Exception when I run a test twice #678

Closed dtaitz closed 8 years ago

dtaitz commented 8 years ago

Hello,

I recently switched over to Kiwi. I wrote a few specs can successfully run my tests right after I open up my workspace in Xcode. Yet, if I try to run the test again without exiting and reopening my workspace, I get the following error. Please advise

* Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[NSInvocation _invocationWithMethodSignature:frame:]: method signature argument cannot be nil' * First throw call stack: ( 0 CoreFoundation 0x0000000106020d85 __exceptionPreprocess + 165 1 libobjc.A.dylib 0x00000001056b9deb objc_exception_throw + 48 2 CoreFoundation 0x0000000105ee071d +[NSInvocation _invocationWithMethodSignature:frame:] + 333 3 XCTest 0x00000001055c3ea9 -[XCTestCase initWithSelector:] + 167 4 XCTest 0x00000001055c3f08 +[XCTestCase testCaseWithSelector:] + 43 5 XCTest 0x00000001055c24cb +[XCTestSuite testSuiteForTestCaseWithName:] + 344 6 XCTest 0x00000001055c3181 -[XCTestSuite _initWithTestConfiguration:] + 508 7 XCTest 0x00000001055c3674 +[XCTestSuite testSuiteForTestConfiguration:] + 50 8 XCTest 0x00000001055af979 -[XCTestDriver _runSuite] + 233 9 XCTest 0x00000001055b07d1 -[XCTestDriver _checkForTestManager] + 259 10 XCTest 0x00000001055faa9a _XCTestMain + 628 11 CoreFoundation 0x0000000105f462ec CFRUNLOOP_IS_CALLING_OUT_TO_A_BLOCK + 12 12 CoreFoundation 0x0000000105f3bf75 CFRunLoopDoBlocks + 341 13 CoreFoundation 0x0000000105f3b6d2 CFRunLoopRun + 850 14 CoreFoundation 0x0000000105f3b0f8 CFRunLoopRunSpecific + 488 15 GraphicsServices 0x0000000108e0aad2 GSEventRunModal + 161 16 UIKit 0x0000000103d52f09 UIApplicationMain + 171 17 Planvan 0x000000010087ccd4 main + 180 18 libdyld.dylib 0x00000001068e992d start + 1 ) libc++abi.dylib: terminating with uncaught exception of type NSException (lldb)

Same to me, but my colleague who use the same code on his computer have no problem.

Hey! Sorry for this. Based on your stack trace, which includes +[XCTestCase testCaseWithSelector:], I assume you're running an individual test? Kiwi has never been very good at supporting individual tests... we only really support running all tests (⌘+U).

The best way to help test frameworks like Kiwi to support this would be to file an Apple Radar. Please copy and paste the text from https://openradar.appspot.com/26028557 and submit that to Apple.

In the meantime, I'll close this issue (@sharplet and I are trying to do some spring cleaning). Please re-open this issue or create another one if you're encountering this problem when running all tests.

This is the single biggest reason we're considering abandoning Kiwi. Being able to quickly iterate and debug a single test is difficult at best using this framework, let alone having to restart XCode every so often.

I use Xcode schemes, and focus tests to get that kind of behaviour (with Specta/Quick but they all have the same problems )
