如何在更新时自动运行单个phpunit测试？

Question

I am using Laravel 5.3 and unfortunately when you run gulp tdd, a change to 1 file runs the entire test suite which now takes nearly 2 minutes. With reference to this post, I started using Grunt to run specific tests when specific files are changed. Sample Gruntfile below:

Gruntfile.js:

var phpunit = 'vendor/bin/phpunit ';
grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),
    watch: {
        HomeSrc: {
            files: [
                'app/Http/**/HomeController.php',
                'resources/views/home/**/*.php'
            ],
            tasks: ['HomeTests']
        },
    shell: {
        HomeTests: { command: phpunit + 'tests/Home' },
    }
});

However, now my Gruntfile is getting pretty long and I would like to run specific test files when they are changed.

Questions

1. Is there a more efficient way to do this? (better organization of the Grunfile or using Gulp instead)
2. How can I run a specific test when its file is changed?

Example: When tests/Home/IndexTest.php is changed, automatically run vendor/bin/phpunit tests/Home/IndexTest.php

OK, to handle this you will need to catch the matched file name and dynamically set a variable to use as the unit test file. This should cover all basic mappings where the test class name is exactly the same name as the file name it is within, and supports namespaces so not all test files with the same class name will be picked up by the filter.

Example:

grunt.initConfig({
    // .. snipped ..
    unitTestFile: 'to_be_replaced',
    watch: {
        php: {
            files: ["tests/**/*.php"],
            tasks: ["shell:unitTest"],
            options: {
                spawn: false
            }
        }
    },
    shell: {
        unitTest: {
            command: "phpunit --filter <%= unitTestFile %>"
        }
    }

    grunt.loadNpmTasks('grunt-shell');

    grunt.event.on('watch', function (action, filepath) {
        if (grunt.file.isMatch(grunt.config('watch.php.files'), filepath)) {
            var testFile = filepath.replace(/\\/g, '\\\\');
            grunt.config('unitTestFile', testFile.replace(/.php/, ''));
        }
    });
};

So, a file named tests\unit\ApplicationTest.php and within a namespace of tests\unit if changed will now run that as a test. The resulting command being:

phpunit --filter tests\\unit\\ApplicationTest // only runs in this namespace
