Minimalistic package for testing values against data stored on disk.
using Test
using SnapTests
path = "hello1.txt"
write(path, "hello world")
@test matchsnap(path, "hello world")
@test matchsnap(path, "hi world!") # fail with a diff
@test matchsnap("does_not_exist", "hi world!") # ask for path creation
SnapTests.on_cmp_false = :ask # ask to update data on disk if test fails
SnapTests.on_cmp_false = :replace # silently replace data on disk if test fails
SnapTests.on_cmp_false = :return # default, matchsnap will just return false
# Customization
# Lets customize test so that instead of loading from disk, stuff gets looked up from a database
enterprise_db = Dict()
struct Lookup
key::Symbol
end
SnapTests.exists(l::Lookup, value) = haskey(enterprise_db, l.key)
SnapTests.load(l::Lookup, value) = enterprise_db[l.key]
SnapTests.save(l::Lookup, value) = (enterprise_db[l.key] = value)
@test matchsnap(Lookup(:key1), 1)
@test matchsnap(Lookup(:key2), 2)
@test matchsnap(Lookup(:key2), 2)
@test matchsnap(Lookup(:key2), 3) # failsOne drawback of writing values to a file instead of hard coding them in a test is that reading the test is less self contained.
To alleviate this, there are ways for various editors to quickly peek the contents of a file.
Using telescope one can bind the following to some keys:
require('telescope.builtin').find_files({ default_text=vim.fn.expand('<cfile>')})"- ReferenceTests.jl Compared to this package many more awesome features. But also heavier dependencies and hard to customize, especially if FileIO does not cover your use case.
