A test assertion that compares two fixed literals, such as `expect(true).toBe(true)` or `assert True`. It cannot fail and proves nothing about the code.
Each example shows the exact code shape the rule is looking for, then the smallest version that keeps the intent without hiding risk or adding noise.
describe('applyDiscount', () => {
it('applies a percentage discount', () => {
applyDiscount(cart, 'SPRING10')
expect(true).toBe(true)
})
})Deterministic line match on test files: flags `expect(literal).toBe(literal)` and `assert.equal`/`assert.strictEqual(literal, literal)` with equal literals in JS/TS, and a bare `assert True` line in Python.
describe('applyDiscount', () => {
it('applies a percentage discount', () => {
const result = applyDiscount(cart, 'SPRING10')
expect(result.total).toBe(90)
})
})Call the code under test and assert on its output or effects.
Asked to add tests, agents sometimes produce placeholder assertions that make the suite pass without exercising the code under test.

Deterministic line match on test files: flags `expect(literal).toBe(literal)` and `assert.equal`/`assert.strictEqual(literal, literal)` with equal literals in JS/TS, and a bare `assert True` line in Python.
Assertions on values produced by the code under test, comparisons of unequal literals, and production (non-test) files are not flagged.
Part of aislop's test-quality checks, scored in the standard tier: a high-confidence test gap that does not break production directly.
