A Julia package that provides @test-like macros with more informative error messages.
The inspiration comes from python asserts, which customize their error message based on the type of unit test being performed; for example, by showing the differences between two sets or lists that should be equal.
PrettyTests exports drop-in replacements for @test that are designed to (a) provide concise error messages tailored to specific situations, and (b) conform with the standard Test interface so that they fit into to any unit-testing workflow.
The package requires Julia 1.7 or higher. It can be installed using Julia's package manager: first type ] in the REPL, then:
pkg> add PrettyTests
julia> @test_all [1, 2, 3] .< 2
Test Failed at none:1
Expression: all([1, 2, 3] .< 2)
Evaluated: false
Argument: 3-element BitVector, 2 failures:
[2]: 2 < 2 ===> false
[3]: 3 < 2 ===> false
julia> @test_sets [1, 2, 3] ∩ [2, 3, 4] == ∅
Test Failed at none:1
Expression: [1, 2, 3] ∩ [2, 3, 4] == ∅
Evaluated: L and R are not disjoint.
L ∩ R has 2 elements: [2, 3]
