How did we do? We’d love to know your thoughts on this year’s conference. Take the survey here
I have an old Xcode project that I am adding tests to, and at a high level I see the code coverage percent (the 2.2% number). However, in the detail view, code coverage only shows on the testing bundle, not in the main app bundle.
Anyone have any tips on how to fix this?
A few things to check:
There could always be a bug here, but investigating it might require access to the project.
Yeah the tests call into the application code and all the tests pass. And I verified the settings have code coverage on.
The issue is that the project is so old, I feel like something is conflicting in the settings? I was very confused by the different settings that seem to affect code coverage (the scheme settings both when using test plans and when not, CLANG_ENABLE_CODE_COVERAGE, GCC_GENERATE_TEST_COVERAGE_FILES etc)
But I hear you, it might just too complex to debug in the abstract. I was hoping there would be an easy solution, cause the tests do run, and I am seeing 'number go up' as I add tests. I just don't have access to file-based coverage. It seems to be just overall coverage stats (based on the image in the post).
Just wanted to come back here in case my solution helps others.
As I mentioned, the project in question is very old (prob 10 years at this point). I have updated it over the years, but....yeah.
To start I created a brand new Xcode project with Xcode 16.3. Then I opened my old project and the new project, showing the build settings in 'Levels' view, so I could see each setting and where it is modified. I meticulously went thru each setting comparing my old project to the new project and changed my old project to match the new project (where it made sense, for example, I can't use script sandboxing).
After going thru this process. My coverage works!!!!!
I am not 100% exactly which setting it was, but I noticed that several of setting differences were quite suspicious. Stuff like the C/C++ language dialects being different? The 'Active Compilation Conditions', 'Compilation Mode' and 'Optimization Level'....all were different.
As I said, not sure which setting it was exactly. But to anyone having issues. I recommend this as a process. Just got to buckle down and go setting by setting till you find the magic one!
