UITest common assertions for unit tests

xctfail (Format ...) generates a failed test; Xctfail (@"Fail"); Xctassertnil (A1, format ...) for null judgment, A1 is empty when passed, and vice versa; Xctassertnil (@"Not nil string",@"string must be nil"); Xctassertnotnil (A1, Format ...) is not null-judged, A1 is not empty when passed, and vice versa; Xctassertnotnil (@"Not nil string",@"string can not is nil"); Xctassert (expression, format ...) is passed when expression evaluates to true; Xctassert (2>2),@"expression must be true"); Xctasserttrue (expression, format ...) is passed when expression evaluates to true; Xctasserttrue (1,@"Can not is zero"); Xctassertfalse (expression, format ...) is passed when expression evaluates to false; Xctassertfalse (2<2),@"expression must be false"); Xctassertequalobjects (A1, A2, Format ...) is judged equal, [A1 ISEQUAL:A2] value is true when passed, one of which is not empty when not passed; Xctassertequalobjects (@"1",@"1",@"[A1 ISEQUAL:A2] should return YES"); Xctassertequalobjects (@"1",@"2",@"[A1 ISEQUAL:A2] should return YES"); Xctassertnotequalobjects (A1, A2, Format ...), the value of [A1 ISEQUAL:A2] is false when passed, Xctassertnotequalobjects (@"1",@"1",@"[A1 ISEQUAL:A2] should return NO"); Xctassertnotequalobjects (@"1",@"2",@"[A1 ISEQUAL:A2] should return NO"); Xctassertequal (A1, A2, Format ...)

The judgment is equal, (double or float type) provides an error range when in the error range (+/-accuracy) pass the test within equal time; Xctassertequalwithaccuracy (1.0f,1.5f,0.25f,@"A1 = A2 in accuracy should return YES");    Xctassertnotequalwithaccuracy (A1, a2, accuracy, Format ...) The judgment is unequal, (double or float type) provides an error range, which passes the test when the error range is not equal; Xctassertnotequalwithaccuracy (1.0f,1.5f,0.25f,@"A1 = A2 in accuracy should return NO"); Xctassertthrows (expression, format ...) exception test, passed when expression has an exception; (very perverted) xctassertthrowsspecific (expression, Specificexception, Format ...) Exception tests, which pass when expression has an specificexception exception, and other exceptions or exceptions that do not occur; xctassertthrowsspecificnamed (expression, Specificexception, Exception_name, Format ...) Exception test, when expression has a specific exception, the exception of the specific exception name passed the test, and vice versa; Xctassertnothrow (expression, format ...) exception test, passing the test when expression does not occur abnormally; Xctassertnothrowspecific (expression, specificexception, format ...) Exception test, when expression does not have a specific exception, the specific exception name of the exception passed the test, and vice versa; xctassertnothrowspecificnamed (expression, specificexception, Exception_name, Format ...) An exception test that passes the test when expression does not have an exception that has a specific exception, a specific exception name, and vice versa .
