如何添加一个不从TestCase扩展到TestSuite的JUnit 4测试？

Question

在JUnit 3中,我只是打电话给

suite.addTestSuite( MyTest.class )

但是,如果MyTest是一个不扩展TestCase的JUnit 4测试,则不起作用.我应该怎么做才能创建一套测试？

Answer 1

自己找到了答案:这里

像这样:

import org.junit.runner.RunWith;
import org.junit.runners.Suite;

@RunWith(Suite.class)
@Suite.SuiteClasses({
  TestCalculatorAddition.class,
  TestCalculatorSubtraction.class,
  TestCalculatorMultiplication.class,
  TestCalculatorDivision.class
})
public class CalculatorSuite {
    // the class remains completely empty, 
    // being used only as a holder for the above annotations
}

Answer 2

对于需要与新v4样式共存的大型3.8样式套件/测试的用户,您可以执行以下操作:

import org.junit.runner.RunWith;
import org.junit.runners.Suite;

@RunWith(Suite.class)
@Suite.SuiteClasses({
  // Add a JUnit 3 suite
  CalculatorSuite.class,
  // JUnit 4 style tests
  TestCalculatorAddition.class,
  TestCalculatorDivision.class
})
public class CalculatorSuite {
    // A traditional JUnit 3 suite
    public static Test suite() {
        TestSuite suite = new TestSuite();
        suite.addTestSuite(TestCalculatorSubtraction.class);
        return suite;
    }
}
