Objc
This gem is a test suite runner for Objective-C files to allow for the easy execution of a test suite without the hassle of managing an Xcode Project File
Installation
Install the gem
$ gem install objc
Install xctool
$ brew install xctool
Usage
$ objc Bob
The objc binary will find and run the tests for the following files: Bob.h,
Bob.m and BobTest.m.
The test suite used is XCTest. This is an example of the header, source and test file.
Bob.h
#import <Foundation/Foundation.h>
@interface Bob : NSObject
- (NSString *)hey:(NSString *)statement;
@end
Bob.m
#import "Bob.h"
@implementation Bob
-(NSString *)hey:(NSString *)statement {
if ([statement isEqualToString:@""]) {
return @"Fine, be that way.";
} else if ([statement hasSuffix:@"?"]) {
return @"Sure.";
} else if ([statement isEqualToString:[statement uppercaseString]]) {
return @"Woah, chill out!";
} else {
return @"Whatever.";
}
}
@end
BobTest.m
#import <XCTest/XCTest.h>
#import "Bob.h"
@interface test_suite : XCTestCase
@end
@implementation test_suite
- (Bob *)bob {
return [[Bob alloc] init];
}
- (void)testStatingSomething {
NSString *input = @"Tom-ay-to, tom-aaaah-to.";
NSString *expected = @"Whatever.";
NSString *result = [[self bob] hey:input];
XCTAssertEqual(expected,result);
}
- (void)testShouting {
NSString *input = @"WATCH OUT!";
NSString *expected = @"Woah, chill out!";
NSString *result = [[self bob] hey:input];
XCTAssertEqual(expected,result);
}
- (void)testAskingAQuestion {
NSString *input = @"Does this cryogenic chamber make me look fat?";
NSString *expected = @"Sure.";
NSString *result = [[self bob] hey:input];
XCTAssertEqual(expected,result);
}
- (void)testTalkingForcefully {
NSString *input = @"Let's go make out behind the gym!";
NSString *expected = @"Whatever.";
NSString *result = [[self bob] hey:input];
XCTAssertEqual(expected,result);
}
- (void)testShoutingNumbers {
NSString *input = @"1, 2, 3 GO!";
NSString *expected = @"Woah, chill out!";
NSString *result = [[self bob] hey:input];
XCTAssertEqual(expected,result);
}
- (void)testShoutingWithSpecialCharacters {
NSString *input = @"ZOMG THE %^*@#$(*^ ZOMBIES ARE COMING!!11!!1!";
NSString *expected = @"Woah, chill out!";
NSString *result = [[self bob] hey:input];
XCTAssertEqual(expected,result);
}
- (void)testSilence {
NSString *input = @"";
NSString *expected = @"Fine, be that way.";
NSString *result = [[self bob] hey:input];
XCTAssertEqual(expected,result);
}
@end
Details
When you run objc Bob, more specifically the following occurs:
- Finds the files matching the specified prefix (e.g.
Bob.h,Bob.mandBobTest.m) - An Xcode Project, managed by the gem, is copied to to a tmp location on the system.
- Using the xcoder the project file is manipulated and the found files are added.
- Using xctool the tests from the project file are executed.
Limitations
- Currently the template project is a Cocoa App that will launch a window for a brief moment during the tets. I couldn't get a project with just tests to run with xctool or xcodebuild.
