Question

我不知道发生了什么，因为我对目标c和IOS开发相当新。

当我尝试运行我的测试时，使用默认测试框架我收到以下错误：

        ..../Pods/Expecta/src/matchers/EXPMatchers+beCloseTo.m:4:1: 
Class 'EXPFixCategoriesBugEXPMatcher_beCloseToWithinMatcher' 
    defined without specifying a base class

下面的代码会产生问题（不过它不是我的，我相信它是我通过pod使用的其中一个库的一个peice）：

#import "EXPMatchers+beCloseTo.h"
#import "EXPMatcherHelpers.h"

EXPMatcherImplementationBegin(_beCloseToWithin, (id expected, id within)) {
  prerequisite(^BOOL{
    return [actual isKindOfClass:[NSNumber class]] &&
        [expected isKindOfClass:[NSNumber class]] &&
        ([within isKindOfClass:[NSNumber class]] || (within == nil));
  });

  match(^BOOL{
        double actualValue = [actual doubleValue];
        double expectedValue = [expected doubleValue];

        if (within != nil) {
            double withinValue = [within doubleValue];
            double lowerBound = expectedValue - withinValue;
            double upperBound = expectedValue + withinValue;
            return (actualValue >= lowerBound) && (actualValue <= upperBound);
        } else {
            double diff = fabs(actualValue - expectedValue);
            actualValue = fabs(actualValue);
            expectedValue = fabs(expectedValue);
            double largest = (expectedValue > actualValue) ? expectedValue : actualValue;
            return (diff <= largest * FLT_EPSILON);
        }
  });

  failureMessageForTo(^NSString *{
    if (within) {
      return [NSString stringWithFormat:@"expected %@ to be close to %@ within %@",
              EXPDescribeObject(actual), EXPDescribeObject(expected), EXPDescribeObject(within)];
    } else {
      return [NSString stringWithFormat:@"expected %@ to be close to %@",
              EXPDescribeObject(actual), EXPDescribeObject(expected)];
    }
  });

  failureMessageForNotTo(^NSString *{
    if (within) {
      return [NSString stringWithFormat:@"expected %@ not to be close to %@ within %@",
              EXPDescribeObject(actual), EXPDescribeObject(expected), EXPDescribeObject(within)];
    } else {
      return [NSString stringWithFormat:@"expected %@ not to be close to %@",
              EXPDescribeObject(actual), EXPDescribeObject(expected)];
    }
  });
}
EXPMatcherImplementationEnd

我的POD文件如下所示：

platform :ios, 6.0
pod 'RestKit', '~> 0.20.0rc'

# Include optional Testing and Search components
pod 'RestKit/Testing', '~> 0.20.0rc'
pod 'RestKit/Search', '~> 0.20.0rc'


target :MTPROJTESTS do
  pod 'Expecta',     '~> 0.2.3'   # expecta matchers
  # pod 'Specta',      '~> 0.1.11'  # specta bdd framework
end

更新可可豆荚和EXPECTA后的新错误：ld: library not found for -lPods-test clang: error: linker command failed with exit code 1 (use -v to see invocation)

错误：

我希望那里的人有一个线索：）

关于新的链接器错误：Xcode喜欢为测试添加新的构建目标，因此请确保将所有相应的文件（例如，.m源文件，静态库，框架）设置为包含在测试构建目标。您可以通过在Project Navigator中选择文件并查看File Inspector窗格中的“Target Membership”部分来完成此操作;确保选中该框用于测试构建目标。此外，在项目设置中，您可以选择测试构建目标并转到构建阶段并查看“使用库链接二进制”以确保链接相应的库。

听起来EXPFixCategoriesBugEXPMatcher_beCloseToWithinMatcher的基类位于应用项目的前缀标题中，但未在EXPFixCategoriesBugEXPMatcher_beCloseToWithinMatcher的.h文件中导入。通常应该在类的接口文件顶部导入基类：

#import "YourBaseClassHere.h"

@interface EXPFixCategoriesBugEXPMatcher_beCloseToWithinMatcher : YourBaseClassHere

// The rest of your class here

@end

目标C运行测试时：定义类而不指定基类
