如何解决运行测试时找不到功能的代码覆盖问题? [英] How to fix issue of code coverage not finding functions when run tests do?
问题描述
运行我的测试时，它们全部通过.当运行代码覆盖4时，由于功能未定义而失败.定义了它们(测试通过时清楚地显示了它们).我无法获得在那些测试中测试了这4个功能的文件的代码覆盖率，这不好，因为我需要知道这些功能是否经过了全面测试.
When running my tests they all pass. When running code coverage 4 fail due to functions being 'not defined'. They are defined (as the tests clearly show when they pass). I cannot get the code coverage for the file that has the 4 functions being tested in those tests which is not good as I need to know if the functions are fully tested.
我在PHPStorm上.用于这些测试的jsTestDriver有一个由我制作的文件，即Sinon v7.3.2，jQuery v1.11.1和D3.js v5.9.7作为依赖项.
I am on PHPStorm. The jsTestDriver for these tests has a file made by me, Sinon v7.3.2, jQuery v1.11.1, and D3.js v5.9.7 as dependencies.
load:
- buttonActions.js
- tests/dependencies/jquery.js
- tests/dependencies/sinon732.js
- tests/dependencies/d3.js
test:
- tests/Functional/javascriptTests/actionsTestButtonActionsFunctions.test.js
timeout: 30
buttonActions.js中的部分代码:
Partial code from buttonActions.js:
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");
}
}
我的测试中的部分代码:
Partial code from my tests:
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();
};
错误消息我正在运行代码覆盖范围:

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.
I just want to get code coverage for this file. It works for all my other file tests. Just not this one.
推荐答案
JSTestDriver中的代码覆盖范围不喜欢let和const.它不会在包含它的任何文件上运行代码覆盖范围，并且不允许包含它的文件中的功能.
Code coverage in JSTestDriver does not like let and const. It will not run code coverage on any files that contain it and will not allow functions from a file that contains it.
对于我的特殊情况，我有一个使用const的函数.我正在测试的函数中没有调用使用它的函数，因此从未进行过测试.这意味着测试通过了.但是，在同一个文件中足以使代码覆盖范围中断.
For my particular case I had a function that used const. The function that used it was not called in the functions I was testing and thus was never tested at all. This meant the tests passed. However, being in the same file was enough to make code coverage break.
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，这对我的代码或行为没有明显的影响.
My solution? Change both let and const to var. Semantically it may not be the best idea but in my case it made no noticeable difference to my code or the behaviour.
