Laravel PestUnit – Failed asserting that 404 is identical to 200

I’m trying to use the Pest PHP framework for testing, but I’m unable to perform a simple test.

it('can view home page', function () {
    $response = $this->get('/');

    expect($response->status())->toBe(200);
});

I always get the error:

Failed asserting that 404 is identical to 200.

It seems that the URL is not being correctly read. Here’s my files configuration:

.env file

APP_NAME="My software name"
APP_ENV=local
APP_KEY=base64:abchdX+Hm/LYphNZIBx942SFZoJYzGUFGidCxQifqMw=
APP_DEBUG=true
APP_URL=http://localhost/mysoftware

phpunit.xml

        <env name="SESSION_DRIVER" value="array"/>
        <env name="TELESCOPE_ENABLED" value="false"/>
    </php>
</phpunit>

I’ve read some topics such as:

https://www.reddit.com/r/laravel/comments/kivwyr/laravel_phpunit_test_pointing_to_wrong_url/

Configuring Laravel 5 Unit Test URL with phpunit.xml

Laravel phpunit not getting right url

Where I end up trying to rectify my phpunit.xml file by appending:

<env name="APP_URL" value="http://localhost/mysoftware"/>

But the error persists. What can I do to debug further?

Edit 1) – My routes files indeed have both / & /login routes and it doesn’t matter if the test is pointing to home route or login route, the error is the same.

it('can view home page', function () {
    $response = $this->get('/');

    expect($response->status())->toBe(200);
});

it('can view login page', function () {
    $response = $this->get('/login');

    expect($response->status())->toBe(200);
});
