Output generated during execution of tests doesn't have colour

[giordano]

In v2.0.1:

I think it's a bit suspicious the color argument in

ParallelTestRunner.jl/src/ParallelTestRunner.jl

Lines 239 to 299 in 3aac7bb

	function runtest(f, name, init_code, color)
	function inner()
	# generate a temporary module to execute the tests in
	mod = @eval(Main, module $(gensym(name)) end)
	@eval(mod, import ParallelTestRunner: Test, Random)
	@eval(mod, using .Test, .Random)
	# Both bindings must be imported since `@testset` can't handle fully-qualified names when VERSION < v"1.11.0-DEV.1518".
	@eval(mod, import ParallelTestRunner: WorkerTestSet)
	@eval(mod, import Test: DefaultTestSet)
	Core.eval(mod, init_code)
	data = @eval mod begin
	GC.gc(true)
	Random.seed!(1)
	pipe = Pipe()
	pipe_initialized = Channel{Nothing}(1)
	reader = @async begin
	take!(pipe_initialized)
	read(pipe, String)
	end
	stats = redirect_stdio(stdout=pipe, stderr=pipe) do
	put!(pipe_initialized, nothing)
	# @testset CustomTestRecord switches the all lower-level testset to our custom testset,
	# so we need to have two layers here such that the user-defined testsets are using `DefaultTestSet`.
	# This also guarantees our invariant about `WorkerTestSet` containing a single `DefaultTestSet`.
	@timed @testset WorkerTestSet "placeholder" begin
	@testset DefaultTestSet $name begin
	$f
	end
	end
	end
	close(pipe.in)
	output = fetch(reader)
	(; testset=stats.value, output, stats.time, stats.bytes, stats.gctime)
	end
	# process results
	rss = Sys.maxrss()
	record = TestRecord(data..., rss)
	GC.gc(true)
	return record
	end
	@static if VERSION >= v"1.13.0-DEV.1044"
	@with Test.TESTSET_PRINT_ENABLE => false begin
	inner()
	end
	else
	old_print_setting = Test.TESTSET_PRINT_ENABLE[]
	Test.TESTSET_PRINT_ENABLE[] = false
	try
	inner()
	finally
	Test.TESTSET_PRINT_ENABLE[] = old_print_setting
	end
	end
	end

is unused.

As far as I understand, the problem is around
