From d027ad91f1bc0d6e4d514cc2309e99a1b86959a3 Mon Sep 17 00:00:00 2001 From: Tom Read Cutting Date: Sat, 23 Aug 2025 00:44:26 +0100 Subject: [PATCH 1/8] First pass TestSequence idea implementation This is kind of hacked together as "Test Sequence Example Test", the idea being this is an example of how a test sequence might be contructed for testing zar. Currently, the existing tests still exist, but the idea would be to replace them with this setup completely (allowing for the code to be majorly simplified). This will allow us to more easily test more features in the future. --- src/test.zig | 308 +++++++++++++++++++++++++++++++++++++++++---------- 1 file changed, 247 insertions(+), 61 deletions(-) diff --git a/src/test.zig b/src/test.zig index 6012a89..5d9acc7 100644 --- a/src/test.zig +++ b/src/test.zig @@ -12,10 +12,8 @@ const Archive = @import("archive/Archive.zig");
