Question

I have these two lines in a unit test.
If I comment out the STAssertTrue test, the data gets written to file with no issues and write to file is YES.

BOOL writeResult = [winePDF writeToFile:wineDocumentDirectoryFilename atomically:YES];
STAssertTrue((writeResult), @"Didn't write to file");

I would expect this test to pass, but it fails. I’ve tried

STAssertEquals(YES, writeResult, @"Didn't write to file"); 

which also failed.

Not done much in unit testing so slapping my forehead in anticipation of your well informed answer.

Answer 1

Your code looks correct to me. Are you sure the write is succeeding? Are you sure that winePDF is non-nill?

I would suggest adding this before your first line:

STAssertNotNil(winePDF, @"winePDF should not be nil");
