gotestsum reports nonexistent errors

[fgm]

Here is the situation: tests succeed with go test, both on their own and in the embedded go test -json command for gotestsum, but when gotestsum is done, it reports one error where none exists; and what's more it returns with status 0.

# Testing with gotestsum
./bin/gotestsum -f standard-verbose -- -v -count=1 -race ./somepackage
# github.com/someorg/somepackage/some.test
=== RUN   TestFoo
=== RUN   TestFoo/bar
--- PASS: TestFoo (0.00s)
    --- PASS: TestFoo/bar (0.00s)
PASS
ok  	github.com/someorg/somepackage	2.586s

=== Errors

DONE 2 tests, 1 error in 4.981s

$ echo $?
0

# Testing with go test
$ go test                              -v -count=1 -race ./somepackage 
# github.com/someorg/somepackage/some.test
=== RUN   TestFoo
=== RUN   TestFoo/bar
--- PASS: TestFoo (0.00s)
    --- PASS: TestFoo/bar (0.00s)
PASS
ok  	github.com/someorg/somepackage	1.636s

$ echo $?
0

Tested on

• macOS Sonoma, Apple Silicon.
• Both with go 1.22.6 and 1.23.0.
• gotestsum version dev

Hello, thank you for the bug report! Errors come from any stderr that is emitted from the test binary. I don't see any lines in this example. Do you have some code I can run to reproduce?
