Use the Scalatra Specs2 framework to carry out the continuous integration and deployment of the Java class library
Overview:
Continuous integration (CI) and continuous deployment (CD) are the vital practices in modern software development.They can help developers deliver code to the production environment faster and increase automated testing to ensure the quality of the software.In Java development, Scalatra Specs2 is a popular framework that provides an elegant method to write and run integrated tests.This article will introduce how to use the Scalatra Specs2 framework for the continuous integration and deployment process of the Java class library.
Prerequisite:
-Famous Java Development and Maven Construction Tools
-Prop a code warehouse on the local or clouds (such as github and gitlab)
-Have a test environment that can be deployed (such as the test server)
step:
The following is the steps of continuous integration and deployment of Java class libraries using the Scalatra Specs2 framework:
1. Create Maven project:
First, create a new Java Maven project in the local environment and associate it with the code warehouse.
<groupId>com.example</groupId>
<artifactId>my-library</artifactId>
<version>1.0.0-SNAPSHOT</version>
2. Add Scalatra Specs2 dependencies:
Add Scalatra Specs2 dependencies to the pom.xml file of the project:
<dependency>
<groupId>org.scalatra</groupId>
<artifactId>specs2_2.12</artifactId>
<version>2.4.2</version>
<scope>test</scope>
</dependency>
3. Writing integrated test:
Create a new Java class and use the Scalatra Specs2 framework to write an integrated test.
import org.specs2.mutable.Specification;
public class MyLibraryIntegrationTest extends Specification {
public void testAdd() {
int result = MyLibrary.add(2, 3);
result mustEqual 5;
}
public void testSubtract() {
int result = MyLibrary.subtract(5, 2);
result mustEqual 3;
}
}
4. Configuration continuous integration tool:
Use any continuous integration tools (such as Jenkins or Travis CI) to integrate the project with the code warehouse and configure the continuous integration process.Ensure integrated testing during the construction process.
bash
mvn test
5. Automation deployment:
Establish a continuous integration and deployment streamline, and automatically deploy the constructed Java library to the test environment (such as the test server).It is recommended to use containerization technology (such as Docker) to achieve rapid deployment and environmental standardization.
bash
mvn clean install
scp target/my-library.jar user@testing-server:/path/to/deploy
in conclusion:
The use of the SCALATRA Specs2 framework for the continuous integration and deployment of the Java class library can improve development efficiency and ensure software quality.By constructing continuous integration and deployment of assembly lines, developers can deliver the code more quickly and automatically run the integration test to verify the correctness of the code.In addition, the use of automated deployment technology makes the deployment process faster and standardized.
