# Go table-driven tests
When adding tests in this codebase:
1. **Stay offline.** Use `mockllm` + `memfs` (or a `t.TempDir()` for file-backed
adapters). Never hit a live model or the network in a test.
2. **Prefer table-driven cases** for any behaviour with multiple inputs:
```go
func TestThing(t *testing.T) {
cases := []struct {
name string
in string
want string
}{
{name: "empty", in: "", want: ""},
{name: "basic", in: "x", want: "X"},
}
for _, tc := range cases {
t.Run(tc.name, func(t *testing.T) {
if got := Thing(tc.in); got != tc.want {
t.Errorf("Thing(%q) = %q, want %q", tc.in, got, tc.want)
}
})
}
}
```
3. **Assert error results, not panics.** Tool-level failures come back as an
error `ToolResult` (`res.IsError`), not a Go error — check the result.
4. Run the suite with `task test` (which uses `-race`).
