XCTest results aren't correct when you have identical XCTestSuites in different test targets

[plemarquand]

On non Darwin platforms, XCTest results aren't correct when you have identical XCTestSuites different test targets.

To Reproduce

Create a test project with two test targets defined.

// Package.swift
...
targets: [
  .target(name: "TestApp"),
  .testTarget(name: "TestTarget1"),
  .testTarget(name: "TestTarget2"),
]

And create two test suites, one in each target.

// TestTarget1/TestFoo.swift
final class MyTestSuite: XCTestCase {
  func testFoo() {}
}

// TestTarget2/TestFoo.swift
final class MyTestSuite: XCTestCase {
  func testFoo() {}
}

Now select both test suites in the Test Explorer and run both. Notice only one test is marked as passing. This stems from the fact that unlike on macOS, on non Darwin platforms the test target is not included in the test run output.

Expected behavior
Both tests show as passing.

Environment

• OS: Ubuntu 20.04
• Swift version: Swift version 6.0-dev (LLVM 31f0cdc6d5ff8a6, Swift 497b266c2188eae)
• Visual Studio Code version: 1.92.2
• vscode-swift version: 1.10.7

Additional context

Here is the console output for a single suite run on Ubuntu

Test Suite 'MyTestSuite' started at 2024-08-27 20:23:17.188
Test Case 'MyTestSuite.testFoo' started at 2024-08-27 20:23:17.188
Test Case 'MyTestSuite.testFoo' passed (0.0 seconds)
Test Suite 'MyTestSuite' passed at 2024-08-27 20:23:17.188

And the same run on macOS:
