Collections.sort(employees, new Comparator<Employee>() {

    public int compare(Employee s, Employee s1) {
        int comp = s.getName().compareTo(s1.getName());
        if (comp != 0) {    // names are different
            return comp;
        }
        return s.getSalary() - s1.getSalary();
    }
});
System.out.println(employees);

}

尝试运行 JUnit 测试错误时，测试将无法正确运行

package picocli;

import picocli.CommandLine.Option;

public class ComparatorRunnerConfig {

      @Option(names = {"-rc", "--report-class"}, required = false,
              description = "define report")
      private String report;

      public String getReport() {
            return report;
      }
}

我的 JUnit 测试：

package picocli;

import static org.junit.Assert.*;
import org.junit.Test;

public class ConfigurationTest {

    @Test
    public void testBasicConfigOptions() {
        String args = "-rc BlahBlah";
        ComparatorRunnerConfig mfc = new ComparatorRunnerConfig();
        new CommandLine(mfc).parse(args);

        String myTestValue = mfc.getReport();
        assertEquals(myTestValue, "BlahBlah");
    }
}

测试失败。
