Trouble with File Upload Automation in Production Environment Using Cypress
I'm dealing with I'm relatively new to this, so bear with me... I'm working on a project and hit a roadblock. During development, I've been tasked with automating file uploads for a web application where users can submit documents. Using Cypress for this purpose has led to some unexpected challenges. Despite following community recommendations and best practices, the file upload feature behaves inconsistently in our production environment. The setup I'm using looks like this: ```javascript // cypress/integration/fileUpload.spec.js describe('File Upload Test', () => { it('should upload a file successfully', () => { cy.visit('/upload-page'); cy.get('input[type="file"]').attachFile('example.pdf'); // Using cypress-file-upload plugin cy.get('button[type="submit"]').click(); cy.get('.success-message').should('be.visible'); }); }); ``` Yet, in our CI/CD pipeline, the file uploads often fail without clear error messages. I’ve experimented with different file formats and sizes, but the results remain the same. Debugging sessions revealed that the file upload is successful locally, but it fails in our production environment. Using `cy.log()` to trace the upload process didn’t yield any useful insights. Additionally, I’ve explored alternative approaches, like using `cy.request()` to simulate the upload directly via API calls, but that caused issues with file validation on the server side: ```javascript cy.request({ method: 'POST', url: '/api/upload', form: true, body: { file: cy.fixture('example.pdf'), } }).then((response) => { expect(response.status).to.eq(200); }); ``` The response from the server indicates a 400 Bad Request, which further complicates debugging. Could this be a configuration issue related to our production server’s handling of multipart form data? Or perhaps there’s a specific setting in Cypress that I’m missing? Any insights or similar experiences would be greatly appreciated, as I’m eager to resolve this before our next deployment. My development environment is Linux. I'm working on a service that needs to handle this. Any help would be greatly appreciated! I'm on Ubuntu 20.04 using the latest version of Javascript.
