在NPE的测试结果中使用PowerMock获得ATG核 [英] Using PowerMock to obtain the ATG Nucleus in testing results in NPE

问题描述

我正在尝试测试以下代码：

I am trying to test the following bit of code:

GSARepository productCatalog = (GSARepository) Nucleus.getGlobalNucleus().resolveName("/atg/commerce/catalog/ProductCatalog");
for (RepositoryItem orderItem : orderItems) {
    String product = (String) orderItem.getPropertyValue(PropertyNameConstants.PRODUCTID);
    if (!ProductUtils.isSpecial(product, productCatalog)) {
        isSpecial = false;
        break;
    }
}

显然Nucleus.getGlobalNucleus（）是静态的。

clearly Nucleus.getGlobalNucleus() is static.

根据文档，我应该可以使用：

According to the docs I should be able to use:

PowerMockito.mockStatic(Nucleus.class);
PowerMockito.when(Nucleus.getGlobalNucleus()).thenReturn(globalNucleusMock);    
PowerMockito.when(globalNucleusMock.resolveName("/atg/commerce/catalog/ProductCatalog");

无论哪种方式，我在调用时仍会得到一个空指针：

Eitherway, I still get a nullpointer when I call:

Nucleus.getGlobalNucleus().resolveName("/atg/commerce/catalog/ProductCatalog")

推荐答案

不要忘记使用JUnit运行器：

Don't forget to use JUnit runner :

@RunWith(PowerMockRunner.class)
@PrepareForTest(Nucleus.class)
public class YourClassTest {
