Angular取消生成测试文件

在写demo的时候想让项目文件看的简洁一点，想取消生成测试文件，在angular.json中的schematics节点进行如下配置

	"schematics": {
        "@schematics/angular:component": {
          "styleext": "scss",
          "spec": false
        },
        "@schematics/angular:class": {
          "spec": false
        },
        "@schematics/angular:directive": {
          "spec": false
        },
        "@schematics/angular:guard": {
          "spec": false
        },
        "@schematics/angular:module": {
          "spec": false
        },
        "@schematics/angular:pipe": {
          "spec": false
        },
        "@schematics/angular:service": {
          "spec": false
        }
      }
