Testing flashed sessions values

To test that the value is reflashed, you can use Laravel's withInput() method to flash the input data to the session, and then assert that the flashed data is present in the session after the redirect.

Here's an example test:

public function test_wallet_transaction()
{
    // Make a request to the wallet page
    $response = $this->get('/wallet');

    // Assert that the response contains the wallet form
    $response->assertSee('Wallet Form');

    // Submit the wallet form with a fake transaction ID
    $response = $this->post('/wallet', [
        'transaction_id' => 'fake_transaction_id',
    ])->assertRedirect('/original-page');

    // Assert that the transaction ID was flashed
    $this->assertSessionHas('transaction_id', 'fake_transaction_id');
}

In this example, we first make a request to the wallet page and assert that the response contains the wallet form. Then, we submit the form with a fake transaction ID and assert that the response redirects back to the original page. Finally, we assert that the transaction ID was flashed to the session using the assertSessionHas() method.

If you want to test that the value is reflashed in the wallet controller, you can add a test for the wallet controller that submits a form with a fake transaction ID and then asserts that the transaction ID is present in the session after the redirect.

Here's an example test for the wallet controller:

public function test_wallet_controller()
{
    // Submit the wallet form with a fake transaction ID
    $response = $this->post('/wallet', [
        'transaction_id' => 'fake_transaction_id',
    ])->assertRedirect('/original-page');

    // Assert that the transaction ID was reflashed
    $this->assertSessionHas('transaction_id', 'fake_transaction_id');
}

In this example, we submit the form with a fake transaction ID and assert that the response redirects back to the original page. Then, we assert that the transaction ID was reflashed in the wallet controller using the assertSessionHas() method.
