`cabal test` does no longer direct stdout to log file?

[jwaldmann]

Describe the bug

cabal test used to redirect stdout to the log file, but no longer does this?

To Reproduce

$ cabal unpack ersatz-0.5
$ cd ersatz-0.5
$ cabal test hunit

Expected behavior

with cabal-install version 3.10.2.1 , output is

...
Running 1 test suites...
Test suite hunit: RUNNING...
Test suite hunit: PASS
Test suite logged to:
/home/waldmann/tmp/ersatz-0.5/dist-newstyle/build/x86_64-linux/ghc-9.8.2/ersatz-0.5/t/hunit/test/ersatz-0.5-hunit.log
1 of 1 test suites (1 of 1 test cases) passed.

and the log file contains actual test output.

Observed behaviour

with cabal-install version 3.11.0.0, output is

...
Running 1 test suites...
Test suite hunit: RUNNING...
unit tests:
  unconstrained literals: [OK]

         Test Cases  Total 
 Passed  1           1     
 Failed  0           0     
 Total   1           1     
Test suite hunit: PASS

1 of 1 test suites (1 of 1 test cases) passed.

and the mentioned log file contains only

Test suite hunit: RUNNING...
Test suite hunit: PASS
Test suite logged to: /home/waldmann/tmp/ersatz-0.5/dist-newstyle/build/x86_64-linux/ghc-9.8.2/ersatz-0.5/t/hunit/test/ersatz-0.5-hunit.log

and NOT the actual test output.
