🧪 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! 🚀

Tata Power whose core business is to generate, transmit and distribute electricity has made no money to investors in the last one decade. That is a big blunder considering it is one of the largest power generation companies in the country. One of the reasons is the company's huge debt levels which stood at ₹43,559 crore at the end of March 2021 compared to the company’s market capitalisation of ₹44,447 crore.
Export WhatsApp stickers to Telegram on Android
From the Files app, scroll down to Internal storage, and tap on WhatsApp. Once you’re there, go to Media and then WhatsApp Stickers. Don’t be surprised if you find a large number of files in that folder—it holds your personal collection of stickers and every one you’ve ever received. Even the bad ones.Tap the three dots in the top right corner of your screen to Select all. If you want to trim the fat and grab only the best of the best, this is the perfect time to do so: choose the ones you want to export by long-pressing one file to activate selection mode, and then tapping on the rest. Once you’re done, hit the Share button (that “less than”-like symbol at the top of your screen). If you have a big collection—more than 500 stickers, for example—it’s possible that nothing will happen when you tap the Share button. Be patient—your phone’s just struggling with a heavy load.On the menu that pops from the bottom of the screen, choose Telegram, and then select the chat named Saved messages. This is a chat only you can see, and it will serve as your sticker bank. Unlike WhatsApp, Telegram doesn’t store your favorite stickers in a quick-access reservoir right beside the typing field, but you’ll be able to snatch them out of your Saved messages chat and forward them to any of your Telegram contacts. This also means you won’t have a quick way to save incoming stickers like you did on WhatsApp, so you’ll have to forward them from one chat to the other.
