我正在尝试获得有关Istanbul和Isparta的单元测试的信息,但遇到了一些麻烦。

实际上,这是我的gulp文件任务:

gulp.task('pre-test', ['default'], function() {
  return gulp.src('src/app/**/*.js')
    .pipe(plumber())
    .pipe(istanbul({
      instrumenter: isparta.Instrumenter,
      includeUntested: true
    }))
    .pipe(istanbul.hookRequire());
});

gulp.task('test', ['pre-test'], function() {
  return gulp.src('src/test/**/*.js')
    .pipe(mocha({reporter: 'spec'}))
    .pipe(istanbul.writeReports({}));
});


当我启动“测试”任务时,出现以下错误:

[08:34:17] Plumber found unhandled error:

如何防止这些错误发生?

最佳答案

您设置了.babelrc吗?

如果您使用的是最新版本的isparta(取决于babel v6),则需要像下面这样设置.babelrc。 (您还需要执行npm install --save-dev babel-preset-es2015

{
  "presets": [
    "es2015"
  ]
}
