mockito test在运行junit test时没有给出这样的方法错误,但是当在运行配置中手动添加jar时,它运行良好

Question

我一直面临着一个特殊的问题.基本上,当我正常运行我的Mockito/PowerMockito测试,即'Run as Junit Test'时,它会给我以下错误:

我曾尝试在maven依赖项和构建路径中添加所有必需的jar,但无济于事.

但是,我随后在运行配置 - >类路径 - >用户条目中手动添加了jar.然后,我像往常一样运行测试,它显示绿色状态栏,即它运行完美.

请帮帮我.我需要在没有这些令人讨厌的变化的情况下进行测试,这会影响我的工作.我能做什么才能让我通常运行测试,即不用一直运行配置,只需在构建路径中添加jar然后"运行为junit test"？

Answer 1

在你的eclipse屏幕上尝试Cntrl + Shift + T. 检查你的结果是什么.理想情况下,eclipse只能从一个依赖项中解析此类.如果您获得多个结果,则可能需要在某些依赖项上添加排除项.

还要检查是否能够从命令提示符执行测试用例.如果你能够做到这一点,那么这不是一个maven问题.但如果此处出现问题,请检查您的依赖项.

Answer 2

对我来说,mockito版本正在创造问题.如果您已在pom文件中明确添加,请删除mockito依赖项.我刚刚删除 -

testCompile 'org.mockito:mockito-all:1.9.5' 

我的gradle文件中的行.让权力模拟解决并添加它自己需要的mockito依赖,而不是你强行添加一个可能导致冲突.

所以对我来说依赖是 -

testCompile "org.powermock:powermock-module-junit4:1.6.4"
testCompile "org.powermock:powermock-module-junit4-rule:1.6.4" 
testCompile "org.powermock:powermock-api-mockito:1.6.4" 
testCompile "org.powermock:powermock-classloading-xstream:1.6.4" 

除了junit和其他lib依赖项之外你可能有.

其他答案给了我指导，但真正引发我问题的是我不小心导入了

import static org.mockito.ArgumentMatchers.eq;

当其余代码使用

import static org.mockito.Matchers.any;

你问有什么问题吗？

嗯，org.mockito.ArgumentMatchers是从 Mockito 2.23 中获取的，并且org.mockito.Matchers（以及其余的mockito 导入）是从 Mockito 1.9 中导入的。

在版本 2.23Matchers类中extends ArgumentMatchers（因此静态匹配器不再存在，它们在ArgumentMatchers类中）并标记为@Deprecated

无论如何，这触发了java.lang.NoSuchMethodError消息，解决方案是坚持使用 1.9 版本，然后简单地使用

import static org.mockito.Matchers.eq;
