Laravel 8: Test MainClassTest from a ChildClassTest - php

Question

How to test the MainClassTest Methods from a ChildClassTest extending it, since the child class will perform the same test scenarios but given with different data
Sample of code
<?php
namespace Tests\Feature\Modules;
use Tests\TestCase;
class BaseControllerTest extends TestCase
{
/**
* A basic feature test example.
*
* #return void
*/
public function test_common_method_for_each_child()
{
// process
}
}
<?php
namespace Tests\Feature\Modules;
use Tests\TestCase;
class ChildControllerTest extends BaseControllerTest {
public function test_unique_method() {
// process
}
}
<?php
namespace Tests\Feature\Modules;
use Tests\TestCase;
class Child1ControllerTest extends BaseControllerTest {
public function test_unique_method() {
// process
}
}
So when run the php artisan test, should see a list of test
ChildControllerTest->test_common_method_for_each_child
ChildControllerTest->test_unique_method
Child1ControllerTest->test_common_method_for_each_child
Child1ControllerTest->test_unique_method

Answer 1

The tests inside the parent will be ran when you'll run your child class tests, what you did should already work.
If that's not the case, can you edit your question with the PHPUnit command you are running and its output?
However, you should make your base class abstract:
abstract class BaseControllerTest extends TestCase
{
/**
* A basic feature test example.
*
* #return void
*/
public function test_common_method_for_each_child()
{
// process
}
}
If you don't do this, this class will also be called alone, out of the context of a child, during the test suite (which doesn't seem to be what your goal).
