php - Mockery 在测试 Laravel 门面时抛出 NoMatchingExpectationException

Question

我正在尝试测试我的一个服务类，但无法通过 PHPUnit 测试。

测试失败的相关部分:

File::shouldReceive('put')->with('app/storage/logs/laravel.log', 'New content.')->once()->andReturn(12);

我要测试的代码(简化版):

$date = Carbon::now()->toDayDateTimeString();
$fileContent = sprintf(
    "Last maintenance check performed at %s. The old logs have been deleted.\n\n",
    $date
);

// $this->fileLocation refers to a string 'app/storage/logs/laravel.log'
return File::put($this->fileLocation, $fileContent);

我遇到的异常:

Time: 1.72 seconds, Memory: 17.50Mb

There was 1 error:

1) Unit\Services\Maintenance\LogCleanerTest::testLogsAreClearedAndUpdated
Mockery\Exception\NoMatchingExpectationException: No matching handler found for Mockery_0_Illuminate_Filesystem_Filesystem::put("app/storage/logs/laravel.log", "Last maintenance check performed at Tue, Jul 15, 2014 12:16 PM. The old logs have been deleted.
"). Either the method was unexpected or its arguments matched no expected argument list for this method

有人可以解释我做错了什么吗？任何帮助将不胜感激。

类似于:

File::shouldReceive('put')->with('app/storage/logs/laravel.log', 'Last maintenance check performed at')->once()->andReturn(12);

应该可以。你在 mock 期待“新内容”。作为第二个参数，但您的代码正在发送“上次维护检查...”。我相信如果 mockery 不能匹配确切的字符串，默认情况下会尝试正则表达式匹配。
