php - 如何跳过 PHPUnit 中的错误测试？

Question

当相关的数据集出现错误时，如何让 PHPUnit 跳过测试？

---

作品

如果我的数据提供者只有导致错误的东西，那么它会适本地跳过依赖测试。 注意 已跳过:1

class DataProviderDependsTest extends PHPUnit_Framework_TestCase
{
    public function getDataProvider(){
      return [
        ['non-existent_file.txt'],
      ];
    }

    /**
     *  @dataProvider getDataProvider
     */
    public function testCanBeDependedOn($data){
      $actual = file_get_contents($data);
      $this->assertSame('expected',$actual);
    }

    /**
     *  @dataProvider getDataProvider
     *  @depends testCanBeDependedOn
     */
    public function testCanDepend($data){
      $this->assertTrue(false);
    }
}

不起作用

但是，如果我向提供程序添加了一条好数据，那么尽管其余部分导致了错误，PHPUnit 仍会继续执行所有 相关测试(甚至有错误的相应数据集)。它不会跳过任何东西。 注意向数据提供者添加的['real_file.txt'],。

class DataProviderDependsTest extends PHPUnit_Framework_TestCase
{
    public function getDataProvider(){
      return [
        ['real_file.txt'],
        ['non-existent_file.txt'],
      ];
    }

    /**
     *  @dataProvider getDataProvider
     */
    public function testCanBeDependedOn($data){
      $actual = file_get_contents($data);
      $this->assertSame('expected',$actual);
    }

    /**
     *  @dataProvider getDataProvider
     *  @depends testCanBeDependedOn
     */
    public function testCanDepend($data){
      $this->assertTrue(false);
    }
}

PHPUnit 不会跳过 @depends使用 @dataProvider 时的错误测试

来自 their docs :

Note

When a test depends on a test that uses data providers, the depending test will be executed when the test it depends upon is successful for at least one data set.

如果依赖测试中提供的数据的任何部分导致错误，我想一起跳过一些测试。有什么方法可以解决此限制？

您可以 fork these files如果需要，可以进行快速测试，或者只是克隆:

git clone https://github.com/admonkey/phpunittest.git

也许这是您期望的行为:

<?php

class DataProviderDependsTest extends PHPUnit_Framework_TestCase
{
    protected static $failed = false;

    public function getDataProvider() {
        return [
            ['real_file.txt'],
            ['non-existent_file.txt'],
        ];
    }

    /**
     * @dataProvider getDataProvider
     */
    public function testCanBeDependedOn($data) {
        try {
            $actual = file_get_contents($data);
            self::assertSame('expected', $actual);
        } catch(Exception $e) {
            self::$failed = true;
            throw $e;
        }
    }

    /**
     * @dataProvider getDataProvider
     * @depends testCanBeDependedOn
     */
    public function testCanDepend($data) {
        if (self::$failed) {
            self::markTestSkipped('testCanBeDependedOn failed');
        }
        self::assertTrue(true);
    }
}
