Test

Run tests and debug failures. Before writing tests, read docs/testing.org.

Running Tests

just test              # Full test suite
just test :e2e         # E2E tests only
just test :generative  # Generative tests only
just test :unit        # Unit tests only

REPL-Based Testing

For rapid iteration (requires nREPL on port 9999):

;; Run all tests in a namespace
(require '[clojure.test :refer [run-tests]])
(run-tests 'bits.foo-test)

;; Run a single test
(require '[clojure.test :refer [test-var]])
(test-var #'bits.foo-test/my-test)

;; Reload and test
(require '[bits.foo :as foo] :reload)
(run-tests 'bits.foo-test)

Test Writing Conventions

BANNED:

• Arbitrary Thread/sleep — use condition-based waits
• println in test helpers — return data, assert with is
• Visual selectors (color classes) — use ARIA attributes

REQUIRED:

• Tests use ^:e2e or ^:generative metadata for filtering
• Customize test system with assoc-in, never add params to t/system
• Check semantic state via ARIA, not visual presentation

Debugging Failures

Generative Test Failures

The log shows the shrunk failing sequence:

Failed: [[[:type :number "aAA"] ...]]

Reproduce in REPL:

(require '[bits.form.gen-test :as gen-test])
;; Execute the shrunk actions manually

E2E Test Failures

Common patterns:

Pattern	Cause
Timeout (7):	Element/condition didn't appear
aria-busy stuck	Form validation not completing

Browser screenshots are uploaded as CI artifacts on failure.
