ios自动化WebDriverAgent测试报错

解决方法:

修改 WebDriverAgentLib/Utilities/FBFailureProofTestCase.m  第26行

self.internalImplementation = (_XCTestCaseImplementation *)[FBXCTestCaseImplementationFailureHoldingProxy proxyWithXCTestCaseImplementation:self.internalImplementation];

修改后

  if ([self respondsToSelector:@selector(internalImplementation)]) {
    // The `internalImplementation` API has been removed since Xcode 11.4
    self.internalImplementation =
      (_XCTestCaseImplementation *)[FBXCTestCaseImplementationFailureHoldingProxy
                                    proxyWithXCTestCaseImplementation:self.internalImplementation];
  } else {
    self.shouldHaltWhenReceivesControl = NO;
  }
}
