actionability | Auto-waiting |
Playwright performs a range of actionability checks on the elements before making actions to ensure these actions
behave as expected. It auto-waits for all the relevant checks to pass and only then performs the requested action. If the required checks do not pass within the given timeout
, action fails with the TimeoutError
.
For example, for [method: Page.click
], Playwright will ensure that:
- element is Attached to the DOM
- element is Visible
- element is Stable, as in not animating or completed animation
- element Receives Events, as in not obscured by other elements
- element is Enabled
Here is the complete list of actionability checks performed for each action:
Action | Attached | Visible | Stable | Receives Events | Enabled | Editable |
---|---|---|---|---|---|---|
check | Yes | Yes | Yes | Yes | Yes | - |
click | Yes | Yes | Yes | Yes | Yes | - |
dblclick | Yes | Yes | Yes | Yes | Yes | - |
setChecked | Yes | Yes | Yes | Yes | Yes | - |
tap | Yes | Yes | Yes | Yes | Yes | - |
uncheck | Yes | Yes | Yes | Yes | Yes | - |
hover | Yes | Yes | Yes | Yes | - | - |
scrollIntoViewIfNeeded | Yes | - | Yes | - | - | - |
screenshot | Yes | Yes | Yes | - | - | - |
fill | Yes | Yes | - | - | Yes | Yes |
selectText | Yes | Yes | - | - | - | - |
dispatchEvent | Yes | - | - | - | - | - |
focus | Yes | - | - | - | - | - |
getAttribute | Yes | - | - | - | - | - |
innerText | Yes | - | - | - | - | - |
innerHTML | Yes | - | - | - | - | - |
press | Yes | - | - | - | - | - |
setInputFiles | Yes | - | - | - | - | - |
selectOption | Yes | Yes | - | - | Yes | - |
textContent | Yes | - | - | - | - | - |
type | Yes | - | - | - | - | - |
Forcing actions
Some actions like [method: Page.click
] support force
option that disables non-essential actionability checks,
for example passing truthy force
to [method: Page.click
] method will not check that the target element actually
receives click events.
Assertions
You can check the actionability state of the element using one of the following methods as well. This is typically not necessary, but it helps writing assertive tests that ensure that after certain actions, elements reach actionable state:
- [
method: ElementHandle.isChecked
] - [
method: ElementHandle.isDisabled
] - [
method: ElementHandle.isEditable
] - [
method: ElementHandle.isEnabled
] - [
method: ElementHandle.isHidden
] - [
method: ElementHandle.isVisible
] - [
method: Page.isChecked
] - [
method: Page.isDisabled
] - [
method: Page.isEditable
] - [
method: Page.isEnabled
] - [
method: Page.isHidden
] - [
method: Page.isVisible
] - [
method: Locator.isChecked
] - [
method: Locator.isDisabled
] - [
method: Locator.isEditable
] - [
method: Locator.isEnabled
] - [
method: Locator.isHidden
] - [
method: Locator.isVisible
]
Attached
Element is considered attached when it is connected to a Document or a ShadowRoot.
Visible
Element is considered visible when it has non-empty bounding box and does not have visibility:hidden
computed style. Note that elements of zero size or with display:none
are not considered visible.
Stable
Element is considered stable when it has maintained the same bounding box for at least two consecutive animation frames.
Enabled
Element is considered enabled unless it is a <button>
, <select>
, <input>
or <textarea>
with a disabled
property.
Editable
Element is considered editable when it is enabled and does not have readonly
property set.
Receives Events
Element is considered receiving pointer events when it is the hit target of the pointer event at the action point. For example, when clicking at the point (10;10)
, Playwright checks whether some other element (usually an overlay) will instead capture the click at (10;10)
.
For example, consider a scenario where Playwright will click Sign Up
button regardless of when the [method: Page.click
] call was made:
- page is checking that user name is unique and
Sign Up
button is disabled; - after checking with the server, the disabled
Sign Up
button is replaced with another one that is now enabled.
