Java單元測試之 JUnit

引入maven依賴

<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>${junit.version}</version>
    <scope>test</scope>
</dependency>

創建測試用例（建議以方法爲單位編寫單元測試用例）

Demo.java

public class Demo {
 
    public String method() {
 
        return "This is a demo method.";
    }
}

DemoTest.java
