When tests depend on OS-specific behavior (file paths, process APIs, shells), you can restrict them to certain operating systems.

Overview

• @EnabledOnOs runs the test only on the specified OS(es).
• @DisabledOnOs skips tests on the specified OS(es).
• OS constants are in org.junit.jupiter.api.condition.OS.

Quick syntax

@EnabledOnOs(OS.WINDOWS)
void windowsOnly() { /* ... */ }

Example

OS-based conditions

package com.logicbig.example;

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;

import static org.junit.jupiter.api.Assertions.assertTrue;

class OsConditionExamplesTest {

    @Test
    @EnabledOnOs(OS.WINDOWS)
    void runs_on_windows_only() {
        assertTrue(true);
    }

    @Test
    @DisabledOnOs(OS.LINUX)
    void not_run_on_linux() {
        assertTrue(true);
    }

    @Test
    void always_runs_control() {
        assertTrue(true);
    }
}

mvn test -Dtest=OsConditionExamplesTest
