如何为travis构建测试创建一个composer

Question

我正试图使用travis将build-passing状态添加到我的repo中。我一直在遵循网站上的教程。

我当前的.travis.yml文件如下所示：

language: php
php:
- 7.0
- 7.1
- 7.2
matrix:
include:
- php: 7.2
dist: precise
sudo: false
before_script: composer install
script: phpunit

我的作曲家是这样的：

{
"name": "ArrayList",
"description": "A simple library for arrays to use lambda.",
"homepage": "https://github.com/Jaquarh/ArrayList",
"authors": [
{
"name": "Kyle Jeynes",
"email": "[e-mail]",
"role": "Developer"
}
],
"license": "BSD-3-Clause",
"require": {
"php": ">=7.2.0"
},
"autoload": {
"psr-4": {
"Jaquarh\ArrayList\": "test"
}
},
"require-dev": {
"phpunit/phpunit": " 4.8.35"
}
}

然而，当我开始构建我的回购时，它失败了，出现了这个错误

命令"phpunit"以2退出。

原始输出(如果有用，看起来像这样(

文档中指出，我需要为travis创建一个composer来执行我的指令。我认为这就像一次"测试"。

我创建了一个包含所有库的新文件，并在test/travis.php:中进行了一个测试

require_once '../ArrayList.php';
$myArray = new ArrayList([
['id' => 1, 'username' => 'foo', 'privilidges' => ['can_read' => 1, 'can_write' => 0], 'incomming' => ''],
['id' => 2, 'username' => 'bar', 'privilidges' => ['can_read' => 1, 'can_write' => 1], 'incomming' => 'Hi everyone!']
]);
$myArray->where(function($x) {
$privilidges = (object) $x['privilidges'];
return $privilidges->can_write;
})->getFirstOrDefault()
->ifPresent(function($x) {
if(!empty(($incomming = $x['incomming']))) echo $incomming;
});

然而，这不是一个作曲家，我不知道如何让特拉维斯执行这一点。

任何想法或帮助都将不胜感激，这是我第一次使用Travis，文档对创建Travis构建的测试环境没有帮助。

这是我的存储库，如果查看它有任何帮助的话。

在更新我的composer以使用PHP 7.1.11之后，我得到了这个错误

您的需求无法解析为一组可安装的软件包。

Answer 1

我设法弄清楚PHPUnit和composer需要什么。

我更改了.travis.yml以测试所有PHP版本并执行运行测试所需的脚本。

language: php
php:
- 5.4
- 5.5
- 5.6
- 7.0
- 7.1
- 7.2
matrix:
include:
- php: 5.3
dist: precise
sudo: false
before_script: composer install
script: phpunit

测试需要配置，所以在一个新文件phpunit.xml.dist中，我放了这个：

<?xml version="1.0" encoding="UTF-8"?>
<phpunit backupGlobals="false"
backupStaticAttributes="false"
colors="true"
convertErrorsToExceptions="true"
convertNoticesToExceptions="true"
convertWarningsToExceptions="true"
processIsolation="false"
stopOnFailure="false"
syntaxCheck="false"
bootstrap="tests/bootstrap.php"
>
<testsuites>
<testsuite name="PHP ArrayList Test Suite">
<directory>./tests</directory>
</testsuite>
</testsuites>
</phpunit>

接下来，我为这个配置创建了一个名为run-tests.sh:的脚本

php --version
php phpunit.phar --configuration phpunit.xml.dist

我更新了我的composer，使用PHP 5.3作为开始，如下所示：

{
"name": "ArrayList",
"description": "A simple library for arrays to use lambda.",
"homepage": "https://github.com/Jaquarh/ArrayList",
"authors": [
{
"name": "Kyle Jeynes",
"email": "[e-mail]",
"role": "Developer"
}
],
"license": "MIT",
"require": {
"php": ">=5.3.0"
},
"autoload": {
"psr-4": {
"Jaquarh\ArrayList\": "src"
}
},
"require-dev": {
"phpunit/phpunit": " 4.8.35"
}
}

最后，我构建了包括bootstrap.php和autoload.php.dist:的测试

if (file_exists($file = __DIR__ . '/autoload.php')) {
require_once $file;
} elseif (file_exists($file = __DIR__ . '/autoload.php.dist')) {
require_once $file;
}
// if the library is the project, try to use the composer's autoload for the tests
$composerAutoload = __DIR__ . '/../vendor/autoload.php';
if (is_file($composerAutoload)) {
include $composerAutoload;
} else {
die('Unable to find autoload.php file, please use composer to load dependencies:
wget http://getcomposer.org/composer.phar
php composer.phar install
Visit http://getcomposer.org/ for more information.
');
}
