What are your environment variables?

Try to run with -v:d and share with me the trace so that I can compare with a Windows machine.

[hmijail]

I ran it with -v:d :

$ dotnet test -v:d Source/IntegrationTests --filter DisplayName~DafnyTests/TestAttribute.dfy | gistit
[xUnit.net 00:00:06.09]     DafnyTests/TestAttribute.dfy [FAIL]
Test Run Failed.
Gist URL: https://gist.github.com/ac5e99cf29512327f824c1872dd2e53a

Not sure if that answers your question about environment variables. If not, please let me know which ones you're interested in; a whole dump would probably include things that shouldn't be public.

[hmijail]

Just in case, I just upgraded to Dafny's latest commit (1fc7bff) and repeated the test:

$ dotnet test -v:d Source/IntegrationTests --filter DisplayName~DafnyTests/TestAttribute.dfy | gistit
[xUnit.net 00:00:04.33]     DafnyTests/TestAttribute.dfy [FAIL]
Test Run Failed.
Gist URL: https://gist.github.com/8f2396fdf66c0cc2cba82c2fda40e536

[robin-aws]

FYI, potentially related to #1540 - the same test was stubbornly failing on Windows until @MikaelMayer figured out an environment variable wasn't being passed through when this test invoked dotnet test itself. There could be something similar going on here even though you're on macOS.

[hmijail]

The thing is, my environment is over 200K, and contains things like access tokens, so I can't just publish it all. And sanitizing all of that would be difficult and uncertain. Is there any subset that is of interest? Is it helpful if I clear most of the environment and repeat the test?

[MikaelMayer]

On Wednesday I just fixed a bug of the same test failing on Windows.
I had to add -v:diag (this is a very long diagnostic process) and found out that an exception was thrown, and with this level of detail I also had access to the precise stack track of the exception being thrown. It turned out, it was part of the NuGET package manager environment and it was missing the environment variable LOCALAPPDATA which we had to pass through. The trace helped me to identify where null was dereferenced and figure out this missing environment variable. Let us know if this helps.

[hmijail]

There's no LOCALAPPDATA in my environment.
In case it helps, I removed the environment variables that looked to me most suspicious security-wise and ran again the test with -v:diag instead of the previously mentioned -v:d. The resulting log is 98MB; it's too big for a gist so I'm attaching it here.
diag2.txt.zip

[hmijail]

Interestingly, though there is no LOCALAPPDATA (with any case) in my environment, I see that the log does mention a LocalAppData. No idea when it appears nor where it comes from.

[MikaelMayer]

I looked at your trace and just figured out I forgot to mention something.
Instead of putting the diagnostics in the command dotnet test -v:n Source/IntegrationTests --filter DisplayName~DafnyTests/TestAttribute.dfy
because this test is actually spawning another test, please insert just before the line // RUN: dotnet test -v:q -noLogo %S 2> %t.testresults.raw || true
the line:
// RUN: dotnet test -v:diag -noLogo %S
There, you should see more clearly the error made by this test.

[hmijail]

I upgraded to Dafny commit 6f23068, modified TestAttribute.dfy as requested and ran again:

$ dotnet test -v:n Source/IntegrationTests --filter DisplayName~DafnyTests/TestAttribute.dfy > log.txt 
[xUnit.net 00:00:04.93]     DafnyTests/TestAttribute.dfy [FAIL]
Test Run Failed.

log.txt.zip

[MikaelMayer]

Can you remove the temporary files in /Output (like Output/DafnyMain.cs) and start again?

[hmijail]

I see a lot of Output directories, none at the root of the Dafny directory. Which one do you mean? Is it enough if I do something like make clean && dotnet test -v:n Source/IntegrationTests --filter DisplayName~DafnyTests/TestAttribute.dfy > log.txt ?

[hmijail]

(I see that make clean still leaves Output directories with files inside, which sounds problematic - by the way, this might be related: #1584 )

Anyway, I guess that you mean (repo root)/Test/DafnyTests/Output, which does contain a DafnyMain.cs. I deleted that directory and reran.

$ dotnet test -v:n Source/IntegrationTests --filter DisplayName~DafnyTests/TestAttribute.dfy > log2.txt
[xUnit.net 00:00:07.80]     DafnyTests/TestAttribute.dfy [FAIL]
Test Run Failed.

log2.txt.zip

[MikaelMayer]

Great, deleting that file actually seems to have solved the problem. I see in the log that it correctly outputs what was expected:

[xUnit.net 00:00:11.50]       Error:
[xUnit.net 00:00:11.50]       [xUnit.net 00:00:00.60]     _module.__default.FailingTest_CheckForFailureForXunit [FAIL]
[xUnit.net 00:00:11.50]       [xUnit.net 00:00:00.61]     _module.__default.FailingTestUsingExpectWithMessage [FAIL]
[xUnit.net 00:00:11.50]       [xUnit.net 00:00:00.61]     _module.__default.FailingTestUsingExpect [FAIL]
[xUnit.net 00:00:11.50]       [xUnit.net 00:00:00.61]     _module.__default.FailingTestUsingNoLHSAssignOrHalt [FAIL]
[xUnit.net 00:00:11.50]       [xUnit.net 00:00:00.61]     _module.__default.FailingTestUsingAssignOrHalt [FAIL]

. Now ensure the Output/ folder is empty again, remove the extra dotnet line that I made you add with the diagnostics, and run the test again. It should work.

[hmijail]

Something strange is happening...

At my first try at following your instructions, I found that the Output folder was no longer there at all, and the test (reverted to its original form) still failed anyway.

I thought to run make exe and see if would make the Output folder reappear. But it failed too!

So, in summary: yes, the test now passes, but it's sounding like the makefile / build process needs some scrubbing, and maybe it was even the original reason for the test failure?

[MikaelMayer]

What is the content of log3.txt that you created above? It contained the reason why it failed.

It looks like the first make exe was assuming that the jar runtime existed and because it failed to copy, that's what the test error was about.
Now it looks like make clean triggered something so that it forced make exe to regenerate the JAR.

I'm wondering what went wrong here.

Ugh, sorry, I overwrote that log3.txt file with the last successful run! If I find myself in that situation again I'll make sure to save it.

About the missing jar - this is not the first time I run make exe in the repo, so if it was ever created, it should still be there. I guess the question is, how did it get deleted?

[hmijail]

I suspect that the jar got deleted when at some point I started running the full set of tests by mistake and interrupted it with ^C while it was still building. I can see that during that building process, the jar is deleted and copied or rebuilt, so interrupting at that point might cause that problem maybe? Since then I ran only the TestAttribute test.

Looks like the tests and the general Dafny project have different or overlapping build systems, so maybe one of them can leave things in a state that the other doesn't understand, and make clean brought the state to a point common to both?

Relatedly, I just realized that if I try running the tests with the deprecated lit command, the problematic Output folder gets created again. So I guess those Output folders in my tree are remains from when lit was still the way to go.

All together, given that it looks like my tree is accumulating cruft because of deprecations and whatnot and that make clean doesn't do a deep clean, maybe I should just nuke the tree and clone the repo again?

[MikaelMayer]

Oh I did not realize that the lit command was creating these undesirable files for the dotnet test command.
That's why I got these errors on the first place too on my machine that were not in the CI, because I was working on both.
I think if it works and you are not using the lit test for this file again, you should be fine. I can't think yet of other things that might break.
Of course, if you clone the repo again, you'll have problems that are easier to reproduce, but I don't think it's a viable long-term solution.
