Best practices for rapid development and automated testing of Spring Boot

With the popularity of the Internet, the speed of software development has become very important because companies need to launch products and services as quickly as possible to meet customer needs. Therefore, developers need to use efficient tools and techniques to increase development speed while ensuring product quality. In this article, we’ll cover best practices on how to use Spring Boot for rapid development and automated testing.

Spring Boot is a development tool based on the Spring framework that allows developers to create Spring applications faster and provides a large number of automated configuration options. Spring Boot also provides out-of-the-box features such as an embedded HTTP server and Spring Data JPA integration, as well as many other common libraries and tools. Using Spring Boot can greatly simplify the application development and management process.

The following are the best practices for rapid development and automated testing of Spring Boot:

1. Use Spring Initializr to start the project

Spring Initializr is a way to quickly create Spring Boot applications Methods. You can visit the Spring Initializr website, select the required dependencies, set the project name and other options, and download the project skeleton. In addition, you can also use the initializer plug-in of an integrated development environment (IDE) such as Spring Tool Suite or IntelliJ IDEA to start the project.

The initializer can select multiple options, such as web dependencies, database dependencies, test framework, etc. This makes setting up a Spring Boot project very easy without having to manually set up various dependencies and configurations.

2. Write high-quality code and perform unit testing

High-quality code can improve the readability, maintainability and scalability of the code, and reduce potential errors. Developers should follow best practices such as using appropriate naming conventions, using meaningful comments and documentation, avoiding redundant code and duplication of code, etc. Unit tests should also be written to ensure the correctness of the code.

In Spring Boot, JUnit is one of the most popular testing frameworks, and Spring applications can be tested using Mocking frameworks such as Mockito and PowerMock. Spring Boot also provides test annotations and classes such as @SpringBootTest and @WebMvcTest to easily test controllers and other components.

3. Use integration tests to test the application

Integration tests can test the interaction between different parts of the application. This usually involves testing the interactions between multiple components, such as testing requests and responses from a web service, testing interactions between a database and an application, etc. When doing integration testing, you can test the entire application or specific components.

Spring Boot provides support for many integration tests, such as SpringBootTest, SpringBootIntegrationTest, Webdriver and Selenium, etc. Using these tools, you can easily test various parts of your Spring Boot application so that any issues can be discovered and fixed promptly.

4. Perform continuous integration and delivery

The continuous integration and delivery process can accelerate developer workflow and ensure high-quality software delivery. Continuous Integration: Developers automatically run all tests and build processes on every code commit. If a test fails or the build fails, you need to roll back your code changes. Delivery: Push the developed software to the production environment.

In order to achieve continuous integration and delivery, you can use Continuous Integration (CI) tools such as Jenkins, Travis CI and Circle CI, etc. These tools can automate the process of running tests, builds, and deployments, and push every change to your code into production. Using continuous integration and delivery can greatly reduce errors, improve code quality, and speed up the development process.

In summary, it is very important to use Spring Boot for rapid development and automated testing. This reduces developer labor costs, increases productivity and code quality, and accelerates the software development and delivery process. You can maximize the potential of Spring Boot by using best practices such as starting a project with Spring Initializr, writing high-quality code and unit tests, using integration tests, and doing continuous integration and delivery.
