无法在 powermock 中使用 @PowerMockIgnore 创建 restTemplate
Fail to restTemplate create with @PowerMockIgnore in powermock
我需要一个用于私有方法测试的 powermock。
如果我只使用 @RunWith(PowerMockRunner.class) 而不使用 @PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)，它运行良好。
我需要为@autowired 使用@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)。
但它不会启动失败。
@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { MyConfig.class})
@SpringBootTest
public class SpringPowerMockTest {
}

因此我通过 https://github.com/powermock/powermock/issues/864
添加了这个
@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { MyConfig.class})
// I added this
@PowerMockIgnore({"javax.net.ssl.*", "org.slf4j.*", "javax.parsers.*", "ch.qos.logback.*",
"jdk.xml.internal.*", "com.sun.org.apache.xerces.*", "javax.xml.*", "org.xml.*",
"javax.management.*"})
@SpringBootTest
public class SpringPowerMockTest {
@Test
public void test() {
//success
}
}
运行良好。
于是，我开始写测试代码
@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { MyConfig.class})
@PowerMockIgnore({"javax.net.ssl.*", "org.slf4j.*", "javax.parsers.*", "ch.qos.logback.*",
"jdk.xml.internal.*", "com.sun.org.apache.xerces.*", "javax.xml.*", "org.xml.*",
"javax.management.*"})
@SpringBootTest
public class SpringPowerMockTest {
@Test
public void initalize() throws IOException {
RestTemplate restTemplate = new RestTemplate();
.....
}
}
但是我无法从这个错误消息开始

不知道为什么不能创建RestTempleate。我不知道@PowerMockIgnore
我通过在行下添加代码解决了这个问题。但是我不明白是什么原因。

Powermocked 目标代码。

我需要一个用于私有方法测试的 powermock。
如果我只使用 @RunWith(PowerMockRunner.class) 而不使用 @PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)，它运行良好。
我需要为@autowired 使用@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)。

因此我通过 https://github.com/powermock/powermock/issues/864
添加了这个@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { MyConfig.class})
// I added this
@PowerMockIgnore({"javax.net.ssl.*", "org.slf4j.*", "javax.parsers.*", "ch.qos.logback.*",

"javax.management.*"})
@SpringBootTest
public class SpringPowerMockTest {
@Test
public void test() {
//success

}
运行良好。
于是，我开始写测试代码
@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { MyConfig.class})
@PowerMockIgnore({"javax.net.ssl.*", "org.slf4j.*", "javax.parsers.*", "ch.qos.logback.*",

@SpringBootTest
public class SpringPowerMockTest {
@Test
public void initalize() throws IOException {

不知道为什么不能创建RestTempleate。我不知道@PowerMockIgnore
我通过在行下添加代码解决了这个问题。但是我不明白是什么原因。
com.sun.org.apache.xalan.internal.xsltc.trax.*
这是 powermock 方法的代码

Powermocked 目标代码。
