+Suite-v2 unhappy paths can use the same generic engine too:

+

+```text

+suite "v2/generic-failures"

+

+case "fake_compiler_expected_diagnostic"

+source "../../fixtures/invalid/fake_compile_fail_expected.f90"

+compiler "../../fixtures/fake_compilers/compile_fail.sh" => diagnostics

+expect-fail comments

+end

+

+case "armfortas_parse_error"

+source "../../fixtures/invalid/parse_error.f90"

+compiler armfortas => diagnostics

+expect-fail parser contains "expected entity name"

+end

+```
