How to run Request in Laravel unit test

<code>class TestRequest()
{
    public function rules(){
        return [
            'a'=>['required','min:3'],
        ];
    }

}

//controller
public functino store(TestRequest $request)
{

}

Test.php
public function testStore()
{
    $data = [];
    $response = $this->call('POST','uri',$data);
    dd($response->getContent())
}
</code>

Every time if verification fails, $response->getStatusCode() is always 302, which is normal.
But I want to know, for example, if $data['a'] = 'a', the number of digits is less than 3, and I want to get its prompt information, how should I get it?
I am new to testing, please help me, thank you!

This test is so weird..
If you really want to get the error message, you can use Session::get. Because after verification fails, the errors object will be flash stored in the session.

For example, in your case:

<code>$response = $this->call(...);

$this->assertEquals(302, $response->getStatusCode());

dd(session('errors')->getBag('default')->first('a'));</code>

getBag obtains a MessageBag object. You can use get to obtain all verification error messages, or use first to obtain the first error message. For API documentation, see: http://laravel-china.org/api/...

--- Update

Generally, a test like this should be divided into at least two parts:
First test the validation part, using Validator, for example

<code>$data = ['a' => 'b'];
$request = new MyRequest();
$rules = $request->rules();
$validator = Validator::make($attributes, $rules);
$fails = $validator->fails();
$this->assertEquals(false, $fails);</code>

Then write the test method to test the logic behind it.

Regarding testing request in Laravel, the framework has provided many methods for testing. You can take a look at IlluminateFoundationTestingConcernsMakesHttpRequests. This basically covers all tests on request and response. Use other methods to test other parts, such as testing user authentication, testing cookie sessions, testing databases, testing queues, etc.
