初始化錯誤無法調用Gradle構建中的合同測試

Question

我有我的合同和測試成功生成在我的生成文件夾。生成的測試擴展了我在Gradle構建文件中配置的基類映射。當我運行我的gradle build時，我總是得到錯誤。

請注意，我可以在Intellij中運行單個測試並通過測試。

org.online.project.contracts.FirstContractTest > initializationError FAILED 
java.lang.Exception 

org.online.project.contracts.SecondContractTest > initializationError FAILED 
java.lang.Exception 

這是完整的堆棧跟蹤在測試結果中

java.lang.Exception: No runnable methods

我已經配置我的gradle這個如下圖所示

contracts { 
targetFramework = 'JUNIT' 
testMode = 'MockMvc' 
contractsDslDir = project.file("${project.rootDir}/module/src/test/resources/contracts") 
baseClassMappings { 
    baseClassMapping('.*FirstContract.*', 'org.online.project.contracts.FirstContractTest') 
    baseClassMapping('.*SecondContract.*': 'org.online.project.contracts.SecondContractTest') 
    } 
} 

Answer 1

這裏的問題junit試圖運行我作爲測試助手試圖將測試與模式*Test匹配的基類。通過聲明我的測試類爲abstract解決了我的問題。

public abstract class FirstContractTest { 
    //.... 
}
