iOS testbed does not correctly handle test arguments with spaces #141442
Description
Bug report
Bug description:
The iOS testbed can be given arguments to pass to the test suite - for example:
$ python Apple/testbed clone myproject
$ python myproject run -- test arg1 arg2 'arg 3' arg4The arguments are then written into a test plan, and used to start the test suite.
The testbed runner correctly parses the command line arguments, and writes them into the test plan. However, even though Xcode's xctestplan format is a JSON document, and arguments are specified as an array, and arg 3 in the previous example is passed as a single quoted value in that array, Xcode itself does a raw concatenation of the array content. This means that any argument that contains a space is interpreted at runtime as multiple arguments.

This problem was introduced as part of #138018; that change introduced the use of the xctestplan, but it wasn't until I tried to run NumPy's test suite (which needs a
pytest -m 'not slow'configuration) that the problem became apparent.gh-141442: Add escaping to iOS testbed arguments (#141443)
