Cypress how to close window print dialog
In Cypress, automating the closing of the print dialog window is not directly supported since Cypress is designed to interact with web content within the browser and not the browser's native dialogs.
However, you can work around this limitation by using some platform-specific techniques or browser-specific features. Here are a couple of approaches you can try:
Use Cypress intercept: You can intercept the
window.print
function and prevent it from opening the print dialog. Here's an example:javascriptCypress.Commands.overwrite('window', (window, originalWindow) => {
const printStub = cy.stub().as('printStub');
const modifiedWindow = {
...window,
print: printStub,
};
return originalWindow(modifiedWindow);
});
// Perform actions that trigger the print dialog
// Close the print dialog by calling the printStub with the "window.close" function
cy.get('@printStub').then(printStub => {
printStub(window.close());
});
This intercepts the
window.print
function and replaces it with a stub function. Then, you can use thecy.stub
reference to close the print dialog by callingwindow.close()
.Use browser-specific features: Some browsers provide specific flags or settings to suppress the print dialog. For example, in Chrome, you can use the
--kiosk-printing
flag to bypass the print dialog. To use this approach, you can create a custom Cypress script that launches the browser with the desired flags. Here's an example:bash# In your custom Cypress script (e.g., custom-cypress.js)
const cypress = require('cypress');
const { spawn } = require('child_process');
const args = [
'run',
'--browser',
'chrome',
'--config',
'chromeWebSecurity=false',
];
const flags = [
'--kiosk-printing',
];
const cypressProcess = spawn('npx', [
'cypress',
...args,
'--',
...flags,
]);
cypressProcess.stdout.pipe(process.stdout);
cypressProcess.stderr.pipe(process.stderr);
cypressProcess.on('exit', code => {
process.exit(code);
});
This custom Cypress script runs Cypress with the Chrome browser and passes the
--kiosk-printing
flag to suppress the print dialog.
Please note that these approaches might have limitations or specific requirements depending on the browser and environment. It's important to thoroughly test and adapt them to your specific use case.
Remember to adjust the configuration and code as needed to fit your Cypress setup and requirements.
