如何解决运行测试时代码覆盖率找不到函数的问题？

Question

当运行我的测试全部通过时。当运行代码覆盖率 4 由于函数 'not defined' 而失败时。它们是已定义的（正如测试在通过时清楚地显示的那样）。我无法获得在这些测试中测试了 4 个函数的文件的代码覆盖率，这不好，因为我需要知道这些函数是否经过全面测试。

我在使用 PHPStorm。这些测试的 jsTestDriver 有一个我制作的文件，Sinon v7.3.2，jQuery v1.11.1 和 D3.js v5.9.7 作为依赖项。

load:
  - buttonActions.js
  - tests/dependencies/jquery.js
  - tests/dependencies/sinon732.js
  - tests/dependencies/d3.js

test:
  - tests/Functional/javascriptTests/actionsTestButtonActionsFunctions.test.js

timeout: 30

来自 buttonActions.js 的部分代码：

function _hideOrShow(table){

    var classNames = table[0]["attributes"][0]['nodeValue'];
    var secondClass = classNames.replace("sortable table-striped table-responsive ",'');

if (secondClass === "veryHidden" ) {
    table.removeClass("veryHidden").addClass("veryShown");
} else {
    table.removeClass("veryShown").addClass("veryHidden");
}

}

我测试的部分代码：

 ActionsTestButton = TestCase("ActionsTestButtonActions");

 ActionsTestButton.prototype.setUp = function() {
//stuff done here. Not important
}

ActionsTestButton.prototype.testHideOrShow = function () {

var table = {
    class: "sortable table-striped table-responsive veryHidden",
    0: {
        attributes: {
            0: {
                nodeValue: "sortable table-striped table-responsive veryHidden"
            }
        }
    },
    removeClass: function (name){
        table.class = table.class.replace(name, '');
        table[0]["attributes"][0]['nodeValue'] = table.class;
        return {
            addClass: function (name){
                table.class = table.class+name;
                table[0]["attributes"][0]['nodeValue'] = table.class;
            }
        }
    }

 };

assertEquals("sortable table-striped table-responsive veryHidden", table.class);
assertEquals("sortable table-striped table-responsive veryHidden", table[0]["attributes"][0]['nodeValue']);

_hideOrShow(table);

assertEquals("sortable table-striped table-responsive veryShown", table.class);
assertEquals("sortable table-striped table-responsive veryShown", table[0]["attributes"][0]['nodeValue']);

_hideOrShow(table);

 assertEquals("sortable table-striped table-responsive veryHidden", table.class);
 assertEquals("sortable table-striped table-responsive veryHidden", table[0]["attributes"][0]['nodeValue']);

 };

     ActionsTestButton.prototype.tearDown = function() {
document.getElementById.restore();
window.$.restore();
window.d3.select.restore();

 };

我收到的错误消息运行代码覆盖率：

我只想获取此文件的代码覆盖率。它适用于我所有其他文件测试。只是不是这个。

Answer 1

JSTestDriver 中的代码覆盖率不像 let 和 const。它不会运行代码覆盖任何包含它的文件，也不会允许包含它的文件中的函数。

对于我的特殊情况，我有一个使用 const 的函数。使用它的函数没有在我正在测试的函数中调用，因此根本没有被测试过。这意味着测试通过了。但是，在同一个文件中足以破坏代码覆盖率。

我的解决方案？将 let 和 const 都更改为 var。从语义上讲，这可能不是最好的主意，但就我而言，它对我的代码或行为没有明显影响。
