无法在 PHPUnit 中使用数据提供者运行单个测试 [英] Cannot run single test with data provider in PHPUnit

问题描述

I've got a problem when using command line to run tests: if I run phpunit like this:

phpunit -–no-configuration -–filter testAdd DataTest DataProviderTest.php

it works fine. But we use a regular expression to specify exactly the name of the method that we want to be tested:

phpunit -–no-configuration -–filter /::testAdd$/ DataTest DataProviderTest.php

The second approach is not working unfortunately. Source code is:

<?php
class DataTest extends PHPUnit_Framework_TestCase
{
    /**
     * @dataProvider provider
     */
    public function testAdd($a, $b, $c)
    {
        $this->assertEquals($c, $a + $b);
    }

    public function provider()
    {
        return array(
          array(0, 0, 0),
          array(0, 1, 1),
          array(1, 0, 1),
          array(1, 1, 3)
        );
    }
}

?>

解决方案

The regex to handle tests with or without data sets is

phpunit --filter "/::<method>( with data set .*)?$/" <class> <file>

For example

phpunit --filter "/::testAdd( with data set .*)?$/" DataTest DataProviderTest.php

Since a test method won't have a space in the name unless it has a data set, you could really shrink this to

phpunit --filter "/::testAdd( .*)?$/" DataTest DataProviderTest.php
