Question

我创建了一个视图控制器viewsampleViewController ..它有两个方法setname和getname ..我为该视图控制器创建一个测试用例.我的testcase名称是newTestCase,方法名称是testName.

#import "newTestCase.h"
#import "viewsampleViewController.h"


@implementation newTestCase

在我的testName方法中,

-(void)testName{

 NSString *b=@"hello";
 v =[[viewsampleViewController alloc] init];
 STAssertNotNil(v,@"v doesnt created");
 [v setuname:@"hello"];
 NSString *a=[v getuname];

 STAssertEquals(b,a,@"error:name not equal");
 [v release];

}

-(void)setUp{
 v=[viewsampleViewController alloc];
}

-(void) tearDown{
 [v release];
}

当我建立我有一个错误

请帮助我,

Answer 1

由于体系结构和依赖性而出现此链接器问题.实际上,当我们从其他一些源向项目添加一些文件时,可能无法建立确切的依赖关系.所以编译器生成链接器错误.我通过以下步骤解决了这个问题:

1. 选择目标
2. 选择构建阶段
3. 选择编译源
4. 选择+图标
5. 选择您收到错误的.m文件并添加它.
6. 清理构建并再次运行.

Answer 2

这是一个链接器错误,将viewsampleViewController.m添加到您的测试目标.请将您的类名称大写,使所有内容更具可读性
