Gitlab CI 和 PHPUnit Lumen - 即使测试通过，CI 也会失败答案

【问题标题】：Gitlab CI and PHPUnit Lumen - CI fails even though tests passGitlab CI 和 PHPUnit Lumen - 即使测试通过，CI 也会失败
【发布时间】：2017-04-15 06:40:18
【问题描述】：

由于某种原因，我在 PHP Lumen 应用程序上运行 PHPUnit 测试的 Gitlab CI 作业刚刚开始失败——尽管测试实际上都通过了。

这是我的 YAML 文件：

    image: php:7.1.3

cache:
  paths:
  - vendor/

before_script:
- apt-get -qq update -y
- apt-get -qq install openssh-client -y
- apt-get -qq install git -y
- apt-get -qq install zip unzip
# setup the private key
- eval $(ssh-agent -s)
- ssh-add <(echo "$SSH_PRIVATE_KEY")
- mkdir -p ~/.ssh
- echo -e "Host *\n\tStrictHostKeyChecking no\n\n" > ~/.ssh/config
- ssh -L 3306:127.0.0.1:3306 XXX@xxx.xxx.xxx.xxx -Nf
- curl -sS https://getcomposer.org/installer | php
- php composer.phar install

stages:
  - test


phpunit:
  stage: test
  script:
  - vendor/bin/phpunit --configuration phpunit.xml || exit 1

这是构建日志：

就像我说的那样，这些测试实际上已经通过了，而且几天前还没有通过 CI。

谁能给点建议？

Gitlab 版本：GitLab 社区版 8.17.0 77254ab 使用 Docker 的 CI runner（迄今为止的最新版本）

【问题讨论】：

标签： php phpunit gitlab lumen gitlab-ci

【解决方案1】：

您是否查看过标有XX 的文件？似乎它们不包含任何测试或不遵守 phpunit 的约定，即测试必须以 test 为前缀。如果您的测试文件夹中有不包含测试的文件，您可能需要修复它们或将其丢弃。

我创建了一个示例来演示该问题：

<?php

require_once __DIR__ . '/vendor/autoload.php';

use PHPUnit\Framework\TestCase;

class Question43423064Test extends TestCase
{
    //function testTrue() { $this->assertTrue(true); }
}

运行该测试时，我会得到与您类似的输出：

dbr:stackoverflow/ $ phpunit Question43423064Test.php 
PHPUnit 6.0.6 by Sebastian Bergmann and contributors.

W                                                                   1 / 1 (100%)

Time: 64 ms, Memory: 8.00MB

There was 1 warning:

1) Warning
No tests found in class "Question43423064Test".

WARNINGS!
Tests: 1, Assertions: 0, Warnings: 1.

dbr:stackoverflow/ $ echo $?
1

echo $? 将打印最后一个返回码，如您所见，它是 1。如果您删除注释或添加跳过的注释，警告将消失，退出码应返回 0。

tl;dr 看起来您要么必须丢弃这些文件，要么修复包含的测试，或者如果您想稍后修复它们，可能会将它们标记为已跳过。

【讨论】：

警告是否会导致 phpunit 返回不等于零的值？大多数测试工具只会在出现错误时返回非零错误代码。
是的，至少在我的机器上是这样。您可以在 CLI 中运行 phpunit 后尝试echo $?，它将返回最后返回的状态代码，即 1。从您提供的输出来看，它在 CI 环境中返回相同的状态代码。
好的，那么您可能是对的，警告导致了问题。作业失败是因为测试失败了。
PhpUnit 在没有测试时也会返回成功。在这种情况下，它会警告没有指定测试的测试文件。由于这可能是一个问题（因为你为什么需要一个空的测试文件）PhpUnit 会发出警告，并将其视为不成功的运行。正如我在回答中提到的那样，由于这些文件无论如何都不会运行，因此您可以安全地删除它们，或者如果它们实际上包含测试，您可能想找出 PhpUnit 无法识别它们的原因。
嗨。我有空文件的唯一原因是因为系统仍在开发中，当我的团队构建它时，测试文件将是空的。我只是觉得奇怪的是警告（我可能会添加没有断言失败）突然导致构建失败。作为一种解决方法，我刚刚在这些空文件中添加了一个 assertTrue(true, true) 测试，并指示我的团队在他们开始在该文件中工作时将其删除，我知道这并不理想。

【解决方案2】：

script:
  - vendor/bin/phpunit --configuration phpunit.xml || exit 1

你使用exit 1 - 退出 >0 总是像错误一样被线程化。

使用exit 0 或true

见http://man7.org/linux/man-pages/man3/exit.3.html

只要你不使用--fail-on-warning 调用 phpunit，它就不应该使用退出代码 >0
