Laravel - 测试重定向后会发生什么

Question

我有一个控制器,在提交电子邮件后,执行重定向到家庭,如下所示:

return Redirect::route('home')->with("message", "Ok!");

我正在为它编写测试,我不知道如何使phpunit遵循重定向,测试成功消息:

public function testMessageSucceeds() {
    $crawler = $this->client->request('POST', '/contact', ['email' => 'test@test.com', 'message' => "lorem ipsum"]);

    $this->assertResponseStatus(302);
    $this->assertRedirectedToRoute('home');

    $message = $crawler->filter('.success-message');

    // Here it fails
    $this->assertCount(1, $message);
}

如果我替换控制器上的代码,我删除前两个断言,它的工作原理

Session::flash('message', 'Ok!');
return $this->makeView('staticPages.home');

但我想用Redirect::route.有没有办法让PHPUnit遵循重定向？

Answer 1

你可以让PHPUnit跟随重定向:

Laravel> = 5.5.19:

$this->followingRedirects();

Laravel <5.4.12:

$this->followRedirects();

用法:

$response = $this->followingRedirects()
    ->post('/login', ['email' => 'john@example.com'])
    ->assertStatus(200);

注意:需要为每个请求明确设置.

对于这两者之间的版本:

Laravel 8 已测试

$response = $this->post'/contact', ['email' => 'test@test.com', 'message' => "lorem ipsum"]);

$response->assertStatus(302);
$response->assertRedirect('home');

$this->followRedirects($response)->assertSee('.success-message');
//or
$this->followRedirects($response)->assertSee('Ok!');

为我工作，希望有帮助。

您可以通过这种方式告诉抓取工具遵循重定向:

$crawler = $this->client->followRedirect();

所以在你的情况下,这将是这样的:

public function testMessageSucceeds() {
    $this->client->request('POST', '/contact', ['email' => 'test@test.com', 'message' => "lorem ipsum"]);

    $this->assertResponseStatus(302);
    $this->assertRedirectedToRoute('home');

    $crawler = $this->client->followRedirect();

    $message = $crawler->filter('.success-message');

    $this->assertCount(1, $message);
}
