Call to undefined method ExampleTest::assertStatus()

Question

I'm using Lumen for api building and also want to write unit test cases for that. But the problem I'm facing is not a single assert method is working. Like assertStatus(), assertNotFound(), assertJson(), etc. All of them giving error as Call to undefined method ExampleTest::assertMethod(). Below is my ExampleTest file.

<?php

use Laravel\Lumen\Testing\DatabaseMigrations;
use Laravel\Lumen\Testing\DatabaseTransactions;

class ExampleTest extends TestCase
{
    /**
     * A basic test example.
     *
     * @return void
     */
    public function testExample()
    {
        $this->get('/');

        $this->assertEquals(
            $this->app->version(), $this->response->getContent()
        );
    }

    /** @test */
    public function testExample2()
    {
        $response = $this->get('/');

        //getting error here
        $response->assertStatus(200);
    }
}

I'm wring test cases for the first time in Lumen. Plese guide me through this process.

Some of the ways to assert are different if you are using Lumen's Laravel\Lumen\Testing\TestCase vs Laravel's default Illuminate\Foundation\Testing\TestCase.

If you want to assertStatus for Illuminate\Foundation\Testing\TestCase:

public function testHomePage()
    {
        $response = $this->get('/');

        $response->assertStatus(200);
    }

The same for Laravel\Lumen\Testing\TestCase :

public function testHomePage()
    {
        $response = $this->get('/');

        $this->assertEquals(200, $this->response->status());
    }
