how to stop compilation if tests fail?

[spiral jewel]

i'm trying to modify my zig build run setup so that if tests fail, the app won't run.
but it only tells me that tests fail after i let the app normally close

i know i can chain zig build test && zig build run but i'm wondering if i can let the build system do it for me instead of having to use two commands.

this is my test step code in build.zig

    const test_step = b.step("test", "Run unit tests");

    test_step.dependOn(&run_lib_unit_tests.step);
    test_step.dependOn(&run_exe_unit_tests.step);

    const run_cmd = b.addRunArtifact(exe);
    const run_step = b.step("run", "Run the app");
    run_step.dependOn(test_step);
    run_step.dependOn(b.getInstallStep());
    run_step.dependOn(&run_cmd.step);

remove the dependency on install step

Because test should depend on install right? (Maybe transitively through the run unit test steps

that did not do anything unfortunately.

here's my entire build script. minmized to only contaain the test and run code

pub fn build(b: *std.Build) !void {
    const target = b.standardTargetOptions(.{});
    const optimize = b.standardOptimizeOption(.{});

    const lib = b.addLibrary(.{
        .name = Constants.Root.exe_name,
        .root_module = b.createModule(.{
            .root_source_file = b.path("src/root.zig"),
            .target = target,
            .optimize = optimize,
        }),
    });
    b.installArtifact(lib);
    const exe = b.addExecutable(.{
        .name = Constants.Root.exe_name,
        .root_module = b.createModule(.{
            .root_source_file = b.path("src/main.zig"),
            .target = target,
            .optimize = optimize,
        }),
    });
    b.installArtifact(exe);

    const lib_unit_tests = b.addTest(.{ .root_module = lib.root_module,});
    const exe_unit_tests = b.addTest(.{ .root_module = exe.root_module,});

    const run_lib_unit_tests = b.addRunArtifact(lib_unit_tests);
    const run_exe_unit_tests = b.addRunArtifact(exe_unit_tests);

    const test_step = b.step("test", "Run unit tests");

    test_step.dependOn(&run_lib_unit_tests.step);
    test_step.dependOn(&run_exe_unit_tests.step);

    const run_cmd = b.addRunArtifact(exe);
    const run_step = b.step("run", "Run the app");
    run_step.dependOn(test_step);
    run_step.dependOn(&run_cmd.step);

    if (b.args) |args| {
        run_cmd.addArgs(args);
    }
}

Does it say test failed but still run?

[spiral jewel]

Yes, the tests fail after the run step is done (when the app exits)

[weary skiff]

What if you swap the order of adding the depends on?

So run added first then test

[spiral jewel]

does nothing unfortunately
