cypress-drag-drop
A Cypress child command for drag'n'drop support.
Setup
Install using npm:
npm install --save-dev @4tw/cypress-drag-drop
or yarn
yarn add --dev @4tw/cypress-drag-drop
Before Cypress is loaded (usually in your commands.js
) put the following line:
require('@4tw/cypress-drag-drop')
Or, if you are using ES module syntax:
import '@4tw/cypress-drag-drop'
This will register the drag
and move
command.
If you're using TypeScript, put the following configuration in a tsconfig.json
{
"compilerOptions": {
"types": ["cypress", "@4tw/cypress-drag-drop"]
}
}
Usage
drag
The drag
command is a child command.
The command only accepts elements.
As the drop target simply pass a selector as a string.
In your Cypress spec use the command as follows:
describe('Dragtest', () => {
it('should dragndrop', () => {
cy.visit('/yourpage')
cy.get('.sourceitem').drag('.targetitem')
})
})
Pass the options as an object in the second paramteter.
describe('Dragtest', () => {
it('should dragndrop', () => {
cy.visit('/yourpage')
cy.get('.sourceitem').drag('.targetitem', options)
})
})
During the drag and drop interaction, two elements are involved. The source element being dragged and the drop target.
In order to decide what options should either be applied to the source or the target, the options object can be divided in source
and target
. Options that are not specific to the source or target are applied to both the source and the target.
cy.get('.sourceitem').drag('.target', {
source: { x: 100, y: 100 }, // applies to the element being dragged
target: { position: 'left' }, // applies to the drop target
force: true, // applied to both the source and target element
})
The options are directly passed to Cypress' trigger
command.
So, all options from https://docs.cypress.io/api/commands/trigger#Arguments are possible.
Check command outcome
The drag
command is able to tell whether the drag attempt was successful or not. So, the command will yield true
when the drag attempt was successful and false
otherwise:
cy.get('.sourceitem').drag('.target').then((success) => {
assert.isTrue(success)
})
Or you might also want to check that the element is not draggable:
cy.get('.sourceitem').drag('.target').then((success) => {
assert.isFalse(success)
})
move
The move
command is a child command.
The command only accepts elements.
Define deltaX
and deltaY
as an object parameter to move the element in x- and y-position relative to the element's current position.
In your Cypress spec use the command as follows:
describe('Movetest', () => {
it('should move', () => {
cy.visit('/yourpage')
cy.get('.sourceitem').move({ deltaX: 100, deltaY: 100 })
})
})
The command accepts all options from https://docs.cypress.io/api/commands/trigger#Arguments except position
, x
and y
because they have no effect, since the command makes use of clientX
and clientY
internally.
describe('Movetest', () => {
it('should move', () => {
cy.visit('/yourpage')
cy.get('.sourceitem').move({ deltaX: 100, deltaY: 100, ...options })
})
})
Development
The plugin itself is implemented in the index.js
file.
Testing
The tests can be run using Cypress:
yarn test
The test fixtures are under src/examples/
. Using the setExample
Cypress command
the fixture is loaded and ready to run tests on. The first attribute in the setExample
command
is the name of the fixture which needs to be the filename of the component.
cy.setExample('NameOfTheComponent')
Release
Release a new version of this package:
