如何在Junit测试中覆盖IF语句

Question

我对Juint测试很陌生。我很难涵盖以下方法的所有内容：

private GetMWSAuthTokenByOwnerAndSignatoryResult getMWSAuthToken(SellerUniversalId ownerId, SellerUniversalId signatoryId,boolean isContractAvailable) {
    try {
        String mwsAuthToken = this.mwsClientAdapter.getMWSAuthToken(
                signatoryId.getMarketplaceMerchant().getMerchantId(),
                ownerId.getMarketplaceMerchant().getMerchantId());
        return buildGetMWSAuthTokenByOwnerAndSignatoryResult(mwsAuthToken);
    } catch (MWSAuthTokenDoesNotExistException e) {
        if (isContractAvailable == false) {
            return GetMWSAuthTokenByOwnerAndSignatoryResult.builder().build();
        } else {
            throw new MWSAuthTokenNotFoundException(e);
        }
    }

其他部分的Junit已经在那里了，但是当isContractAvailable == false.时，我无法覆盖If部分。

其他部分的Junit代码是-

@Test(expected = MWSAuthTokenNotFoundException.class)
public void testMwsAuthThrowsTokenNotFoundException() throws StorageException, MWSException, MWSAuthTokenDoesNotExistException {
    mockContract0.withOwnerId(mockOwnerId);
    mockContracts = Arrays.asList(mockContract0.get());
    mockContractStorage.withGetContractsBySignatoryId(mockSellerId, mockState, mockContracts);
    when( mockMwsClientAdapter.getMWSAuthToken(mockSellerMerchantId, mockOwnerMerchantId) )
            .thenThrow(new MWSAuthTokenDoesNotExistException("message"));

    GetMWSAuthTokenByOwnerAndSignatoryActivity activity = new GetMWSAuthTokenByOwnerAndSignatoryActivity(
            mockContext.get(), mockMwsClientAdapter, mockMetricsHelper);
    activity.enact(getActivityInput( mockOwnerId, mockSellerId ));
}

WHat应该是涵盖If部件？的Juint测试用例，我使用的是JUnit-4。

您能找到活动调用要测试的方法的部分吗？它是如何确定isContractAvailable参数的？是生成代码还是自定义代码？

这可能与ContractStorage有关，因此您应该找到一种方法来设置mockContractStorage，以确保isContractAvailable变为假的。

也许是这样：

mockContractStorage.withGetContractsBySignatoryId(mockSellerId, mockState, 
                                                Collections.emptyList());
