שלום @Marine
נראה שהבעיה נעוצה בהגדרות שגויות בבלוק needs.settings בקוד שלנו:
acceptance("Some tests", function (needs) {
needs.settings({
// This won't enable the right settings, so the calendar plugin won't be loaded, and the files we need won't be available
// discourse_post_event_enabled: true,
//
// Enabling the calendar will solve the issue:
calendar_enabled: true
our_plugin_enabled: true
});
test("The test", async function (assert) {
await visit("/");
assert.equal(1, 1);
});
});
