Question

我正在尝试使用TestNG运行给定here的EasyMock示例，并且面临一个奇怪的问题。前两个测试运行正常但第三个测试（getPriceDataAccessThrowsRuntimeException）如果单独运行则成功运行。但是，当我用其他两个测试单独或全部一起运行时，第三次测试失败，我得到以下内容：

FAILED: getPriceDataAccessThrowsRuntimeException
org.testng.TestException: 
Expected exception java.lang.RuntimeException but got org.testng.TestException: 
Expected exception java.lang.RuntimeException but got java.lang.AssertionError: 
  Unexpected method call DataAccess.getPriceBySku("3283947"):

以下是测试代码：

@Test
public void getPrice() throws Exception {
    // Set expectations on mocks.
    expect(mockedDependency.getPriceBySku(SKU)).andReturn(new BigDecimal(100));

    // Set mocks into testing mode.
    replay(mockedDependency);
    final BigDecimal price = systemUnderTest.getPrice(SKU);
    assertNotNull(price);

    // Verify behavior.
    verify(mockedDependency);
}

@Test(expectedExceptions = MyCustomException.class)
public void getPriceNonExistentSkuThrowsException() throws Exception {

    // Set expectations on mocks.
    expect(mockedDependency.getPriceBySku(BAD_SKU)).andReturn(null);

    // Set mocks into testing mode.
    replay(mockedDependency);
    final BigDecimal price = systemUnderTest.getPrice(BAD_SKU);
}

@Test(expectedExceptions = RuntimeException.class)
public void getPriceDataAccessThrowsRuntimeException() throws Exception {

    // Set expectations on mocks.
    expect(mockedDependency.getPriceBySku(SKU)).andThrow(new RuntimeException("Fatal data access exception."));

    // Set mocks into testing mode.
    replay(mockedDependency);
    final BigDecimal price = systemUnderTest.getPrice(SKU);
}

任何想法的人，我做错了什么？

从JUnit转换为TestNG时，您似乎犯了一个错误。在linked example中，doBeforeEachTestCase方法在每个测试用例之前运行，这会将模拟的依赖项重置为其基本状态。您尚未包含所有代码：您应该doBeforeEachTestCase annotated与BeforeMethod一起运行TestNG。

EasyMock问题使用addThrow来预期异常
