AEM 模拟单元测试问题

Question

因为我是Mockito和AEM模型Java的新手。我浏览了一些文档，并为AEM模型Java编写了我的第一个Mockito文件。在我的代码中，我没有看到任何错误，但是在运行时我没有成功，无法 100% 完成代码覆盖率。任何人都可以纠正/帮助我修复我的代码[给定带有相应模拟文件的示例 java]

爪哇文件：

resource = request.getResource();
final ValueMap configurationOptionProperties = resource.getValueMap();
log.debug("iconfigurationOptionProperties is " + configurationOptionProperties);
String count = configurationOptionProperties.get("count", String.class);
if (count != null) {
for (int i = 1; i <= Integer.valueOf(count); i++) {
Accordion accordion = new Accordion();
String title = configurationOptionProperties.get("title" + i, String.class);
String rte = configurationOptionProperties.get("rte" + i, String.class);
accordion.setTitle(title);
accordion.setRte(rte);
accordionList.add(accordion);
}
}
log.info("AccordionModel init method End");
}
public List < Accordion > getAccordionList() {
return accordionList;
}
}

Answer 1

java.lang.AssertionError: expected:<[]> but was:<null>

如果您返回null您的列表为空。所以调整你的测试。 还要考虑重命名方法名称。 如果这不是您想要的，则需要更改实现。

@Test
public void shouldReturnNullWhenPropertyIsNull() throws LoginException, JSONException {
when(valuemap.get("count", String.class)).thenReturn(null);
accordionModel.init();
assertTrue(accordionModel.getAccordionList().isEmpty());
}

java.lang.NumberFormatException: For input string: "count"

"count"不能转换成Integer。尝试改用count变量 ("6"(。

您应该检查列表的内容，现在我对其进行了调整以检查列表的大小是否正确。

@Test
public void shouldReturnWhenPropertyNotNull() throws LoginException, JSONException {
when(valuemap.get("count", String.class)).thenReturn(count);
accordionModel.init();
assertEquals(Integer.valueOf(count), accordionModel.getAccordionList().size());
}

请注意，通常断言的参数顺序应该是expectedvsactual。
