test: build cmuxTests without a Swift module in scripts/test-unit.sh - #14378
Merged
Merged
Conversation
CI stopped emitting the cmuxTests module in #14364, which took a one-test-file rebuild from 31 s to 4.1 s. The local test-compile wrapper now passes the same cmuxTests-only settings. CMUX_TEST_EMIT_MODULE=1 keeps the module for lldb. The compile-settings test checks that the wrapper and the CI script agree. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

- Around line 341-343: Update the cmuxTests values assertion in the test to
compare both ci_values and local_values against the expected
INTEGRATED_DRIVER=NO and SWIFT_FLAGS=-no-emit-module-separately values, while
retaining the existing equality and xcodebuild-argument checks.
- Line 349: Update the opt-out assertion in the test around STUB_XCODEBUILD_ARGS
so it detects all four no-module settings, including the
SWIFT_USE_INTEGRATED_DRIVER and OTHER_SWIFT_FLAGS expressions, and fails if any
are present.

Assert the expected cmuxTests values for both commands.
The current test can pass when both commands change INTEGRATED_DRIVER=NO to INTEGRATED_DRIVER=YES, or when both omit SWIFT_FLAGS=-no-emit-module-separately. Compare each captured output with the expected values.

Assert that all four no-module settings are absent in opt-out mode.
