Code coverage for laravel dusk
Dusk is using Browsers to run tests and the Browser can't see the PHP code that's being executed. The only way that I see to achieve code coverage with Dusk is to create a option in php artisan serve that would be possible to count and create the coverage file.
Conceptually, you need to bootstrap all your requests w/ PHP Unit's code coverage tools.
You can do this with phpunit libraries directly, or via xdebug's coverage tools (which use phpunit).
From this sample gist that I found, you can start coverage tools based on a couple of _GET parameters passed via the Dusk test.
public function testBasicExample()
{
$this->browse(function (Browser $browser) {
$browser->visit(route('test', [
'test_name' => 'testBasicExample',
'coverage_dir' => '/app/Http'
]))->assertSee('test');
});
}
The code that does the work is two parts 1. Start collecting based on parameters:
$test_name = $_GET['test_name'];
require __DIR__ . '/../vendor/autoload.php';
$current_dir = __DIR__;
$coverage = new SebastianBergmann\CodeCoverage\CodeCoverage;
$filter = $coverage->filter();
$filter->addDirectoryToWhitelist(
$current_dir . '/..' . ((isset($_GET['coverage_dir']) && $_GET['coverage_dir'])
? $_GET['coverage_dir']
: '/app')
);
$coverage->start($test_name);
And 2 end collecting and output:
function end_coverage()
{
global $test_name;
global $coverage;
global $filter;
global $current_dir;
$coverageName = $current_dir . '/coverages/coverage-' . $test_name . '-' . microtime(true);
try {
$coverage->stop();
$writer = new \SebastianBergmann\CodeCoverage\Report\Html\Facade;
$writer->process($coverage, $current_dir . '/../public/report/' . $test_name);
$writer = new SebastianBergmann\CodeCoverage\Report\PHP();
} catch (Exception $ex) {
file_put_contents($coverageName . '.ex', $ex);
}
}
The end collection is called using a clever little trick where the class coverage_dumper
has just a destructor, which gets called automatically when php ends the process.
The code itself can use a bit of tidy up as far as output paths, and variables go, but from a concept, it should work.
