MetaTesting.jl

MetaTesting is a collection of utilities for testing "testers," functions that run tests. It is primarily intended as a test dependency.

Example

First we define a tester:

using Test

function test_approx(x, y)
    @test x ≈ y
end

Then we test it using MetaTesting:

using MetaTesting

@testset begin
    # test that tester correctly passes
    test_approx(1.0, 1.0)

    # test that tester correctly fails
    @test fails() do
        test_approx(1.0, 2.0)  # args not approximately equal
    end

    # test that tester correctly errors
    @test errors() do
        test_approx(1.0, (2.0,))  # isapprox not defined for this pair of types
    end
end
