This PR detects when a Swift Testing run returns `EXIT_NO_TESTS_FOUND` and treats it as a successful test run. This change handles the change from swiftlang/swift-testing#536. Separately, the refactor in #7766 stops Swift Package Manager from reporting `"No matching test cases were run"` when XCTest has no tests matching passed `--filter` arguments. A third PR after these two have been merged will restore that functionality by collating results from both XCTest and Swift Testing. > [!NOTE] > Test coverage can be added after Swift Testing is in the Swift toolchain. This change partially resolves rdar://131704587.
…Testing enabled by default.) (#7766) This PR refactors the previously-experimental Swift Testing support logic so that only a single build product is produced when using both XCTest and Swift Testing, and detection of Swift Testing usage is no longer needed at compile time. On macOS, Xcode 16 is responsible for hosting Swift Testing content, so additional changes may be needed in Xcode to support this refactoring. Such changes are beyond the purview of the Swift open source project. Resolves rdar://120864035. --------- Co-authored-by: Pavel Yaskevich <xedin@apache.org>

@swift-ci please test |
This PR turns Swift Testing back off by default when running `swift package init` because it's not available in the toolchain yet and the package dependency may come as a surprise (also, it breaks CI, but who's counting?) Follow-up to #7766.

Updated to include #7783. |

@swift-ci please test Windows |
The enable/disable testing library options are no longer used by `swift build` and can be removed.

Explanation: Refactors the previously-experimental Swift Testing support logic so that only a single build product is produced when using both XCTest and Swift Testing, and detection of Swift Testing usage is no longer needed at compile time.
Scope: Implementation of Swift Testing/SwiftPM integration; touches mostly
swift testbut affectsswift buildandswift package initas well.Issue: N/A (tracked in Apple Radar)
Original PR: #7766, #7777, #7783, #7784
Risk: Moderate—refactors how we build and run tests.
Testing: Existing test coverage in the package as well as test coverage in the Swift Testing package; additional integration testing will be added once Swift Testing is in the toolchain.
