change .env information in laravel test-CodePudding

I'm making an automatic email sending program in laravel and I need to test it with different email providers. I'm doing the tests with PHPUnit and I wanted to know if there is any way to change the variables of the .env file such as 'mail_host' for example directly in the test.

I tried to use the following code to change but it didn't work:

config([
  'MAIL_HOST' => ' smtp.mail.yahoo.com'
]);

I'm using laravel version 8.79 and PHP 7.4

You can change any .env variable during tests in Laravel from the phpunit.xml file.

Here is an example of my XML:

<?xml version="1.0" encoding="UTF-8"?>
<phpunit>
  <coverage processUncoveredFiles="true">
    <include>
      <directory suffix=".php">./app</directory>
    </include>
  </coverage>
  <testsuites>
    <testsuite name="Unit">
      <directory suffix="Test.php">./tests/Unit</directory>
    </testsuite>
    <testsuite name="Feature">
      <directory suffix="Test.php">./tests/Feature</directory>
    </testsuite>
  </testsuites>
  <PHP>
    <!--  Here you can change any PHP env   -->
    <env name="APP_ENV" value="testing"/>
    <env name="BCRYPT_ROUNDS" value="4"/>
    <env name="CACHE_DRIVER" value="array"/>
    <env name="MAIL_DRIVER" value="array"/>
    <env name="QUEUE_CONNECTION" value="sync"/>
    <env name="SESSION_DRIVER" value="array"/>
    <env name="DB_CONNECTION" value="testing"/>
  </php>
</phpunit>

you can change directly int the .env file MAIL_HOST variable. If you are testing I recommend to set up a mailtrap account, which is ideal for testing see more information https://mailtrap.io https://www.itsolutionstuff.com/post/laravel-send-mail-using-mailtrap-exampleexample.html

If you need to dynamically change an env variable, you can change it using $_ENV['variable'], but you should never do so using that.

To solve that issue, you have to use the config helper, as you did, but instead of using the environment variable as a key, use the real config path.

For example, if you have this config file (config/testing.php) like this:

<?php

return [
    'mail' => [
        'host' => env('TESTING_MAIL_HOST', 'fake.host.com'),
    ],
];

You can do config(['testing.mail.host' => 'new.domain.com']); inside your test before you run the code you want to test, so when you use config('testing.mail.host'); in the real code, you will get new.domain.com value back instead of fake.host.com or whatever you were using for TESTING_MAIL_HOST.

Remember that this is an example, TESTING_MAIL_HOST does not exist.
