🧪 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! 🚀

Start with a fresh view of investing strategy. The combination of risks and fads this quarter looks to be topping. That means the future is ready to move in.Likely, there will not be a wholesale shift. Company actions will aim to benefit from economic growth, inflationary pressures and a return of market-determined interest rates. In turn, all of that should drive the stock market and investment returns higher.
Should I buy bitcoin?
“To the extent it is used I fear it’s often for illicit finance. It’s an extremely inefficient way of conducting transactions, and the amount of energy that’s consumed in processing those transactions is staggering,” the former Fed chairwoman said. Yellen’s comments have been cited as a reason for bitcoin’s recent losses. However, Yellen’s assessment of bitcoin as a inefficient medium of exchange is an important point and one that has already been raised in the past by bitcoin bulls. Using a volatile asset in exchange for goods and services makes little sense if the asset can tumble 10% in a day, or surge 80% over the course of a two months as bitcoin has done in 2021, critics argue. To put a finer point on it, over the past 12 months bitcoin has registered 8 corrections, defined as a decline from a recent peak of at least 10% but not more than 20%, and two bear markets, which are defined as falls of 20% or more, according to Dow Jones Market Data.
