1 year ago Can we use something like this as a regression test?
import log
import time
import vwebui as ui
fn wait_condition(max_iterations int, sleep_duration time.Duration, cb fn() bool) bool {
for i in 0 .. max_iterations {
if cb() {
return true
}
time.sleep(sleep_duration)
}
return false
}
struct App {
mut:
fn_was_called bool
}
fn allocate_lots_of_memory() {
log.info('allocate_lots_of_memory start')
for _ in 0..1000 { _ := 'abdef'.repeat(1000) }
log.info('allocate_lots_of_memory end')
}
fn test_fn_call() {
log.info('> ${@METHOD} start')
defer {
log.info('> ${@METHOD} end')
}
allocate_lots_of_memory()
mut app := &App{}
w := ui.new_window()
defer {
log.info('>> destroying window')
w.destroy()
}
w.bind('v_fn', fn [mut app] (e &ui.Event) {
log.info('>>> v_fn called')
defer {
log.info('>>> v_fn ended')
}
allocate_lots_of_memory()
assert e.string() == 'foo'
app.fn_was_called = true
})
w.show('<html style="background: #654da9; color: #eee">
<head><script src="/webui.js"></script></head>
<body>
<samp>test_fn_call</samp>
<script>setTimeout(async () => { await webui.call("v_fn", "foo"); }, 1000)</script>
</body>
</html>') or {
assert false, 'Failed at w.show'
}
// Wait for the window to show
ui.set_timeout(30)
if !wait_condition(300, 100 * time.millisecond, fn [w] () bool { return w.is_shown() }) {
assert false, 'Timeout showing window.'
}
log.info('> w.is_shown: ${w.is_shown()}')
if !wait_condition(300, 100 * time.millisecond, fn [mut app] () bool { return app.fn_was_called }) {
assert false, 'Timeout while waiting for the v binded callback to be called'
}
}
