Magento Testing Stage 1

Hello, we have developed a magento e-commerce website, and we have reached the stage where we need testing for: - high traffic - functional - performance - integration - compatibility - functional After the testing stage is complete, there might be more work to be done, as maintenance of the site. Our budget is between 3-4$ / hour. Detailed explanation of the first stage, which requires the first 3 testing methods: 1. High traffic testing: -checking the sent mail service used: if the server uses PHP to send emails, we need to switch to SMTP, because the web server we are currently using will block sent mails if they exceed a certain quota. -study of the server’s behaviour and a report written in excel based on the study, containing all the data extracted during the study and some suggestions for optimization 2. Functional Testing: - study of every function available on the website and logging it in an excel table + result of the testing -suggestions for optimization 3. Performance Testing: - testing the performances and logging the work in an excel table too -suggestions for optimization
