνεται η δομή async/await έναντι των Promises. Είναι στα σύντομα μελλοντικά μας πλάνα να μεταπηδήσουμε τα unit tests σε αυτή τη μορφή, μιας και προσφέρουν περισσότερο έλεγχο επί της αλληλουχίας και της σειριακότητας των συναλλαγών στο σύστημα.

Εκτέλεση της σουίτας δοκιμών (test suite)

Τρέξτε όλα τα παρόντα tests πολύ απλά, με την εντολή:
$ truffle test
Για ευκολία, προσφέρουμε άλλη μια εντολή για testing με maximum logging verbosity. Χρησιμοποιήστε την σε καταστάσεις που απαιτείται ενδελεχής έλεγχος του συστήματος: $ truffle test_everything
Και αναμένουμε ως output τα αποτελέσματα των validity & performance tests:
$ truffle test_everything
