The @RunWith(SpringRunner.class) annotation provides Spring ApplicationContext and get beans injected into your test instance:
@RunWith(SpringRunner.class)@SpringBootTestpublic class MyTestsClass { @Test public void testMethod() { ... }}
First, we will create our first test case, which will test the major functionality of your application ...
