phpunit测试返回302进行错误验证，为什么不返回422 [英] phpunit test returns 302 for bad validation, why not 422

问题描述

我有一个请求类，该类对于发布请求失败.当我用ajax调用它时，我得到422，因为验证规则失败.但是，当我使用phpunit测试具有相同值的相同路由时，它会返回302.

I have a request class that fails for a post request. When I call it with ajax I get an 422 because the validation rules failed. But when I use phpunit for test for the same route with same values, it returns a 302.

我也没有收到诸如需要foobar字段"之类的错误消息，只是302.

I also get no error messages like "field foobar is required" just the 302.

那么如何获取错误消息以检查它们是否相等?

So how can I get the error messages to check if they are equals or not?

这是我的测试代码:

//post exam
$this->post('modul/foo/exam', [
    'date' => '2016-01-01'
])
    ->assertResponseStatus(200);

//post exam again
$this->post('modul/foo/exam', [
    'date' => '2016-01-01'
])
    ->assertResponseStatus(302); //need to get 422 with th errors because its an api

推荐答案

FormRequest上的验证失败时，它将检查请求是否为ajax或是否接受json响应.如果是这样，它将返回带有422状态代码的json响应.如果不是，它将返回重定向到指定的URL(默认为以前的URL).因此，为了获得您要查找的失败的响应(422)，您需要发出json请求或ajax请求.

When the validation on the FormRequest fails, it checks to see if the request was ajax or if it accepts a json response. If so, it will return a json response with the 422 status code. If not, it will return a redirect to a specified url (previous, by default). So, in order to get the response on failure you're looking for (422), you need to make a json request or an ajax request.

要发出json请求，您应该使用json()方法:

To make a json request, you should use the json() method:

//post exam
$this->json('POST', 'modul/foo/exam', [
        'date' => '2016-01-01'
    ])
    ->assertResponseStatus(200);

//post exam again
$this->json('POST', 'modul/foo/exam', [
        'date' => 'some invalid date'
    ])
    ->assertResponseStatus(422);

如果您认为比将方法作为参数传递看起来更干净，则还有getJson()，postJson()，putJson()，patchJson()和deleteJson()快捷方法.

There are also getJson(), postJson(), putJson(), patchJson(), and deleteJson() shortcut methods if you think that looks cleaner than passing the method as a parameter.

//post exam
$this->postJson('modul/foo/exam', [
        'date' => '2016-01-01'
    ])
    ->assertResponseStatus(200);

AJAX

要发出ajax请求，您需要添加ajax标头.为此，您可以继续使用post()方法:

//post exam
$this->post('modul/foo/exam', [
        'date' => '2016-01-01'
    ], ['HTTP_X_REQUESTED_WITH' => 'XMLHttpRequest'])
    ->assertResponseStatus(200);

//post exam again
$this->post('modul/foo/exam', [
        'date' => 'some invalid date'
    ], ['HTTP_X_REQUESTED_WITH' => 'XMLHttpRequest'])
    ->assertResponseStatus(422);
