  57. <p>1新建一个测试的Target</p>
  58. <p><img src="/images/blog/test-target.png" alt="Test Target" /></p>
  59. <p>2设置Search Paths
  60. 保持和项目的Target设置一致不然在引用文件的时候可能会提示有些文件找不到比如LoginManager.h:10:9: fatal error: &lsquo;biz/service/auth/auth_protocol.h&rsquo; file not found</p>
  61. <p><img src="/images/blog/search-paths.png" alt="Search Paths" /></p>
  62. <p>3新建Test Class</p>
  63. <p>见图一</p>
  64. <p>4引入需要的文件开始测试
  65. 比如要写一个登录的单元测试那要引入LoginManager.h之类的文件吧我大概写一下有些是项目的代码不知道写在博文里面好不好</p>
  66. <pre><code>#import &lt;UIKit/UIKit.h&gt;

  128. <p>5异步测试要点</p>
  129. <pre><code>_expectation = [self expectationWithDescription:@"Login request”];
  130. [_expectation fulfill];
  131. XCTAssert(YES, @"Pass");
  132. </code></pre>
  133. <p>6其他</p>
  134. <p>其他的异步测试比如BlockDelegate的方式也都如此(采用XCTestExpectation)</p>
