Après la mise à jour d'angular 7 à partir d'angular 6 avec des changements de code minimes dans notre dépôt de code, les exécutions de test de karma uni sont devenues très lentes, et lorsqu'elles sont exécutées avec le paramètre watch défini sur true, elles ne parviennent pas à recharger/relier les tests immédiatement après avoir enregistré un fichier, alors que la plupart du temps, il faut 4 minutes après l'enregistrement d'un fichier pour redéclencher l'exécution de test, ou dans certains cas, il y a un dépassement de temps. Un seul ng test L'exécution du karma avec angular 7 prend généralement environ 3 minutes, comme c'était le cas avec angular 6. La lenteur de 4 minutes dans angular 7 persiste même lors de l'exécution d'un seul fichier spec, dont l'exécution et la reconstruction ne prenaient que quelques secondes avant la mise à niveau vers angular 7.
