Question

我正在与fitnesse（20140630）+ maven

合作

但是当我运行测试时，我会遇到异常：

异常：显示java.lang.NullPointerException 在com.playtech.openapi.core.fitnesse.tests.Fixtures.createContext（Fixtures.java:14）[file：/ D：/FitnesseTests/IntegrationTestsMobileAdmin/com-playtech-openapi-frontend-services/com.playtech.openapi。 core.fitnesse.tests /目标/类/] at sun.reflect.NativeMethodAccessorImpl.invoke0（Native Method）[rt.jar：1.7.0_21] at sun.reflect.NativeMethodAccessorImpl.invoke（NativeMethodAccessorImpl.java:57）[rt.jar：1.7.0_21] at sun.reflect.DelegatingMethodAccessorImpl.invoke（DelegatingMethodAccessorImpl.java:43）[rt.jar：1.7.0_21] 在java.lang.reflect.Method.invoke（Method.java:601）[rt.jar：1.7.0_21] at fitnesse.slim.fixtureInteraction.DefaultInteraction.methodInvoke（DefaultInteraction.java:16）[fitnesse-standalone.jar] at fitnesse.slim.MethodExecutor.callMethod（MethodExecutor.java:43）[fitnesse-standalone.jar] at fitnesse.slim.MethodExecutor.invokeMethod（MethodExecutor.java:30）[fitnesse-standalone.jar] at fitnesse.slim.MethodExecutor.findAndInvoke（MethodExecutor.java:52）[fitnesse-standalone.jar] at fitnesse.slim.FixtureMethodExecutor.execute（FixtureMethodExecutor.java:20）[fitnesse-standalone.jar] at fitnesse.slim.StatementExecutor.getMethodExecutionResult（StatementExecutor.java:121)[fitnesse-standalone.jar] at fitnesse.slim.StatementExecutor.callAndAssign（StatementExecutor.java:109）[fitnesse-standalone.jar] at fitnesse.slim.instructions.CallAndAssignInstruction.executeInternal（CallAndAssignInstruction.java:38）[fitnesse-standalone.jar] at fitnesse.slim.instructions.Instruction.execute（Instruction.java:30）[fitnesse-standalone.jar] at fitnesse.slim.ListExecutor $ Executive.executeStatement（ListExecutor.java:50）[fitnesse-standalone.jar] at fitnesse.slim.ListExecutor $ Executive.executeStatements（ListExecutor.java:44）[fitnesse-standalone.jar] at fitnesse.slim.ListExecutor.execute（ListExecutor.java:84）[fitnesse-standalone.jar] at fitnesse.slim.SlimServer.executeInstructions（SlimServer.java:107）[fitnesse-standalone.jar] at fitnesse.slim.SlimServer.processTheInstructions（SlimServer.java:94）[fitnesse-standalone.jar] at fitnesse.slim.SlimServer.processOneSetOfInstructions（SlimServer.java:68）[fitnesse-standalone.jar] at fitnesse.slim.SlimServer.tryProcessInstructions（SlimServer.java:54）[fitnesse-standalone.jar] at fitnesse.slim.SlimServer.serve（SlimServer.java:40）[fitnesse-standalone.jar] at fitnesse.slim.SlimService.handle（SlimService.java:164）[fitnesse-standalone.jar] at fitnesse.slim.SlimService.acceptOne（SlimService.java:172）[fitnesse-standalone.jar] at fitnesse.slim.SlimService.accept（SlimService.java:134）[fitnesse-standalone.jar] at fitnesse.slim.SlimService.startWithFactory（SlimService.java:65）[fitnesse-standalone.jar] at fitnesse.slim.SlimService.main（SlimService.java:51）[fitnesse-standalone.jar]

这是我的Java代码

public class Tests extends AbstractClientIT {

    public String createContext(){
        return "1234567";
    }
}


public class Fixtures {

    private Tests service2;


    public String createContext () throws RemoteException {
        return service2.createContext();
    }

}

Answer 1

public String createContext () throws RemoteException {
    return service2.createContext();
}

service2尚未初始化，因此这是您的NPE

Answer 2

我是FitNesse的新手，但今天我刚刚在FitNesse＆＃34;＆＃34;测试驱动的.NET开发中找到了这个段落。第24页的书：

如果您创建了一个页面（或尝试创建一个页面）并且出现NullPointerException错误，或者该页面没有出现，则您选择了错误的名称。 FitNesse仅将CamelCase单词视为有效的页面名称，并对此严格。页面名称必须以大写字母开头，并且至少包含一个大写字母。还有一个值得注意的问题：连续大写字母。 FitNesse不喜欢他们。因此页面名称中的大写字母必须至少用一个小写字母分隔。这个惯例给FitNesse新手带来了很多麻烦，但过了一段时间你就会习惯它。
