ModelFactory: Error: Call to a member function connection() on null

Question

在尝试使用 ModelFactory 填充数据库时我遇到了这个错误，自从过去六个小时以来我一直在查找，似乎无法修复它。

我的测试运行这个：

$books = factory('App\Book', 2)->create();

错误信息是这样的：

There was 1 error:

1) Tests\App\Http\Controllers\BooksControllerTest::testIndexReturnsCollection
Error: Call to a member function connection() on null

在我的 bootstrap/app.php 我有第 26 和 28 行，像这样：

$app->withFacades();

$app->withEloquent();

而我的phpunit.xml是这样的：

<?xml version="1.0" encoding="UTF-8"?>
<phpunit backupGlobals="false"
         backupStaticAttributes="false"
         bootstrap="bootstrap/app.php"
         colors="true"
         convertErrorsToExceptions="true"
         convertNoticesToExceptions="true"
         convertWarningsToExceptions="true"
         processIsolation="false"
         stopOnFailure="false">
    <testsuites>
        <testsuite name="Application Test Suite">
            <directory suffix="Test.php">./tests</directory>
        </testsuite>
    </testsuites>
    <filter>
        <whitelist processUncoveredFilesFromWhitelist="true">
            <directory suffix=".php">./app</directory>
        </whitelist>
    </filter>
    <php>
        <env name="APP_ENV" value="testing"/>
        <env name="CACHE_DRIVER" value="array"/>
        <env name="QUEUE_DRIVER" value="sync"/>
        <env name="DB_DATABASE" value="rlp_rlfpsfactory"/>
    </php>
</phpunit>

我是否需要在 phpunit xml 文件的 php 部分添加任何其他内容？

Answer 1

在一整天都没有运气之后，多亏了@ChrisSprague，我将 Lumen 降级到 5.6 并且它起作用了。

步骤：

在composer.json文件中更改

"laravel/lumen-framework": "5.7.*"

至

"laravel/lumen-framework": "5.6.*"

删除您的 vendor 文件夹
做composer install
运行再次测试！

如果它仍然不起作用，请确保您的 phpunit.xml 文件

中有正确的测试数据库详细信息

我的看起来像：

<?xml version="1.0" encoding="UTF-8"?>
<phpunit backupGlobals="false"
         backupStaticAttributes="false"
         bootstrap="bootstrap/app.php"
         colors="true"
         convertErrorsToExceptions="true"
         convertNoticesToExceptions="true"
         convertWarningsToExceptions="true"
         processIsolation="false"
         stopOnFailure="false">
    <testsuites>
        <testsuite name="Application Test Suite">
            <directory suffix="Test.php">./tests</directory>
        </testsuite>
    </testsuites>
    <filter>
        <whitelist processUncoveredFilesFromWhitelist="true">
            <directory suffix=".php">./app</directory>
        </whitelist>
    </filter>
    <php>
        <env name="APP_ENV" value="testing"/>
        <env name="CACHE_DRIVER" value="array"/>
        <env name="QUEUE_DRIVER" value="sync"/>
        <env name="SESSION_DRIVER" value="array"/>
        <env name="DB_DATABASE" value="rlp_rlfpsfactory"/> <!-- this is testing database -->
        <env name="DB_USERNAME" value="root"/>
        <env name="DB_PASSWORD" value=""/>
    </php>
</phpunit>
