Testing Objective-C class by XCTest with plain old Makefile in command line.

main.m

#import "MyObject.h"

int main()
{
    @autoreleasepool {
        MyObject *myObject = [[MyObject alloc] init];
        NSLog(@"myObject = %@", myObject);
    }
}

Makefile

CLASS_NAME = MyObject
OBJS = main.o $(CLASS_NAME).o $(CLASS_NAME)Tests.o
PROGRAM = a.out

CFLAGS = -Wall -F$(FWPATH)
LIBS = -F$(FWPATH) -framework XCTest -framework Foundation

FWPATH = /Applications/Xcode.app/Contents/Developer/Library/Frameworks
XCTEST = /Applications/Xcode.app/Contents/Developer/usr/bin/xctest

$(PROGRAM): $(OBJS)
	$(CC) -o $(PROGRAM) $(OBJS) $(LIBS)

test: $(PROGRAM)
	DYLD_FRAMEWORK_PATH=$(FWPATH) $(XCTEST) -XCTest $(CLASS_NAME)Tests $(PROGRAM)

clean:
	$(RM) -rf $(PROGRAM) *.o

$(OBJS): $(CLASS_NAME).h

MyObject.h

#import <Foundation/Foundation.h>

@interface MyObject : NSObject

@end

MyObject.m

#import "MyObject.h"

@implementation MyObject

@end

MyObjectTests.m

#import <XCTest/XCTest.h>
#import "MyObject.h"

@interface MyObjectTests : XCTestCase

@end

@implementation MyObjectTests

- (void)setUp
{
    [super setUp];
    // Put setup code here. This method is called before the invocation of each test method in the class.
}

- (void)tearDown
{
    // Put teardown code here. This method is called after the invocation of each test method in the class.
    [super tearDown];
}

- (void)testExample
{
    MyObject *myObject = [[MyObject alloc] init];
    XCTAssert(myObject != nil, @"myObject is successfully created.");
}

@end

Thanks. I was looking for this.

The hardcoded paths can be replaced by:

FWPATH=$(xcode-select --print-path)/Library/Frameworks
XCTEST=$(xcrun --find xctest)

Hello, Could you please explain (for dummies like me), how you run this make file from the Terminal (command line)?
I follow the logic but I can't make it work.

Thank you
