How to quickly use Junit Jupiter (Aggregator) framework
Junit Jupiter is a powerful Java unit test framework that provides developers with rich functions and flexibility.This article will introduce how to quickly use the Junit Jupiter (Aggregator) framework and provide some Java code examples.
1. Install Junit Jupiter (Aggregator) framework
First, we need to install the Junit Jupiter (Aggregator) framework in the project.You can add the following dependencies through Maven or Gradle:
Maven dependencies:
<dependency>
<groupId>org.junit.jupiter</groupId>
<artifactId>junit-jupiter</artifactId>
<version>5.8.0</version>
<scope>test</scope>
</dependency>
Gradle dependencies:
groovy
testImplementation 'org.junit.jupiter:junit-jupiter:5.8.0'
2. Create a test class and test method
Create a new Java class and add the `@test` to it to indicate that the method is a test method.Inside the test method, various assertions can be used to verify the expectations of the code.
import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;
public class MyTestClass {
@Test
public void testAddition() {
int result = 2 + 2;
Assertions.assertEquals(4, result);
}
}
3. Run testing
The running test is very simple.Using Junit Jupiter (Aggregator), you can run a single test class by testing the operator (such as Intellij IDEA or Eclipse), or run the entire test kit by constructing tools (such as Maven or Gradle).
If you use Intellij IDEA, you can right -click the strike test class and select "Run 'MyTestClass'" to run the test.The test results will be displayed in running views.
4. Explore more functions
Junit Jupiter (Aggregator) provides many functions and annotations to help us better write and organize test code.Here are some commonly used function examples:
-`@beforeeach` and `@afterreach` Note: execute a specific code before each test method is running.
-`@BeForeall` and`@afterrall `Note: Perform specific code before and after all test methods are running.
-`@DisplayName` Note: Provide a custom display name for the test method.
-`@Disabled` Note: Mark a test method as a disabled state.
-`@Nested` Note: Allows other test classes in the test class to better organize test code.
These are just examples of functions and annotations provided by the Junit Jupiter (Aggregator) framework, as well as more functions that can be explored and used.Download the official documentation of JUNIT JUPITER (GGREGATOR) to learn more about the detailed information and examples of the framework.
Through this article, you should now be able to quickly use the Junit Jupiter (Aggregator) framework and start writing a reliable and efficient unit test.I wish you success in your Java project!
