Swift-Testing Support for Macros?

Development Macros
5

The swift-syntax 600.0.0 prereleases contain a SwiftSyntaxMacrosGenericTestSupport modules that can be used to test macros using swift-testing.

Copying from the swift-syntax pending 600.0.0 release notes

  • SwiftSyntaxMacrosGenericTestSupport
    • A version of the SwiftSyntaxMacrosTestSupport module that doesn't depend on Foundation or XCTest and can thus be used to write macro tests using swift-testing . Since swift-syntax can't depend on swift-testing (which would incur a circular dependency since swift-testing depends on swift-syntax), users need to manually specify a failure handler like the following, that fails the swift-testing test: Issue.record("\($0.message)", fileID: $0.location.fileID, filePath: $0.location.filePath, line: $0.location.line, column: $0.location.column)
