パスワードの確認には正規表現を使用しています。しかし、意図したとおりに機能していません。正規表現をチェックするためにいくつかのユニットテストを使用します。
@implementation NSString (regexMatch)
- (BOOL)matchesRegex:(NSString *)regexPattern
{
NSError *error = nil;
NSRegularExpression* regex = [NSRegularExpression
regularExpressionWithPattern:regexPattern
options:NSRegularExpressionSearch
error:&error];
if(error)
{
NSLog(@"Error on maches regex: %@ on %@: %@", regex, self, error);
return NO;
}
NSUInteger maches = [regex numberOfMatchesInString:self
options:NSRegularExpressionSearch
range:NSMakeRange(0, [self length])];
return (maches > 0);
}
@end
正規表現:
const static NSString *REGEX_VALID_PASS = @"(^((?=.*\\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[-_,.@#$%'\"]).{6,20})$)";
ユニットテスト:
//Password
// At least:
// - between 6 and 20 chars
// - a capital character
// - a small character
// - a digit
// - a special char: - _ , . @ # $ % ´ '
STAssertTrue([@"Pass1-" matchesRegex:REGEX_VALID_PASS], @"Password 1 failed");
STAssertTrue([@"aPrettyLongPassw0rd@" matchesRegex:REGEX_VALID_PASS], @"Password 2 failed");
STAssertTrue([@"Pw987321-_,.@#$%'`" matchesRegex:REGEX_VALID_PASS], @"Password 3 failed");
//Returns TRUE ???
STAssertFalse([@"password1@" matchesRegex:REGEX_VALID_PASS], @"Wrong password 4 works (No capital letter)");
//Returns TRUE ???
STAssertFalse([@"PASSWORD2#" matchesRegex:REGEX_VALID_PASS], @"Wrong password 5 works (No small letter)");
STAssertFalse([@"Password8" matchesRegex:REGEX_VALID_PASS], @"Wrong password 6 works (No special letter)");
STAssertFalse([@"Password$" matchesRegex:REGEX_VALID_PASS], @"Wrong password 7 works (No digit letter)");
STAssertFalse([@"PrettyLongPasswordIsWrong123#" matchesRegex:REGEX_VALID_PASS], @"Wrong password 8 works (> 20)");
STAssertFalse([@"Pw@3" matchesRegex:REGEX_VALID_PASS], @"Wrong password 9 works (< 6)");
パスワード「password1@」および「PASSWORD2#」はTRUEを返しますが、正しくありません。
エラー:
file://localhost/Users/user/app/AppTest.m: error: testRegex (AppTest) failed: "[@"password1@" matchesRegex:REGEX_VALID_PASS]" should be false. Wrong password 4 works (No capital letter)
and
file://localhost/Users/user/app/AppTest.m: error: testRegex (AppTest) failed: "[@"PASSWORD2#" matchesRegex:REGEX_VALID_PASS]" should be false. Wrong password 5 works (No small letter)
