Question

我遇到了这样的AssertionError：

java.lang.AssertionError: 
  Unexpected method call ICustomerDAO.getVersionStamps(-1, ["CustomerData", "UserData"], EasyMock for interface java.sql.Connection):
    ICustomerDAO.getVersionStamps(-1, ["CustomerData", "UserData"], EasyMock for interface java.sql.Connection): expected: 1, actual: 0
    at org.easymock.internal.MockInvocationHandler.invoke(MockInvocationHandler.java:44)
    at org.easymock.internal.ObjectMethodsFilter.invoke(ObjectMethodsFilter.java:94)
    at com.sun.proxy.$Proxy3.getVersionStamps(Unknown Source)
    at com.mgmt.ConfigClient.getRequestedVersions(ConfigClient.java:200)
    at com.mgmt.ConfigClientTest.testGetRequestedVersions(ConfigClientTest.java:329)

这是测试代码：

@Test
public void testGetRequestedVersions() {
    ConfigClient client = new ConfigClient();
    client.dao = EasyMock.createStrictMock(ICustomerDAO.class);
    Connection connection = EasyMock.createStrictMock(Connection.class);
    long[] versions = {34, 12};
    EasyMock.expect(client.dao.getVersionStamps(-1, ConfigFilesRegenTask.getRequestedVersions(), connection)).andReturn(versions);
    EasyMock.replay(client.dao);
    ConfigToken token = client.getRequestedVersions(connection);
    EasyMock.verify(client.dao);
    assertEquals("Wrong customer version", versions[0], token.getCustomerVersion());
}

ConfigClient类：

public ConfigToken getRequestedVersions(Connection connection) {
    final ConfigToken token = new ConfigToken(-1, -1);
    long[] requestedVersions = dao.getVersionStamps( -1, ConfigFilesRegenTask.getRequestedVersions(), connection);
    token.setCustomerVersion(requestedVersions[0]);
    return token;
}

ConfigFilesRegenTask类包含get方法，该方法返回现有数组的克隆：

public static String[] getRequestedVersions() {
    return REQUESTED_VERSIONS.clone();
}

仅当我返回数组的REQUESTED_VERSIONS克隆时才会发生断言错误。 我怎么能绕过这个？

有点难以理解你的例子，但我最好的猜测是你需要使用Array Equality argument matcher而不是默认的匹配器来检查.equals（），这对于阵列。

尝试将您的期望改为：

EasyMock.expect(client.dao.getVersionStamps(eq(-1), aryEq(ConfigFilesRegenTask.getRequestedVersions()), eq(connection))).andReturn(versions);

EasyMock：将对象与其克隆进行比较时的AssertionError
