Spring boot unit test (IV) executed according to conditions

2022-01-27 00:11:45 Java Xiaohai

Spring Boot The test can be controlled to execute under certain conditions , Same as @Tag Filter different by tag .

One 、Java Environmental Science

  • @EnabledOnJre: Specify multiple JRE edition , Only the current test environment JRE The version is tested only in this range .
  • @DisabledOnJre: Specify multiple JRE edition , Only the current test environment JRE Testing is performed only when the version is not in this range .
  • @EnabledForJreRange: To specify a JRE Version range , Only the current test environment JRE The version is tested only in this range .
  • @DisabledForJreRange: To specify a JRE Version range , Only the current test environment JRE Testing is performed only when the version is not in this range .
package com.example.demo;

import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.condition.DisabledForJreRange;
import org.junit.jupiter.api.condition.DisabledOnJre;
import org.junit.jupiter.api.condition.EnabledForJreRange;
import org.junit.jupiter.api.condition.EnabledOnJre;
import org.junit.jupiter.api.condition.JRE;

public class UnitTest {

    @Test
    @EnabledOnJre({ JRE.JAVA_11, JRE.JAVA_17 })
    public void enabledOnJava11And17Test() {
        System.out.println("Method[enabledOnJava11And17Test] executed.");
    }

    @Test
    @DisabledOnJre({ JRE.JAVA_17 })
    public void disabledOnJava17Test() {
        System.out.println("Method[disabledOnJava17Test] executed.");
    }

    @Test
    @EnabledForJreRange(min = JRE.JAVA_8, max = JRE.JAVA_17)
    public void enabledForJava8To17() {
        System.out.println("Method[enabledForJava8To17] executed.");
    }

    @Test
    @DisabledForJreRange(min = JRE.JAVA_11, max = JRE.JAVA_17)
    public void disabledForJava11To17() {
        System.out.println("Method[disabledForJava11To17] executed.");
    }
}
 Copy code 

Two 、 operating system

  • EnabledOnOs: Execute the test when the current system is the specified operating system .
  • DisabledOnOs: When the current system is the specified operating system, the test will not be executed .
package com.example.demo;

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 UnitTest {

    @Test
    @EnabledOnOs(OS.WINDOWS)
    public void enabledOnWindows() {
        System.out.println("Windows Execute under the operating system ");
    }

    @Test
    @DisabledOnOs(OS.LINUX)
    public void disabledOnLinux() {
        System.out.println("Linux Do not execute... Under the operating system ");
    }
}
 Copy code 

3、 ... and 、 System attribute

  • @EnabledIfSystemProperty: The test is executed when the current system matches the specified system attribute name and expected value .
  • @DisabledIfSystemProperty: The test is not executed when the current system matches the specified system attribute name and expected value .
package com.example.demo;

import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.condition.DisabledIfSystemProperty;
import org.junit.jupiter.api.condition.EnabledIfSystemProperty;

public class UnitTest {

    @Test
    @EnabledIfSystemProperty(named = "user.language", matches = "zh")
    public void enabledIfSystemPropertyUserLanguageIsZh() {
        System.out.println(" The current operating system user language is Chinese ");
    }

    @Test
    @DisabledIfSystemProperty(named = "os.arch", matches = ".*64.*")
    public void disabledIfSystemProperty() {
        System.out.println("64 Bit operating system does not execute ");
    }
}
 Copy code 

Four 、 environment variable

  • EnabledIfEnvironmentVariable: The test is executed when the current system matches the specified environment variable name and expected value .
  • DisabledIfEnvironmentVariable: The current system does not execute the test when it matches the specified environment variable name and expected value .
package com.example.demo;

import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.condition.DisabledIfEnvironmentVariable;
import org.junit.jupiter.api.condition.EnabledIfEnvironmentVariable;

public class UnitTest {

    @Test
    @EnabledIfEnvironmentVariable(named = "JAVA_HOME", matches = ".*")
    public void enabledIfEnvironmentVariable() {
        System.out.println(" environment variable JAVA_HOME Execute when present ");
    }

    @Test
    @DisabledIfEnvironmentVariable(named = "JAVA_HOME", matches = ".*17.*")
    public void disabledIfEnvironmentVariable() {
        System.out.println(" environment variable JAVA_HOME There are characters 17 When does not perform ");
    }
}
 Copy code 

5、 ... and 、 Custom conditions

JUnit 5.7 Later versions provide @EnabledIf and @DisabledIf Two annotations implement user-defined test execution conditions .@EnabledIf and @DisabledIf The annotation takes a method name as a parameter , Method return value type is boolean.

package com.example.demo;

import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.condition.DisabledIf;
import org.junit.jupiter.api.condition.EnabledIf;

public class UnitTest {

    @Test
    @EnabledIf("customCondition")
    public void enabledIf() {
        System.out.println("Method[enabledIf] executed.");
    }

    @Test
    @DisabledIf("customCondition")
    public void disabledIf() {
        System.out.println("Method[disabledIf] executed.");
    }

    private boolean customCondition() {
        return true;
    }
}
 Copy code 

EnabledIf and @DisabledIf Annotations can be used not only for methods , It can also be used on classes , If it is used on a class , be @EnabledIf and @DisabledIf The method specified by the annotation parameter must be static .

package com.example.demo;

import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.condition.EnabledIf;

@EnabledIf("customCondition")
public class UnitTest {

    @Test
    public void enabledIf() {
        System.out.println("Method[enabledIf] executed.");
    }

    private static boolean customCondition() {
        return true;
    }
}
 Copy code 

If @EnabledIf and @DisabledIf The method specified by the annotation parameter is not in the same class as the test method , The full path of the method must be specified : Package name . Class name # Method name .

package com.example.demo;

public class CustomCondition {

    public static boolean customCondition() {
        return true;
    }
}
 Copy code 
package com.example.demo;

import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.condition.EnabledIf;

@EnabledIf("com.example.demo.CustomCondition#customCondition")
public class UnitTest {

    @Test
    public void enabledIf() {
        System.out.println("Method[enabledIf] executed.");
    }
}
