How do I get errors in the Cadence testing framework to print so they are easily readable?

When I run tests, I get errors like this:

I haven't been able to figure out how to pretty print test errors. I typically copy paste that and replace \n with enter but it's not very efficient

turbolent•5mo ago

it's just printing the value, which as a string in it which is the error message ah, I guess I.Test.Test.Error is actually defined by the test framework please open an issue in https://github.com/onflow/cadence-tools for now maybe just pipe the output into something that replaces the newline literals (\n) into newlines, e.g. | sed -e 's/\\n/\n/g' e.g. flow-c1 test --cover --covercode="contracts" tests/*.cdc | sed -e 's/\\n/\n/g'
