throw should be throwing an exception rather than just a string, which is why the deprecation message is a bit confusing.
So instead of the line https://github.com/diegozea/MIToS.jl/blob/master/src/MSA/IndexedVectors.jl#L49 you’d want to have something like throw(ArgumentError("$element is more than one time in the vector.")) or some other error type rather than ArgumentError if that’s not appropriate for the situation. See the docs, http://docs.julialang.org/en/latest/manual/control-flow/#the-throw-function, for a list of all the builtin ones. Then in your tests you can do @test_throws ArgumentError IndexedVector([1, 2, 3, 3]) — Mike On Thursday, 6 August 2015 04:51:33 UTC+2, Diego Javier Zea wrote: > > > *What is the correct way for testing* > throw(message) > *?* > > *I'm getting this errors using test_throws. ¿What am I doing wrong?
