Fuzz Test Failure #28

Open changlinli opened 8 months ago

changlinli commented 8 months ago

After updating the test dependency to add 

"elm-explorations/test": "2.0.0 <= v < 3.0.0"

and changing the implementation of tuple2 and tuple3 in tests/ColorTest.elm to the following:

tuple2 : Fuzzer a -> Fuzzer b -> Fuzzer ( a, b )
tuple2 a b =
    Fuzz.pair a b

tuple3 : Fuzzer a -> Fuzzer b -> Fuzzer c -> Fuzzer ( a, b, c )
tuple3 a b c =
    Fuzz.triple a b c

to allow the most recent versions of either elm-test or elm-test-rs to run tests, I got the following tests:


Running 8963 tests. To reproduce these results later,
run elm-test-rs with --seed 1137142392 and --fuzz 100

I'm not sure whether these tests are spuriously failing, whether this reflects a true bug, whether this reflects some error in how I've upgraded the tests (although I don't think this is the case), or whether this is a bug in elm-explorations/test.
