grunt-spec-check

Find and list JavaScript files that do not have corresponding specs / tests

This is a simple task to help find untested files. Code coverage tools like Istanbul are excellent for generating code coverage reports, however they generally do not alert you to files which are untested. This task will simply iterate through each file and check that there is a corresponding test case. The task can be configured to fail the build or just provide warnings, depending on how strict you want to be.

The task will not in anyway run the JavaScript files or check that the test case even does anything. It is a simple task to complement coverage tools by letting you know which files are untested.

Getting Started

This plugin requires Grunt ~0.4.5

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

1npm install grunt-spec-check --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

1grunt.loadNpmTasks('grunt-spec-check');

The "specCheck" task

Overview

In your project's Gruntfile, add a section named specCheck to the data object passed into grunt.initConfig().

1grunt.initConfig({
2  specCheck: {
3    options: {
4      // Task-specific options go here.
5    },
6    your_target: {
7      // Target-specific file lists and/or options go here.
8    },
9  },
10});

Options

options.baseDir

Type: String Default value: /lib

A string value that corresponds to the location of the scripts that should be tested. When searching for a spec this section of the filepath is replaced with the value specified for testDir

options.testDir

Type: String Default value: /test

A string value that corresponds to the location of your test files. It is assumed that the directory structure of your test files matches that of your tested files.

options.severity

Type: String Default value: 'fatal'

A string value that determines the severity of the failure. Valid options are 'fatal' (fails build) and 'warn'

options.convention

Type: String Default value: 'Spec.js'

A string value that corresponds to the convention for naming your test files. The default is the Jasmine convention where 'file.js' is tested by 'fileSpec.js'

The task works by replacing '.js' with the value provided here. So:

• '.spec.js' : file.js => file.spec.js
• 'Test.js' : file.js' => 'fileTest.js

Usage Examples

Default Options

In this example, we check for corresponding test cases for all JavaScript files, and throw a fatal warning if any test cases are missing.

1grunt.initConfig({
2  specCheck: {
3    files: {
4      src: ["lib/**/*.js"]
5    },
6  },
7});

Custom Options

In this example, we check for corresponding test cases for all JavaScript files, but we exclude any debug files. Our test naming convention is to use the term Test instead of Spec, and we only want to list untested files and not fail the build. We are also using template properties to cut down on repeated file paths.

1grunt.initConfig({
2  app: {
3    'tests': 'src/test/resources/scripts',
4    'scripts': 'src/main/resources/scripts'
5  },
6  specCheck: {
7    options: {
8      convention: "Test.js"
9      severity: "warn",
10      testDir: "<%= app.scripts %>",
11      baseDir: "<%= app.tests %>"
12    }
13    files: {
14      src: [
15        "<%= app.scripts %>/**/*.js",
16        "!<%= app.scripts %>/**/*debug.js",
17      ]
18    },
19  },
20});
