本文向您展示如何使用JUnit 5根据条件启用或禁用测试。

*PS已通过JUnit 5.5.2测试*

## 1.操作系统 ##

1.1通过`@EnabledOnOs`和`@DisabledOnOs`注释基于特定操作系统启用或禁用的测试。

OperatingSystemTest.java

package com.mkyong.conditional;
    
    import org.junit.jupiter.api.Test;
    import org.junit.jupiter.api.condition.DisabledOnOs;
    import org.junit.jupiter.api.condition.EnabledOnOs;
    import org.junit.jupiter.api.condition.OS;
    
    public class OperatingSystemTest {
    
        @Test
        @EnabledOnOs({OS.LINUX, OS.WINDOWS})
        void onLinuxOrWindows() {
            System.out.println("Run this on Linux or Windows!");
        }
    
        @Test
        @EnabledOnOs({OS.WINDOWS})
        void onWindows() {
            System.out.println("Run this on Windows!");
        }
    
        @Test
        @DisabledOnOs(OS.WINDOWS)
        void notOnWindows() {
            System.out.println("Do not run this on Windows!");
        }
    
        @Test
        @DisabledOnOs({OS.WINDOWS, OS.AIX, OS.SOLARIS, OS.MAC})
        void notOnWindowsOrAixOrSolarisOrMac() {
            System.out.println("Do not run this on Windows, AIX, Solaris or MAC!");
        }
    
    }

输出–使用Windows操作系统进行测试。

## 2. Java运行时环境 ##

2.1通过`@EnabledOnJre`和`@DisabledOnJre`批注基于特定Java运行时环境（JRE）启用或禁用的测试。

JreTest.java

package com.mkyong.conditional;
    
    import org.junit.jupiter.api.Test;
    import org.junit.jupiter.api.condition.DisabledOnJre;
    import org.junit.jupiter.api.condition.EnabledOnJre;
    import org.junit.jupiter.api.condition.JRE;
    
    public class JreTest {
    
        @Test
        @EnabledOnJre(JRE.JAVA_9)
        void onJava9() {
            System.out.println("Run this on Java 9");
        }
    
        @Test
        @EnabledOnJre({JRE.JAVA_12, JRE.JAVA_13})
        void onJava12OrJava13() {
            System.out.println("Run this on Java 12 or Java 13");
        }
    
        @Test
        @DisabledOnJre(JRE.JAVA_9)
        void notOnJava9() {
            System.out.println("Do not run this on Java 9");
        }
    
    }

输出–使用Java 13进行测试

## 3.系统属性 ##

3.1根据JVM系统属性中通过`@EnabledIfSystemProperty`和`@DisabledIfSystemProperty`批注`named`的值，启用或禁用测试。

SystemPropertyTest.java

package com.mkyong.conditional;
    
    import org.junit.jupiter.api.Test;
    import org.junit.jupiter.api.condition.DisabledIfSystemProperty;
    import org.junit.jupiter.api.condition.EnabledIfSystemProperty;
    
    import java.util.Properties;
    
    public class SystemPropertyTest {
    
        @Test
        @EnabledIfSystemProperty(named = "java.vm.name", matches = ".*OpenJDK.*")
        void onOpenJDK() {
            System.out.println("Run this on OpenJDK!");
        }
    
        @Test
        @DisabledIfSystemProperty(named = "user.country", matches = "MY")
        void notOnCountryMalaysia() {
            System.out.println("Do not run this on country code MY");
        }
    
        @Test
        void printSystemProperties() {
            Properties properties = System.getProperties();
            properties.forEach((k, v) -> System.out.println(k + ":" + v));
        }
    
    }

## 4.环境变量 ##

4.1根据环境属性中通过`@EnabledIfEnvironmentVariable`和`@DisabledIfEnvironmentVariable`批注`named`的值来启用或禁用测试。

EnvVariableTest.java

package com.mkyong.conditional;
    
    import org.junit.jupiter.api.Test;
    import org.junit.jupiter.api.condition.DisabledIfEnvironmentVariable;
    import org.junit.jupiter.api.condition.EnabledIfEnvironmentVariable;
    
    import java.util.Map;
    
    public class EnvVariableTest {
    
        @Test
        @EnabledIfEnvironmentVariable(named = "PROCESSOR_IDENTIFIER", matches = ".*Intel64 Family 6.*")
        void onIntel64() {
            System.out.println("Run this on Intel6 Family 6 only.");
        }
    
        @Test
        @EnabledIfEnvironmentVariable(named = "NUMBER_OF_PROCESSORS", matches = "8")
        void onProcessor8() {
            System.out.println("Run this if it has 8 processors.");
        }
    
        @Test
        @DisabledIfEnvironmentVariable(named = "CURRENT_ENV", matches = ".*development.*")
        void notOnDeveloperPC() {
            System.out.println("Do not run this if env variables 'CURRENT_ENV' matches .*development.* ");
        }
    
        @Test
        void printEnvironmentProperties() {
            Map<String, String> env = System.getenv();
            env.forEach((k, v) -> System.out.println(k + ":" + v));
        }
    
    
    }
