If you use Bootstrap-sass, You should describe karma.conf.js

preprocessors : {
  './src/test.ts': [ '@angular/cli' ],
  './node_modules/bootstrap-sass/assets/stylesheets/_bootstrap.scss': [ 'scss' ],
  './src/*.scss': [ 'scss' ]
},

It is important write order that bootstrap is faster than your file.
