Question

我正在使用mocha-grunt能够在命令行上运行/查看我的客户端测试。出于某种原因，当我在命令行上运行测试时，似乎会调用decrementColumn两次。

我想知道是否有某种phantomJS窗口范围问题与beforeEach有关，因为如果我将该代码块（新的Level实例化）复制到decrementColumn测试的顶部，那么一切都适用于浏览器和命令行。

功能

decrementColumn: function( columnPosition ){
    --this.columns[ 0 ]
},

TEST

describe( 'Level', function(){
    beforeEach( function(){
        level = new Level( [ 2, 3, 5 ] )
    })
describe( '#decrementColumn()', function(){
    it( 'should reduce column by one', function(){
        level.decrementColumn( 1 )
        expect ( level.columns[ 0 ] ).to.equal( 1 )
    })
})

}）

GRUNTFILE

module.exports = function( grunt ){
    grunt.initConfig({
        pkg: grunt.file.readJSON( 'package.json' ),
        mocha: {
            all: {
                src: [ 'test/runner.html' ],
            },
            options: {
                reporter: 'Spec',
                run: true
            }
        }
    });

    grunt.loadNpmTasks( 'grunt-mocha' )

    grunt.registerTask( 'default', [ 'mocha' ] )
};

您的测试运行器文件是什么样的？你可能错过了一条线......

<script>
    // Only tests run in real browser, injected script run if options.run == true
    if (navigator.userAgent.indexOf('PhantomJS') < 0) {
      mocha.run();
    }
</script>

Mocha在浏览器中传递测试，在命令行上失败
