Test a Swift package

Run tests for a single Swift package. Use this when you only need to test a specific package — use /test instead when you need to run the entire app's test suite.

Testing is a two-step process: build with warnings-as-errors first, then run tests with --skip-build.

Xcode MCP (preferred)

•Run mcp__xcode__XcodeListWindows to get the tabIdentifier for the Popcorn workspace.
•Run mcp__xcode__GetTestList to find test targets for the package.
•Run mcp__xcode__RunSomeTests with the relevant test specifiers for the package's test targets.

Fallback

Run from the package directory:

code

cd <package-dir> && set -o pipefail && swift build --build-tests -Xswiftc -warnings-as-errors 2>&1 | xcsift -f toon --Werror && set -o pipefail && swift test --skip-build 2>&1 | xcsift -f toon

Note: The build step uses -Xswiftc -warnings-as-errors and --Werror. The test execution step does not — consistent with how the app-level make test works.

Examples

bash

# Context package
cd Contexts/PopcornMovies && set -o pipefail && swift build --build-tests -Xswiftc -warnings-as-errors 2>&1 | xcsift -f toon --Werror && set -o pipefail && swift test --skip-build 2>&1 | xcsift -f toon

# Adapter package
cd Adapters/Contexts/PopcornMoviesAdapters && set -o pipefail && swift build --build-tests -Xswiftc -warnings-as-errors 2>&1 | xcsift -f toon --Werror && set -o pipefail && swift test --skip-build 2>&1 | xcsift -f toon

# Feature package
cd Features/MovieDetailsFeature && set -o pipefail && swift build --build-tests -Xswiftc -warnings-as-errors 2>&1 | xcsift -f toon --Werror && set -o pipefail && swift test --skip-build 2>&1 | xcsift -f toon
