Checkpoint: Testing Strategy

Question 1 of 5

• A 500-row table of every format you can think of.
• expect(() => parseAmount('abc')).toThrow()
• expect(parseAmount('12')).toBe(1200) under a different name.
• A Playwright test of the whole expense form.

Question 2 of 5

• The v8 provider cannot measure that file.
• The file is fully covered, so it is hidden.
• Coverage thresholds filter out files below the limit.
• coverage.include is not set, so only files loaded by the tests are reported.

Question 3 of 5

• Saving an expense with amountCents: 0 must reject.
• Saving an expense with amountCents: -100 must reject.
• Saving an expense with amountCents: 4500 must resolve.
• Saving an expense with amountCents: 12.5 must reject.

Question 4 of 5

• needs: e2e
• retention-days: 30
• if: ${{ !cancelled() }}, so it runs even after a failed test step.
• --shard=1/1 on the test command.

Question 5 of 5

• That lodash’s sortBy sorts expenses by date.
• That the error message has the class text-red-600.
• That a private helper is called exactly twice.
• That one leftover cent goes to the first person in the split.
