is duplicated by:

  • SR-11968 SwiftPM test discovery: creating extra tests in separate files causes build errors
  • SR-14512 Duplicate allTests array when extending a XCTestCase class on Linux

Issue Description:

When having tests in an XCTestCase class in extensions in multiple files while using --enable-test-discovery building the test target fails with:

[9/12] Compiling ExamplePackageTests ExampleTests.swift /package/.build/x86_64-unknown-linux/debug/testlist.derived/ExampleTests.swift:11:16: error: invalid redeclaration of '_allTests_ExampleTests' static let _allTestsExampleTests = [ ^ /package/.build/x86_64-unknown-linux/debug/testlist.derived/ExampleTests.swift:5:16: note: 'allTests_ExampleTests' previously declared here static let _allTests_ExampleTests = [

The attached example can be run with docker build .

The example has a test in the class definition itself and one in an extension. But the problem also appears when having an empty class definition and tests in 2 or more extensions each in their own file.
