Swift Packages: Linux Compatibility Testing

As the Swift on Linux and Swift Package Manager ecosystems mature, many authors of Swift packages want to enable their packages on Linux as well as Apple platforms. The growth of Server-Side Swift makes Linux an important target for many packages.

The first step is to run a package's unit tests on Linux, to verify it behaves as expected.

Enabling unit tests on Linux

Because Swift on Linux does not use the Objective-C runtime, the dynamic features that the XCTest unit testing framework uses to automatically discover testcases are not available.
