Description

Is it reproducible with SwiftPM command-line tools: swift build, swift test, swift package etc?

  • Confirmed reproduction steps with SwiftPM CLI. The description text must include reproduction steps with either of command-line SwiftPM commands, swift build, swift test, swift package etc.

Description

Run swift package init --type executable --enable-swift-testing.

Expected behavior

Tests directory that was created should have a corresponding test target in Package.swift

Actual behavior

Package.swift has not corresponding test target.

Research direction
The issue is that the ` enable swift testing` flag for `swift package init type executable` creates a Tests directory but does not add a corresponding test target to Package.swift. To fix, examine the template generation code in the SwiftPM repository, likely in `Sources/PackageModel/InitPackage.swift` or related files, where test targets are added conditionally. Ensure that when ` enable swift testing` is used, a test target is included in the generated Package.swift. Look at the `InitPackage` class and its methods for handling test targets, and consider similar logic used for other template types.
