Playwright can interact with HTML Input elements such as text inputs, checkboxes, radio buttons, select options, mouse clicks, type characters, keys and shortcuts as well as upload files and focus elements.

Text input

Using Locator.fill(value[, options]) is the easiest way to fill out the form fields. It focuses the element and triggers an input event with the entered text. It works for <input><textarea> and [contenteditable] elements.

// Text input
page.getByRole("textbox").fill("Peter");

// Date input
page.getByLabel("Birth date").fill("2020-02-02");

// Time input
page.getByLabel("Appointment time").fill("13-15");

// Local datetime input
page.getByLabel("Local time").fill("2020-03-02T05:15");

Checkboxes and radio buttons

Using Locator.setChecked(checked[, options]) is the easiest way to check and uncheck a checkbox or a radio button. This method can be used with input[type=checkbox]input[type=radio] and [role=checkbox] elements.

// Check the checkbox
page.getByLabel("I agree to the terms above").check();

// Assert the checked state
assertTrue(page.getByLabel("Subscribe to newsletter").isChecked());

// Select the radio button
page.getByLabel("XL").check();

Select options

Selects one or multiple options in the <select> element with Locator.selectOption(values[, options]). You can specify option value, or label to select. Multiple options can be selected.

// Single selection matching the value
page.getByLabel("Choose a color").selectOption("blue");

// Single selection matching the label
page.getByLabel("Choose a color").selectOption(new SelectOption().setLabel("Blue"));

// Multiple selected items
page.getByLabel("Choose multiple colors").selectOption(new String[] {"red", "green", "blue"});

Mouse click

Performs a simple human click.

// Generic click
page.getByRole("button").click();

// Double click
page.getByText("Item").dblclick();

// Right click
page.getByText("Item").click(new Locator.ClickOptions().setButton(MouseButton.RIGHT));

// Shift + click
page.getByText("Item").click(new Locator.ClickOptions().setModifiers(Arrays.asList(KeyboardModifier.SHIFT)));

// Hover over element
page.getByText("Item").hover();

// Click the top left corner
page.getByText("Item").click(new Locator.ClickOptions().setPosition(0, 0));

Under the hood, this and other pointer-related methods:

  • wait for element with given selector to be in DOM
  • wait for it to become displayed, i.e. not empty, no display:none, no visibility:hidden
  • wait for it to stop moving, for example, until css transition finishes
  • scroll the element into view
  • wait for it to receive pointer events at the action point, for example, waits until element becomes non-obscured by other elements
  • retry if the element is detached during any of the above checks

Forcing the click

Sometimes, apps use non-trivial logic where hovering the element overlays it with another element that intercepts the click. This behavior is indistinguishable from a bug where element gets covered and the click is dispatched elsewhere. If you know this is taking place, you can bypass the actionability checks and force the click:

page.getByRole("button").click(new Locator.ClickOptions().setForce(true));

Programmatic click

If you are not interested in testing your app under the real conditions and want to simulate the click by any means possible, you can trigger the HTMLElement.click() behavior via simply dispatching a click event on the element with Locator.dispatchEvent(type[, eventInit, options]):

page.getByRole("button").dispatchEvent("click");

Type characters

Type into the field character by character, as if it was a user with a real keyboard with Locator.type(text[, options]).

// Type character by character
page.locator("#area").type("Hello World!");

This method will emit all the necessary keyboard events, with all the keydownkeyupkeypress events in place. You can even specify the optional delay between the key presses to simulate real user behavior.

NOTE

Most of the time, Page.fill(selector, value[, options]) will just work. You only need to type characters if there is special keyboard handling on the page.

Keys and shortcuts

// Hit Enter
page.getByText("Submit").press("Enter");

// Dispatch Control+Right
page.getByRole("textbox").press("Control+ArrowRight");

// Press $ sign on keyboard
page.getByRole("textbox").press("$");

The Locator.press(key[, options]) method focuses the selected element and produces a single keystroke. It accepts the logical key names that are emitted in the keyboardEvent.key property of the keyboard events:

Backquote, Minus, Equal, Backslash, Backspace, Tab, Delete, Escape,
ArrowDown, End, Enter, Home, Insert, PageDown, PageUp, ArrowRight,
ArrowUp, F1 - F12, Digit0 - Digit9, KeyA - KeyZ, etc.
  • You can alternatively specify a single character you’d like to produce such as "a" or "#".
  • Following modification shortcuts are also supported: Shift, Control, Alt, Meta.

Simple version produces a single character. This character is case-sensitive, so "a" and "A" will produce different results.

// <input id=name>
page.locator("#name").press("Shift+A");

// <input id=name>
page.locator("#name").press("Shift+ArrowLeft");

Shortcuts such as "Control+o" or "Control+Shift+T" are supported as well. When specified with the modifier, modifier is pressed and being held while the subsequent key is being pressed.

Note that you still need to specify the capital A in Shift-A to produce the capital character. Shift-a produces a lower-case one as if you had the CapsLock toggled.

Upload files

You can select input files for upload using the Locator.setInputFiles(files[, options]) method. It expects first argument to point to an input element with the type "file". Multiple files can be passed in the array. If some of the file paths are relative, they are resolved relative to the current working directory. Empty array clears the selected files.

// Select one file
page.getByLabel("Upload file").setInputFiles(Paths.get("myfile.pdf"));

// Select multiple files
page.getByLabel("Upload files").setInputFiles(new Path[] {Paths.get("file1.txt"), Paths.get("file2.txt")});

// Remove all the selected files
page.getByLabel("Upload file").setInputFiles(new Path[0]);

// Upload buffer from memory
page.getByLabel("Upload file").setInputFiles(new FilePayload(
  "file.txt", "text/plain", "this is test".getBytes(StandardCharsets.UTF_8)));

If you don’t have input element in hand (it is created dynamically), you can handle the Page.onFileChooser(handler) event or use a corresponding waiting method upon your action:

FileChooser fileChooser = page.waitForFileChooser(() -> {
  page.locator("upload").click();
});
fileChooser.setFiles(Paths.get("myfile.pdf"));

Focus element

For the dynamic pages that handle focus events, you can focus the given element with Locator.focus([options]).

page.getByLabel("Password").focus();

Drag and Drop

You can perform drag&drop operation with Locator.dragTo(target[, options]). This method will:

  • Hover the element that will be dragged.
  • Press left mouse button.
  • Move mouse to the element that will receive the drop.
  • Release left mouse button.
page.locator("#item-to-be-dragged").dragTo(page.locator("#item-to-drop-at"));

Dragging manually

If you want precise control over the drag operation, use lower-level methods like Locator.hover([options]), Mouse.down([options]), Mouse.move(x, y[, options]) and Mouse.up([options]).

page.locator("#item-to-be-dragged").hover();
page.mouse.down();
page.locator("#item-to-drop-at").hover();
page.mouse.up();

NOTE

If your page relies on the dragover event being dispatched, you need at least two mouse moves to trigger it in all browsers. To reliably issue the second mouse move, repeat your Mouse.move(x, y[, options]) or Locator.hover([options]) twice. The sequence of operations would be: hover the drag element, mouse down, hover the drop element, hover the drop element second time, mouse up.
