# Should / Expected Conditions

Pylenium's [*<mark style="color:orange;">**Driver**</mark>*](/driver-commands/should.md), [*<mark style="color:orange;">**Element**</mark>*](/element-commands/should.md), and [*<mark style="color:orange;">**Elements**</mark>*](/elements-commands/elements.should.md) objects each have a **`Should`** API that allows you to write fluent-like code to wait and check for any expected conditions.

For example, to check that an element is visible on the webpage, you would do this:

{% code title="Pylenium" %}

```python
def test_element_is_visible(py):
    py.visit("https://qap.dev")
    assert py.get("a[href='/about']").should().be_visible()
```

{% endcode %}

With Selenium, you normally use the **`ExpectedConditions`** class:

{% code title="Selenium" %}

```python
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.wait import WebDriverWait


def test_element_is_visible():
    driver = webdriver.Chrome()
    wait = WebDriverWait(driver, timeout=10)
    
    driver.get("https://qap.dev")
    element = wait.until(EC.visibility_of_element_located(By.CSS_SELECTOR, "a[href='/about']"))
    assert element.is_displayed()
```

{% endcode %}
