The app ships on Electron (ABI 140), so `npm run rebuild:electron` produces an Electron-ABI binary the vitest runner (Node, ABI 137) cannot dlopen — the metrics store then degrades to a no-op and the assertions can't run. Probe the binding once and describe.skip WITH A LOGGED REASON when it can't load under the runner, instead of silently passing against a disabled store. Full logic still runs whenever the runner ABI matches the built binary. --- tests/renderer/wallet-setup.test.tsx | 13 +++++++-- tests/unit/metrics.test.ts | 43 +++++++++++++++++++++++++++- 2 files changed, 53 insertions(+), 3 deletions(-) diff --git a/tests/renderer/wallet-setup.test.tsx b/tests/renderer/wallet-setup.test.tsx index 42e98c4..93553f5 100644 --- a/tests/renderer/wallet-setup.test.tsx +++ b/tests/renderer/wallet-setup.test.tsx @@ -81,9 +81,18 @@ describe('WalletSetup', () => { expect(initBtn).toBeDefined(); await user.click(initBtn!); - // Mnemonic is revealed as 24 individual word tiles; assert the first - // word renders.
