Unit testing Feign clients

Let's create a unit test class; this test class can have several test methods but in this example, we have created three @Test methods, to test our client. The test will use static imports from the org.hamcrest.CoreMatchers.* and org.junit.Assert.* packages:

@Test 
public void findAllAccountTest() throws Exception { 
   List<Account> accounts = accountService.findAll(); 
   assertTrue(accounts.size() > 4); 
} 
  
@Test 
public void findOneAccountTest() throws Exception { 
    Account account = accountService.findByAccountId(1001); 
    assertThat(account.getCustmer().getCustomerName(), 
    containsString("Arnav")); 
} 
  
@Test 
public void createAccountTest() throws Exception { 
    Account account = new Account(1001, 2304.32, 100, 'SAVING', 
   'HDFC0011', 'HDFC') 
    accountService.create(account); 
    account = accountService.findByAccountId(1001); 
  
    assertThat(account.getBank(), containsString("HDFC")); 
} 

We have written unit test cases to...
