Running package tests really slow

I’m a bit surprised that running unit tests for a simple trial package takes a lot fo time. I am wondering what I’m doing wrong. running

] test

in this example takes 36 seconds. Note that there is no computation involved whatsoever:

# trial/src/trial.jl
module trial

using JSON
using NLsolve
using FastGaussQuadrature
using Plots
using LaTeXStrings
using Interact
using DataFrames

end

# trial/test/runtests.jl
using trial
using Test

@testset "trial.jl" begin
    # Write your tests here.
    @test true
end

the manifest is huge, as a result of the packages used. is there anything I could do to speed this up?

doing a precompile or running this multiple times does not change the result. I thought we don’t have to recompile a bunch of packages upon running each test?

yeah, given your CPU spec, I’m not too surprised, in 1.6 this should improve, see this blog

oh, that’s a bummer. impossible to test like that.

if you’re testing when developing, use Revise.jl is easier. In a REPL, have a test.jl and includet(test.jl) it, then call a main_test() function over and over maybe, you get the idea.

this works surprisingly well! thanks. for all the poor folks as slow as me, here is what i did:

using Revise
includet("test/runtests.jl")

# test/runtests.jl
using Trial
using Test

function t1()
	# stuff that would previoulsy go into a @testset
        # i.e. the test body with @test statements etc
end

then I just do t1() on the REPL and it runs my tests. I change the package code of Trial and it is reflectd in the test outcome. :v:

If you’re doing that, make sure you add a call to t1() somewhere within your runtests.jl before committing. Otherwise when someone tries to do pkg> test YourPackage it will just define the t1() function but not actually run it.

yes, definitely! ideally i will revert back to doing the good old @testset setup in a plain runtests.jl script. this here is just for local testing and to avoid taking forever on each iteration. thanks!

I’d have thought that @jling meant that you can keep a long-running session and repeatedly include(test/runtests.jl), using Revise to track changes to the package you’re developing (which should happen automatically™ as long as you’ve deved the package you’re testing). If most of the time is spent loading/precompiling dependencies then just by keeping the process open you should be able to avoid paying that price every time you run the tests.

You might need to ] activate test; dev .. for that to work though (and not commit the changes to test/Project.toml)

did you mean include or includet here?

include, because you want to execute the code in the tests fresh each time. If you used includet on the tests, they’d only run again if the tests themselves changed, and then only the changed parts.

well, the assumption is you have a test_main() in your test.jl and you just run that. (which will only change when tests themselves changes anyways?)

Of course if you’re making changes primarily to another package, your test.jl will have using PkgA and thus covered by Revise’s includet?
