所以我理解流利和明確的等待,但我永遠無法得到隱含的陳述去工作。我設法不使用表達式來處理它們,但是我設計了一個相當簡單的測試,但它只適用於Thread.sleep,並且我絕對HATE該方法,並且不惜一切代價避免它。所以我試圖再次隱式等待函數...失敗。我的代碼Thread.sleep有效,但不是隱式等待?

的用了Thread.Sleep下面的代碼按預期工作,是偉大的

在隱式等待中使用TimeUnit.SECONDS而不是毫秒。快速瀏覽你的代碼表明你已經使用了100毫秒的隱式等待,這是非常標稱的,而在明確的等待中分配了3秒。

driver.manage().timeouts().implicitlyWait(3, TimeUnit.SECONDS);//waits for 3 seconds 

注意:顯式等待的單位是秒。

new WebDriverWait(driver, 10) //will wait for 10 seconds 

1000毫秒= 1秒

您應該使用3000ms內隱等待如果TIMEUNIT必須以毫秒爲單位。

據我所知,如果我使用3秒的隱式WebDriverWait爲10秒,那麼它會運行約13秒,取決於WebDriverWait的正確性?所以無論如何我改變了我的代碼是3秒,它似乎仍然沒有工作。相同的跟蹤堆棧 – Potion

您不需要使用隱式等待和顯式等待。此外,隱式和顯式等待不會加起來!一旦聲明瞭隱式等待,瀏覽器將在拋出異常之前等待x秒。 – prithvi394

所以我甚至不應該隱式等待,只使用我的原始代碼? – Potion
