karma-jasmine

问题 When I run the command grunt I get the following warning: Running "karma:unit" (karma) task Warning: No provider for "framework:jasmine"! (Resolving: framework:jasmine) Use --force to continue.

问题 In my angular2 app I have js file "connection.conf.js" with var: var appTypeConf = "example-app"; Component uses the variable from "connection.conf.js": declare var appTypeConf: string; export class Component { public appType = appTypeConf; } it works corectly in my app, but when I test application with karma, I receive a error: ReferenceError: Can't find variable: appTypeConf (line 9) How to corectly declare a variable in the component spec file? 回答1: I found the solution, I had to add

问题 un-comment the last spec.

问题 So, I've been looking all over for this, found "similar" answers here, but not exactly what I want. Right now if I want to test a single file with karma, I need to do fit() , fdescribe() on the file in question... However, what I do want is to be able to just call karma, with the config file, and direct it to a specific file, so I don't need to modify the file at all, ie: karma run --conf karma.conf.js --file /path/to/specific/test_file.js is it possible to do this?

问题 I've created Angular 5 project and writing unit tests using Karma, Jasmine.
