尝试使用 PowerMock 和 EasyMock 模拟静态方法时出现 ClassNotFoundException

ClassNotFoundException when try to mock static method with PowerMock and EasyMock

我尝试使用 EasyMock 编写测试,因为我想模拟一个静态方法,所以我想使用 PowerMock。当我想 运行 测试时,我得到一个 ClassNotFoundException。

这是我写的测试:

 @Test
public void whenCreate_ThenCurrentAccountShouldBeFound() throws Exception {
    Account oldAccount = new Account();
    oldAccount.setUsername("Test");
    oldAccount.setFirstName("FirstName");
    oldAccount.setLastName("LastName");
    oldAccount.setPassword("Password");
    oldAccount.setEmail("maxmusteg@hs-pforzheim.de");

    PowerMock.mockStatic(AuthenticationService.class);
    PowerMock.expectNew(de.hspf.nxtgenmondial.backend.service.AuthenticationService.getCurrentlyLoggedInUser()).andReturn(oldAccount);
    replayAll();

    assertEquals("Username name should be Test", "Test", accountService.getCurrentAccount().getUsername());
}

这是静态方法:

public static String getCurrentlyLoggedInUser() {
    if (SecurityContextHolder.getContext().getAuthentication() != null && SecurityContextHolder.getContext().getAuthentication().getPrincipal() != null) {

        if (SecurityContextHolder.getContext().getAuthentication().getPrincipal() instanceof ExtendedUserDetails)
            return ((ExtendedUserDetails) SecurityContextHolder.getContext().getAuthentication().getPrincipal()).getUsername();
        else
            return ((UserDetails) SecurityContextHolder.getContext().getAuthentication().getPrincipal()).getUsername();
    } else
        throw new IllegalStateException("No user logged in");
}

然后是 getCurrentAccount 方法:

public Account getCurrentAccount() {
    Optional<Account> optionalAccount = accountRepository.findOneByEmail(AuthenticationService.getCurrentlyLoggedInUser());
    if (optionalAccount.isPresent())
        return optionalAccount.get();
    else {
        log.warn("Logged in account not found in database");
        return null;
    }
}

这是出现的错误消息。第 105 行是调用 PowerMock.mockStatic() 的地方:

您使用的 PowerMock 版本与您的 EasyMock 版本不兼容。据我所知,是PowerMock太老了。
