Hello Community,
I’m working on adding iOS platform support for SwiftXCTest. So I’ve have the
following proposals and would like to hear feedback from the community.
SwiftXCTest runs the tests in a way `XCTMain([ testCase(TestFoo.allTests) ])`.
XCTMain supports only Linux / FreeBSD / macOS. So I suggest introducing an API
that will provide a similar way of running tests as XCTMain, but in a case
using SwiftXCTest as a framework e.g. on iOS. It could be the same logic that
just returns exit code, when XCTMain just exits with this code.
The suggestion above (number 1) is good, but too simple for using SwiftXCTest
as a framework, since we only have exit code and debug logs. So my second
proposal is providing mechanism of initialising root test suite with array of
testCases (array of XCTestCaseEntry objects) with the same structure that
XCTMain does. This isn’t possible now since XCTestCaseSuite class that is used
to initialise root test suite (see XCTMain.swift line 80) is internal.
This proposal is because Swift has very poor reflection at the moment. So I
suggest creating a generator (pre-build script) for Swift test cases that for
example is able analysing concrete folder with swift files and generate e.g.
TestCases.swift file. This script is intended to be used manually.
Looking forward to any feedback.
Ilya
