在使用Karma的角度2应用程序中设置测试时遇到一些问题。我一直在关注ng-cli和ng2-test-seed repo（https://github.com/juliemr/ng2-test-seed/）创建的类似模式。模式是像正常一样运行业力，包含文件，然后使用system.js导入并运行测试文件。一切都是最新的，karma @ current，angular @当前发布候选人（1）
我一直得到一个非常无益的错误，似乎与找不到的文件有关;起初它是我的systemjs.config.js文件，但现在是一些角度测试组件：
create or replace trigger
after insert on cars
for each row
declare
cursor c_trigger is
select p.name, c.license_plate
from people p, cars c
where p.ID=c.ID
and c.license_plate=:new.licenseplate;
v_trigger c_trigger%rowtype;
begin
open c_trigger;
dbms_output.put_line('The client' || v_trigger.name || 'has bought the car whose license plate is' || v_trigger.license_plate);
fetch c_trigger into v_trigger;
close c_trigger;
end trigger;
/
这是我的karma-test-shim.js文件，除了过滤要包含的规范文件之外，它还包括并帮助支架构建，以便它可以运行
这是我的karma.conf.js文件
