🧪 Today, let's dive into the essentials of testing in Spring Boot! Whether you’re building REST APIs or simple web applications, testing is crucial to ensure reliability.
Here's a breakdown of the key concepts I find valuable:
1. Types of Tests: - Unit Tests: Focus on individual components. - Integration Tests: Check the interaction between components. - End-to-End Tests: Validate the whole system’s functionality.
2. Annotations You Should Know: - @SpringBootTest: Used for loading the application context. - @WebMvcTest: Focused on testing controllers only. - @MockBean: To create mock objects in your tests.
3. Basic Example:
@RunWith(SpringRunner.class) @SpringBootTest public class MyServiceTests {
@Autowired private MyService myService;
@Test public void testServiceMethod() { assertEquals("Expected Output", myService.serviceMethod()); } }
📅 Remember, writing tests early helps identify issues sooner, saving time and effort in the long run. Happy coding! 🚀

Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. “Once a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,” says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means it’s not controlled by any one organization. “It’s like a Google Doc that anyone can work on,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. “Nobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.”
The S&P 500 slumped 1.8% on Monday and Tuesday, thanks to China Evergrande, the Chinese property company that looks like it is ready to default on its more-than $300 billion in debt. Cries of the next Lehman Brothers—or maybe the next Silverado?—echoed through the canyons of Wall Street as investors prepared for the worst.
