未获取代码覆盖率信息答案

【问题描述】：

我正在对我们现有的 Webapp 文件夹结构进行单元测试实验。当我在 AMD 和非 AMD js 文件上运行测试时，单元测试会运行，但我没有得到每个测试的代码覆盖率。我假设这是因为目录结构（见下文）；将“node_modules”和“intern_tests”下移一级（“internjs”）。如果我将“node_modules”和“intern_tests”文件夹移动到 Webapp 文件夹下，这一切都有效（运行 + 覆盖）。我正在运行 2.1.1 版。代码覆盖率是否适用于这种类型的目录结构？

文件夹结构：

WebApp (top)
   |- example_apps (example AMD and non-AMD apps)

   |- internjs ( run tests from here )
        |- node_modules

        |- intern_tests
               |- unit (test js apps under example_apps)

非 AMD 单元测试：

define([
    'intern!object',
    'intern/chai!assert',
    // made a package under intern.js
    'intern/order!exampleApps/calc.js'
], function (registerSuite, assert) {
    registerSuite({ ....

AMD 单元测试：

define([
    'intern!object',
    'intern/chai!assert',
    'intern/chai!config',
    'exampleApps/hello'
], function (registerSuite, assert, config, hello) {
    registerSuite({ ...

intern_unit.js：

loader: {
    // Packages that should be registered with the loader in each testing environment
    packages: [ { name: 'exampleApps', location: '../example_apps' } ]
},

// Non-functional test suite(s) to run in each browser
suites: [
    'intern_tests/unit/unit_hello',
    'intern_tests/unit/unit_calc2'

],

输出：

./node_modules/.bin/intern-client config=intern_tests/intern_unit
PASS: main - hello - greet (1ms)
0/1 tests failed
PASS: main - test_calc - sum (0ms)
0/1 tests failed
0/2 tests failed

注意，它运行但没有代码覆盖 'example_apps' 目录下一级的两个 js 文件。

【解决方案1】：

我想通了。我必须从 WebApp（顶部）运行脚本。下面是新配置。

命令行：

user:~/WebApp$ ./intenjs/node_modules/.bin/intern-client config=internjs/intern_tests/intern_unit

intern_unit.js

loader: {
    // Packages that should be registered with the loader in each testing environment
    packages: [ { name: 'exampleApps', location: 'example_apps' },
                { name: 'internTests', location: 'internjs/intern_tests' } ]
},

// Non-functional test suite(s) to run in each browser
suites: [
    // AMD
    'internTests/unit/unit_hello',
    // non-AMD
    'internjs/intern_tests/unit/unit_calc2'

],

// A regular expression matching URLs to files that should not be included in code coverage analysis
excludeInstrumentation: /^(?:internjs)\//

非 AMD 测试脚本：

define([
    'intern!object',
    'intern/chai!assert',
    // non-AMD, saw this in tutorial
    'intern/order!../../../example_apps/calc.js'
    // this also works
//    '../../../example_apps/calc.js'
], function (registerSuite, assert) {

AMD 测试脚本：

define([
    'intern!object',
    'intern/chai!assert',
    'intern/chai!config',
    'exampleApps/hello'
], function (registerSuite, assert, config, hello) {
